In the Aral Sea Basin on the territory which is located five states, water resources are used basically
for irrigation and water-power engineering. These water users demand different modes of
regulation of a river drain. In interests of water-power engineering – the greatest development of
the electric power and accordingly use larges parts of an annual drain of the rivers in winter the
cold period of year. For irrigation the greatest volume of water is required in the summer during
the vegetative period. Regulation of a river drain is thus carried out by the large reservoirs. Thus all
largest hydroelectric power stations are constructed in the countries of a zone of the drain formation
- in upstream the rivers Amu Darya and Sir-Darya – in Kyrgyzstan and Tajikistan and the main
areas of the irrigated lands are located in states of the down stream of the rivers – Kazakhstan,
Turkmenistan and Uzbekistan. Zeravshan - the Transboundary River in Uzbekistan and Tajikistan
by length of 877 km and the area of basin of 17.7 Th. km2. From total water intake of the
Zeravshan river make is 4834 to the Republic of Tajikistan to come only 253 Mln. m3 (5.23 %).
The area of the irrigated lands in the Zeravshan valley in the Tajikistan though not so large (about
20 Th. ha) but a tendency of its expansion by the assimilation of foothill territories is observed. It is
necessary to notice that for the Republic of Tajikistan is perspective the energy potential of
waterways of the Zeravshan river basin which according to [4 ] makes – 11.8 Bln. kWt∙h. In the
presence of such rich energy potential suspended to the Zeravshan river Basin in Sugd area huge
deficiency of the electric power is observed - 3-4 Bln. kWt∙h /year which is covered by import of
3
the electric power from the Republic of Uzbekistan. The intensive grows of the Tajikistan
population, presence of the large file of the fertile but not mastered lands suspended to upstream of
the Zeravshan river demands principal processing of economic use of the Zeravshan rivers scheme.
The mutual combination of interests of upstream and downstream countries of the Zeravshan River
is quite achievable by building of the cascade of Hydropower station (HPS) with regulation of the
river drain. It causes some discontent of the Republic of Uzbekistan connected by that realization of
programs on development of a hydropower potential of the river by building a number of the water
reservoirs leads to deficiency of water in vegetation period of agricultural crops. The cardinal
solution of the conflict situation between an irrigation and water-power engineering is the greatest
their joint development by building of new HPS with reservoirs. For water-power engineering it
means increase in production of cheap and ecological pure energy and for an irrigation – increase
of depth of long-term regulation of a drain and water security of already mastered lands, and also
possibility of development new. At presence of several HPS with reservoirs the top reservoir can
work only in power mode, the bottom reservoir of the same volume can regulated a drain up to
restoration of its natural regime. Especially it can provide drain regulation in interests of irrigation.
At presence not two but many quantities of HPS with reservoirs the situation even more will
improve. The solution of a problem of balanced use of two aspects: use of a hydroenergy potential
of the Zarafshon River with full satisfaction of requirements of agriculture on water demands the
deep feasibility report leaves on a plane of bilaterial negotiations of the adjoining countries. At the
present stage in Global climate change by the most important monitoring and a behavior estimation
hydro- and meteorological parameters of a river basin of Zarafshon to climate changes which
allows to plan and adapt development and water-power engineering and agriculture taking into
account forthcoming values of volume of the river water on immediate prospects is.

During this time, people rely on fossil fuels to meet fuel vehicles. However, fossil fuels are not
renewable and increasingly depleted. In modern times such as now, the demand for fuel continues
to rise and the world population is also increasing. On the other hand, the earth must also be
preserved. One solution is the use of bioethanol as a fuel substitute. Bioethanol is a liquid produced
from the fermentation of starch are broken down by microorganisms. In addition to
environmentally friendly, renewable fuel that will reduce harmful gases that cause global warming.
Alternative energy in the manufacture of bioethanol is to utilize the durian seeds. The starch
content in the seeds of the durian is high enough to be able to produce ethanol. Durian seeds had
43.6 percent starch content. In a research note that the results obtained from starch was 18.46
percent durian seed cotyledons exact section. Because the starch content in the seeds of the durian
is considered very high, it can be developed and used as bioethanol. Additionally the durian seeds
as bioethanol will add value to the durian fruit. Bioethanol durian seeds will be developed through
a strategy of rural industrial agribusiness (AIP).

According to the world wide experiences, the anaerobic process is recommended as the most
suitable one for treatment of the manure from the pig farms. The advantages of this method
are numerous: the emission of disagreeable odor is significantly reduced; produced biogas can be
used as a fuel or for generation of heat/electricity which economically valorize the
process; the composition of the nutrients in the stabilized fertilizer is almost the same as
the row waste; -emissions of methane are reduced. Considering the possible and applied
solutions as well as the experiences from the treatment of the manure and the wastewater
from the pig farms in Europe and all over the world, on one hand, and respecting the
local and specific features of the of cattle-breeding farm in Kanibadam district on the other
hand, the existing system for the treatment of the manure and waste water was analyzed
and a new solution was proposed. In the elaboration of the solution, important request was
to consider the existing situation and structures and to plan inclusion and upgrading of
those structures. It was decided to apply a technology with anaerobic digestion and biogas
production that can be used for energy generation. Republic of Tajikistan is one of the countries
of the Central Asia, 93% of territory which occupy by mountains, possesses unique stocks of
hydropower resources (527 Bln. kWt∙h). However many areas and administrative centers test an
acute shortage of the electric power especially in the winter period of year. It, first of all, is
5
connected by that the mountain relief and numerous mountain canyons create difficulties in
carrying out and electric main adjustment. In most cases formation of flows and flooding destroy
technical constructions and electricity transmission media. Nowadays maintenance of inhabitants of
mountain districts and industrial and agroindustrial objects by electric power is one of priority lines
of activity of power branch of Republic Tajikistan. Preliminary researches on a finding of
alternative energy sources have shown that in mountain districts there are rich potential stocks of
energy - the expanded network of cattle-breeding farm. For an estimation of possibility of use of
manure in reception of the electric power we choose a typical dairy-cattle-breeding complex in one
mountain areas of Tajikistan from 1200 goals of cattle. It has been established that at average
value of manure of 12 kg per day of one goal of cattle on a farm it is formed more than 14 tons of
manure that corresponds to 650 м3 biogas equivalent to 1300 kWt∙h to the electric power.

Pakistan is agriculture based country, with more than 47% of its population’s livelihood is
dependent on agriculture. The country earns 70 percent of its foreign exchange from agriculture
sector; the share of agriculture sector in GDP is 24 %. The country with estimated population of
190 million has been declared food insecure. Due to severe power shortage, high fuel prices
coupled with climate change is making the agriculture sector unsustainable. It is reported that there
are 1100000 tube wells across the country among which 2,50,000 tube wells are energized by
PEPCO system consuming 3000 MW of electricity. There is an increasing trend in installation of
tube-wells, with limited availability of grid-based electricity which results in shift toward diesel
tube-wells which are expensive and produces greenhouse gases (GHG). Depleting groundwater in
Wheat and rice growing areas further deteriorates the situation and making the farming system
unsustainable. Pakistan is blessed with solar and wind energy. According to National Renewable
Energy Laboratory (http://www.nrel.gov/international/ra_pakistan.html) Pakistan Solar radiation is
5 kWh / meter square /day in most of the agricultural areas which goes to 6.5 kWh / meter square /
day in Baluchistan. The renewable energy source can be used as energy source for tube-wells. This
paper is an attempt to assess the technical, financial and economic feasibility of Solar Irrigation
pumps use in Pakistan. The paper will assess technical feasibility based on pump used, groundwater
6
table measurement and water requirement for the Rabi and Kharif crops. Clean Development
Mechanism (CDM) for carbon emission reduction for using solar pumps will be used to assess the
environmental viability, whereas, the negative health impacts by of thermal power and diesel based
pumps will be used to incorporate the negative externalities. The financial feasibility and economic
viability will be assessed on the basis of cost benefit analysis. Finally, the paper will conclude with
the policy recommendations for the implementation of Solar power Irrigation pump use in Pakistan
with special focus on Pakistan’s energy policy.
O-5 THE BIODIESL PRODUCTION FROM RESIDUAL ANIMAL FAT USING
VARIOUS CATALYSTS
Adnan Skhawat Ali1*

Waste animal fat is considered a promising cheap alternative feedstock for biodiesel production
that does not compete with food items. In addition, using waste animal fat as a feedstock is
considered a waste management process. In order to contribute for a more sustainable biodiesel
production, its synthesis from animal fat through different catalysts (NA, NaOH & KOH) was
studied. The objective of the study was to utilize waste animal fat (beef & mutton) for biodiesel
production because it was cheap, easily available and renewable raw material. The
transesterification of animal fat with methanol and suitable catalyst (KOH) produces a biodiesel of
high quality with good conversion rate. The process is easily feasible but the economical viability
can be improved by reusing methanol and glycerin. Oil extracted from beef and mutton fat was
analyzed by Gas Layer Chromatography for its fatty acids composition. Both mutton and beef fat
showed 50-93% conversion rate of oil to biodiesel with 3:1 methanol to oil molar ratio and 1wt%
of different catalysts like potassium hydroxide, sodium metal and sodium hydroxide at 60oC.
Biodiesel produced after transesterification reaction was analyzed for flash point <135oC each,
kinematic viscosity 1.74 & 1.59cSt, density 0.840 & 0.835, pour point 59oF & 57.2
oF, calorific
value 11568.7 & 10907.4BTU/lb and water content 1.0991 & 1.1725%vol for mutton and beef
respectively. Properties of biodiesel were almost comparable to ASTM standards so it can be used
as a fuel in vehicles.

In the current work, response surface methodology (RSM), based on central composite rotatable
design (CCRD) was applied to establish the optimum conditions for the methanolysis of Canola
(Brassica napus) seed oil. Four process variables were evaluated at two levels (24 experimental
design): the methanol:oil molar ratio (3:1-12:1), the catalyst concentration in relation to oil mass
(0.25-1.25 wt% KOH), the reaction temperature (25-65C) and the alcoholysis reaction time (20-
120 min). Using RSM, quadratic polynomial equation was obtained by multiple regression analysis
for predicting transesterification. The results indicates that methanol-oil-molar ratio, catalyst
concentration and reaction temperature were the significant factors on the yield of fatty methyl
esters. The reaction conditions for transesterification of B. napus crude oil for the response at which
methyl esters content of the biodiesel were 95.7% was found to be 8:1 methanol-to-oil ratio, 0.97 %
catalyst concentration, 55 C reaction temperature and 70-min reaction time. A linear relationship
was observed between the observed and predicted values. The biodiesel produced in the present
study was analyzed by gas chromatography (GC), which showed that it mainly contained four fatty
acid methyl esters. The fuel properties of B. napus oil methyl esters (BOME), i.e. kinematic
viscosity, oxidative stability, cloud point, pour point, cold filter plugging point, flash point, ash
content, sulfur content, acid value and density were determined which were within the limit of
biodiesel standards such as ASTM D6751 and EN 14214.

Two-step transesterification process was studied for the production of biodiesel from non edible clean jatropha
curcas oil (CJCO) having high level of FFA content (11.32%). First step was the esterification with acid catalyst
and FFA content were reduced from 11.32% to 1.13%. Second step was alkali based transesterification to convert
pretreated oil to biodiesel. The yield of first and second step was 90.5% and 80.7% respectively. Biodiesel
produced by this process was completely miscible with petro-diesel in every proportion and found to be
environment friendly diesel because its exhausts contain lesser emissions of toxic and hazardous waste such as
CO2, SOx, NOx as compared to petro diesel .Physico-chemical study of blends of biodiesel and petro-diesel was
established which showed that blending reduced the density, specific gravity of biodiesel, flash point of petro-
diesel was improved (which made the diesel a safe fuel), lower calorific value of biodiesel was improved.

Energy is the blood in Country’s Life. Pakistan went through an extraordinary period of having surplus electricity
from the late 1990s to 2004-05. However, since then, the country has been facing an acute shortage of electricity.
Current energy crisis started in 2006-07 with a gradual widening in the demand and supply gap. These energy
crises have be considered to be the worst of all such power crises that Pakistan has faced since its inception. It is
generally believed that the present crisis is a self-imposed problem ensuing from years of bad management, rapid
growth in demand, lack of proper vision for future and poor policies. Unfortunately, the scale of the problem has
now grown beyond any immediate solution. The persistent shortage of electricity in the country has adversely
affected the national economy. Industrial production has been severely hit; and also triggered social unrest which
sometimes turns violent thus, creating law and order problems in many urban centers in the country. In this
situation Pakistan must concentrate on generation of an appreciable amount of energy through renewable energy
resources which have a huge potential. We have 346,000 MW of wind energy potential, 2.9 million MW of solar
energy potential, 4,500 MW of small hydel potential, 4,000 MW of cogeneration/biomass, 2,000 MW of
geothermal, 10,000 MW of off-grid applications and a large potential of alternative fuels. However, lack of
institutional, information base technical capacity, policy challenges, poor infrastructure and market access, lack of
social awareness, lack of investors and financial barriers required to be sorted out by long-term management and
utilization of these potential energy resources in Pakistan.

The prevalent occurrence of pharmaceuticals in aquatic environment and their increasing trend in
the aquatic environment has increased the concern of toxicologists and ecologists about the
impending threats to aquatic species. In this study, toxicity of 10 pharmaceutical compounds
(Acetylsalicylic acid, Amoxicillin, Carbamezepine, Clofibric acid, Diclofenac, Erythromycin,
Ibuprofen, Ofloxacin, Sulfamethoxazole and Triclosan) has been determined with regard to
bacterial 30-min bioluminescence inhibition, ciliates 48-h growth inhabitation and crustacean’s 48-
h acute immobilization employing Vibrio fischeri, Tetrahymena pyriformis, and Daphnia magna.
The results are discussed in terms of compound concentrations exerting 50% effect, EC50. For these
pharmaceutical compounds, the following EC50 value ranges have been observed: For Vibrio
fischeri (30-min bioluminescence inhibition) 6.00 × 10–07
M to 2.47 × 10–04
M, for Tetrahymena
pyriformis 8.00 × 10–07
M to 3.55 × 10
–03M, and for Daphnia magna (48-h immobilization) 9.57 ×
10–07
M to >3.42 × 10–03
M respectively. Employing narcosis models from literature for the
organisms and endpoints under analysis, toxicity enhancement (Te) values were derived as ratio of
its predicted narcosis EC50 over its experimentally determined EC50. The accordingly observed log
Te values ranged for Vibrio fischeri from –1.08 to 4.46, for Tetrahymena pyriformis from –0.65 to
2.20, and for Daphnia magna from –1.95 to 3.12, respectively. Interestingly, some pharmaceuticals
are even less toxic than baseline narcosis, suggesting an efficient metabolic detoxification. At the
same time, however, there are also pharmaceuticals with substantial toxicity enhancements, which
is most pronounced for Vibrio fischeri with a maximum Te value of almost 26,302. What has been
learned so for from this study, is that, it is critical to make a confident prediction about the
ecotoxicological effects of the pharmaceuticals in aquatic environment towards non-targeted
aquatic organisms. The effects are very heterogeneous as results showed in different classes of
pharmaceuticals towards the different organisms. The results even vary in a single class towards
11
due to the specific mode of action; every substance has its own fate in aquatic environment. Excess
toxicity (Te) values indirectly depend on the octanol/water partition coefficients, log Kow values,
toxicity increase by decreasing the log Kow values. The bioassay with Vibrio fischeri and Daphnia
magna both are useful tools to determine the toxicity of the pharmaceuticals as the both assays
showed correlation r2 = 0.746 rather than the Tetrahymena pyriformis, which showed least
sensitivity towards the pharmaceutical compounds by showing higher EC50 among all bioassays.

Heavy metals are available in different concentrations in the Earth crust and atmosphere. Heavy metals
accumulate in the soil, water, plants and sediments. These are stable and cannot be degraded. Plants and soil
are the cheapest way to study and explore the concentration of heavy metals. Present study was conducted to
examine the heavy metals pollution in two areas of district Attock. An attempt has been made to compare
the heavy metals concentrations (Cu, Pb, Cd, Ni, Zn) in a relatively less polluted site (Khour City) and a
polluted site (Khour Company). Samples of soil and plants were collected from both sites. From each site,
four points were selected randomly for vegetation and soil sampling. Plant species included Eucalyptus
camaldulensis, Calotropis procera, Ziziphus nummularia , Cynodon dactylon, Acacia senegal,
Parthenium hysterophorus, Dalbergia sissoo and Desmostachya bipinnata. Heavy metals were detected in
soil and vegetation of both areas. The Pb concentration was highest amongst other heavy metals in both soil
and vegetation. In studied plant species heavy metals concentrations varied among different species. The
level of heavy metal concentration in the area was in order Khour Company>Khour City. The increasing
level of heavy metal contamination in the Khour Company area may be because of higher traffic density and
industralization compared to Khour City.

The potential of mid infrared (MIR) spectroscopy in combination with partial least squares (PLS) regression was
investigated to estimate the total As content in soil samples collected from a highly variable arsenic-contaminated
cattle-dip site at Wollongbar in northern NSW, Australia. The principal component analysis (PCA) was performed
prior to MIR-PLS regression analysis that identified spectral outliers in the absorbance spectra of soil samples.
The MIR-PLS calibration model excluding (n = 149) the spectral outliers showed an acceptable reliability
(coefficient of determination, R2
c = 0.75; residual prediction deviation, RPDc = 2.02) to estimate total arsenic (As)
content in soil. For total As, the validation of final calibration model using a validation set (n = 149) of unknown
samples also resulted in a good acceptability with R2
v = 0.67 and RPDv = 1.68. The MIR-PLS based model can
provide a rapid estimate of total soil As content by taking into account the integrated effects of mineralogical and
organic components of soils. This approach can be useful to estimate total soil As in various conditions; for
example, where analysis of a large number of soil samples is required.

Bioaccumulation of the three heavy metals lead (Pb), copper (Cu) and nickel (Ni) was analyzed in
water as well as in different organs like gills, liver and intestine of the sample and control fish. The
fish (Cyprinus carpio and Labeo rohita) and water samples were taken for experimental work from
three polluted site whereas control samples of fish and water were taken from fish hatchery, Satina
Road, Faisalabad. The physiochemical parameters of polluted and control water were evaluated to
determine the difference of quality in habitat. It was observed that water temperature and total
solids were higher at polluted sites than control whereas water pH, dissolved oxygen and electrical
conductivity were low at polluted sites than control. In the control water the concentrations of
heavy metals ranged as Pb (0.14-1.34 mg/ l), Cu (0.15- 1.17 mg/ l) and Ni (0.15-1.08 mg/ l)
whereas in the polluted water these were (3.02-4.88 mg/ l), (1.87- 4.95 mg/ l) and (1.16- 1.22 mg/
l), respectively. Among the three different polluted water sites, site Ι exhibited significantly higher
mean concentration of Pb (4.41±0.24 m/l), Cu (4.87±0.03 mg/l) and Ni (1.22±0.01 mg/l). The
differences among all the three polluted sites for the Pb, Cu and Ni toxicity were significant (P <
0.05). The magnitude of Pb and Cu accumulation in organs of both the species of fish was liver >
gills >intestine. The liver, gills and intestine of Cyprinus carpio and Labeo rohita had showed
significant (P<0.001) differences in the amount of metal concentration. Both of the fish species at
three sites had the maximum concentrations of Cu in the liver, followed by the gills. However,
intestine was the organ that accumulated significantly lowest concentration of Cu. The gills
accumulated usually higher amount of Ni followed by the liver and intestine, respectively. Both
species showed the same pattern of bioaccumulation, but the difference was significant (P < 0.05).
Usually Cyprinus carpio had significantly higher (P > 0.05) level of metal concentrations at all
sites.

Waste generation has increased tremendously in developing countries due to population growth,
pattern of consumption and consumerism and other lifestyle changes. However, a large amount of
different categories of waste generated is disposed off in open dump sites without segregation at
source. The disposal of household organic waste continues along hazardous waste that could result
in making it more toxic and carcinogenic. It causes contamination through microbial byproducts
present in leachates and hence, deteriorates soil and ground water quality. This study was designed
to assess the effects of leachate on soil and water from aged open dump sites during pre- and post-
rain season in 2011-12. The ground water and soil samples were analyzed and evaluated for heavy
metals, organic compounds and other contaminants (APHA, 2005; Rayan et al., 2001). The
physico-chemical characterization of soil samples collected from open dumping sites of both
Sialkot and Gujranwala city confirmed the presence of macro inorganic components, high total
organic carbon, and heavy metals. The heavy metal concentration present in soil was in order of:
Zn>Fe>Cu>Cr>Ni>Cd>Co>Pb whereas As and Hg was not detected. As a whole, the site wise
contamination order was Gujranwala-B > Gujranwala-A whereas Sialkot-A >Sialkot-B.
Collectively, Gujranwala samples irrespective of water or soil were significantly contaminated as
compared to Sialkot samples. On the other hand, the damaging environmental prospect associated
with leaching of toxic chemicals was the contamination of adjacent water bodies and ground water.
It was found that most of the pre-rain samples had pH value near to or higher than WHO/NEQS
15
standards in both cities while TDS, EC, hardness, nitrate, sulfates, chlorides and phosphates
concentrations were found to be within WHO/NEQS permissible standards. The heavy metals (Zn,
Fe, Cu, Cr, Ni, Cd, Co and Pb) were detected in higher concentration than NEQS/WHO standards
in most of water samples. The presence of high concentration of heavy metals, i.e., Cd, Zn, Fe, Cr,
Cu, Ni was the indication of deleterious effects on ground water quality due to wate dumping sites.
Moreover, people living in that area are at risk of toxic effects of heavy metals due to accumulation
of metals in receipt of soils and release of concentrated leachate to the environment which further
become potential source of entry into the food web.

Pesticides are common pollutant of rural areas and are determent to people's health and
environment. About 2.5 million tons of pesticides per year are used worldwide to control the pests.
The use of pesticides is increasing with the passage of time due to increased demand of food from
growing population. The same trend of increased annual consumption of pesticides is observed in
Pakistan. In addition to protect plants from pests, pesticide use deteriorates soil physico-chemical
properties and microbial activities. In Pakistan, about 80% of total pesticides used are being
sprayed on cotton crops. Vehari, a cotton-growing heart of the Indus Valley, contributes 12-18 % to
the total cotton production of Pakistan. The district is also considered as the major utilizer of
pesticides. The increased use of pesticides in this area has caused several environmental concerns,
but are still unexposed due to lack of awareness in local community and facilities for analysis. The
present study was carried out to analyse pesticide percolation in Vehari region soil. The surface soil
samples are collected from 9 sites of cotton area in Vehari region (3 sites from each Tehsil, i.e.,
Vehari, Mailsi, Burrewala). Then the soil samples are analysed for chemical analysis (pH, texture,
total organic carbon and electrical conductivity) and pesticides contents. The four pesticides
analysed include: Acephate, Profenofos, Trichlorfon and Endosulfan.

Contaminants in fish are of particular interest not only because of potential risk to human as being
ultimate consumer but also for devastation of the meat quality. Water from River Chenab was
analyzed for water quality parameters (WQP) from three sampling sites designated as highly
polluted, less polluted and Control devoid of any pollution. These WQP were analyzed to find out
their effects on fish fatty acid profile. River water receiving Chakbandi drain, District Jhang
(31.570345° and 72.533798°) becomes highly polluted as witnessed through high levels of salinity,
conductivity, pH, BOD, COD, TDS, TSS, SO42-
and Phenols. Atomic absorption
spectrophotometery showed higher levels of contaminations for Cd, Hg, Cu, Mn, Zn, Pb, Cr and Sn
in the River water. Fatty acids in the fish meat were detected by gas chromatography using Flame
Ionization Detector. Fish from unpolluted environment showed higher levels of unsaturated fatty

from polluted and less polluted environment showed unsaturated fatty acids, as Catla catla (37%),
Labeo rohita (12%), Cirrhina mrigala (24%) and Catla catla (52%), Labeo rohita (31%), Cirrhina
mrigala (23%) respectively. Fatty acids C8:0, C12:0, C20:0, C16:1(n-7), C16:1(n-9), C20:1(n-9),
C18:2(n-6), C18:4(n-3), C20:5(n-3) and C22:4(n-6) were found missing in the flesh of fishes
obtained from area of higher pollution. Fatty acids C16:1(n-7), C20:1(n-9) and C20:5(n-3) were
exclusively found in considerable amount only in Catla catla, but missing in both Labeo rohita and
Cirrhina mrigala even in less polluted environment. Present study provided clear indication about
fish contamination accompanied by annihilation of omega fatty acids and quality of fish meat being
affected even because of lower intensity of pollution.

A study was designed to determine the quantities of heavy metals such as (Antimony, Cobalt,
Arsenic, Chromium, Sodium, Calcium, Lead, Aluminum, Iron) in water samples obtained from
tube wells having different depths in district Pishin, Baluchistan, Pakistan. A total of 50 fresh water
samples were collected and different parameters such as depth of tube well, location of tube well,
age of tube well, pH, electrical conductivity, population burden and use of fertilizers in the vicinity
of tube wells were correlated with the quantities of heavy metals. The study findings shows that
age of tube well had no impact on quantities of studied heavy metals. It was found that depth of
tube wells had significant impact on quantities of heavy metals, when compared with heavy metals
such as Iron, Antimony, Chromium and Aluminum the values were found to be higher in quantities
in tube wells of lower depth and as the depth of tube wells increased the contents of theses metals
decreased significantly. Chromium, Cobalt, Antimony, Iron and Aluminum were found in higher
concentration than standard recommended values. Arsenic was found in all samples collected from
tube wells of main Pishin city and chromium was found in all samples collected from tube wells
where fruit orchards were present. The presence of arsenic in the samples may be attributed to the
population burden, where as presence of chromium may be attributed to the use of chemical
fertilizers and pesticides in the vicinity of tube wells. In general it is concluded that the quantities of
heavy metals such as Iron, Aluminum, Antimony, Chromium and Cobalt were found in higher than
recommended level which is an alarming indication for the drinking water for public use. pH and
conductivity were found higher in shallow depths of tube wells.

This is the first attempt to determine the effect of polluted water on the vegetation of the Machia
and its allied area in Bhimber, Azad Kashmir during 2004-2005. For this investigation the highly
industrialized urban location of 500 Sq. meter polluted area was selected. It has 5-6 industries of
soap, steel, textile, pharmaceutical and leather, which are secreting polluted water in the affected
area. Heavy metal emissions in the isolated polluted area have detrimental effect on the vegetation
of 500 sq. meter selected area. The result reflects that the accumulations of heavy metals deposition
have eliminated the 94 species from the area and only fifteen species have flourished in the polluted
area. Floristic survey of the Machia and allied area indicates that there are 111 plant species present
belonging to 97 genera and 41 families including 83 herbs, 17 trees and 11 shrubs. Poaceae is the
dominant family following the Asteraceae. There are about 72 medicinal, 29 food and fodder, 19
are fuel and constructive plants with 14 vegetables. 15 species are resident to loamy, 200 ppm.
Potassium, 16 ppm. Phosphorous, 2.45% organic matter and 42% saturation. Trees have been
disappeared from the polluted area and most resistant species are, Datura, Innoxia, Ricinus
Communus, Cassia Obtuqifolia, Cynodon dactylon and Calatrotis procira. The biologically
effective results of pollution can only be determined by carrying out measurements on organization
themselves, the most suitable indicator organisms are plants. The polluted water in this area have
eliminated all the trees and 94 important plants of diverse utility from the area.

Our technology advances at incredible speed. Most of the development has definitely resulted in
global shrinkage. Today the amount of microwave our planet swims in far surpasses the output of
the sun. The energy associated with electromagnetic radiation (non–ionizing) is proportional to
frequency. The mobile phones and mobile towers sprouting are studied in the presentation .High
power transmission lines carrying current and passing over fields have effected cattle as strong
magnetic field is developed around , power frequency (50/60 Hz) are produced around wires.
Recent studies are showing that there is a significant decline in the number of bird sparrow and
honey bees which is also an outcome of microwaves. All vital organs have melatonin and serotonin
receptors, the studies have shown the reduction in melatonin in presence of strong fields. The
neurological effect and blood brain barrier disturbance has been studied in humans. .The study was
carried out at Kanpur (India) and data of leading cellular operators are compiled, which indicate the
rise in density of radiation in highly populated areas. Field survey data indicated some serious
disorders in humans who are sitting around or below the towers for around 10 hrs every day for
past 5 years. Even though more evidence is required before we draw a conclusion we can practice
some safe methodology to reduce the impact not only on us but on environment as whole.

Man’s influence on the earth and its resources has increased at an unprecedented rate since the advent of industrial
revolution in 18th
century. Human activities are now affecting some of the most basic climatic and biological
cycles of the planet. The increased use of natural resources for human needs generates solid wastes, toxic effluents
and gaseous emissions adversely affecting human and environment. The present study was conducted to
investigate and evaluate the impacts of industrial effluents of Small Industrial Estate, Kohat Road Peshawar, on
the quality of water, soils and plants in the adjoining area. Investigations were conducted to determine the
magnitude of heavy metals concentration in Industrial effluents, soils and plants and compared it with the National
Environmental Quality Standards (NEQS) for Industrial effluents and World Health Organization (WHO)
permissible limit of these metals in soils and plants respectively. Samples at three different sites i.e. Canal water
(CW), Industrial Effluents (IE) and Mixed water (MW) (Canal water + Industrial effluents + municipal waste)
were taken. Soil samples were collected at two (0-15 cm and 15-30 cm) depths. Results revealed that the
temperature, pH and total dissolved solids (TDS) values for all the three types of water were within the
permissible limit of NEQS, while values of total suspended solids (TTS) were higher. The Biological Oxygen
Demand (BOD) values were low for Canal water but exceeded the permissible limits of NEQS for IE and MW.
The concentration of Pb, Cu, Zn, Mn and Fe in soil irrigated with CW and MW exceeded WHO permissible limit
in 0% , 100%, 70%, 100%, 0% and 100 %, 100%, 100%, 100%, 40% at 0-15 cm depth respectively, whereas, at
the depth of 15-30 cm, the concentration were 0%, 100%, 70%, 100%, 0% and 50%, 100%, 100%, 100% and 20%
respectively. Plants receiving Canal water showed higher concentration of Cr, Cd, Pb, Ni, Zn, Mn and Fe, thereby
exceeding WHO permissible limit in 100%, 100%, 100%, 90%, 100% and 100%, while those irrigated with
Mixed water showed higher level in 100%, 100%, 100%, 100%, 100%, 100% and 80% respectively. The
concentration of Cr, Cd and Ni in soil at both the depths and that of Cu in plants for CW and MW of irrigation was
found within the permissible limit of WHO. It was revealed through interaction with the local people that the canal
water under study was not used for human consumption but was only used for irrigation purposes. The canal water
was also used for swimming in summer season by the local community, which caused diseases like dysentery,
typhoid fever and cholera. The results indicated that the amount of heavy metals in water in excess of the NEQS,
22
have certainly increased the concentration of most of the heavy metals in soil and plants. In conclusion it is
suggested that in order to avoid water, soil and plants pollution, the industrial effluents and municipal wastewater
should be treated before discharge to irrigation channels to irrigate the fields.

The effect of nitrogen forms on growth, photosynthesis and physiological processes of barley plants
under chromium stress was studied with a hydroponic experiment. The treatments consisted of three
chromium (Cr) levels (0, 75 and 100 µM) and three N forms ((NH4)2SO4, urea and Ca (NO3)2. N
forms in the absence of Cr had significant effect on plant growth, biomass, physiological and
biochemical changes. The Ca (NO3)2 fed plants had higher plant growth and biomass, followed by
urea. Cr stress caused a significant reduction in growth and biomass in all three N forms. In
comparison with the urea or (NH4)2SO4 fed plants, the Ca (NO3)2 fed plants had higher plant height,
dry biomass, tillers per plant, net photosynthetic rate (Pn), cellular CO2 concentration (Ci), stomatal
conductance (Gs) and transpiration rate (Tr), PAR utilization efficiency (PARUE), photosynthetic
efficiency (Fv/Fm), the contents of chlorophyll a, b, total chlorophyll and carotenoids, root
dehydrogenase activity. Cr toxicity caused oxidative stress in all three forms of N, while the
Ca(NO3)2 fed plants had less oxidative stress than the urea or (NH4)2SO4 fed plants. Moreover, the
Ca(NO3)2 fed plants had higher soluble protein, proline, free amino acid contents, activities of anti-
oxidative enzymes, including SOD, POD, APX, CAT and GR and contents of non-enzymatic
antioxidants, including GSH and ASC than the urea or (NH4)2SO4 fed plants. In addition, the
Ca(NO3)2 fed plants had higher N and lower Cr concentrations in all plant tissues than the urea or
(NH4)2SO4 fed plants. The conclusion is that Ca(NO3)2 is a better fertilizer for the Cr-contaminated
soils for barley production.

Construction of Technosols through assemblage of treated soil and recycled wastes is an innovative
option for the restoration of degraded lands and re-use of industrial wastes. Recent studies have
evidenced that Technosols could support soil functions such as primary production but the
knowledge about other ecosystemic services, such as nutrient cycling, is limited. In this work, we
investigated the abundance and the activity of microbial communities involved in N-cycling in
different horizons (0–15, 15–35, 35–70 cm) of two types of Technosols constructed to reclaim an
industrial wasteland. The estimation by real-time PCR of the abundances of the different microbial
guilds indicated a significant depth effect in both Technosols on the abundances of the total
bacterial and crenarchaeal community and of the ammonia-oxidizing and denitrifying communities.
Activity measurements revealed higher denitrification than nitrification rates, which were also
affected by Technosol depth. Potential denitrification and nitrification were correlated with
Technosol physicochemical properties but also with the abundances of the nirS denitrification gene
and bacterial amoA gene, respectively. The type of Technosols influenced both the abundance and
the activity of the denitrifier community but not the ammonia-oxidizers, which underlines the
importance of a better understanding of microbial communities in Technosols to maximize their
potential for fulfilling soil ecosystemic functions.

The amount and toxicity of domestic wastewater is increasing due to population explosion and
rapid urbanization. This untreated domestic wastewater is badly affecting the ecosystem. In the
present study, we have tried to develop activated carbon based abatement technique for domestic
wastewater. Dalbergia sissoo and Cedrus deodara saw dust was used for the preparation of
activated carbons (ACs), using different activating agents (BaCl2, H3PO4, and H2SO4). The
efficiency and potential of developed ACs for Color, chemical oxygen demand (COD) and
biological oxygen demand (BOD) removal was investigated in batch mode experimentation.
Different operating parameters like contact time, COD and BOD load, pH and activated carbon
amount were also investigated. Statistical analysis showed that every AC is significantly diverse in
their potential for domestic wastewater treatment. Dalbergia sissoo based AC was most proficient;
reduced 87% COD, 87% BOD and 93% color. The results of this study can be utilized for the
establishment of large scale treatment plant. The quality of wastewaters after treatment was found
to be appropriate for direct discharge into streams for irrigation purpose. This experimentation
successfully addressed the local problem of wastewater pollution, using locally available
byproducts of furniture industry.

Dyes are the first noxious waste to be visually recognized, but one of the most difficult contagion to
remove because of their synthetic origin, recalcitrant and mainly complex conjugated aromatic
structure. So presented precise work is intended to look at the process of adsorption for the removal
of reactive azo dye using indigenous water chestnuts fruit and peels as a sorbent. A reactive Yellow
42 (RY 42) dye was taken as model azo based reactive dye. Comparative study of free,
immobilized anionic surfactant modified peels and fruit of water chestnuts revealed that sorbent
have higher sorption potential for RY 42 in free form as compared to immobilized and pretreated
form. Pretreatment and immobilization reduced the sorption potential of sorbent. Following trend in
sorption capacity (mgg-1
) was observed for RY 42 WCN F (30.77) > WCN F bead (25.66) > WCN
P (22.10) >WCN P bead (18.77) > SDS-WCN P(15.04) > SDS-WCN P bead(13.60) > SDS-WCN
F(11.66) > SDS-WCN F bead (10.70) > Plane bead(7.87) at optimized operating variables like pH
and dye concentration at 1.0 and 50 ppm. Equilibrium time was optimized at 60 min while it was
delayed for the beads up to 120 min. Pseudo-second order kinetic model ascertain that sorption of
dye over this indigenous adsorbent is governed by dye concentration and active sites over sorbent.
While applicability of Langmuir and Freundlich isothermal models over the equilibrium data
disclosed that sorption is monolayer and multilayer coverage of sorbate. Result obtained will be
statistically analyzed using regression line. Surface analysis of water chestnuts will be carried out
using SEM/EDX to determine the possible interaction between the dye and adsorbent. Need of
biological active agents focused on determination of Phenolic, Flavonoid and DPPH radical
scavenging activity of WCN P and WCN F. Results of assays show that higher TPC in WCN P
(143.62±0.01 mg/g) than WCN F (93.17 ±0.02 mg/g), while lower TFC contents in WCN F (35. 9
±0.01mg/g) than (21.9±0.1) WCN P. Maximum DPPH scavenging activity observed was 75.8±0.01
% and 22.9 ±0.04% for WCN P and WCN F respectively.

Soil pollution by persistent organic pollutants (POPs) is a major environmental issue. Pesticides
bearing hexachlorocyclohexanes (HCHs; α, β, γ and δ) and polycyclic aromatic hydrocarbons
(PAHs) were selected as target compounds in this study. Removal of POPs is widely studied due to
its importance in environment. In the present laboratory study, batch experiments were performed
for hydrocarbon degradation by using magnetite catalyzed Fenton–like (FL) and activated
persulfate (AP) oxidation. Soluble FeII was also used as a catalyst. Lindane contaminated soil was
originated from a pesticide dumping site. PAH degradation was studied in two soils originating
from coking plant sites at circumneutral pH. Organic analyses were performed by GC–MS and µ–
FTIR. Significant abatement of hydrocarbons (80-90%) was achieved in batch reactors after
chemical oxidation (FL and AP) while soluble FeII was unable to act as a catalyst for hydrocarbons.
No such differences were observed for lindane as both (soluble FeII and magnetite) were less
efficient at circumneutral pH. Soluble FeII was effective to degrade at acidic pH. No significant by–
products were observed during oxidation experiment underscoring the complete degradation of
hydrocarbons. No selective degradation was observed for FL with almost similar efficiency
towards all hydrocarbons. However, AP showed less reactivity towards higher molecular weight
PAHs. Among four HCHs, β–HCH was highly recalcitrant. Results of this study demonstrated
chemical oxidation can effectively degrade the persistent organic compounds. This study has
important implications for in-situ remediation of contaminated soils.

Cr(VI) is among one of the toxic metal detectable in earth crust. It is highly toxic to all the living
organisms due to its carcinogenic and mutagenic effects. Some microorganisms have ability to
reduce it into less toxic Cr(III) form efficiently. In order to study the contribution of microbes
towards Cr(VI) reduction an indigenous chromium-resistant bacterial strain A8 was isolated from a
tannery effluent. It was identified as, cellulosimicrobium sp. on the basis of morphological,
biochemical characterization and 16S rRNA gene sequencing. It could tolerate up to 1800µgml-1
of
K2CrO4 and showed optimum reduction (98.6%) of Cr(VI) at the conc. of 900µgml-1
at pH 7 and
incubation temperature of 37ºC aerobically. Cell-free enzyme assay exhibited the reduction of Cr
(VI) in-vitro. Four synthetic materials: sand, PVC, stone and rubber tubing were used as solid
support in order to evaluate the ability of the isolated chromium resistant bacterial strain for biofilm
formation. In column experiment among bacterial film coated materials, sand exhibited an excellent
Cr(VI) reduction (96%), PVC pipe and rubber tubing showed 94.5% and 90% reduction potential
of Cr(VI) respectively while minimum reduction potential of Cr(VI) was observed in case of stone
that was 88.4% after 96 hours of incubation. Fluorescent microscopy also revealed that bacterial
biofilm was distributed thoroughly on the surface of sand particles. Fourier transforms infrared
(FTIR) spectroscopy showed mainly the involvement of the glycerol units, polysaccharides and C-
N (alkyl) functional groups of isolated chromium resistant bacterial strain (A8) in the reduction of
Cr(VI).

To improve the stream water quality, different methods are employed which involve physical,
chemical and biological processes. Recently people use soil ball with effective microbes for stream
water quality improvement. However, the pH of these soil balls is acidic (pH 4.0) which are not
suitable for diverse microbes’ growth. As well the soil balls are not hard enough and quickly
dissociate under the stream water. In order to overcome this problem, various materials were added to
increase the strength as well pH of soil balls. As a result the hardness of soil balls as well pH 7.0 was
increased almost three folds in comparison with pH 4.0 of the soil balls. Additionally microbial
community was determined from soil ball’s whole metagenomic DNA using personal genome
machine (Ion Torrent). The raw data were analyzed through the MG-RAST server. The microbial
community of pH 4.0 sample was represented by 96.1% Bacteria, 2.7% Eukaryota, and 1% Archaea
while the pH 7.0 sample was represented by 67.7% Bacteria, 31.6% Eukaryota, and 0.2% Viruses.
Especially in comparison to pH 4.0 sample, the Eukaryotic community diversity increased highly in
pH 7.0 sample. These results suggest that our method is effective by increasing the stability of soil
balls as well change in community from prokaryotes to eukaryotes which may improve the stream
water quality.

1,2,3-Trichloropropane (TCP) is a toxic compound that has caused serious groundwater pollution at
chemical waste disposal sites. The availability of bacteria that can degrade this compound would
allow the development of bioreactors for TCP removal from contaminated groundwater. However,
many attempts to isolate such an organism by classical enrichments failed. A possible degradation
pathway would start with hydrolytic dehalogenation of TCP to 2,3-dichloro-1-propanol (DCP),
followed by further oxidative metabolism (Fig. 1). To obtain such an organism that degrades TCP,
we used an engineered haloalkane dehalogenase (DhaA31) with improved TCP degradation
activity. The enzyme was expressed constitutively under control of the dhlA promoter and
introduced into the genome of the DCP degrading bacterium Pseudomonas putida MC4 by using a
transposon delivery system. The transposon-located antibiotic marker was subsequently removed
using a resolvase step. Haloalkane dehalogenase was well expressed in the genetically engineered
bacterium MC4-5222 and was exported to the periplasm even though no signal sequence was
present. Growth of the engineered bacterium on TCP was indeed observed, and all organic chlorine
was released as inorganic chloride. The genetically engineered TCP-degrading strain is stable, free
of any additional plasmid-encoded antibiotic resistance marker and has the ability to completely
mineralize TCP with quantitative stoichiometric release of inorganic chloride. The application of
the strain in lab-scale bioreactors is under investigation.

Discharge of wastewaters loaded with azo dyes into natural streams and rivers poses a severe
problem, as dyes are toxic for aquatic life and are damaging the aesthetic nature of the
environment. Therefore, it is need of the hour to treat the dye loaded wastewaters before their
discharge. Because of being relatively environmental friendly, the use of biological techniques for
wastewater treatment has attracted worldwide attention. The present study was conducted to isolate
dye degrading bacterial strains from the wastewaters of diverse textile industries located in
Faisalabad. Initially, numerous strains were isolated and screened using liquid mineral salt medium
(MSM) enriched with reactive red S3R azo dye a as source of carbon. The most efficient isolate
M41 was selected to study the effect of different incubation and environmental conditions on the
decolorization activity. This isolate was found to show optimal decolorization activity at pH 8.5 in
the presence of yeast extract as an additional nutritional source under static conditions at 30 ˚C.

Biomass to be composted often consists of a very heterogeneous mixture of different materials such
as yard waste, sewage sludge, straw, food waste and other organic materials. Collection of
representative compost samples is therefore difficult especially under full-scale conditions. The key
problem is that of scale. The sample size (mass) used in for instance contaminant concentration
measurements is usually on the order of a few grams while the mass of a full scale compost pile is
on the order of hundreds of tons. The desired sample particle size is on the order of 1 mm while
particle sizes of the materials being composted under full-scale conditions is on the order of tens of
centimeters. This study was therefore conducted to develop and optimize a strategy for sampling in
compost and similar materials under full-scale conditions. The aim was to minimize the
measurement uncertainty with respect to material properties such as nutrient and contaminant
concentrations. Optimization was conducted considering multiple parameters such as the number of
turnings of the compost pile before sampling, the number of samples collected, the mass of each
sample, sample homogenization, particle size reduction, and the number of replicate measurements
conducted. Measurement uncertainty was evaluated based on measurements of water content,
inorganic matter content, and nutrient (N, P) content. Experiments were conducted using a 2k
factorial design. For each parameter measurement variability was determined as a function of
sampling strategy. These data were then used to identify the optimal sampling strategy. The optimal
strategy was then applied in organic contaminant concentration measurements and estimation of
measurement variability.

hexavalent chromium [Cr (VI)] is more toxic as compare to trivalent chromium [Cr (III)] because
of its comparatively higher solubility. It causes various detrimental effects on the plants by
affecting their physiological processes. Natures has gifted certain bacteria capable of degrading
these heavy metals and promote the plant growth under stressed conditions directly or indirectly by
lowering the ethylene level, producing certain harmones, improving the nutrient availability. In
chromium contaminated soil, plant growth can be improved by the reduction of Cr (VI) to Cr (III)
which is carried out by chromium reducing bacteria. So to evaluate the potential of bacteria for
growth promotion of okra in chromium contaminated soil and the transformation of Cr (VI) to Cr
(III), a pot experiment was conducted. Okra seed were inoculated with ten different bacterial
isolates capable of reducing hexavalent chromium and were sown in soil having 30.46 ppm initial
concentration of hexavalent chromium. Results showed that inoculation of bacterial isolates
significantly enhanced the growth and yield of okra, however, K-13 bacterial isolate was found to
be more efficient as compare to other isolates. This bacterial isolate had shown 77.5%, 72%, 2.5
fold, 2.9 and 4.4 fold, 1.4 and 2.5 fold, 3.9 and 6.5 fold increase in shoot length, root length,
number of pods per plant, fresh and dry weight of shoot, fresh and dry weight of fruit, fresh and dry
weight of root, respectively, as compared to un-inoculated control. This bacterial isolate was also
found to carry out maximum Cr (VI) reduction (69.7%). It was also observed that vegetative parts
retained more chromium as compare to reproductive parts. This study revealed that bacterial
isolates can be used as a tool for the remediation of heavy metal contaminated soil as well as to
improve the soil health which ultimately improves the plant growth.

Dyes are widely used in the textile industry to color the natural fibers. The toxicity of the dyes is of
considerable interest due to the ecotoxicological and environmental problems. Dyes cause major
diseases to human beings and animals. The electrochemical reduction of the dye has been
investigated in aqueous solution using an electrochemical cell, spectrophotometer and controlled
potential electrolysis (9.00 V). Optimum conditions for dye discoloration by controlled potential
electrolysis use an alkaline medium using cathodic stripping spectrophotometer. A linear
calibration graph was obtained using accumulation times of zero time, 2, 4, 6 and 8 minutes
respectively and an accumulation potential of 9.00 Volts. Electrochemical treatment showed to be
very efficient in removing dye’s color (Reactive Dyes) 90-99.3 %.

Air pollution has increased rapidly with no knowledge of its effects on agricultural crops in the
Northern region of Pakistan. The aim of this study was to assess the impact of hydrogen fluoride
(HF) on agricultural crops in Peshawar through field surveys. The HF concentrations from about
450 brick kilns around Peshawar, measured using passive samplers were higher in summer than in
winter in areas close to brick kiln fields. The mean summer concentration was 0.2μg HF m-3
, with
maximum of 0.3μg HF m-3
in May. Severe HF injuries to mango, apricot and plum leaves, in form
of necrotic leaf margins and tipburn, were found near the brick kiln fields. The fluoride content of
fruit leaves, wheat grains and spinach was significantly higher in the brick kiln area than at control
sites. It was also observed that the local community people were not aware of the toxic effects of
air pollution on crops. It was concluded that HF is s significant pollutant in Peshawar, especially for
summer crops and can change the climatic conditions for the local crops. Therefore, it is
recommended to conduct more detailed studies to determine the magnitude of damage caused by
HF in the Peshawar region and to educate people about this danger and alerting of the
consequences that can jeopardise their future food security.

Mung bean (Vigna radiata, MN-98) grown in pots and exposed to ambient air at a field-site in
Peshawar (Northern Pakistan) was subjected to EDU (ethylene diurea) to assess ozone effects on
the yield and quality of this important legume. The experiment – the first of its kind in Northern
Pakistan - was carried out according to a standardised protocol from March to June, 2011.
Temperature and relative humidity were recorded half-hourly and ozone was measured using
passive samplers (double-sampling, four-weekly time steps). Weekly foliar injury assessments were
conducted, followed by a final harvest on day 84 of the experiment. The total biomass, seed weight,
no. of pods, length of pods and roots were recorded. Passive samplers results revealed that the
mean ozone concentration was significantly lower (24.2ppb) in March and April as compared to
May and June (49ppb). Leaf marginal necrosis were recorded in both EDU and non-EDU treated
plants in May and June that might be due to severe exposure to direct sunlight. No ozone visible
injury was reported during the entire experiment. However, the number and biomass of pods were
significantly reduced in non-EDU treated plants as compared to EDU treated plants. The biomass
of shoots, leaves and the root length increased significantly in EDU treated plants. Seed weight was
significantly reduced (20%) in non-EDU treated plants. The overall plant biomass was significantly
higher (30 %) in EDU treated as compared to non-EDU treated plants. It was concluded that a)
there was a close positive relationship between the ozone concentration and temperature and b)
ozone is a threat to local summer legumes grown in Pakistan, with potentially negative impacts on
food security in the region.

Present study was carried out to assess effects of hydrogen fluoride (HF) on locally important
vegetables grown around the brick-kilns of Muzaffargarh (Southern Punjab, Pakistan). For this
purpose, vegetables were grouped into four categories i.e., root-vegetables, inflorescence-
vegetables, fruit-vegetables and leafy-vegetables. This study was carried out site-wise and transect-
wise from the brick-kilns in order to highlight the significance of the wind direction that usually
carries atmospheric pollutants beyond the regional and local boundaries. Fluoride concentrations
were found in nearly all vegetables in statistically significant quantities and were mostly higher
than the prescribed HF limits set by the World Health Organization and Air Quality Standards
(2006). It is worth noting that leafy and fruit vegetables were more sensitive than other ones, and
accumulation of fluoride decreased when moving away from the brick-kilns. It was concluded from
this preliminary study that atmospheric HF was definitely accumulated in the nearby vegetation of
brick-kilns above threshold concentrations and if these plants/plant parts are consumed by
humans/animals can cause serious illnesses leading to cancer as well.

The prevalence of sulfidic sediments in inland wetlands has been only recently recognised in many
parts of the world. The exposure of sulfidic sediments in these wetlands due to natural and human
induced drying events has resulted in the oxidation of iron sulfide minerals, the formation of
secondary iron minerals characteristic of acid sulfate soils (ASS) and the release of highly acidic
solutions. The objective of this study was to determine the mineralogy and morphology of
sediments collected from the oxidised surface horizon (0−5 cm) of an inland acid sulfate soil
located in south-western New South Wales (NSW), Australia. Random powder X-ray diffraction
(XRD), transmission electron microscopy (TEM) and scanning transmission electron microscopy
combined with energy dispersive X-ray spectroscopy (STEM-EDS) techniques were used to
characterise the minerals present in these sediments. Akaganéite was identified as the major
mineral phase in the sediments; K-jarosite was also determined in small amounts in some
sediments. The minor amounts of jarosite formed at the study site are predicted to be a product of
transformation of previously precipitated akaganéite. The XRD patterns of sequentially washed (E-
pure® water-0.01 M HCl-0.01 M EDTA) sediment samples showed all akaganéite peaks; the
Rietveld refinement of these patterns also revealed a predominance of akaganéite. The chemical
analyses of the original and washed sediments using STEM-EDS clearly showed the presence of
akaganéite as a pure mineral phase with an average Fe/Cl mole ratio of 6.7 and a structural formula
of Fe8O8(OH)6.8(Cl)1.2. These findings show that the extreme saline-acidic solutions (pH ~ 2, EC =
216 dS/m) at the Bottle Bend lagoon provide ideal conditions for the crystallization of this rarely
forming mineral. The formation of secondary iron minerals (such as akaganéite) is of particular
significance due to their high reactive surface areas and their ability to affect the mobility and
bioavailability of metals in the environment through adsorption and coprecipitation processes.

One of the important sources of airborne particulate matter is fuel burning. Plant matter, or
biomass, has served as one of the primary energy forms utilized by humans for essential activities.
The knowledge about the contribution of different sources to atmospheric aerosols is of great
importance. Analysis of the tracer molecules from organic aerosol is helpful in determining the
contribution of different sources to atmospheric aerosols. Levoglucosan and other anhydro-sugars
are believed to be important tracers produced from pyrolysis of cellulosic part of wood while lignin
pyrolysis yields various characteristic compounds like phenols, aldehyde, ketones, carboxylic acids
and alcohols, for which structure can be traced back to the lignin characteristic monomers. Syringic
Acid, Vanillic acid and 4-hydroxybenzoic acid are some aromatic acids with OCH3 and OH
substituent on phenyl ring that have been found in biomass burning smoke in various studies. In
present study we analyzed biomass-burning tracers in aerosol samples collected from southern part
of Sweden. Sampling was carried out for complete one year on weekly basis. Samples were
extracted using dichloromethane and methanol mixture with ultrasonic assistance. Concentrated
extracts were derivatized with N,O-bis(trimethylsilyl)trifluoroacetamide (BSTFA) containing 1 %
trimethylsilyl chloride. Analysis for biomass burning tracers, levoglucosan, mannosan, glactosan,
syringic acid, vanillic acid, and salicylic acid was done using gas chromatography mass
spectrometry (GC-MS). Levoglucosan concentration was found in a range of 2 – 153 (average
46.7) ng.m-3
, for mannosan, it was 0.3 – 14.8 (average 4) ng.m-3
, and for glactosan, it was 0.3 –
19.3 (average 5.2) ng.m-3
. Individual concentrations of vanillic acid, syringic acid and salicylic acid
were found below 3 ng.m-3
. Mannosan was found 2.2 – 19.5 % with an average 9.9 % of
levoglucosan concentration. While glactosan concentration was 5.1 – 19.4 % with an average of
11.6 % of levoglucosan. Levoglucosan was found to account for 0.12 – 14.1 % of OC with an
average of 3.6 %. Collective contribution of syringic acid, vanillic acid and salicylic acid to OC
was less than 0.5 %. All the tracers analysed, shown an increasing trend in the concentration during
winter times and a good correlation was found among them.

In this paper we are analysing the effect of Weather Research and Forecasting (WRF) land surface
schemes (LSMs) on weather simulation in Delhi region. The widely used WRF model provides a
few land surface schemes (LSMs) to compute heat and moisture fluxes over land surface. The
LSMs differ in complexity and approaches used. In order to assess their role on weather
simulations in the Delhi region, we performed WRF simulations for 30 km resolution domains over
the Delhi region. We used the four LSMs provided with WRF: 6-layer Rapid Update Cycle (RUC),
5-layer thermal diffusion, 2-layer Pleim-Xiu scheme (together with the Pleim-Xiu surface layer and
the ACM boundary layer models), and 4-layer Noah scheme. We focused on summers of 2009. The
RUC scheme showed stronger-wind, warmer, and drier biases. The Pleim-Xiu scheme is giving
best result for the temperature and Wind Speed. Thermal Scheme is giving best results for Relative
humidity. So we can say that if we compare only LSP’s by keeping other schemes same then Pleim
is the scheme which is giving best results for Temperature (Cumulative PDF - Pleim Xiu Scheme
error < 3 degree is approx. 60%) and Wind Speed. Thermal Scheme is giving good results for
Relative Humidity. Weather underground provides local & long range Weather Forecast, weather
reports, maps & tropical weather conditions for locations worldwide. The simulation results are
compared to the weather Underground measurement data.

Integration of priming effect (PE) in agroecosystem models is central challenge to predict
consequences of global change on ecosystem carbon (C) fluxes and feedback on climate, and to
design new agricultural practices with minimum use of fertilizers. PE corresponds to the
acceleration of mineralization of recalcitrant soil organic matter (SOM) after addition of fresh
organic matter (FOM) to soil that leads to the stimulation of soil microbes. Over the last decade
many models were built to simulate PE. However, PE has never been inserted in plant-soil model to
analyze its consequences on ecosystem properties. The objective of this work is to build a simple
model of soil organic matter (SOM) dynamics by taking into account PE, soil-plant relations and
plant-microbial interactions. Our approach is to integrate the plant in the model of Fontaine and
Barot (2005) and to analyze it mathematically at equilibrium followed by numerical simulations.
Taking together, our results suggest that PE is the necessary universal mechanism through which
nutrients are shared between plant and micro-organisms via a bank mechanism. In a permanent
vegetation cover, this mechanism helps to synchronize the availability of soluble nutrients to plant
requirements during temporal fluctuations and the existence of decomposers in their limitations by
C or a limiting mineral nutrient. Our results can allow designing highly-efficient food production
system that will minimize nutrient losses (leaching and denitrification) and fertilizer application
while leading to long-term SOM accumulation.

Warm and dry climate caused by anthropogenic climatic changes may alter plant biochemical
composition and ultimately its decomposition behavior in soil. The objective of this study was to
investigate the effects of future warming and summer drought on the biochemical composition of
aerial litter from forage plants and the potential mineralization of this modified material in soil. Our
conceptual approach was based on the sampling of aerial forage plant litter of two grassland species
(Festuca arundinacea and Dactylis glomerata) at the end of spring and in summer. Moreover, we
sampled plant material exposed to elevated temperature by infrared heating of the canopy (+6°C)
during summer. We analyzed for elemental and stable carbon isotope composition of this material
as well as lignin and non-cellulosic neutral carbohydrate contents. The mineralization potential of
the forage litter in soil was evaluated under optimum laboratory conditions. Additionally, we
examined their effect on the potential mineralization of native soil organic matter (SOM). Drought
stress significantly changed the elemental and isotopic composition of both plant species with
increased N contents and lower C/N ratio. The δ13
C values also clearly indicated consistent
variations in stomatal conductance during the dry summer period. This increased N contents and
lower C/N ratio resulted in higher mineralization of drought affected plant material. In contrast,
there was no significant of heating on plant elemental and isotopic compositions, while plant
biochemical composition changed under elevated temperature. Priming effects of plant material
subjected to climatic stresses seems to be governed by alterations in plant chemical composition
rather than stoichiometry. So, different mineralization rates of plant materials produced under
different climatic conditions might indicate their altered trends towards carbon sequestration in soil.

modeling approach is to evaluate climate change patterns by analyzing time series data of climate
extremes (minimum and maximum temperatures) data. Thirty years (1981-2010) of climate
extremes data were collected from five representative cities across Punjab, i.e., Multan,
Bahawalnagar, Faisalabad, Sargodha, and Rawalpindi, Thirteen temperature indices, established by
the Expert Team on Climate Change Detection, Monitoring and Indices (ETCCDMI), were
calculated using above data and RClimDex software. Mann-Kendall Test and Sen's Slope Estimates
were used to detect rare, general, and prevailing climate trends. The results indicated consistent
patterns of global warming over most of the province. Overall, extremely warm events have
increased and the extremely cold temperature events have decreased for the analysis period. Cool
nights have significantly decreased and hot nights have significantly increased. All the cities
experienced the most number of cold spells during 1984. Regionally averaged per decade summer
days (when temperature was > 25oC) and tropical nights (when temperature was > 20
oC) were
computed to increase by 5 and 8, respectively.

Nitrogen deposition may modify the effects of increasing tropospheric ozone on plant communities.
Our evidence suggests that negative responses to ozone are exacerbated under conditions of high N
availability. This highlights the importance of considering interactions between pollutants in the
evaluation of critical levels (or loads) for semi-natural ecosystems. During the last century,
concentrations of ozone (O3) in the troposphere have risen considerably as a result of anthropogenic
activities. O3 is an important phytotoxic air pollutant, with current ambient concentrations high
enough to cause visible O3 injury and detrimental effects on plant growth in many parts of the
world. Some evidence exists to suggest that environmental factors such as soil fertility and nitrogen
deposition may influence plant sensitivity to O3. An experiment was, therefore, established to
examine the effects of these two global change issues, in combination. Two plant species Trifolium
repens and Festuca ovina were exposed to O3 under differing levels of N addition to address the
question of how soil resource availability (nitrogen status) affects plant response to O3 in a grass-
legume mixture. Mixed species pots were exposed to ozone in a series of 16 open top chambers at
Silwood Park (Ascot) for a period of 16 weeks. Ozone exposure was carried out from 9am-6pm
daily, with target concentrations of 0 ppb, 30 ppb, 60 ppb and 90 ppb (resulting in seasonal AOT40
values from 0 – 25,492 ppb.h). In addition, weekly applications of Hoagland’s solution with
nitrogen levels equivalent to 0 or 50 kg N ha-1
were given to pairs of pots over the course of the
experiment. Plant performance was monitored during the exposure period, after which
aboveground plant material was harvested, separated into living, senescent or dead material and
then oven dried and weighed. Below ground biomass was also measured, following root washing.
Results show a negative effect of O3 and N on above-ground biomass of T. repens and positive
effects of both pollutants on the biomass of F. ovina. Aboveground biomass reductions of 80.6%
(HO3+N) and 70% (HO3-N) for T. repens indicate greater effects of ozone in high N treatments.
Below-ground biomass also showed a significant decrease in ozone treatments (44.6%, HighO3+N
and 35.8% HighO3-N) compared with filtered air. Overall, results suggest that N deposition may
exacerbate the effects of O3 on legumes, driving changes in plant productivity and community
composition.

Due to climate change and global warming, frozen water resources have been losing their mass at an
unprecedented rate, not only, reducing the ice and glacier mass but increasing the number and extent of glacial
lakes.. The global warming can have a strong impact on river flows in Pakistan. This may be due to the melting of
snow and glaciers at a higher rate and changes in precipitation patterns. Now snow occurs in late winter and
disappears in early summer, hence, reducing the residency period to complete metamorphic processes for
conversion into ice and glacier. Snow and glacier volume and snow covered area decreasing day by day due to
climate change. Glaciers are quit sensitive to climate change therefore, the studies and monitoring of glacier has
gained importance and a lot of work has been conducted all over the world during recent years. As a case study
climate change impact assessment on glacier melting were studies at Mangla catchment area using the
advancement of remote sensing and GIS. Due to periodic Revisits of satellites over the area of interest, it is now
convenient to monitor the snow cover at regular intervals. Moderate-Resolution Imaging Spectroradiometer
(MODIS) is a reliable sensor, due to its spatial, temporal and radiometric resolution. In addition elevation data
from Shuttle Radar Topographic Mission (SRTM) is used for the production of Digital Elevation Model (DEM).
The temporal snow cover is derived from Normalized Difference Snow Index (NDSI). Temperature data of
various years is being used to identify the impact of climate variability on snow cover. Temporal analysis of snow
cover using spatial analysis tools revealed variations in snow cover of the study area during different year 2000 to
2011 data. The results of present study show good agreement between temperature change and snow and glacier
melting. As global warming increase frozen reservoirs of waters are decreasing.

Flooding is a serious, devastating, and catastrophic hazard that many countries face regularly. During 2010,
uplifting of monsoon, trade winds, to higher altitudes caused 34 days fuel recharge from Arabian sea which
resulted in intense rainfall after condensation. Justified reason was synergistic effect of uplifting of monsoon and
blocking event in jet stream. In the second half of July, Blocking Even froze the meander of Jet stream over
Europe and Asia. Extreme rainfall occurred in Upper Asia and catastrophic flooding was reported in south Asia.
Uplifting of Monsoon with moisture content was continued upto this period (app. 34 days) and more and more
trade winds came from Indian Ocean. In the start of July, 2010, changes in monsoon pattern caused the most
severe flooding in Pakistan’s history. It has been estimated that, by using flood simulation and GIS overlays
technique with original waterways, changes in monsoon pattern caused one fifth of the country to be inundated.
Flooding remained continued in late July and rainwater from the highlands enters into major rivers which affected
nearby areas of Indus River. In the late July, In the late July, calamity was observed in major areas of Sindh. Heavy
monsoon rains affected one fifth of total area of Pakistan which was inundated and rest of was in danger. In early
August, flood waters began to recede in the southern provinces. Level of water in the Indus River continued to rise
more and more, however, as it travelled southward, flooding in eight districts of Punjab and thousands of communities
along Indus River occurred. More than 250 mm of rain fell over a 36-hour period. Abeyant policies by PID caused
destruction in Jacobabad which was not normal Indus waterway. Finally, the first week of August became worst week
of extreme flooding and land sliding in Pakistan. However, these floods were big source of hydel energy from which
energy plan of Pakistan can be ameliorated if simulation was taken on time. Simulation analysis explains that such
climate changes are very often in future as well which may help to meet energy crisis as well as water deterioration.
Associated reasons behind these floods were monsoon winds moved to higher altitude caused more fuel recharge
from Arabian Sea and integrated unusual holding patterns in the jet stream caused weather systems stopped, violation
of Indus Water Treaty 1960, and heightening Monsoon activity by the la Niña phenomenon in the Pacific Ocean.

In this study, we test the high resolution satellite rainfall product (CMORPH) (Joyce et al., 2004)
for rainfall-runoff modeling. The study area is the Gilgil Abbey catchment, Ethiopia that has
relatively low density of rain gauge stations. For rainfall-runoff modeling, we selected the lumped
conceptual, water balance based HBV model (Lindström et al., 1997). The study aims to assess
how model parameter uncertainty is affected when gauged rainfall model input is replaced by
satellite based rainfall estimates. For uncertainty assessments, we rely on a multi-objective
optimization framework. The specific objectives of this research are (i) to evaluate accuracy of the
CMORPH rainfall product (ii) to evaluate HBV model performance for a) gauged rainfall input
data, b) CMORPH input data and c) bias corrected CMORPH input data and (iii) to assess model
parameter uncertainty for these three cases. For parameter uncertainty assessment, we selected the
Multi ALgorithm Genetically Adaptive Method (AMALGAM) for multi-objective optimization
(Vrugt and Robinson, 2007). This algorithm incorporates the attributes of several optimization
algorithms and gives reliable and efficient solution to multi-objective optimization problems
(Zhang et al., 2009). Model performance is assessed by Nash-Sutcliffe coefficient (NS) (Nash and
Sutcliffe, 1970), Relative Volumetric Error (RVE) and a weighted combination of NSE and RVE
objective functions. Results of this study help to better understand the efficiency and application of
CMORPH rainfall products for rainfall-runoff modeling and water resources assessments in

The materialization of Remote Sensing and GIS technologies has substantially eased the problems of groundwater.
Groundwater is a key resource for global agricultural production but is vulnerable to a changing climate. Proper
utilization of these can provide more vital information in managing such inadequate resource. GIS can help to
integrate, analyze and represent spatial information and database of any resource, which could be easily used for
planning of resource development, environmental protection and scientific researches and investigations. A
preliminary assessment of vulnerability to groundwater contamination in Lahore district was undertaken to assess
the impact on groundwater. The Information on the hydraulic confinement, overlying strata in terms of their depth
of water, net recharge, aquifer media, soil media, topography and hydraulic conductivity was incorporated into the
DRASTIC model, to produce groundwater vulnerability maps. GIS was used for indexing and overlaying the
different data sources to create a groundwater vulnerability map. The integration of such groundwater features of
different periods and their analysis with structural features provided some newer information on geo-system
processes and their interface dynamics with hydro-systems, from which, certain strategies were suggested for
better groundwater management.

Over the last two decades, dengue fever has become a major mosquito borne disease in Pakistan. Dengue
outbreaks were reported in the major cities of Pakistan especially in Lahore where the number of dengue cases
increases radically in 2011 making it the worst epidemic disease in the national history. This situation has emerged
as a serious threat to public health and managing and controlling risks of dengue outbreaks are being given a
serious consideration by the concerned local and provincial departments. It has been observed that dengue virus
grows in specific climatic conditions and there are some environmental factors (EFs) that promote its growth. The
objective of this paper is to propose an advance approach to identify the risk prone areas by linking these factors
with dengue outbreaks using satellite data and Geographical Information System (GIS) techniques. The Remote
Sensing (RS) and GIS techniques used in this study are proven to be more efficient and cost effective as compared
to the traditional approaches. Information provided in terms of spatial and temporal distribution patterns of dengue
fever outbreaks in Lahore and its relationships with EFs are helpful in developing dengue risk maps. Assessment
of dengue risk maps based on EFs, investigates the dengue risk prone areas of Lahore. These maps will help
concerned departments in managing dengue outbreaks in a more informed and effective manner. The EFs used for
this study are Land Surface Temperature (LST), Normalized Difference Vegetation Index (NDVI), precipitation,
air temperature and humidity. The results show that most of the cases occurred in residential areas near hospitals
and those areas that have received heavy rainfall followed by high NDVI and high temperatures.

Climate change is a present day reality and the developing countries like Pakistan are most at risk.
Warming of our climate system is beyond any doubt and unambiguous as concluded in the Fourth
Assessment Report (AR4) by the Intergovernmental Panel on Climate Change (IPCC) in 2007.
Over the last one hundred years (1905-2006), the world has warmed up by three-quarters of a
degree Celsius. Human are exposed to climate change directly through the weather patterns and
indirectly through changes in air, water, food, ecosystems, agriculture, livelihoods and
infrastructure. The IPCC has warned and anticipated widespread increase in extreme precipitation
with greater risks of flooding owing to intense precipitation over Pakistan. Pakistan is highly
vulnerable to adverse vagaries of climate change. Mitigation and adaptation to climate change has
turned out to be the key priority issue for the country particularly for urban areas as the cities are
more vulnerable due to a high concentration of population and economic activities in a relatively
small space. This demands capacity building of cities to develop and implement adaptation
measures. Population and infrastructure in the far and wide of Pakistan will be particularly
vulnerable to flooding from extreme precipitation. Poor planning has contributed to a reduction of
the resilience of ecosystem services on which populace depends. Climate change will make life in
the cities more and more miserable, unless measures for adaptation and control of environmental
degradation are taken immediately. It is pertinent to assess the capacity of city’s infrastructure and
services to cope with climate change and climate related disasters as the situation would lead to
social issues such as migration, competition and conflicts. The ultimate objective of adaptation is to
decrease the vulnerability of ecosystems and societies. There is need for systematic sector-based
work where climate-related issues typically include disciplines, sectors and administrative regions
and, therefore, cannot be dealt with within single sectors or organizations. Hence dedicated efforts
are needed to bridge the gaps between sectoral organizations, in order to share relevant information
concerning risks and their management as well as achieve efficiencies and synergies. This study
suggests and arrives at climate mitigation and adaptation strategies in context of current climate
change scenario in Pakistan and more importantly the adaptation strategies for sustainable
agricultural practices based on a participative vulnerability assessment and identification of
adaptation measures that aim to provide valuable insights to policy makers, urban planners, local
governmental organization and stakeholders. To meet the challenges of climate change in Pakistan,
the planning process should comprise of the following steps: (1) identify current and future climate
changes as accurately as possible; (2) assess the vulnerabilities and risks especially the poor
communities; (3) develop an adaptation strategy using risk based prioritization schemes; (4)
identify opportunities for co-benefits and synergies across sectors; and (5) adaptation options to be
identified based on past experience and extensive public and expert consultations.

Seabuckthorn (SBT) plays an important role in the sustainable development and eco-preservation
of high altitude/cold desert areas. SBT is nature’s bio factory, having >200 bioactive components,
32 types of fatty acids, 36 types of flavonoides and phenols and 24 kinds of minerals and trace
elements. It has huge potential for conversion into health foods and medicines. Important bio-
molecules include the vitamins, organic acids; flavonoides, phenols; carotenoides; sterols; betaine;
5-Hydroxytryptamine (5-HT); coumarin and ursolic acid etc. More than 90 % total fatty acids are
essential viz Omega 3, Omega 6 and Omega 9. Role of SBT as Neuroprotective, Hepatoprotective,
Cardio protective, Radio protective, Anti inflammatory, Anti oxidant, Anti microbial, Anti
Ulcerative, Immunomodulator and even as anti diabetic has been reported. A number of products
having health, medicinal and cosmetic benefits can be developed from SBT fruits and leaves
through value addition. Enhancing SBT resource through cultivation will go a long way in
economic development of cold desert areas. India and Pakistan have 11500 and 5000 ha area under
wild SBT resource respectively. Only a few plant species can survive in cold desert areas due to
adverse climatic conditions. Soil and water erosion are major problems of hilly mountains. SBT can
effectively prevent soil erosion and surface run-off, since it has an extensive root system which
helps it in tolerating moisture stress and protects it from strong winds. That is why SBT is an ideal
plant for flood protection on river banks or checking the streams, wasteland development, sand
dune fixation and control of soil erosion through wind and water. Seabuckthorn roots contain
nodules which are produced by symbiotic mycorrhizal fungus–Frankia, which help in nitrogen
fixation and improvement in soil fertility. Siltation process of rivers is likely to be reduced
substantially with SBT plantation through prevention of land slides. This plant could be propagated
near all the major rivers in the Himalayas, so that the Himalayan eco-system will be protected. SBT
is not just a plant with nutritional, health and medicinal properties; it also has great economic value,
besides providing significant environmental benefits in many countries e.g. to combat
desertification and preventing soil erosion in China; to improve soil quality in Germany; to reclaim
wastelands in Poland and to enhance wildlife habitats in Canada etc. SBT plants help the flora and
fauna by providing adequate food, thermal cover, protection, nesting site for songbirds and
excellent escape cover for upland game birds. Once established, SBT propagates very fast on its
own through suckers. Mixed farming of SBT with maize, potato and fruit trees can result in an
increased yield of revenue. Residues of fruit, pulp and leaves could be used as an excellent source
of fodder for cattle. It will also enhance employment opportunities and sustainable development of
cold desert areas through its cultivation in waste lands without much investment. Development and
commercialization of Leh Berry Juice has laid the foundation of a sustainable SBT industry in
India. The revenue generated from value added products of SBT can ensure a good quality of life to
the people of these cold desert areas on sustainable basis.

Community forestry management practice is recognized as important climate change adaptation
and potential mitigation strategy, by climate change policy and National Adaptation Programme of
Action (NAPA) in Nepal. Based on the paper presenter’s 10 years long experience in the issues and
the study of six community forest user groups, three from each of DFID/UK and CARE supported
groups, the finding shows that the practice is initiated and groups are formed to address the issues
of natural hazards and mal-adaptation practices the local people followed previously both in
responses to changes in local forest ecosystem and to socio-economic condition due to climate
change. The practices of forest management not only increase the adaptation of forest through
restoration of forest ecosystem, but also is suitable mechanism for planned, decentralized, cost
effective, linked and inclusive adaptation strategies to poor and marginalized member of the
groups. However, the people who are member of the groups have opportunity to get benefit from
the benefit of management including adaptation fund while there are some households/communities
are excluded from the groups. Also, limitation on extraction of forest products is in some instances
undermining the livelihoods strategies of the forest dependant people limiting their adaptation
capacity. There are also issues of resource access with members in particular can be constrained by
poorly aligned jurisdiction. Simultaneously, the community forestry management promotes entry
points for pro-poor mitigation strategies. The growing stock of forest particularly in hills increased
and the community forestry user groups have established resource distribution system based on
wealth ranking of the groups, the mitigation strategies specifically the REDD mechanism may
benefit to the poor category of the users. However, we find that the executive committees of
CFUGs are politicized and the political ideology affects resource distribution. Also, there are high
value forest trees, the illegal sale of which offers considerable financial intensives. So, particularly
in the Terai, the conservation and management of forest may be competing with very high
opportunity costs. Also, there are significant issues of land tenure conflicts between people and
Government, VDCs (Village Development Committee), and communities, the result of which does
not favor the protection, management and conservation of forest. The findings suggest that climate change friendly approach needs to integrate in the policy of constitutions and operational plan preparation process of community forest management. As the groups are growing as a local adaption funding institutions, the role of CFUGs should also be linked with sources of credit and low-interest loans. In addition, to increase the community forest for mitigation, climate change sensitive forest management guidelines needs to developed and linked with national forestry activities.

The urban population in India is presently about 27.8% of the total population (Census of India,
2001) and is expected to reach 50% by 2050 at the present growth rate. This number would be 820
million by 2050 (Agrawal, C.S., Mittal, S., Goyal, H., 2000), which would further aggravate the
currently strained water resources in the urban areas. There is a rapid increase in demand of water
supply which has resulted in increase in wastewater and untreated sewage (The National
Commission On Urbanisation, 1988). The wastewater, disposal has resulted in many environmental
problems such as the contamination and pollution of ground water, pollution of water bodies etc.
the situation is particularly very grim in small and medium towns (Central Pollution Control Board,
2001). In this paper case study of Patiala city has been undertaken to review and analyze the effects
of disposal of untreated wastewater on the urban stream and ground water quality. This paper gives
categorical analysis of present scenario and various technologies available for restoring the water
quality of urban streams and ground water. A comparison has been made between the centralized
wastewater treatment system (CTS) and decentralized wastewater treatment system (DTS) on the
quality of water disposed off in the streams and their respective economic viability in different

Environmental pollution and presence of underground hard water is causing unavailability of safe
drinking water in Pakistan. Groundwater is the main resource of drinking, irrigation and industrial
use. Groundwater is charged by surface water, precipitation, or the storm water through infiltration.
The industrial waste-water and municipal sewerage containing bacteria of E.Coli, Cholera, and
parasites of Giardia is directly disposed off into the canals and streams, which consequently are
absorbed into the soil and contaminate the groundwater. Infiltration water also dissolves the
hardness forming minerals present in the soil and makes the groundwater hard. Water table is
usually very low in arid areas. To manage the groundwater quality and water table depth, author
has devised a mechanism to recharge the groundwater resource in a way that the rooftop rainwater
and the storm water after filtration and oxidation is directly channeled to the water table via
plurality of pipes or cemented dug bores. This recharge reaches water table without mixing with the
polluted surface water or hardness forming minerals present in the soil. Such kind of large scale
rechargers, if installed in open ground to collect storm water, and low cost mini rechargers installed
in buildings to collect rooftop rain water and to recharge the aquifer, the groundwater quality of the
town will improve gradually. This system of artificial recharge can also help to raise the water table
resulting in the reduction of pumping costs. Author holds the patent rights of the invention, patent #

Atmospheric aerosols or particulate matter (PM) have become of vital importance since two
decades due to their role in ambient air quality, climate change and adverse health effects. The
atmospheric pollution and extreme weather events have become a serious problem in developing
countries like Pakistan. Carbonaceous species makes large fraction of the atmospheric aerosol
which plays an important role in the atmospheric chemistry, radiative transfer and health effects.
Carbonaceous species mainly consist of elemental carbon/black carbon (EC / BC) and organic
carbon (OC). In this study an attempt was made to study the chemical composition of particulate
matter, their possible sources, and the contribution of wood smoke particles to organic carbon (OC)
and particulate matter (PM) in Islamabad during winter time (December 2007) and in Karachi
during pre moon soon period (March - April 2009). The PM concentrations in Karachi were
ranged between 42µg/m3 and 120µg/m
3 (mean 75.21µg/m
3) for PM2.5 and from 255 and 792
µg/m3 (mean 437µg/m
3) for PM10. The levoglucosan concentration is found to be in the range
52ng/m3
– 185ng/m3
(average 99ng/m3) and 91ng/m
3 – 398ng/m
3 (average 210ng/m
3) for PM2.5
and PM10, respectively. While in case of Islamabad the concentration of TSP varied from
218.9µg/m3 to 468µg/m
3 (mean 343µg/m
3) and PM10 Concentrations were in the range of 89.73 -
304.82 µg/m3 (mean 194 µg/m
3). Contribution of biomass burning to PM was calculated using
levoglucosan as a tracer. In Karachi, the biomass smoke OC constitute 5 - 25% of PM-OC in both
fractions however biomass contribution to total PM mass was found to be 2 - 8 %. In case of
Islamabad wood smoke contributes 9 – 13% of total PM mass in TSP and 16 – 22% in PM10. A
good correlation were observed between PM10, TSP and Ca++
which implies that mineral / road
dust may be major contributor to PM in Islamabad. Sea salt contribution was calculated using water
soluble Na as tracer and 3 - 15% contribution of sea salt to total PM mass.

Rhizoremediation is an emerging technology for remediating organic pollutants such as
pentachlorophenol (PCP) in soils. Wetland plants like rice contain aerenchyma tissue, which
channel air transports from the leaves to the roots, and uniquely develop aerobic-anaerobic
interfaces in the rhizosphere. To investigate the rice rhizosphere effects on the dynamic changes of
various extractable fractions of PCP and the microbial community, a glasshouse experiment was
conducted by using a rhizobox in which rice seedlings were grown for 45 days. The soil was spiked
with 20 and 45mg kg-1 PCP. Soil in the rhizobox was divided into five compartments at various
distances from the roots. Sequential PCP extractions were conducted with three extractants: CaCl2
(0.01molL-1), butanol (99%), and DCM (99%). Butanol extractable form of PCP showed a
significant difference in the rhizosphere at 3mm distance from the roots at both PCP levels. Thirty
four phospholipid fatty acids (PLFAs)in the rice rhizosphere were identified in soils given the two
different PCP concentrations. The total soil PLFAs concentration in the planted soils ranged from
29 to 52 nmol g-1. The highest concentration of PLFAs was at 3 mm distance from the roots at both
PCP concentrations. The results suggest that the aerobic-anaerobic interface established by the root
in the rhizosphere of rice increases PCP dissipation in the rice rhizosphere.

Lead (Pb (II)) binding capacity by a natural and low cost agro waste adsorbent Citrus sinensis peels
(CSP) in original, chemically (surfactant, acid, organic solvents) and physically pretreated
immobilized (PVA-Na alginate, Na alginate) form was carried out. Batch adsorption experiments
demonstrated that the rate of Pb (II) sorption increases fastly initially, reaching up to maximum
sorption capacity of 88 mgg-1
after that it attains equilibrium with in 60 min at the pH of 4.5 with
optimized dose of 0.1 g having particle size of 0.71 mm. Kinetic data were successfully described
by a pseudo-second-order model revealing that adsorption is rate controlled. Applicability of
Langmuir isotherm on adsorption data indicated the monolayer coverage of the sorbate. These
results inferred that pretreatment and immobilization reduced the sorption tendency from 88 mgg-1
-
23mgg-1
. Regeneration of metal was attained up to 80 % using EDTA as eluting agent. CSP being a
cheap, highly selective and easily regeneratable biomass seems to be a promising substrate to
entrap Pb (II) ions in aqueous solutions.

The release of unloaded azodyes by textile and other industries in neighboring water bodies causes
severe water pollution. The use of this azodyes contaminated wastewater for crop production has
been increased alarmingly in surrounding areas of these industries allowing the dangerous azodyes
and their metabolites to enter our food chain. The application of algae for phycoremediation of
textile wastewater and its reuse as irrigation is a feasible option. Therefore this study discusses
current knowledge regarding wastewater treatment using algae isolated from fresh and salt water
bodies. In addition, the phycoremediated wastewater application to crop plants not only removes
the threat of hazardous materials to enter our food chain but also employ the reuse ability of textile
wastewater and obtaining better crop production. Overall, the algal use not only helps in treating
the contaminated wastewaters and makes them reusable again for plants but also produce biomass
which could be used for biodiesel production.

the iron manufacturing units are working under small sheds and 90 to 95 % iron furniture prepared
by unregistered small scale industries. Focused group discussions (FGD) have been conducted
among IFMU workers which are based on a cross sectional, descriptive, analytic and time limited
study. Workers are assessed for exposure to occupational and environmental risks, the use of
protective equipment and health complaints by interviews. All workers of the area have been taken
as study population and by method of random sampling all the units have been sampled with the
help of self designed questionnaire and use of direct reading instruments. The data is arranged in
tabulated form and the tables show the frequency distribution of variables among the workers. The
data is divided into three parts: occupational accidents profile, safety measures profile and
monitoring of work environment. There is a high level (>90%) exposure to either dust, fumes, noise
or heat and there is less reported use of personal protective equipment. The workers have high level
of self-reported occupational health problems, particularly amongst welders and metalworkers.
Workers reported their needs as permanent workplaces, information on work related hazards, water

New Caledonian ultramafic ecosystems are considered as hotspots of biodiversity, partly because
of the adaptive pressure exerted by drastic edaphic conditions. These soils are composed of up to
85 % of iron oxides, are deficient in NPK, unbalanced for the Ca/Mg ratio and particularly rich in
heavy metals such as Ni (2%), Cr (2%), and Mn (1%). Consequently, intensive nickel mining
activities have created severe environmental hazard: large surfaces remain devoid of vegetation,
and have altered the structure of soil microbial communities. Both plant and soil microbes play a
vital role in the adaptation to harsh soil conditions mainly heavy metal uptake and tolerance. To
investigate the mycorrhizosphere bacteria (MB) diversities as well as on the genetic determinants
of resistance/adaptation of MB associated to endemic species of the genus Tristaniopsis
(Myrtaceae), about 200 ectomycorrhizas were sampled from four different ultramafic sites vs two
non-ultramafic ones from volcano-sedimentary soils. Molecular characterization of fungi (through
partial sequencing of the ITS rRNA gene) and related bacteria (through16S rRNA sequencing)
revealed the presence of different dominant fungi (Pisolithus albus, Russula spp., Boletellus spp.)
and bacteria (Burkholderia spp., Bacillus spp., Pseudomonas spp.). However, bacteria isolated from
ultramafic soils could grow in the presence of Ni up to 20 mmol L-1
, exhibited P-solubilizing
ability, .contained cnrT and nreB genes, known to confer heavy metal tolerance, contrary to
bacteria isolated from non-ultramafic soils. Further investigation on functional diversity of EM-
MB associations and their role in plant adaptation to ultramafic soils would help in successful re-
vegetation of these mine sites.

Miceller enhanced ultrafiltration (MEUF) technique was employed to remove the organic dye,
Reactive Blue 19 from the aqueous solution. The micelles of Sodium Dodecyl Sulphate (SDS), an
anionic surfactant and cetyl trimethyl ammonium bromide (CTAB), a cationic surfactant were used
for this process. The main principle of this process is to increase the size of pollutant molecules by
forming a complex with surfactant. The surfactant molecules form micelles, which can solubilize
the organic dyes. Micelles containing the dissolved solutes are then separated by ultrafiltration
using a membrane of suitable porosity, capable of retaining micelles. The regenerated cellulose
membrane was used to retain dyes from the aqueous solution in ultrafiltration cell. The constant
value of permeate flux throughout the experiment confirmed no membrane plugging. The large
size of dye containing micelle resulted in high rejection and low permeates flux.

Burning of crop residues is one of the popular residue management strategies globally, especially in
the developing countries. However, burning of crop residues creates multiple environmental
problems primarily due to emissions of trace gases. Pakistan is an agricultural country and
generates crop residues in huge amounts and dealing with crop residues is a great mess. Farmers
generally burn the crop residues to get rid of that waste material. Emissions from crop residue
burning include a wide range of gaseous compounds like CO, CO2, NOx, SO2, NO2, and NO which
contribute significantly to the tropospheric budgets on local, regional and global scales. In this
study the approach used in order to a) estimating the quantities of rice straw, rice husk, bagasse and
corncobs generated and fraction of that quantities being burned, b) investigate the gaseous
emissions and emission factors for trace gases from the burning of rice straw, rice husk, corn cobs
and bagasse, c) estimating the total emissions of trace gases. The average emission factors of CO,
CO2, SO2, NOx, NO2, and NO measured in the study were 14.04, 880.48, 0.11, 2.31, 0.19 and 1.38
g/kg for rice husk, 17.19, 1090.07, 0.38, 3.16, 0.89 and 1.48 g/kg for rice straw, 8.63, 595.44, 0.02.

bagasse, respectively. The total emissions of the trace gases CO, CO2, SO2, NOx, NO2, and NO
from the burning of rice husk, rice straw, corncobs and bagasse in Pakistan for the year 2011 were
estimated to be the 3.68, 230.51, 0.03, 0.60, 0.05 and 0.36 Gg for rice husk, 33.75, 2140.35, 0.75,

Sites co-contaminated with organic and metal pollutants are common and considered to be a more
complex problem as the two components often causes synergistic cytotoxic effects. Presence of
metals can inhibit the biodegradation processes in co-contaminated soils by adversely affecting
microbial growth or may interact with enzymes directly involved in biodegradation or in general
metabolism. The use of biosurfactants producing bacteria has potential for remediation of these co
contaminated soil heavy metals and petroleum hydrocarbon. The distinct advantage of
biosurfactants producing bacteria over other remediation technologies is their ability to reduce
metal availability thus enhancing solubility and biodegradation of petroleum hydrocarbons. So
biodegradation of petroleum hydrocarbon in the presence of metals can be enhanced by adopting
intervention strategies like metal resistant bacteria, application of treatment additives and clay
minerals. Adjustment of pH and addition of divalent cations could also be an additional strategy.

The use of synthetic antioxidants in food products is mostly discouraged because of their adverse
effects. In this work we evaluated the cytotoxicity and antioxidant, of absolute methanol extract and
its fractions from the Anticharis linearis plant. The GC-MS of essential oil and LC-MS analysis of
Phenolics in Anticharis linearis was carried out. The IC50 and the % inhibition in linoleic acid
oxidation was evaluated. Moreover, it was observed to provide a protective effect in H2O2 induced
oxidative damage in plasmid pBR322 DNA, indicating that the plant has antioxidant properties.
The results of present study revealed that plant may be considered as a good source of natural
antioxidants. The antioxidant activity of plant was also studied using sunflower oil as an oxidative
substrate. Peroxide value (PV), free fatty acids (FFA), conjugated dienes (CD), conjugated trienes
(CT) and para-anisidine values were also studied by stabilizing the sunflower oil as oxidation
substrate.

The detection and quantification of different pesticides in the goat milk samples collected from
different localities of Faisalabad, Pakistan was performed by HPLC using solid phase
microextraction. The analysis showed that about 50% milk samples were contaminated with
pesticides. The mean±SEM levels (ppm) of cyhalothrin, endosulfan, chlorpyrifos and cypermethrin
were 0.34±0.007, 0.063±0.002, 0.034±0.002 and 0.092±0.002, respectively; whereas, methyl
parathion was not detected in any of the analyzed samples. Quantitative structure activity
relationship (QSAR) models were suggested to predict the residues of unknown pesticides in the
goat milk using their known physicochemical characteristics including molecular weight (MW),
melting point (MP), and log octanol to water partition coefficient (Ko/w) in relation to the
characteristics such as pH, % fat, specific gravity and refractive index of goat milk. The analysis
revealed good correlation coefficient (R2 = 0.985) for goat QSAR model. The coefficients for Ko/w
and refractive index for the studied pesticides were higher in goat milk. This suggests that these are
better determinants for pesticide residue prediction in the milk of these animals. Based upon the
determined pesticide residues and their provisional tolerable daily intakes, risk analysis was also
conducted which showed that daily intake levels of pesticide residues including cyhalothrin,
chlorpyrifos and cypermethrin in present study are 2.68, 5.19 and 2.71 times higher, respectively in
the goat milk. This intake of pesticide contaminated milk might pose health hazards to humans in
this locality.

In the present study, a microcosm experiment was conducted to characterize the hexahydro-1,3,5-trinitro-1,3,5-
triazine (RDX) -degrading microbial populations at Darokdae (in South Korea) shooting site, contaminated with
explosives. In microcosm, set up with explosive-contaminated soil from shooting site, RDX transformation started
within three days of incubation and complete degradation was obtained after 12 days in microcosm amended with
starch (5g/L) (as external C-source). In microcosm amended with starch showed faster RDX degradation when
compared with microcosm without starch. Five metabolites including 4-nitro-2,4-diazabutanal (NDAB) were
observed in the live microcosm as transforming end products of RDX microbial degradation under aerobic
conditions. After two sequential transfers of RDX-degrading consortium, pyrosequencing analysis targeting
bacterial 16S rRNA genes showed Rhizobium-like populations predominanted in the microcosms. Other abundant
groups (over 10% in relative abundance) included Terrimonas, Rhizobacter, and Brevundimonas. However,
Rhodococcus and Pseudomonas spp. (which are well known as RDX-degraders) populations were not found in the
shooting site soil before and after incubation with RDX. In the live microcosm amended with starch (5g/L), only
Rhizobium genus increased over 30% in relative abundance after the incubation. Members of the genera
Rhizobium and Brevundimonas have been known to degrade RDX previously. The results suggest that the
microbial consortia in the soil, collected from shooting site, were able to degrade RDX aerobically and the soil
may harbor novel explosive degrading populations.

Department of Bioinformatics and Biotechnology, Government College University, Faisalabad
Lead and cadmium are the common environmental heavy metal pollutants with a widespread
distribution. Both natural and anthropogenic sources including mining, smelting, and other
industrial processes are responsible for human and animal exposure. These pollutants often act as
copollutants leading to concurrent exposure to living beings and resultant synergistic deleterious
health effects. Overproduction of reactive oxygen species and free radicals beyond the cell’s
intrinsic capacity leads to a state of oxidative stress and resultant damage of lipids, protein, and
DNA. In the first part of this study, human blood samples from lead exposed and control males
were collected and different biochemical tests were performed on sera by using kits. The results
indicated an increase in glucose concentration in lead exposed subjects. There was an increased
concentration of LDL cholesterol, triglycerides, albumin, alanine aminotransferase, aspartate
aminotransferase and total oxidant status in the blood serum of lead exposed subjects. A decreased
concentration was noted for HDL cholesterol, total proteins and globulin. The concentration of
triiodothyronine (T3) remained almost the same in lead exposed and control subjects indicating no
effect of lead intoxication on triiodothyronine level in them. Lead concentration was determined
from serum of lead exposed and control subjects by Atomic Absorption Spectrophotometer.
Structure prediction including primary, secondary and tertiary structure of an enzyme delta-
aminolevulinic acid dehydratase (ALAD), which is sensitive to lead toxicity, was carried out by
using bioinformatics tools. A software and web database were also developed for evaluation of
results. As second part of the study, a database and website related to cadmium induced oxidative
stress were developed containing information of all metabolic dysfunctions that are associated with
cadmium toxicity and cadmium elevation using data of the patients that includes different physical
and biochemical parameters. These parameters are affected by the cadmium quantity. The website
comprises information regarding diagnosis of cadmium affected patients, treatment and preventive
measures to avoid cadmium exposure.

In the present research the use of Laser Induced Breakdown Spectroscopy (LIBS) for determining
the contamination of soil with chromium due to effluents from tannery industry was reported. The
study was conducted at four locations around these industries which confirmed the leaching of soil
contaminants in horizontal direction. It has been found that concentration of chromium is up to 834
mg kg–1
in the soil which is much higher than the safe limits (100 mg/kg). Calibration curve for Cr
in soil matrix was also drawn for quantitative analysis. LIBS were found to be a viable technique
for qualitative and quantitative analysis of heavy metals like chromium (Cr) in the soil up to trace
levels.

Lower rainfall, reduction in irrigation water supplies and predicted climate change scenarios
require sustainable methods to increase crop productivity per unit of total water consumption i.e.
crop water productivity (CWP). Such increase in CWP can be achieved by improving water
management practices and use of novel irrigation technologies such as deficit irrigation. The
present research aims at evaluating the performance of AquaCrop model to simulate crop yield,
water productivity and Off-site water losses in the form of deep percolation. Field experiments
with different irrigation regimes: stored soil moisture/rain-fed, optimal irrigation and regulated
deficit irrigation at different growth stages were conducted on a loam soil for four crop seasons
(2008 -2012). Regulated deficit irrigation at less sensitive crop stage(s) could allow up to 20 %
water saving without compromising economic yield. AquaCrop simulations for in-season canopy
growth, biomass production, yield, soil moisture dynamics and water productivity under different
irrigation regimes were quite reliable. The model can be a useful tool for assessing crop
requirements and devising irrigation strategies to enhance water productivity under water limiting
conditions.

Current study was designed to appraise the antioxidant, antimicrobial and haemolytic potential
of Smilax macrophylla leaves. n-hexane fraction was analysed by GC/MS which revealed the
presence of 38 compounds. All examined extracts and fractions of plant leaves showed
significant antimicrobial activity. The haemolytic effect of the plant was found to be in a range
of 3.41-8.48%. S. macrophylla leaves contained substantial level of total phenolic contents (2.2-
6.2 GAE, mg/g) and total flavonoid contents (1.2-4.5 CE, mg/g) of dry plant matter. Leaves
extract and fractions also exhibited a good antioxidant potential when measured by DPPH
radical scavenging assay (IC50 = 33.4-72.3 µg/mL). The antioxidant activity of plant extracts
was also studied using sunflower oil as an oxidative substrate and found that it stabilized the oil.
The correlation between the results of different antioxidant assays and oxidation parameters of
oil indicated that leaves extracts and fractions, contained considerable TPC, TFC, and
scavenging power, and was potent for enhancing the oxidative stability of sunflower oil.
Considering these results, S. macrophylla could be used as a source for the exploration of new
antimicrobial, antioxidant agents, functional food and nutraceutical applications.

OXIDATIVE STRESS-INDUCED DNA DAMAGE BY PARTICULATE AIR
POLLUTANTS IS IMPLICATED IN THE DEVELOPMENT OF FATAL DISEASES
Muhammad Ibrahim Rajoka, Shazia A. Bukhari and Asma Haque
Department of Bioinformatics and Biotechnology, GC University, Faisalabad, Pakistan
Exposure to ambient air particulate matter (PM) is associated with the development of pulmonary,
cancer and cardiovascular diseases. The mechanisms of PM-induced health problems are due to the
involvement of inflammation and oxidative stress. PM mediated oxidative stress may generate
reactive oxygen species (ROS ) from the surface of particles, soluble compounds of transition
metals or organic compound, altered function of mitochondria or NADPH-oxidase, and activation
of inflammatory cells capable of generating ROS and reactive nitrogen species (RNS). Resulting
oxidative DNA damage may be implicated in development of cancer and may serve as marker for
oxidative stress related to other ailments caused by particulate air pollution. Studies on animal
experimental models, cell culture experiments, and cell free systems have proved that exposure to
diesel exhaust and diesel exhaust particles causes oxidative DNA damage. The mechanisms
involved in the action of PM has prompted the use of markers of oxidative stress and DNA damage
for human biomonitoring. Proteins are oxidized forming carbonyl moieties in such circumstances.
Similarly lipids and carbohydrates are oxidized and laed to their increased accumulation in blood
stream. In both indoor and outdoor exposure to PM (2.5 nm) has been correlated with guanine
oxidation in DNA. Oxidative stress-induced DNA damage appears to be an important mechanism
of action of urban particulate air pollution. Total homocysteine (THcy) in blood is enhanced and
brings about enhanced oxidative stress in favour of oxidants. Efforts may be made to reduce DNA
damage and THcy by proper implication of nutrigenomic approaches.

simulated under diverse constraints and the results were analyzed. The performance parameters such as open
circuit voltage VOC, short circuit current JSC, fill factor FF, and efficiency η were evaluated. It was found that the
thickness and doping of the emitter and the base have dynamic effects on the device performance. Moreover, it
was found that VOC and JSC are strong function of Indium concentration. The simulated results are in consistent
with the recently published data. These results suggest that deployment of III-Nitride solar cells as future
technology have colossal potential of attaining high efficiency. The challenges that hamper the growth of such a

Coal is the cheap and innate energy resource in Pakistan. According to NEPRA Pakistan, Thar coal
resources can generate more than 100,000MW electricity for next 30 years. Pakistan which is an
agricultural country, biomass is interesting option by keeping in view the production and
performance of biomass. Biomass co-firing (or combustion) involves the combination of fossils
based (pulverized coal) power plant with biomass stock. The fuel properties like high level of
moisture, high chlorine content, and low heatig level make suitable conditions for co-firing. The
Cofiring of biomass with coal can lessen the harmful hazards and save coal for next years. The
working of Coal Power Plant and Co-firing of biomass in three different ways i.e. Direct Cofiring,
Indirect Cofiring and Parallel Cofiring have shown that it is a green technology, due to carbon
neutral effect as well as reduction in green house gases. The growth rate of agricultural sector,
social-economic and environmental assessment of coal combustion with biomass have shown that it
is an profitable, sustainable technology and environmental friendly.

The characterization behaviour were studied for the thin-film p-i-n solar cell based on hydrogenated
nanocrystalline silicon (nc-Si:H) aborber layer. Till now, hydrogenated amorphous silicon (a-Si:H) has been
extensively used for p-i-n solar cell technology because of its better characteristics such as higher absorption
coefficient, and lower material costs. However, defects present within a-Si:H degrades the conversion efficiency
of such solar cells. We proposed incorporating newly developed nc-Si:H absorber layer instead of a-Si:H that
contains crystalline phase mixed with amorphous phase. The proposed p-nc-Si:H/i-nc-Si:H/n-a-Si:H solar cell
structure had been simulated with Silvaco TCAD (ATLAS). The influence of intrinsic layer absorber thickness on
characterization behaviour such as open circuit voltage (Voc), short-circuit current (Isc) and conversion efficiency
was investigated. Simulated results showed that it is preferable to employ nc-Si:H for thin-film p-i-n solar cell
technology because of its better mobility, stability and lower material costs.

World is facing a rising epidemic of global environmental problems. Modern communication has brought us into a
closer contact with every part of the world; we are compelled to recognize that all the Earth inhabitants share a
common environment and its related problems. With the onset of industrial revolution in 1700s, increasing use of
80
fossil fuels has resulted in enormous emissions of Carbon Dioxide into the atmosphere on burning. The increasing
domestic and industrial energy demands coupled with an increase in the technological abilities has strengthened
our potential for altering the environment we live. We have no choices but to learn to live sustainably, with little
impact on our environment. Otherwise, the prospects for future generations are indeed bleak. This present study
aims to calculate carbon footprint of energy consumption in Nestle’ milk collection centers in Pakistan.IPCC
Guidelines for National Greenhouse Gas Inventories 2006 aids in the various calculation that are undertaken in
carbon footprint estimation. Nestle’, a globally known company, promises quality, health and nutrition to its
consumers through a wide range of products and also addresses the wellbeing of the environment through
estimating and mitigating its environmental impacts continuously. The contributions to climate change by
company’s operations were realized by the company and the present study’s objectives are to calculate the carbon
footprint resulting from the company’s energy consumption at the Milk Collection Centers. All the energy and
fuel consumption data were provided by the company that made the estimation of contributions of the Company’s
Milk Collection Operations towards the global warming possible. It is estimated that a total of 5337.076 tons of
CO2 emissions results from energy consumption by the milk collection centers all over the country. The aim for all
is Carbon neutrality, which though is quite hard to achieve but is not impossible.

Thyroid gland is located in the neck and enlargement of this gland is known as goiter. When the
supply of iodine to the thyroid gland is inadequate for the formation of sufficient quantities of
thyroid hormones, goiter appears. In the present study prevelance and epidemiological risk factors
of goiter in Hyderabad and adjoining areas has been studied with the help of a standard
questionnaire. The important findings of this study are summed up as under: Amongst the patients
referred to Atomic Energy Medical Centre Jamshoro for goiter screening and treatment, females
were seen to be more prone to develop goiter than males, with an overall female to male ratio of
5:1. In both sexes, the prevalence of goiter was maximum in 15-25 year age group. Family history
was positive in 22.45% cases. Of the goiter patients 77.22% belonged to Hyderabad city and
84.85% were sedentary by occupation. Goiter was more prevalent in surface water drinker
(80.75%) than in ground water consumers (19.25%), in mine salt consumers (67.55%) than in sea
salt intakers (32.45%). Screening of goiter patients by blood chemistry revealed that 5.17% and
2.50% cases had hyperthyroid and hypothyroid respectively. Nodular non-toxic goiter was found in
6.71% cases, nodular toxic in 0.28% cases and solid adenoma/cyst in 24.45% cases. It seemed
essential to monitor the iodine content in water of this area to ascertain whether the iodine
deficiency is the cause of sporadic goiter. As iodine content in water is generally taken as an index
of the iodine intake. Therefore 100 water samples were collected and analyzed by Ion selective
electrode method. Results showed that iodine contents in water are within permissible limit i.e. not
lower than 3µg/l. This indicates that iodine deficiency in water of studied area is not isolated
epidemiological phenomenon for goiter genesis.

Haleji lake as compared to Keenjhar lake however, 87.5% of the samples exceeded the acceptable
limits in both the lake water samples. Faecal coliform count exhibited seasonal variation in both the
lakes whereas, total average (aerobic) bacterial count (determined in both the lakes) was 102
CFU/ml – 107 CFU/ml. A total of 109 bacterial isolates from both the lakes (Haleji and Keenjhar)
were screened for bacteriocinogenic potential. The physico-chemical characterization was taken
into account for the best producer strain identified as Bacillus circulans HA12. The bacteriocin by
B. circulans HA12 was designated as bacillocin HA12, antagonistic to only gram-positive bacteria
(namely Brevibacillus brevis, B. subtilus, Staphylococcus aureus, Micrococcus luteus) and a few
fungi (Microsporum gypseum). The inhibitory activity was inactivated rapidly by proteolytic
enzyme (proteinase K) while, lipolytic enzymes had no influence on the bioactivity. The activity
remained intact after the bacillocin HA12 exposure to heavy metal ions, organic solvents, protease
inhibitor and surfactants. Stability was observed at low & high temperatures and at broad (2 – 12)
pH range. Its electrophoregram exhibited a single band of molecular weight of about 10 kDa. This
study was intended to make certain the access of safe and potable water to urban and rural areas of
Sindh. The properties of bacillocin HA12 like thermal stability and sustainable activity at low
temperature and at broad pH range are the desirable attributes of this bacteriocin which may allow
its utilization as biopreservative, food additive and in public health products.

Zinc is a trace element that supports cellular integrity and required for biological functioning. Zinc
is present in biological system in divalent cation with (– 0.763) radox potential. Zinc serves as a
85
cofactor in all six classes of enzymes and in number of regulatory proteins including zinc finger
proteins and transcription factors. The current bioinformatics studies showed that zinc, copper and
iron compose 10 % of bacterial and about 13 % of the aracheal proteomes. Zinc-binding proteins in
E. coli is 3 % of its total proteins those form a stable association due to its flexible coordination
geometry, making it highly adapted to meet the needs of proteins by rapid shift of conformations
and to perform diverse biological functions. Zinc acts as strong Lewis acid or electrophile in many
protein catalyzed reaction in which it catalyses the substrate by ionization of zinc bound water
molecule, polarization and activation. Zinc is an antioxidant and retards the oxidative mechanisms
through steric hindrance, conformational changes in protein structures and neutralizes the Reactive
Oxygen Species (ROS), produced in various catalytic reaction of redox active metals. Zinc
increases the resistance of cell by stabilizing the mitochondrial membrane that prevents the ROS
mediated apoptosis and protects membranes from iron-initiated lipid oxidation by occupying
negatively charged sites with potential iron binding capacity. It protects sulfhydryl containing
proteins and maintains optimal levels of metallothioneins (low-molecular weight metal-binding
proteins). Zinc superoxide dismutase scavenges the ROS and control oxidative stress. All of the
described mechanisms suggest that zinc is an essential constituent of the antioxidant defense
system that protects membranes from oxidation. The purpose of this review is to consider whether
an essential biochemical function of zinc is to serve as an antioxidant?

The structure and functioning of the ecosystem and the health of organisms are at high risk because
of the accruement of metals in different zones of ecosphere and their potential mobilization under

environmentally changing conditions. The heavy metals are present in soil in different speciation
and sorption/desorption mechanisms are contingent to biotic and abiotic factors that influence soil-

speciation influence the bioavailability of heavy metals their transport and intake in various food
chains. it is key factor to the chemical and physical reactions that heavy metals experience in soil
and which determine the mobility and transport in different soil matrixes, their possible toxicity, the
nature of their association with other soluble species. Furthermore, the ability of soil to release
metal from solid phase to refill that absorbed by plant from soil solution also depend upon
speciation.

Hospitals produce a large amount of hazardous and infectious waste. Improper management of
medical waste can cause serious threat to hospital workers, waste handlers, community as well as
the environment and can make public vulnerable to the communicable diseases such as AIDS,
hepatitis, typhoid and many other diseases. The objective of this project was to design proper plan
87
for handling medical waste that includes different steps such as waste generation, storage,
transportation, safe processing and finally disposal in a proper place. According to environment
protection agency (EPA) improper disposal of regulated waste is aesthetically damaging the
environment. Lack of medical waste disposal management can increase the risk of infections and
diseases to the public and can pollute the environment. Medical waste management is receiving
greater attention due to potential health risks arising from inappropriate disposal and treatment of
the waste. Such waste typically contains a variety of potential infectious and toxic material.
Keeping the health problem caused by improper management of medical waste in view, the current
study was planned to evaluate the situation of hospital waste management in district Faisalabad and
to realize the responsibility of government in mandating, initiating, facilitating and reduction of the
poor impacts related to environment and human health in district Faisalabad. The study was based
on the walk through survey, interview and questionnaires.

In the modern era industrialization has cruised so much, as its harmful effects has also increased
steeply. The waste products of industries are continuously being released in rivers, ponds and lakes,
flowing nearby. These wastes are mostly released without any safety treatment. The sewage-sludge
from the city is being disposed to agricultural land that is under the cultivation of different crops.
88
This had led to accumulation of micronutrients in the soil resulting in their enhanced uptake by the
plants. As high levels of micronutrients may cause human and animal health hazards after entering
in their system through food chain and waste water, having high load of micronutrients can exert
adverse effect on the growth and yield of the plant so, the present study was planned to investigate
the effects of waste water on the growth of mungbean. The experiment was conducted to access the
influence of exogenously applied waste water on physiological character of mungbean (Vigna
radiata L.). The treatment was applied on three weak old plants. The plants were harvested two
weak after the application of waste water .Growth parameter i.e. plant height, root length, fresh and
dry weight, number of leaves and leaf area per plant were recorded. Lab and pot experiment were
conducted to check the growth in term of growth parameter and chlorophyll extraction. Root
length, shoot length, fresh and dry weight declined with the application of waste water. Chlorophyll
has minor or no difference with waste water treatment. In our study it was found that waste water
treatment reduced plant growth and growth related parameters when applied in undiluted form.
However, at least 50 % dilution of waste water is needed to reduce the effect of toxicity and to
enhance or improve the growth and growth related parameter before its application on Vigna
radiata plants.

Climate change and environmental stresses have posed threats to the global food security. Water
deficit, one of the most limiting abiotic stresses has devastating effect on agricultural extension and
crops productivity. An experiment was conducted to investigate the biochemical modifications
triggered in canola (Brassica napus) seedlings after exogenous calcium supplementation followed
by imposition of water deficit stress by withholding the irrigation water supply for 10 days. It was
observed that water deficit stress increased the accumulation of proline, hydrogen peroxide,
89
catalase and ascorbate peroxidase activity. Exogenous calcium supplementation further increased
the accumulation of proline and catalase and ascorbate peroxidase activity but decreased the
hydrogen peroxide content under water deficit stress condition. Thus, supplemental calcium proved
to have beneficial effects of canola seedlings exposed to water deficit stress.

Aflatoxins are noxious metabolites produced by certain fungi in foods and feeds. They are probably
the best known and most intensively researched mycotoxins in the world. Aflatoxins have been
allied with various diseases, such as aflatoxicosis, in livestock, domestic animals and humans
throughout the world. It is a problem, particularly in developing countries. Aflatoxins are produced
primarily by some strains of Aspergillus flavus and by most, if not all, strains of A. parasiticus, plus
90
related species, A. nomius and A. niger. It is discovered that there are four major aflatoxins: B1, B2,
G1, G2. Aflatoxin development in many stored cereal grains has hampered the availability of good
quality grains. It may cause severe health hazards to human, animals as well as can create great
economical problems. In this study hundred samples of paddy rice were tested for aflatoxin
contamination. Fifty samples were self dried in one step while fifty samples were let to be dried
conventionally by the huskers i.e. first semidrying up to 16 -18 % moisture contents and then final
drying up to 12-14 % moisture level after certain storage period depending upon paddy purchase
period of each husking unit. The aflatoxins was detected in paddy rice by using VICAM Series-
4EX Fluorometer™ which is a based on monoclonal antibody- based affinity chromatography.
Almost all the self dried samples have aflatoxin level below the European maximum permissible
level while the rice samples dried conventionally at husking units were contaminated with aflatoxin
more than the European maximum permissible level for brown rice. The production & high level of
these lethal aflatoxins due to conventional post harvesting techniques causes serious threats to our
environment, human & animal population. This may lead to several toxicological problems in our
ecology & environment. On consumption of such food or feed an individual may suffer from
immunosuppression, cancer, toxicity & other abnormalities. So such conventional methods of
drying should be avoided to create any serious threat to environment, human & animals.

of 572 to 1927 mg/Nm3, 21714 to 131429 mg/Nm
3 and 315 to 2297 mg/Nm
3 respectively. The SO2
contents were ranged from 0 to 3383 mg/Nm3 in boilers and 65 to 265 mg/Nm
3 in generators. H2
92
concentration varied from 0.09 to 174 mg/Nm3 in boilers while 0.7 to 4.0 mg/Nm
3 in generators. In
boilers and generators the flue gas temperature was as high as 400oC and 521
oC respectively with
ambient temperature in the range from 30 - 45oC at workplace area. The noise generated by boilers
was in the range of 94 to 97 dB(A) at 1 m distance and 75 to 84 dB(A) at 7 m distance. Similarly
for generators, noise recorded in the range of 91 to 97 dB(A) at 1 m and 81 to 89 dB(A) for 7 m
distance. Smoke opacity of these industries varied from 2 -30% boiler stacks and 25 - 46% in
generators. Overall efficiency of industrial source points calculated to be 75.8 - 91.7% for boilers,
whereas 53.6 - 76% for generators. The results of present work revealed the fact of air pollution
stress generated by different industries in Faisalabad and most of the industries examined for
gaseous emissions were found to be exceeding the limits of national environmental quality
standards for CO, CO2, NOx and SO2 thus generating the environmental pollution.

Municipal management of solid wastes is a complicated task to be done by the local Government
requiring a good organizational structure and working staff with equipments. The term Municipal
wastes encompass all kind of non- hazardous waste collected from household, commercial and
industrial sector of the city. MSWMS (Municipal Solid Wastes Management System) is very
significant to prevent the city dwellers from various environment and health related problems.
MSWMS include collection, storage, and compaction, Transportation, dumping and recycling of
waste material. It is a cyclic process that’s needs a good management system. The major objective
of the paper is to explore the management process of solid wastes by Tehsil Municipal
Administration Bahawalpur and the problems associated with its management process. The paper
analyses the results of field survey of wastes dumping sites and treatment process. TMA Chief
Officer of Infrastructure and services department is interviewed and problems associated with its
96
management are analyzed. It is concluded from the research that municipal service for solid waste
management exists for almost 100% population of the city, although there are many infrastructure
and finance problems existing that hinders the good management plans. Insufficient machinery and
equipment in TMA is making the collection and transportation process more difficult and
decreasing the waste collection rate. Moreover, distribution of wastes dumping sites in the city is
quite inappropriate and causing severe negative impacts on the surrounding environment like
Ground water pollution, noise pollution and various health related diseases. The paper addresses
the strategies that can make the management system more efficient through public and private
sector participation with city TMA .

Biofilm is a dense aggregate of surface-adherent microorganisms embedded in a polysaccharide
matrix It is a serious threat to increase the onset of diseases. The most alarming consequence of
biofilm formation is the multiplication of pathogens such as E.coli, Pseudomonas and Salmonella.
The present study was conducted to isolate E. coli and to check the efficacy of disinfectants to
control biofilm formation. A total of 40 biofilm samples were collected, from different commercial
poultry farms of broiler and layer birds. Samples were inoculated on MacConkey agar and
inoculated plates were incubated at 37°C for 36 hours. Isolated microorganisms were identified
through conventional method. The ability of isolates to form biofilm on Poly Vinyl Chloride (PVC)
pipe and iron pipe was determined. Efficacy of commonly used disinfectants was also determined
against Escherichia coli isolates. The results showed that out of 40 samples, 32 samples were
positive for E.coli. Iron pipe was found more susceptible for biofilm formation as viable count of
E.coli was more on iron pipe (1.99× 106
cfu) and less on PVC pipe (1.48 × 106 cfu). Among 4 used
97
disinfectatnts, TH4 (contains tertiary chlorides and glutarldehydes) was found most effective
disinfectant as it reduced viable count of E.coli from 110 × 106 to 55 × 10
2 cfu. It was concluded
that biofilm is a serious threat as it contributes many species of bacteria but major one is E. coli. It
is recommended that by using of PVC pipe instead of iron pipe and regular water disinfection may
solve the problem of biofilm formation in water distribution networks.

Fusarium wilt, caused by Fusarium solani, is an economically important disease of potato in
Pakistan. Presently, pathogenic potential of F. solani was studied by inoculating potato plants with
three F. solani, strains to screen the most virulent isolate among F. solani FCBP-016, F. solani
FCBP-434 and F. solani FCBP-470. Pathogenicity test depicted that F. solani FCBP-434 was the
most pathogenic isolate with variation in genetic level that was determined by RAPD-PCR. F.
solani FCBP-434 was 55.66% different with both isolates. This disparity in genetic constitution
might be cause of high pathogenicity. Afterwards, antifungal bioassays were conducted to confirm
mycotoxic potential of root, shoot and leaf of Parthenium hysterophorus against F. solani FCBP-
434 using 1-4% concentrations of aqueous, methanol and n-hexane extracts. Bioassays revealed
that growth of F. solani FCBP-434 was greatly inhibited at 1 and 2% concentrations of aqueous
and methanol leaf and stem extracts while 3 and 4% concentrations of n-hexane extract proved
more effective in suppressing the growth. Among root extracts, higher concentrations of aqueous
98
and n-hexane exhibited more promising results by causing reduction of 85 and 74%, of the growth,
respectively, whereas in methanol extract again lower concentrations were more inhibitory.

Tomato (Lycopersicum esculentum Mill.) is one of the most economically important vegetable
crops in the world. It is estimated that diseases reduce tomato production to a greater extent
worldwide. Natural plants derived compounds contribute a lot in fight against pathogens. In the
current study the tomato plants were inoculated with A. alternata FCBP-573, A. alternata FCBP-
479 and A. alternata FCBP-349 for the scrutiny of the most pathogenic isolate among these. A.
alternata FCBP-573 was screened out as the most pathogenic isolate. RAPD analysis confirmed
that A. alternata FCBP-573 had variability in its genetic constitution with other two isolates; thus
this disparity in genetic constitution might be a cause to stir up more pathogenicity in this isolate.
Therefore, A. alternata FCBP-573 was selected as the most pathogenic isolate and subjected to
biological control through Tagetes erectus L. In antifungal bioassays different plant parts of T.
99
erectus with 1-4% concentrations of aqueous, methanol and n-hexane extracts of each part were
evaluated against A. alternata FCBP-573. Results revealed that the growth of A. alternata FCBP-
573 was greatly inhibited at 4% concentration of methanol extract followed by aqueous and n-
hexane extract. Among different plant parts tested, root extract exhibited more promising results by
causing 81-92% reduction in biomass. The study concludes that aqueous and organic extracts of
ornamentals have potential to obstruct dreadful effect of pathogenic fungi by suppressing their
growth. T. erectus conferred vital and surprisingly stable compounds having inhibitory potential
against A. alternata FCBP-573.

Environmental contamination due to xenobiotic compounds is mainly due to their large-scale
manufacturing, processing and handling. Owing to long-term persistence, and acute toxic and
teratogenic effects of these compounds.Due to its capability to degrade toxic xenobiotic compounds
in a safe and cost-effective manner, interest in bioremediation using microorganisms, particularly
bacteria and fungi, has increased in the past two decades. Partial microbial degradation of
xenobiotic compounds in wastewater treatment plants results in the formation of transformation
products, which have to be released and detectable in surface waters. The accumulation of
recalcitrant xenobiotic compounds is due to continuous efflux from population and industrial inputs
that have created a serious impact on the pristine nature of our environment. Metabolic pathways
and specific operon systems have been found in diverse but limited groups of microbes that are
responsible for the transformation of xenobiotic compounds. Distinct catabolic genes are either
present on mobile genetic elements, such as transposons and plasmids, or the chromosome itself
101
that facilitates horizontal gene transfer and enhances the rapid microbial transformation of toxic
xenobiotic compounds. Remediation is the only way to tackle these so called xenobiotic
compounds and to reduce the hazards caused by them. Even though, several practices have been
implemented for degrading these recalcitrants, bioremediation step is proved to show the
significant impact on them. In present article we have reviewed the role of microbes in
biodegradation of various xenobiotic compounds escepieally releted to waste material of petroleum

Parthenium (Parthenium hysterophorus L.) is a rapidly growing invasive weed native to America
that has invaded Asia, Africa and Australia during the last 50 years. The weed is growing
abundantly along the road sides, on waste lands and grazing pastures as well as in agricultural
fields and produces a huge biomass. It has adverse effects on agriculture and natural ecosystems
and also poses serious health risks such as allergic contact dermatitis, rhinitis and asthma. In the
present study, pot experiments were conducted to evaluate the potential of parthenium weed to be
used as green manure. Maize (Zea mays L.), wheat (Triticum aestivum L.) and mungbean [Vigna
102
radiata (L.) Wilczek] were used as test crops. Treatments employed were control, recommended
NPK fertilizers, and 1, 2, 3 & 4% (w/w) parthenium green manure (on fresh weight bases).
Parthenium was collected at 30-35 days growth stage prior to flowering. After mixing the
parthenium manure in the soil, pots were irrigated and left for 30 days for decomposition. Highest
root and shoot biomass in maize was obtained in 3% green manure treatment that was significantly
greater than control and equivalent to that of NPK fertilizers. Similarly, a 4% green manure
treatment of parthenium significantly enhanced growth and yield of wheat, and grain yield
equivalent to recommended dose of NPK fertilizers was obtained. In contrast, the effect of both
NPK fertilizers and parthenium green manure on growth and yield of mungean was insignificant.
The present study concludes that huge biomass of noxious parthenium weed can be managed by
using it as green manure for maize and wheat crops.

An-aerobic reactors are proved to be ineffective to disinfect the municipal wastewater. However,
an-aerobic treatment of wastewater in conjunction with an adequate post-treatment can provide a
good quality wastewater to be used for irrigation or for other applications. In this study, advanced
oxidation processes like ozonation, UV irradiation, hydrogen peroxide and their combinations
(O3/H2O2, O3/UV and UV/H2O2) in addition to sunlight were used to disinfect the UASB treated
municipal wastewater. All the processes gave encouraging results with minor differences with one
another however cost effectiveness of sunlight cannot be denied. Using ozone as treatment
provided frequent elimination of various pathogens included in this study. An optimal dose of 30
min eliminated 99.9 % of pathogens and showed great potential of inhabiting re-growth of these
pathogens. UV irradiation was also proved to be an efficient process for eliminating pathogen
content but it appeared to be a costly process. However, UV irradiation also achieved better results
like ozonation. UV irradiation with an intensity of 5 mW/cm2 and wavelength of 254 nm resulted in
99.9% pathogen removal when a UV dose was applied for 480 sec. Treatment with H2O2 was
appeared to be the cheapest treatment among the AOPs. A H2O2 dose (35 % conc.) of 0.9 ml/L was
103
appeared to be optimal providing more than 99 % removal of pathogens. Treatment using
combinations was proved the most effective tool for the disinfection of wastewater requiring
comparatively low doses of disinfectants than individual processes. Using O3 and H2O2 in
combination (O3/H2O2) gave 99.9 % removal of pathogens when wastewater sample was treated
with 0.25 ml/L of H2O2 and later disinfecting with O3 for 10 min. similar result were obtained with
(UV/H2O2) at 0.3 ml/L of H2O2 dose and 1 min exposure time of UV irradiation. In case of O3/UV
treatment system, the effluent was 99.9 % clear from pathogens at 10 min O3 and 240 sec UV
irradiation post ozonation. Solar disinfection was effective in vivo as a free, low technology, which
proved to be an efficient method of improving water quality. In the present study, sunlight has been
proved to be an attractive technique for the removal of pathogens. A removal of 99.9% of
pathogens was obtained at a solar irradiation time of 150 min with an average intensity of 75 mW/
cm2. In this study solar disinfection was also used in combination with H2O2, which appeared to be
an attractive and cost effective treatment process resulting in appreciably reduced contact time with
sunlight and high rates of pathogen removal. Sunlight /H2O2 treatment achieved 99.9 % removal of
pathogens when wastewater sample was treated with 0.25 ml/L of H2O2 dose and then irradiated
with sunlight for a contact time of 30 min.

With the increase in world’s population and more resistant pests, the use of pesticide is increasing
day by day. Now this practice is creating disturbances in ecosystem as pesticides remain in soil, air,
surface and ground water for longer duration. Microbes which consistently come in contact with
pesticide develop the ability to degrade them into non-toxic products. In present study, microbial
strains were isolated from cotton growing agricultural soils where chlorpyrifos was extensively in
use. The isolated strains were significantly different in their resistant towards chlorpyrifos. Out of
these strains, Klebsiella sp. was found most resistant (50mgL-1
) and was selected for follow up
studies. Different culture conditions like, chlorpyrifos concentration, added nutrients, pH and
inoculum densities were tested to maximize the biodegradation of chlorpyrifos by Klebsiella sp. In
minimal salt medium Klebsiella sp. exhibited 75% of chlorpyrifos (50mgL-1
) degradation in 22
days of incubation. Kinetic analysis reveals that the Klebsiella sp. shows longer lag phase at high
concentration of chlorpyrifos. This strain can be used for bioremediation and ecological restoration
of sites, contaminated with chlorpyrifos.

Effluent is a discharge of waste water from industrial site that is contributing to environmental
pollution. Effluent or the waste water is mainly generated as a result of the production processes
within the industries especially food, oil, textile industries and nuclear waste which not only harms
the environment but also micro and macro flora within it. Rapid industrialization generates tons of
hazardous waste comprising conventional and toxic pollutants that is causing damage to
ecosystem.Therfore, industries are searching for effective and sustainable technologies for
disposing of their wastes. Breakthrough of eco-friendly bioremediation process has provided use of
microorganisms to deal with contaminants and transform them into innocuous end products and to
reclaim the environment into its original state. Bioremediation is a technique to eliminate, degrade
or transformed toxic agent to non-toxic ones by employing biological processes, and using
microbial species in both natural and man-created remediation processes. In present article we
reviewed waste material released from different industries and the method to check the accessibility
and biological activity of microorganism to transform voluminous industrial effluents to less toxic
products

Municipalities in the three important and major cities of Khyber Pakhtunkhwa namely Peshawar,
Mardan and Nowshera districts are facing hard challenges in solid waste disposal due to the lack of
landfill capacity in these cities. With rapid urbanization especially over few decades, the
movement/migration of Internally Displaced People (IDPs) towards these districts has made solid
waste a serious reason of causing negative impacts on human health as well as environmental
degradation affecting urban ecosystem. This study aims to estimate the total quantity of solid
wastes generated in these three districts and evaluate the present solid waste management systems.
According to the field survey conducted in January 2012 and data from municipalities estimates,
the average per capita household waste generation rate is 0.67 kg/capita/day in Peshawar, 0.54
kg/capita/day in Mardan and 0.42 kg/capita/day in Nowshera and the total daily waste generation is
1000 tons in Peshawar, 850 tons in Mardan and 740 tons in Nowshera districts on daily basis. This
study indicated that approximately 65 percent of waste is collected by the municipalities of these
cities while remaining 35 percent is thrown either into waterways or lying in the street or road sides
which poses serious health risks to inhabitants. This research identified the serious needs of public
awareness, implementation and execution of creative and innovative approaches/technologies like
106
reuse and recycling opportunities, disposal of the solid waste on a landfill with electricity
generation and composting of organic materials to overcome related human health and
environmental issues. After this extensive study of three important districts, the authors strongly
feel that there is an intense need of proper legislation and policies regarding solid waste
management in the country.

Biosorption has been regarded as a low cost method for the removal of contaminants especially
heavy metals from aqueous solutions. Biosorption puts to use the characteristic of biological
materials to accumulate the heavy metals by metabolic or physio-chemical pathways. The
accumulated biological materials along with heavy metals are further filtered. This process depends
on variables such as temperature, agitation speed, pH, amount of adsorbent and concentration of the
initial solution. Adsorption performance of Cr (III) and Ni (II) on dried Phalsa (Grewia asiatica)
leaves powder was studied. It shows an appreciable removal efficiency for Cr (III) and Ni (II) and
removed from their aqueous solution up to 87.89% at pH=4 and 95.48% at pH=5, respectively.
Optimum adsorption conditions were determined as a function of adsorbent dosage, contact time,
pH and agitation speed. Langmuir, Freundlichand and Temkin isotherms were used to evaluate the
equilibrium data. The adsorption capacity q max of Cr (III) and Ni (II) is found to be 6.002 mg/g
and 3.815 mg/g of adsorbent respectively. The observed Cr (III) and Ni (II) removal order is Cr
(III) > Ni (II).

To study the plant response to cadmium (Cd) stress in combination with a growth regulator, 5-
aminolevulinic acid (ALA), oilseed rape plants were grown hydroponically in greenhouse
conditions under three levels of Cd (0, 100, and 500 μM) and foliar application of ALA at three
concentrations (0, 12.5 and 25 mg/l). Cd stress depressed the plant growth in terms of plant
biomass, plant height, root length and reduced chlorophyll contents in the leaves; however foliar
application of ALA significantly improved the plant growth and enhanced the chlorophyll synthesis
in the leaves. Generally, analyses of macro (N, P, K, S, Ca, and Mg) and micronutrients (Mn, Zn,
Fe, and Cu) showed reduction of accumulation of these ions in the leaves and roots under higher
concentration of Cd (500 μM). Exogenous application of ALA enhanced the concentration of all
the nutrients except P and S. Results have shown that foliar application of ALA significantly
decreased the production rate of MDA and ROS in the leaves of brassica. Antioxidant enzymes
like superoxide dismutase (SOD) and guaiacol peroxidase (POD) decreased significantly whereas
ascorbate peroxidase (APX) and catalase (CAT) showed increase in their activities under 500 μM
Cd. The antioxidants enzymes enhanced their activities when ALA was applied with the
combination of different Cd concentrations. The study also reveals that seedlings treated with ALA
at different concentrations enhanced the glutathione reduced (GSH), glutathione oxidized (GSSG),
total glutathione and reduced the GSH/GSSG ratio in leaves under different levels of Cd stress. Our
112
results indicate that ALA helped the plants to improve the uptake of nutrients and antioxidants
enzymes due to its ameliorative capability under Cd stress conditions.

The cotton plays a vital role in the national economy. Contamination by heavy metal is an
important environmental issue worldwide, particularly in the agriculture sector, as it confines the
crop production and its quality. Soil management techniques should be used for contaminated soil
to reduce the availability of heavy metal to the plants. Keeping in view, this study was planned to
investigate the alleviating effects of Silicon on different Physiological, morphological and
biochemical attributes of cotton plants under Nickel (Ni) stress. Cotton plants (MNH-886) were
exposed to the three replicate of each two level of Ni (50µM and 100µM) in form of NiCl2, with or
without 1mM of Silicon (Si) as Na2SiO4 in hydroponic culture at pH 6.0 + 1.0. After eight weeks of
Ni stress exposure, the finding depicts that increase in the concentration of Ni in the growth
medium of the plant significantly affected the biological activities like synthesis of protein contents
and antioxidant enzymes (SOD, POD) that caused not only decreased in growth rate of the plant
but also damage its physical structure The transformation of the (O2¯) radical into H
2O
2 are
basically supported the SOD activity in the plants cell which considerably increased with the
presence of Ni but it showed the non-significant behavior if plants were exposed to higher
concentration of Ni for a long period. Cotton plant has the ability to survive for a long time period
under stressed condition of Ni50 with respect to the Ni100. Alteration in the biological activities
disturb the chlorophyll contents that effect the photosynthesis rate ultimately caused substantial
reduction in the leaf, shoot and roots growth as well change do occurred in their physical structures.
The rate of Ni accumulation in roots was found much higher than of shoots and leaves. Induction of
Silicon (Si) as an alleviating agent to plants supported them to cope up maximum in case of Ni
113
stress by enhancing the biological activities ultimately led to increase in growth rate of the cotton
plants.

Microbiological qualities of drinking water have fundamental importance for poultry. Due to poor
hygienic conditions in water supply, it is becoming a health hazard for the poultry. Present study
was designed to analyze the bacteriological quality of water supplied to poultry farms and evaluate
the efficacy of different disinfectants to reduce the microbial load of water at commercial broiler
farms. Water samples (n=50) were collected from broiler farms in and around Lahore. Water in
poultry environment was of low quality as detected by Total Viable Count and Coliform count.
Commercial preparations of various disinfectants (PHMB, PHMB + Benzalkonium chloride + non
ionic surfactants, Chlorine dioxide, Glutralaldehyde and organic acid) were evaluated for their
potential to reduce the microbial load from the water in poultry farms. The disinfectants were
effective on normal as well as on lower than recommended doses. Glutralaldehyde containing
disinfectant had significantly higher efficacy. The study insinuates the continuous monitoring of the
water quality and use of suitable disinfectant in poultry environment for better microbial quality of

Recently, it was found that H2S donor NaHS alleviates the harmful effects of stress in plants.
Chromium is considered very harmful heavy metal for both plants and animals. A hydroponic
experiment was carried out to check the alleviating effects of NaHS in chromium stressed plants.
The treatments consisted of three H2S donor sodium hydrosulfide (NaHS) (0, 100 and 200 µM) and
two Cr (0 and 100 µM) levels. The results showed that H2S application increased plant growth and
photosynthesis slightly as compared to control. H2S alleviated the inhibition in plant growth and
photosynthesis by Cr stress, with higher H2S level having more beneficial effect. H2S also reduced
Cr concentration in all three plant parts, and higher H2S level had greater effect. Exogenous
application of NaHS alleviated cell disorders both in root and leaf cells. On the basis of these
results it may be concluded that H2S is a promising gas molecule, which can improve plant survival
under chromium stress.

Cadmium (Cd) interrupts many metabolic reactions and decreases the antioxidants enzymes as well
as damage the cell structure that cause growth retardation and ultimately plant death. The
ameliorating effects of 5-aminolevulinic acid (ALA) under cadmium (Cd) stress conditions were
studied with special attention being given to root morphology and root ultra-structure in oilseed
rape. The plants were treated hydroponically with three different Cd concentrations (0, 100, 500
μM) and foliar spray of ALA with three concentrations (0, 12.5 and 30 mg/l) simultaneously. After
15 days of treatment higher Cd stress significantly reduced the plant biomass and root morphology.
Moreover Cd increased the production of reactive oxygen species (ROS) resulted in enhance the
malondialdehyde (MDA) contents in the roots. Foliar application of ALA improved the plant
growth, root morphology and significantly reduced the ROS and MDA contents in roots under the
Cd stress conditions. On the other hand higher concentration of Cd (500 μM) decreased the
activities of antioxidants enzymes like catalase (CAT), superoxide dismutase (SOD), peroxidase
(POD) and glutathione reductase (GR) and also declined the oxidized glutathione (GSSG) and total
glutathione contents in roots. As well as Cd toxicity had no affect on total soluble protein (TSP),
ascorbic acid (ASA) contents and reduced/oxidized glutathione ratio (GSH/GSSG). Application of
ALA at 25 mg/l dosage significantly enhanced the antioxidant activities e.g. APX, SOD, POD, and
GSH contents. Cd toxicity damaged the whole root structure which was evident by electron
microscopic ultra-structures. Cell possessed the undeveloped nucleus and mitochondria, cracked
cell wall, occurrence of plasmolysis, and absence of endoplasmic reticulum under the higher
116
concentration of Cd (500 μM) alone. Whereas, ALA showed whole clear cell with developed
nucleus and nuclear membrane, smooth cell wall, continuous endoplasmic reticulum, and well
shaped mitochondria under the 500 μM cd level. These results suggests that, application of ALA
helped the plants to improve root growth, root antioxidants enzymes, and ultra-structural changes in
root tip cells under short term Cd-induced stress (15 days)

Due to its prolific growth, oilseed rape (Brassica napus L.) can be grown successfully for
phytoremediation of cadmium (Cd) contaminated soils. Nowadays, use of plant growth regulators
against heavy metals stress is one of the major objectives of researchers. The present study
evaluates the ameliorate effects of 5-aminolevulinic acid (ALA, 0, 0.4, 2 and 10 mg/l) on the
growth of oilseed rape (Brassica napus L. cv. ZS 758) seedlings under Cd stress (0, 100 and 500
μM). Results have shown that Cd stress hampered the seedling growth by decreasing the radical
and hypocotyls length, shoot and root biomass, chlorophyll content and antioxidants enzymes. On
the other hand Cd stress increased the level of malondialdehyde (MDA) and production of H2O2
and accumulation of Cd in the shoots. The microscopic study of leaf measophyll cells showed that
toxicity of Cd totally destroyed the whole cell structure and accumulation of Cd also appeared in
micrographs. Application of ALA at lower dosage (2 mg/l) enhanced the seedling growth and
biomass. The results showed that 2 mg/l ALA significantly improved chlorophyll content under Cd
stress and decreased the level of Cd contents in shoots. Application of ALA reduced the MDA and
H2O2 levels in the cotyledons. The antioxidants enzymes (ascorbate peroxidase, peroxidase,
catalase, glutathione reductase and superoxide dismutase) enhanced their activities significantly
with the application of 2 mg/l ALA under Cd stress. This study also indicated that higher dosage of
ALA (10 mg/l) imposed the negative effect on the growth of oilseed rape. Microscopic study
showed that application of ALA alleviated the toxic effects of Cd in the mesophyll cell and
117
improved the cell structure. Use of 2 mg/l ALA under 500 μM Cd was found to be more effective
and under this dosage cell structure was clear, with obvious cell wall and cell membrane as well as
a big nucleus which was found with well developed two or more nucleoli. Chloroplast was almost
round in shape and contained thylakoids membranes and grana but starch grains were not found in
chloroplast comparatively to other treatments. On the basis of our results we can conclude that
ALA has promotive effect which could improve plant survival under Cd stress.

Effective pollution remediation is need of the hour because huge quantities of heavy metals
including Zinc are being discharged from the industries which are contaminating soil and water
resources. Silicon is agronomically important fertilizer element that enhances plants tolerance of
multiple abiotic stresses. This study was designed to Investigate the effects of Zinc stress on
different physiological, morphological and biochemical properties of cotton plants and role of
silicon in alleviation of that detrimental effects of Zinc. Zinc (Zn) was introduced as two levels
zinc 50 µM and 25 µM and one level for Silicon 1mM and treatments were; Control, 1mM Si, 25
µM Zn, 25 µM Zn+ 1mM Si, 50 µM Zn, 50 µM Zn+ 1mM Si in nutrient solution while keeping pH
stabilized at 6 ± 0.1. Physiological, morphological and biochemical responses of cotton plant to
Zinc stress was observed after eight weeks and data regarding root/shoot length, root/shoot fresh
and dry weight, Leaf area, SPAD values, Chlorophyll a, chlorophyll b, total chlorophyll,
carotenoids, photosynthetic rate (A), transpiration rate (E), stomatal conductance (gs), Electrolyte
leakage values were recorded. Anti-oxidant enzymes activity such as Superoxide dismutase (SOD),
guaiacol peroxidase (POD), soluble protein and Zn contents in roots, stems and leaves were
determined. Statistical analysis was carried out using SPSS statistical package version 17.0. The
results suggested that the Zn considerably inhibited the overall growth parameters of the cotton
plants with increasing Zn concentration, decreased root, shoot and leaves weight, length. Highest
level of metal uptake was carried out by Zn50 roots, shoots and leaves 3604.5g Kg-1 DW, 1042.5g
Kg-1 DW and 653.14g Kg-1DW respectively. Overall chlorophyll status was severely damaged by
the Zn toxicity most affected by Zn50. Stress of Zn concentration affected the antioxidant and
118
enzymatic activity adversely and increased the production of the guaiacol Peroxidase (POD),
Superoxidase Dismutase (SOD) enormously while in mean time decreasing the contents of soluble
protein to greater extant, revealing the enhanced production of the Reactive Oxygen Species (ROS)
in response to the stress caused by the Zn. This enhancement in the production of the ROS caused
damage to protein and caused decrease in contents. Zinc on the other hand caused strong alleviation
of the toxic effects of the Zn stress and caused enhancement in the overall growth, anti-oxidant
activity and increased level of protein contents.

Azo dyes are widely used in the textile industry and can be hazardous to the environment due to
their reactivity, toxicity and recalcitrance. The degradation of acid red 66 in aqueous phase was
experimentally investigated using iron mesh titanium coated electrode with potential difference of
28V. The influence of the pH, supporting electrolyte concentration, concentration of dye and
configuration of electrodes on dye degradation was studied. The intermediate formed during the
degradation were detected by GC-MS. The maximum degradation (97 %) occurs at optimum pH 7
in the presence of 1.2 g electrolyte/L in 18 minutes. NaCl was found to be the most appropriate
electrolyte. Two anode one cathode system was found to be most working configuration of
electrodes during electrolytic process. Increase of the dye concentration required more time for
degradation. The results showed that the electrolytic degradation process is much beneficial over
the other oxidative/biodegradative processes.

Heavy metal pollution is of much environmental concern, and it poses major threat to terrestrial
plants, animal and human via food chain. Lead toxicity has gained a considerable attention as a
potent envirornmental toxicant.The present study was conducted to investigate the alleviation of
detrimental effects of lead by silicon nutrition in soil grown cotton plants . A wire house pot
experiment was carried out at a wire house of Government College University Faisalabad. Cotton
seeds of genotype MNH-886 were sown in earthen pots. After five weeks of sowing, four
treatments were applied, i) Controlled conditions (CK), ii) silicon (Si), iii) Lead (Pb),( iv)
Combined Silicon and lead (Pb 0.5 mM and Si1mM). Each treatment was applied to each pot after
every alternate day for five weeks by making solution in distilled water. After twelve weeks of
sowing plants were hearvested and growth variables including root shoot length; root shoot fresh
and dry weight were estimated. Leaf area and SPAD value was measured. For the determination of
electrolyte leakage of roots and leaves, EC was determined from leaves and root extract after one
day of hearvesting. The data was analyzed statistically by using standard procedure.

Azo compounds constitute the largest and the most diverse group of synthetic dyes and are widely
used in a number of industries such as textile, food, cosmetics and paper printing. Azo dyes are
ubiquitously used in the textile industry. These dyes need to be removed from the effluent prior to
discharge to sewage due to their intense color and toxicity. However, wastewater containing dyes is
very difficult to treat, since the dyes are recalcitrant organic molecules, resistant to aerobic
digestion, and are stable to light, heat and oxidizing agents due to their structure and molecular
size. Biological wastewater management is amongst the most significant biotechnological
techniques and a variety of bacterial species have been reported to decolorize azo dyes under
aerobic and anaerobic conditions. In this regard, this study was conducted to isolate bacterial strains
which had ability to decolorize the reactive yellow S3R. The strain RN34 was found to be efficient
in decolorizing reactive yellow S3R as it decolorized 88% of the reactive yellow S3R azo dye only
in 48 hours. This isolate was also found to efficiently decolorize reactive red S3R azo dye. Further
results indicated that this isolate showed optimal decolorization of the reactive yellow S3R azo dye
at pH 7.5 in the presence of yest extract as an additional nutrient source under static incubation at
300C. the decolorizing potential was found to considerably enhanced when it was co-cultured with
a reactive red S3R decolorizing isolate M41. It is noteworthy that when both the isolates were co-
cultured, they could also decolorize orange reactive and reactive GR black up to 51.17 and 37%,
respectively

A comparative study of removal of health risk organic dyes from water was carried out using
sorption and solublization. Activated carbon was used as sorbents to remove reactive textile dyes
from aqueous solutions. The bath sorption experiments were conducted at various pH, sorbent
dosage, contact time, initial concentration and agitation speed. The applicability of the Langmuir
and Freundlich isotherm models was examined. The influence of cationic surfactant, cetyltrimethyl
ammonium bromide (CTAB), and an anionic surfactant, Sodium dodecyl sulfate (SDS) on spectral
properties of selected dyes in aqueous solutions was investigated by means of UV-Visible
spectroscopy in submicellar and micellar concentration range. Absorption spectra of these dyes in
the presence of surfactant confirmed which type of interaction was taking place between molecules
of dye and surfactant. It was explored that initially molecules of dye were attached with monomeric
molecules of surfactant in premicellar region while in post micellar region they were
accommodated with in micelle. The values of micelle–water partition coefficient Kx, free energy of
partition, dye-surfactant binding constant Kb and free energy of binding were also calculated by
differential spectroscopic method.

Frequent use of phenylurea herbicide isoproturon (IPU) in agricultural fields has resulted not only
in the contamination of arable soils but also in the adaptation of the soil microflora to its rapid
biodegradation. Microbial biodegradation plays a key purifying role by governing natural
attenuation of pesticdes in the environment. In order to further elucidate the factors affecting the
purifying capabilities of soil microbial communities, we monitored the spatial variability of the IPU
mineralization activity of soil microflora over a three years (2008, 2009 and 2010) an agricultural
field cropped with winter wheat/ rapeseed/ barley crop rotation periodically exposed to this
herbicide. Thirty six soil samples were collected on a XX x YY m grid, analyzed by
radiorespirometery using 14
C-ring-labeled IPU. Several biological and physicochemical parameters
including pH, relative humidity, CEC, organic carbon, total nitrogen, C/N ratio, microbial C
biomass, culturable bacteria and mineralization activity were estimated. Significantly higher
cumulative IPU mineralization were observed in 2008 and 2010 when the field was treated with
IPU and sulfonylurea herbicides, respectively (p<0.05). Spatial variability of IPU mineralization
revealed higher variability in 2009 and 2010 as compared to that observed in 2008. Pearson’s
coefficient of correlation indicated for a weak relationship between the IPU mineralization and
several the physico-chemical properties like pH and organic matter content. However, the
geostatistical map of IPU mineralization rate (µm) showed important similarity with that of soil pH
and organic matter content. Furthermore, geostatistics revealed IPU and sulfonylurea herbicide
treatment lowered the range of variation in IPU mineralization activity. Based on these findings, we
conclude that pesticide treatment is the key driver of pesticide degrading ability of the soil
123
microflora and that soil physico-chemical parameters (pH and organic matter content) are
influencing the expression of the IPU degrading potential of the soil microbiota.

Azo dyes are widely used in textile industries and to date, various techniques, such as
adsorption, photocatalysis and purification by membrane filtration, have been reported to
remove this class of dye form wastewater. However, decolorization is not a correct solution.
Recently, various author reported the toxic and carcinogenic nature of dyes, which is
considered a threat to the aquatic life. The advanced oxidation process (AOP) has advantages
over all existing technologies due to its degradation and mineralization efficiency and allium
cepa test has been used for the evaluation of toxicity of treated sample. In present study, the
toxicity of dye aqueous solution was checked before AOP application, which was found to
toxic (up to 90% versus negative control). After toxicity evaluation, the aqueous solutions of
Yellow F3R were irradiated to UV (40 watt, 254 nm) in the presence of H2O2 and degradation
was evaluated using spectrophotometric analysis. The dye degradation was influenced by multi-
parameters like hydrogen peroxide percentage, time of UV irradiation, pH and shaking speed.
The experimental variables were optimized to obtain maximum dye degradation and the
toxicity of maximum degraded dye aqueous solutions were checked by allium cepa biological
test, which is considered a true representative of vast fana and flora community. The optimized
values of variable such as dye concentration, H2O2 percentage, UV irradiation time, pH and
shaking speed were found to be 100 ppm, 5%, 1 h, 3 and 100 rpm, respectively and the dye
solution treated at these selected level showed significantly reduced toxicity (up to 65%).
124
Results indicate that this method is useful for dye toxicity reduction and also applicable for the
toxicity reduction of true textile wastewater, which may be helpful for aquatic life.

Removal of toxic heavy metals from water channels is one of most significant environmental issue.
Response Surface Methodology (RSM) based optimized model was used to assess the potential of
Thespesia populenea as a feedstock material for the removal of Cr and Ni from the wastewater of
tannery and textile industry. Effects of operating variables such as pH, agitation time and dose
concentration were also determined for the removal of heavy metals ions followed by quality of
waste water obtained. Optimization of biosorption process using RSM model showed that the best
possible percent removal of heavy metal, 78.26 % and 86.52 % for Ni and Cr were obtained at 2
pH, (1.5 gL-1
) biomass doze concentration (with 0.710 mm particle size), 40 (min.) agitation time
and 2.81 pH, 0.91 (gL-1
) biomass doze concentration (with 0.250 mm particle size), 51.90 (min.)
agitation time; respectively. The percent removal theoretically predicted by quadratic polynomial
models was found to be in good agreement with those of experimental data, verifying the accuracy
of the proposed model. This study showed that use of indigenously available non-conventional
plant materials could be used as biosorbent to the accelerated problem of effluents treatment.

The term ―resistance bacteria‖ describes a number of bacteria that belong to different phylogenetic
groups but share the ability to grow on metal contaminated site and to accumulate extraordinarily
high amounts of heavy metals in their biomass without suffering normal metabolic functioning.
Two basic characters distinguish resistance from related non-resistance bacteria: a strongly
enhanced rate of heavy metal uptake and a greater ability to detoxify and sequester heavy metals.
An interesting come out that has come forth from comparative physiological and genomic studies
of resistance and non resistance bacteria reveals that resistance mechanism is because of different
regulation and expression of genes found in both kinds of bacteria in chromosomes and on plasmid.
Primarily, resistance in microorganisms can occur through the decreased uptake of metal ion, the
increased use of efflux pumps, biosorption, and the upregulation of genes associated with oxidative
stress response and in metal reduction. Heavy metal contaminated soils pose an increasing problem
to human and animal health. An overview of literature demonstrates the cleanup efforts using
bacteria to remediate specific metal effected soils have appeared over the last 30 years. Moreover,
metal resistant bacteria can be used for microbe assisted phytoremediation to restore the
productivity, fertility, and stability of heavy metal spoil, leading to the development of a
sustainable ecosystem.

Both essential and non-essential transition metal ions can be toxic to cells. The physiological range
for essential metals between deficiency and toxicity is extremely narrow. A tightly controlled metal
homeostasis network is required to adjust fluctuations in micronutrient availability in for all
organisms. One protective strategy against metal excess is the production of high affinity binding
proteins to inhibit uncontrolled binding of metal ions to physiologically important functional
groups. Phytochelatins (PCs) are heavy metal-binding peptides that play important roles in the
detoxification of toxic heavy metals. PCs are the cystine rich oligomers of glutathione having
variable chain length with basic formula is (-GluCys)n-Gly. The molecular weight ranges from
2000 to 10000 DA. In addition, a number of structural variants of PCs such as (γ-Glu-Cys)n-β-Ala,
(γ-Glu-Cys)n-Glu, (γ-GluCys)n-Ser and (γ-Glu-Cys)n, have been identified in some species of
plants. Phytochelatins also regulate intracellular concentrations of essential metals in eukaryotes,
including higher plants, fungi, and microalgae. Recently, PC synthase (PCS) genes are isolated
from Arabidopsis thaliana (AtPCS1), wheat (TaPCS1), Thlaspi caerulescens (TcMT3). PvPCS1
from Pteris vittata , Nelumbo nucifera (NnPCS1), Sesbania rostrata (SrPCS).The PC synthase is
novel papain-like Cys protease having combined protease and peptide polymerase capabilities with
self-regulated activity; it terminates the reaction as the activating metal ion is chelated by the
nascent PCs. Plants employ a two-step mechanism to detoxify toxic ions. First, phytochelatins bind
to the toxic ion, and then compartmentalization is the second step of conjugation in which metal-
phytochelatin complex is sequestered in the vacuole. The vacuole is generally considered to be the
main storage site for metal-phytochelatin complex in yeast and plant cells. Sequestrations of toxic
127
metal ions to vacuole is the main strategy for heavy metals/metalloids detoxification and tolerance
in plants because it prevents its free circulation, reduces the level of toxic metal ions in cytosol,
forces them into a limited area.
P-53 BACTERIAL ZINC HOMEOSTASIS

Zinc is essential to virtually all organisms since it plays important catalytic and structural roles in
many proteins but poses problems of toxicity in excess. Bacteria cell membranes prevent passive
diffusion of metal ions into the cytoplasm, tightly regulated systems are required to permit metal
ion uptake which allowing them to achieve effective zinc homeostasis under a range of zinc
regimes. Highly efficient zinc acquisition systems are used to scavenge zinc from the environment
under zinc-restricted conditions. In many cases, this involves direct transcriptional control of
metalloregulatory protein synthesis as well as post transcriptional regulation. There is evidence that
bacteria control their zinc requirements in response to zinc availability by down regulating the
expression of zinc proteins during zinc-restricted growth some of which utilize either ATP or the
chemiosmotic potential to drive the movement of Zinc across the cytosolic membrane, together
with proteins that facilitate the diffusion of this ion across either the outer or inner membranes of
prokaryotes. And finally, the expression of the zinc homeostatic machinery is subject to zinc-
dependent global control ensuring that zinc acquisition, storage and consumption are geared to zinc
availability and that intracellular levels of free zinc do not reach toxic levels.

Hydrogeological studies are the most important tool for the assessment of groundwater resources
and sustainability issues. Malir River Basin (MRB) that lies at the north east of the Karachi city is
popular for peri-urban agricultural activities with groundwater irrigation in its various parts. In this
study, aquifer characterization in terms of hydraulic conductivity and specific yield of different
sub-basins of the MRB catchment is carried out. Geological map (GSP, 2001), general topographic
(GT) sheets (SOP, 1998), electric resistivity survey and hydrogeological profiles (JICA, 1990),
vertical electrical sounding (VES) and records of drilled test hole (KWSB, 2005) are used for the
representation of the MRB aquifer system. The Geological Map of Karachi city was digitized with
the image processing software and georeferencing of the map was done to make it compatible with
GT sheets. The spot heights (around 200 points) and contours marked in the GT sheets were also
digitized to prepare the digital elevation model (ground surface/top elevation of layer) for the
MRB. Similarly, the bottom of aquifer is marked on the basis of hydrogeological profiles. The
refinement to the aquifer thickness and bottom of impermeable boundary is incorporated by the
records of electric resistivity survey and digitization of hydrogeological profiles carried out by
JICA (1990) and records of VES reported by KWSB (2005). The records of test holes drilled up to
the depth of 365m were also used to substantiate the thickness of saturated permeable material
within the MRB aquifer system. Two methods namely: pumping test analysis and porous medium
129
approach were adopted for the estimation of aquifer parameters (hydraulic conductivity and
specific yield). The pumping tests with observations of water levels recorded through piezometer
installed at 30m interval were conducted (KWSB, 2005) on five wells in the MRB. The pumping
test data was analyzed by type and field curve matching; and corresponding values of aquifer
parameters were calculated. Similarly the layered porous medium approach was applied on the
lithological logs of test hole drilled in the MRB for the estimation of aquifer parameters and ranges
of hydraulic conductivity and specific yield were estimated. Results of this study suggest presence
of an unconfined highly transmissive aquifer in the MRB having thickness varies from 200-400m
on the north western (upstream side) of the Area of Interest (AOI) and 17-200m within the AOI and
pinches out at south eastern boundary. The thickness of MRB aquifer decreases from northeast to
southwest direction with maximum and minimum values of 414m and 17m in the Khadeji and
Thaddo Basin respectively. The estimation of hydraulic conductivity and specific yield by porous
medium approach gives closer results to the values reported earlier (JICA, 1990) in comparison to
the pumping test data analysis which gives unrealistic values of the above aquifer parameters. The
ranges (minimum and maximum values) of aquifer parameters estimated by porous medium
approach for the sub basins can be used as an initial guess during groundwater model development
and calibration. The maximum and minimum values of hydraulic conductivity are estimated as
1.88m/d and 493.18m/d in the Thaddo Basin whereas the maximum and minimum values of
specific yield are found out as 0.09 and 0.17 in the Thaddo and Sukkan Basin respectively.
Additional hydrogeological investigations are suggested to be carried out especially in the northern
side of the MRB catchment area. Groundwater monitoring is also suggested to be undertaken on
long term basis for the characterization of MRB aquifer system.

There are various environmental changes which are accelerating worldwide, posing significant challenges
for humanity. These include energy crises, environmental degradation, environmental health, pollution,
ozone depletion, climatic change and land degradation. Climatic change and vegetation cover reduction lead
to catastrophic floods. This study was based on investigating the climatic variables (mean temperature &
precipitation) and vegetation cover change associated with extreme stream flow events (2010 Indus Floods)
in River Indus at Shatial Bridge, Kohistan. Two major types of data sets were used, satellite data and ground
data (hydro-meteorological data) respectively to accomplish the objectives of this study. Satellite datasets
used for the DEM (Digital Elevation Model) and land cover monitoring were ASTER V002 (Advanced
Space-borne Thermal Emission and Reflection Radiometer) and Landsat TM 4-5 (Land Remote Sensing
Satellite Thematic Mapper 4-5) respectively. The extreme River Indus events were analyzed using hydro
meteorological data. Hydrological data included data for monthly Indus River discharge from 1990-2010.
Meteorological data included monthly precipitation and mean temperature from 1990-2010. The results of
the study show that the enhanced Indus flow at Shatial Bridge during floods was mainly due to increase in
mean temperature that caused glacier melt and uneven monsoon rainfall distribution. Vegetation cover
seems to have no contribution in increasing the surface runoff during these flood periods.

Climate change and its impact on the design of buildings are currently subject to concern. Large
resources have been put into development of models for predicting future climate changes.
However, considering the huge investment in buildings combined with their expected long service
life, only few resources have been put into adaptation strategies for buildings. In line with other
countries, Bangladesh is at the beginning of developing a strategy to address the effect of climate
change on a broad scale. The present paper is based on one of the pre-studies for this work and
focuses only on the impact on the design of buildings. It is shown how performance requirements
for buildings may be taken as a starting point for a systematic evaluation of which climate related
data are needed as a background for the design of buildings. Among the conclusions is that the lack
of knowledge about the uncertainty of the relevant climate parameters is in itself a problem, and
that the building sector should be more active in presenting its need for knowledge about specific

Global agriculture is under significant pressure to meet the demands of rising populations using
limited soil and water resources that are predicted to be further stressed by the impact of climate
change. It could affect agriculture in several ways like productivity, agricultural practices,
environmental effects, agricultural land use, adaptation, etc. Rapid climate change could harm
agriculture in under developed countries like Pakistan, especially which are already suffering from
poor soil and climate conditions. Agriculture is the back bone of Pakistan’s economy that could be
heavily damaged by climate change. Under changing climatic conditions, growing period of some
crops (oilseeds, grains, etc.) may decrease and they are matured in less time. Horticultural crops
(such as tomato, onion, and fruit) are more sensitive towards environment and may heavily be
affected by climate change. The variabilities in climatic conditions may harmfully affect the crops
by causing increase in temperature and less availability of water for cultivation. A significant threat
posed by rising temperatures is water stress through increased rate of transpiration. Without
adequate rainfall or irrigation systems, crop failure is a real danger. These serious problems can be
tackled through the use of biotechnology. By using biotechnological procedures, it is possible to
create variability in the genome of crop plants followed by adaptation under changing climatic
conditions.

preview with high and diverse lofty mountainous terrain. The tribes of the area hitherto depend on
MPs to cure various diseases. During research, open-ended ad closed-ended interviews and
questionnaire form methodology was employed. This EMI reveals that 45 plants are of pertinent
significance because they are used not only at local level but also these MPs are exported to other
cities of Pakistan to manufacture drugs in pharmaceutical industries. In EMI some interesting
findings were use of Ajuga bacteosa in treating jaundice and in enlargement of liver and spleen.
The flowers of Achillea millefolium are used as laxative and tonic for brain and development of
secondary features in females. The root extract of Senecio chrysanthemoides is applied to treat
cholera and lung diseases in infants. The root of Berberis lycium is used frequently in treating
diabetes and spleenic troubles. The extract of Swertia petiolata is used in leucoderma and to prevent
vomiting of pregnancy. Arnebia bethemii is used to cure pneumonia, cardiac, tongue and throat
disorders. Angelica glavaca is useful in cancer/tumor treatment. Saussurea costus is used to cure
arthritis. Informant Consensus Factor (ICF) and Fidelity Level (FL) of medicinal plants were
determined. The category ―Fever, flu, cough and malaria‖ had highest ICF value (0.88) followed by
―Gastro-intestinal disorders, diarrhea, ulcers‖ had had ICF values (0.77), ranking at second position
which demonstrates high incidence of these types of diseases in the area. The medicinal plants with

Water plays a vital role in a country's economy. It has been critical to the making of human history.
Water is a main source of life and unfortunately, that source is becoming extinct in some parts of
the world and this case can be well observed in Pakistan. This document deals with the water crises
as well as its management in Pakistan. Pakistan is an agricultural country having a variety of
landscapes in its five provinces, Sindh, Balochistan, Sarhad, Punjab and Pukhtunistan with water
sources of five rivers Indus, Chenab, Ravi, Beas, Sutlej, Jhelum and also rain fall. In spite of these
resources, still there is scarcity of water for many purposes, even for the smooth running of daily
life. This resource is being depleted by direct or indirect effect of human activates as well as some
other environmental factors which are playing their havoc role. Now there is a need to improve and
manage the situation for the sake of avoidance from bad future and it can be done by creating
awareness among the people through different ways.Undesireable effects of environment can be
minimized by having a serious check and balance on human activities. The water crisis in Pakistan

―Nature is convenient standard that supports the existence of life with ups and downs ―by guarding
the veracity, diversity of nature and efficiently use of natural resources we can maintain the life on
planet. Global warming is the outcome of the mismanagement of micro and macro ecological and
social activates. The destruction of natural resources like, mangroves, dunes and coastal wetland
they protect us from storm, the intensity and frequency of floods is increasing day by day due to the
deforestation, greenhouse gasses emission is increasing in atmosphere with alarming rate.
Therefore, here is a dire need of good management (preventive, precautionary, proactive action).
Due to lack of long term policy Have to set the priorities through which we can preserve and
restore the natural resources because this natural resources provide economical development and

Cotton is a fiber crop which plays an important role in Pakistan’s economy. During the
past few years, the cotton plant has been adversely affected by drought which is also cited
as one of the most serious natural disaster under changing climatic conditions. Under
stress conditions, the gene expression of cotton plant can be up regulated and down
regulated and the level of expression also varies from plant to plant. It is important to
study the genes responsible for drought stress. Identification of such genes is a critical
step in this regard. The transcripts/genes responsible for drought stress can be identified
using bioinformatics tools. To identify the genes, sequences of known drought tolerant
genes of Arabidopsis thaliana and rice are retrieved, screened and classified. Then
identification of Expressed Sequence Tags (ESTs) is carried out. ESTs are rich source to
study and identify transcripts/genes responsible for various traits in plants and these
identified ESTs are subjected to multiple sequence alignment. The conserved domains and
motifs are predicted using bioinformatics online tools for further characterization.
Identification of drought related transcripts and there study at gene level is helpful to
understand the mechanism of drought tolerance in cotton plant. Gene identification
approach using bioinformatics is less laborious, need fewer resources and quick. Thus,
keeping all the above information in view, the strategy will be discussed to identify
drought tolerant transcripts/genes in crop plants.

The aim of this study was to ascertain WQI (Water Quality Index) of groundwater drawn from deep
aquifers with hand-pumps available to the communities settled in the surroundings of three important
tributaries of Kabul River. The main purpose of using WQI technique was to present the results and
complex water quality data in a simplified manner that is easier to interpret and understand by common
people. Present day, water from Kabul River is highly polluted due to direct introduction of effluents and
solid wastes from industries such as tanneries, sugar mills, paper industries and textiles. Earlier studies
have been carried out for assessing water quality of Kabul River. But the assessment of groundwater
quality in the low income communities in the vicinity of three tributaries of Kabul River namely Shah
Alam, Sardaryab and Budnai has become important and essential to be monitored after extreme floods that
hit Khyber Pakhtunkhwa, a province of Pakistan, in 2010 resulting from torrential monsoon. The most
serious impact of flooding in these areas was a wide spread contamination of groundwater which caused
serious health issues like diarrhea, cholera, typhoid, skin diseases, dysentery, infected liver, and
gastroenteritis. A total of fifteen wells used in this study were selected from five different villages
surrounding each tributary; based on their critical situation regarding severe damages in these villages by
floods and having no access to safe drinking water. Collected samples were analyzed by standard
techniques for 13 water quality parameters i.e. pH, electrical conductivity, total dissolved solids, total
suspended solids, total alkalinity, total hardness, chloride, sulfate, nitrate, calcium, magnesium, biological
oxygen demand and dissolved oxygen. In this study, according to WQI scale all the samples collected from
Shah Alam and Sardaryab comes under the condition of ―Unsuitable‖ indicating higher level of
contamination and have shown that water is highly risky for drinking and other domestic usages. Few
water samples from villages near Budnai River fall under the condition ―very poor‖ while others show
―Unsuitable‖ condition according to WQI scale. It is recommended that these poor communities with high
density of population should be provided with water filtration and purification plant on an immediate basis
141
to cope with the health issues and an alternate source of water should be arranged immediately not
allowing them to use this contaminated water.

Pakistan is among the countries severely-hit by climate change. Climate change is affecting plant
production by disturbing the optimum conditions for plant growth and development. Sudden
temperature rises during the grain filling stages of wheat, rice, and maize reduces grain formation.
This leads to yield reductions causing economic losses. In cotton, there is increased flower and
square shedding due to temperature rises. Extreme low temperatures, beyond the optimum range
for plant growth, also cause reduced plant survival and germination. Genomic approaches can help
to tag the genomic regions involved in plant adaptation to harsh climates. Post genome sequence
era has accelerated the genome annotation research identifying genes involved in abiotic stress
tolerance. DNA marker technology, a tool of modern genomics, can help to identify loci for harsh
environment tolerance and molecular breeding for release of crop cultivars best suited under post
climate change scenario. Association mapping and genomic selection are the recent versions of
genomic approaches which are promising to breed for plant abiotic stress tolerance under climate
change scenario.

The fungal diseases are the major problem in the production of crops. The crop production is
decreasing day by day due to fungal disease, especially in Asian countries. Rhizobacteria are
naturally occurring soil bacteria that aggressively colonize plant roots and benefit plants by
providing growth. These rhizobacteria can stimulate plant growth directly by producing growth
hormones or indirectly by producing antifungal compounds/antibiotics to suppress phytopathogenic
fungi. Rhizobacterial diversity is influenced by both plant and soil type. Since root exudation is
species-specific, it is a major factor that determines community composition within the rhizosphere.
We used different techniques like RAPD, 16srRNA for the assessement of genetic diversity of
antifungal rhizobacteria. Our results indicted a high degree of similarity in rhizobacteria habitating
in same region. Lastly the assessment of genetic diversity of antifungal rhiziobacteria can
contribute greatly in control of fungal disease and help in enhancement of crop production. The
major goal of our research is to overcome the stress due to which major crops of the Pakistan are
destroyed such as fungal diseases.

Pakistan being an agricultural economy is strongly relying on its water resources for generation of
revenue and sustainability of livelihood of its 60% population. The vast irrigation system of
Pakistan is constituted by the Indus River and its tributaries. The Indus River originates from the
mighty Hindukush- Karakoram-Himalaya range and enters into the northern areas of Pakistan
where it is fed by the snow melt of towering glaciers of Upper Indus Basin, thereby, serving as a
primary source for river discharge. Shigar River, a tributary of Indus River, lies in the Upper Indus
Basin and is dependent on the snow and glacial melt for availability of water. The river discharge is
found to be directly influenced by the change in % Snow Cover Area which is directly affected by
the temperature variation over the year. Any change in the rate of snow and glacial melt caused by
the climate variability may therefore influence the entire irrigation system of Indus River.

Emergence of industrialization and Urban sprawl are forceful factors to raise the graph of water
contamination and soil pollution. Faisalabad, the 2nd
large industrial city of the country is a source of
influx of several pollutants particularly heavy metals into urban environment. Undeniably, there is a
rising apprehension over the prospective for pollution of urban ground water with heavy metals. An
experimental work has been conducted to analyze the heavy metals Zn, Cu, Pb, Ni, As and Cd with
the help of ICP. In addition to these nutrients contents such as Na and K, were determined through
the flame photometer and Ca and Mg were determined through the buffer analysis in the urban
topsoil of sixteen selected solid waste sites and there were eight water samples collected around the
each solid waste site. A systematic sampling was done from the nearest distance of 10 meter to
maximum distance of 200 meter from the solid waste sites. The study was based on geospatial and
geo-statistical techniques along with laboratory work to assess the heavy metal contamination in
water. The study reveals that water present in the vicinity of dumping sites is not pure. Water
contains a large number of heavy metals which is very unsafe to human health. The mean
concentration of Zn, Cu, Ni and Pb ranged from 21.9-200.1, 12.03-109.85, 12.32-33.90 and 0.00-
30.25 mg/Kg respectively and K and Na mean concentration in the solid waste sites soil 1.357-3.50.
Some parameters exceeded from WHO standards like Cadmium, lead, Nickel. The concentration of
lead is high at five locations and of Ni has crossed the WHO tolerance level in every observed
ground water sample. Monitoring of water and soil contamination aspects is essential for the quality
assessment and sustainable development of the urban environment.

The meteorological data is considered as a key input to a dispersion model for performing
atmospheric dispersion modeling. Dispersion modeling plays an important role in accident and its
consequences analysis to assist in planning of evacuation and emergency preparedness plan in case
of an accident. To generate the meteorological data of a region where the observed station data is
not available, some meteorological models are used as the powerful modeling tools for this
purpose. The present study has been carried out to evaluate the simulative capability of a
meteorological model as Weather and Research Forecasting model (WRF). This model has been
used in present study for the simulation of the climatology of the region of Islamabad. The
Eulerian and grid dependent meteorological data for different parameters like ground temperature,
surface wind speed and wind direction so obtained were validated against the observed data of the
same region. The comparison of simulated and observed meteorological data of abovementioned
parameters indicated that the predicted results for the ground temperature seemed to have superior
agreement with the observed data of the same meteorological parameter while a slight mismatching
was observed for wind parameters. The reason was attributed to the large perturbation in wind
parameters as compared to the ground temperature. The overall performance of WRF model was
found satisfactory in simulation the climatology of the simulated region.

Over the last two decades, dengue fever has become a major mosquito borne disease in Pakistan.
Dengue outbreaks were reported in the major cities of Pakistan especially in Lahore where the
number of dengue cases increases radically in 2011 making it the worst epidemic disease in the
national history. This situation has emerged as a serious threat to public health and managing and
controlling risks of dengue outbreaks are being given a serious consideration by the concerned local
and provincial departments. It has been observed that dengue virus grows in specific climatic
conditions and there are some environmental factors (EFs) that promote its growth. The objective
of this paper is to propose an advance approach to identify the risk prone areas by linking these
factors with dengue outbreaks using satellite data and Geographical Information System (GIS)
techniques. The Remote Sensing (RS) and GIS techniques used in this study are proven to be more
efficient and cost effective as compared to the traditional approaches. Information provided in
terms of spatial and temporal distribution patterns of dengue fever outbreaks in Lahore and its
relationships with EFs are helpful in developing dengue risk maps. Assessment of dengue risk
maps based on EFs, investigates the dengue risk prone areas of Lahore. These maps will help
concerned departments in managing dengue outbreaks in a more informed and effective manner.
The EFs used for this study are Land Surface Temperature (LST), Normalized Difference
Vegetation Index (NDVI), precipitation, air temperature and humidity. The results show that most
of the cases occurred in residential areas near hospitals and those areas that have received heavy
rainfall followed by high NDVI and high temperatures.

productivity. Twenty rhizobacterial strains producing auxin and containaing 1-aminocyclopropane
1-carboxylate deaminase activity were isolated from the rhizosphere of the salt affected maize
plants. These isolates were screened for their growth promoting activity under axenic conditions at
1, 4, 8, 12 and 15 dS m-1
salinity levels. Results showed that increase in salinity level significantly
decreased the growth of maize seedlings. However inoculation with rhizobacterial strains reduced
this depression effect and improved the growth of maize seedlings at all salinity levels. The
selected strains significantly increased the root length, shoot length and fresh biomass up to 95%,
182% and 175% respectively. Among various rhizobacterial strains M4, M9, M14 and M20 were
the most effective strains for promoting the growth of maize at various salinity levels. The
relatively better salt tolerance of the inoculated plants was associated with the auxin production by
the rhizobacterial strains. Best Performing strains will be further verified for their growth
promoting ability in pot and field trials. Under current environmental scenario, the use of soil born
bacteria too mitigate soil salinity is a promising technique.

Freshwater resources might become the most limited resource in the future due to rising demands,
climate change, and the degradation of aquatic ecosystems. The fast increase of the population
leads towards the raised consumption water. According to the recent studies, Pakistan is in the
category of high degree stress. The water availability has been decreased to an estimated
approximated level that can adversely affect the humans. This is happening due the increase of the
urbanization and development. To understand the current situation, it was selected a small area of
Johar Town, Lahore, to assess the present situation on the water resource supply-demand balance
based. The research focused in the population trend estimate, the water demand, its increase trend
and finally the consumption rate. This research made our work substantial to realize the present
conditions and trends of water sustainability. The results elucidate demand of water per capita, in
parallel with, both, the new and old standards set forth by the Urban Unit development and
planning. The results and projections discussed were made on the basis of calculations in each
sector, since different sectors have different water demand values. It was calculated the ultimate
capacity for the selected area and forecasted the future demands of water. Water resources must be
carefully managed so it can lead to sustainable solutions for future generations. To promote a
comprehensive perspective on water sustainability for this particular case, it is recommended an
introduction of proper metering system by WASA, awareness to people; and communication
(conferences/seminars about water resources management). It’s not required planting more tube
wells. Moreover, rain water harvesting system should be commercialized so it is possible to store
rain water in abundance which can be used further for a consumption purpose. Furthermore,
pumping should be done according to available water conditions so that it is possible to avoid the
deterioration of land and affect the water level.

Global change in a broad sense — including climate and land-use change, as well as changes in
demographic structures in and between urban and rural societies — presents a number of
challenges to the concept of integrated resource management. Urban areas are the hot spots that
drive environmental change at multiple scales. Material demands and human consumption alter
biodiversity, hydro systems, land use, and waste discharge effects locally to globally. In this
process of global changes urban infrastructures are stressed due to the changing climate and
population pressure also. Growing population changes the face of cities by crowding them and
constructing them. In the pace of growth when our cities are becoming more urban, Green
Structures in all forms can play an important role by giving many services to environment and
community. Cities are and can be embedded with varieties of green structures to make it more
livable. Green Structures provide number of services for the population around. In sustainable
perspective, green structure is more than the sum of green spaces. It is considered as spatial
network of open spaces, public and private gardens and parks, sports fields, allotment gardens,
woodlands and recreational grounds. Therefore it is considered as a significant part of built up
environment and major source of ecological services. To structure urban areas for sustainable
environmental development, it is necessary to develop a proportion between grey and green areas.
The Research will discuss the impacts and importance of green structures in in changing urban
environment and analyze the ecological services generated from green structures. The research will
develop an approach of interrelation between green environment and urban society. Strategies will
be proposed for better land use planning in green and sustainable perspective. Cities themselves

Mediterranean farming systems and especially in Tunisia are inherently vulnerable to climate
change and market uncertainties. Therefore, technological and policy innovations will be needed to
increase their resilience. The objective of this study is to propose a set of adaptations strategies to
overcome climate change in the Low Valley of Medjerda Region. Adaptations strategies were
identified in interaction with farmers and local experts in the region and declined as scenarioswhich
are simulated with regional bio-economic-indicators model chain. Scenarios of adaptation
strategies included technological innovation based on the increasing of irrigation amounts for
already irrigated cropping systems (SIrr.am), the conversion to irrigated cereals (SIrr.c) for farming
systems dominated by rainfed cereals and the implementation of more efficient irrigation systems
for summer forages and vegetables (SIrr.sys). Each scenario was simulated with the current
preferential water tariff and the new binominal water tariff (NWT). The simulation results showed
that the adaptation strategies based on the introduction of alternative activities using more water
(SIrr.am scenario) increased the resilience of farming systems. Farming systems introduced these
strategies with different degrees: i) the farming systems with totally irrigated area intensify more by
increasing the irrigation amounts which increased crop yields and therefore farm profitability; ii)
however, the farming systems dominated with rainfed cereals were obliged in addition to the
intensification by increasing the irrigation amountsfor cropping systems with high added value
(vegetables), to adjust their cropping systems by reducingthe irrigated forage area and livestock to
ensure a minimum income and compensate the increasing of irrigation costs. The most appropriate
adaptation strategy for farming systems dominated with rainfed cereals and have totally irrigable
farmland was the conversion for the irrigated cereals (SIrr.c scenario) that allowed an extremely
increase of farm net margin. Mostly, farming systems did not invest in more efficient irrigation
system (SIrr.sys scenario) because that yields increasing due to the implementation of efficient
irrigation system did not compensate the investment costs. The introduction of the new binominal
water tariff (NWT) induced a decrease in irrigationunit cost and encouraged farmers to cultivate
irrigated cropping systems which allowed an increasing of the net margin for any farming systems
for all simulated technological innovation scenarios.

The prospect of global climatic changes is a matter of real public concern. In general, burning of
fossil fuels accumulates greenhouse gases and traps more heat which eventually cause global
warming. In these greenhouse gases, the emission of carbon dioxide has increased alarmingly since
industrialization age and humanity has visible impacts on the world's climate. Climate change can
be beneficial and as well as very dangerous for human health and socioeconomic systems. The
extreme emissions scenarios have extremely harmful effects. The threats are particularly acute for
poor and vulnerable communities in tropical and subtropical countries. Various major effects of
climate change include more hot climatic conditions, sea-level rise, and species extinction, wider
geographical range of tropical / subtropical diseases, crop zones migration possibility and increased
flooding. There are various technological options for mitigating CO2 emissions and concentrations
from the atmosphere. In which, carbon sequestration, alternate energy resources, switching to less
carbon intensive fuels and renewable energy sources are the important mitigation options. Carbon
Sequestration is a technology for reducing global warming of the environment by injecting CO2
into the subsurface for its long-term isolation from the atmosphere. Atmospheric CO2 can be
reduced by capturing emissions from power plants or chemical units and storing them into the
underground rocks and aquifers.

Hepatitis C virus is a major cause of chronic liver diseases which can lead to permanent liver damage,
hepatocellular carcinoma and death. The presently available treatment with interferon plus ribavirin, has
limited benefits due to adverse side effects and high cost. Hence, there is a need to develop anti-HCV
agents, which are less toxic, more efficacious and cost-effective. The present study was aimed at making a
sustained search for antiviral compounds and studies their therapeutic potential as anti-HCV drug. To this
end, in-vitro bioassay for screening the activity of test compounds was developed. One hundred and
seventy five phytochemicals were obtained from International centre for chemical and biological sciences
(ICCBS). Further, fourty herbs were collected from different parts of Pakistan on the basis of reports
(undocumented) of antiviral activity against different viral infections. Firstly, the effects of
phytochemicals/herb-extracts were studied on the cellular growth of liver and fibroblast cells.
Subsequently, HCV infected liver cells were treated with test compounds/herbal extract at non toxic doses
and replication of viral RNA was measured by Quantitative real time RT-PCR. For those compounds
which showed a positive response, we determined 50% inhibitory concentration (IC50). Three out of one
hundred seventy five compounds designated as 000, 010 and 043 showed antiviral effects in a dose-
dependent manner as well as synergism with interferon. Further, two out of twenty herbs exhibited activity
against HCV in our in-vitro assay. In order to identify the active ingredient, corresponding herbal extracts
were fractioned by thin layer chromatography (TLC), column chromatography and HPLC. Purified
fractions were tested for activity against HCV in in-vitro assays. Resultantly, we have identified three
active fractions against HCV. These in-vitro studies have identified six phytochemicals/herbal compounds
that show a potential of being antiviral agents against HCV and combination of these newly isolated
compounds with interferon may open new avenues of future HCV therapies.

livelihoods does not pay enough to the local placed indigenous knowledge of access to biological
diversity and applying the knowledge to land use practices. In eco-based societies, knowledgeable
persons or indigenous experts such as the Hakeem, Sanyasi, Perawana and nomadic tribes of a
village are recognized and respected by the society and actively participate in local medical
information education and decision making of indigenous medicine systems and productive
activities. Moreover, increasing acquisition of goods through access to and use of biological
resources, especially non-timber forest (NTFPs) and local agricultural products, has created a
system of Knowledge Power. This power has the capability of accessing resources and socially
influencing others within the local society. Sustainable livelihoods are functions of the interaction
between biodiversity (natural capital), indigenous knowledge (social capital) and enabling
environment (both policies and marketing forces). Indigenous knowledge includes cultural beliefs
and social values, cognitive learning process, knowledge transfer, technical knowledge for practice
and innovations, customary institutions for social consent and local governance. It is observed that
natural resources refer to the forest, rangeland, rivers, lakes and other kinds of natural endowments
that human societies’ livelihoods cannot sustained without; the term cultural resources refers to
traditional livelihood practices, place-and-time specific knowledge about their home land, cultural
beliefs and values, such as lakes, trees, shrines and mountains in the different sections of Islam,
perceptions of factors responsible for good harvest and good rain fall or natural disaster. More often
than not, the cultural resources viewed in public eyes are merely those which are commercially
marketable, that have easy market values for tourism development, such as singing, dancing,
costumes and exotic customs. The lessons learnt from development in the mountain region are that
the regions with unfavorable policy environment (such as resource sanction, block access to
biodiversity, suppressed or displaced cultural communities) usually often experience the poverty
and sometimes a degraded environment. On the other hand, loss of biodiversity cab lead to the loss
of cultural diversity, and therefore, further deteriorated local livelihood.

A major emphasis in bioengineering and medical technology is improved diagnostic techniques to
screen for disease. Such screening is required to identify illnesses, assess risk of disease onset, or
determine progression or improvement of disease state for diseases such as cancer, stroke,
Alzheimer’s, or cardiac disease. Nanotechnology may improve the sensitivity, selectivity, speed,
cost, and convenience of diagnosis. Individual biomolecular interactions can be detected by the
deflection of a microcantilever, the red-shifted emission of a gold nanoparticle, or the altered
conductance of a nanowire. Nanoscale labeling agents, such as quantum dots, have numerous
advantages to intracellular labeling and visualization. Nanotechnology has opened up the
possibility of other screening strategies as well. These techniques and others can be further
developed to enable enhanced visualization of an array, cell culture, or tumor; be multiplexed to
create smaller, denser gene and protein chips; or be integrated into a handheld nanofluidic device to
improve clinical diagnosis of disease.

Potential of microbial activities can be made more efficient by maintaining high bacterial
populations in the rhizospheric soil of plant. Use of enriched compost in the rhizosphere of plant
can provide a niche for bacteria to increase their growth and activities. Thus integrated use of
Rhizobium with plant growth promoting bacteria (PGPB) having trait ACC-deaminase plus P-
enriched compost (PEC) could be highly effective in promoting nodulation and yield of lentil crop.
A field study was conducted to evaluate the growth promoting potential of co-inoculation
Rhizobium with PGPB containing ACC-deaminase and PEC of lentil plants. Results of field study
showed that the integrated use of co-inoculation of R. leguminosarum with Pseudomonas Spp.
containing ACC-deaminase along PEC was highly effective and caused up to 73.5, 73.9, 74.4, 67.5,
73.3, 65.8, 40.5 and 52.5% increase in fresh biomass, grain yield, straw yield, pods per plant,
nodule per plant, nodule dry weight, 1000-grain weight and N content in grain of lentil respectively
as compared with respective control. It is concluded from the results that integrated use of R.
leguminosarum with Pseudomonas Spp. having trait ACC-deaminase plus PEC would be an
effective and novel approach for better nodulation which consequently improved yield of lentil

The concentration of lignin in plant tissue is a major factor controlling organic matter degradation
rates. Lignin and cellulose decomposition significantly increased at higher temperatures and
moisture contents. Lignocellulose decomposition depends on the association of biodegradable
cellulose and hemicellulose with lignin. Lignin is a recalcitrant material which hinders
cellulose degradation in conventional landfills. Because of this property of lignin cellulose to
lignin ratio (C/L) is a common landfill stabilization parameter. Refuse degradation in landfills is
a microbiological process and is highly dependent on temperature, moisture, and pH. Bioreactor
landfills are designed to enhance biodegradation of refuse by providing favorable conditions for
microorganisms. The thermal and biological study indicates that as lignin is solubilized, it breaks
down into lignin monomers, which can be converted easily by anaerobic bacteria into VFAs and
subsequently, methane. Experiments indicate that temperature is crucial to the degradation of lignin
compounds in a bioreactor landfill. Lignin, a valuable resource for chemicals and energy, is a main
component of wood, together with cellulose and hemicellulose. It is the second large source of
organic raw material, constituting about 4-35 wt% of most biomass, 16-25 wt% of hardwoods and
23-35 wt% of softwoods. Lignin decomposes slower, over a broader temperature range (200-500 °
C) than cellulose and the hemicellulose components of biomass.

Fungi are potential sources of diseases for human, animals and plants. The present research was
aimed to collect, isolate and identify different fungi to find out the prevalence of the mycoflora in
different habitats. Its economic importance and pathogenic toxicity was also measured and
documented. Air pollution is one of the most serious problems to human health. Air-borne fungal
spores were collected on two different culture media viz. potato dextrose agar (PDA) and water
agar (WA) from different habitats of Samahni forest areas (SFA), District Bhimber Azad Kashmir,
Pakistan. The soil and aqua mycoflora was also taken under consideration and its prevalence was
measured by using different techniques. Greater numbers of fungal colonies were obtained on PDA
than on WA culture medium. A total of thirty five different fungal species were investigated
belonging to eighteen different genera. The density of identified fungal species in each sample was
as: air mycoflora (AMF), soil mycoflora (SMF) and water mycoflora (WMF) were, 20, 32 and 11,
respectively. These differences could be due to geographical location, variable fungal growth
substrates in different samples as well as due to use of different sampling methods. A considerable
significant difference was seen among the fungal colony (%age) in AMF, SMF and WMF. It was
noted that soil mycoflora was more frequently depicted because land provides best environment
and nourishment for growth and reproduction of fungi. It was also observed that some fungi were
common in water and soil substrates which indicate that some species of soil fungi do use water as
mode of distribution and dispersal. The most dominant fungal species were Cladosporium
cladosporioides (7.1%) in Air, Fusarium oxysporum (4.9%) in soil and Fusarium oxysporum
(11.3%) in water samples.

Occupational health and safety issues are very frequent in almost every kind of industry. Faisalabad
is the 3rd
most populated and highly industrialised city of Pakistan. To evaluate the potential of
above mentioned issues in textile, food, rice mills and brick kiln sectors, one unit of each sector
was selected in Faisalabad as case study. For this purpose processing unit surveys were made and
questionnaires were distributed among employees. The pollution load on the environment due to
processing activities of these industrial units was also monitored with the help of several
instruments. It was found that ISO certified industries have better Occupational, Health and Safety
(OHS) conditions as compared to non-ISO certified industries. The results showed that flues gases
contained high concentrations of pollutants (especially NOx) due to burning of low quality of fuels
in industrial units. The concentrations of particulate matter within and outside the rice mills
industries were alarming. The opacity of smoke in brick kiln industry was higher than National
Environmental Quality Standards (NEQS). The values of humidity and illumination were observed
at disturbing level. It was found that working conditions at brick kilns were more unsuitable as
compared to other industries in Faisalabad but workers are obliged to work under these conditions
due to high unemployment rate in Pakistan. Finally, on the basis of existing conditions,
recommendations were made for each industry to reduce the health hazards.

Greenhouses plays an important role in agriculture and horticulture sector in Pakistan, therefore
cost effective and reliable power solution for greenhouses are very helpful in the growth and
expenditure of agriculture. However like most sectors in Pakistan, agriculture has not yet adopted
the full-fledge use of automation. Automation is the process control of industrial machinery and
processes. Efficient operation of such instruments requires an efficient supply of power. Most
regions of Pakistan lacks a continuous supply of power and hence are not able to use automation
and fruits of new technology in agriculture sector. One solution to overcome this problem is the use
of renewable energy resources. Solar energy is an efficient replacement for existing power solution,
which is available in abundance. This paper presents the design idea of PV-SOLAR system to
provide an economical energy system for automated greenhouses. Feasibility of the proposed
design is checked via HOMER software. Results have shown that the proposed system is efficient,
and cost effective as compared to proposed Hybrid-Solar/wind systems.

A field experiment was conducted to determine the affect of composts prepared from different
organic materials with rock phosphate (RP) on yield and P uptake of wheat crop at the research
farm of Agricultural University, Peshawar during Rabi 2010-2011. Wheat variety saran with a seed
rate of 100 kg ha-1 was grown in Randomized Complete Block Design (RCBD) with three
replications. There were 11 treatments, each of 3×5×2 m size. The row to row distance of wheat
plants was 25 cm. Composts prepared from RP fed FYM, simple FYM, organic waste and city
garbage were applied at the rate based of their P concentrations. Fertilizers were applied at the rate
of 120-90-60 kg ha-1 N, P and K, respectively in the form of urea, SSP or composts and K2SO4.
Nitrogen was applied in three split applications whereas all P and K were applied at sowing time.
Composts prepared from different organic materials with RP significantly (P ≤ 0.05) increased
grains, total dry matter, straw yield and 1000 grains weight of wheat over control. Significantly (P
≤ 0.05) increased grains yield of 5274 Kg ha-1, total dry matter yield of 8533 Kg ha-1, straw yield
of 3585 Kg ha-1 and thousand grains weight of 40.5 g of wheat were produced by the compost of
Organic Waste and half dose of SSP. Decreasing trend was observed in soil pH by the addition of
composts of different organic materials. Post harvest soil N and P concentrations improved with the
application of compost of organic materials. Significant (P ≤ 0.05) increases in N and P uptake by
wheat plants were found by the treatments of composts of different organic materials with RP.
Results suggest that the use of composts prepared from different organic materials with RP are

(from 45° S to 45° N). ERA-Interim-15 data was used as a boundary condition for the year 1998.
Five different simulations were performed with variation in the value of the Tiedke parameters e.g.
Default Tiedke, Entrpen, Cmtcape, Cprcon, and changes in trigger function. For the validations of
the simulation results, precipitation and temperature were compared with TRMM and CRU data.
The results show that Tiedke Scheme perform better than Grell scheme over Indian Ocean for
precipitation and changes in trigger function performs better than the others in Tiedke experiments.
However, changes in the value of parameters to make it half, Tiedke scheme is supposed to produce
more precipitation but the precipitation is decreased instead of increase. In addition for
precipitation in JJA Grell scheme show wet biases while Tiedke show dry biases and for
temperature Grell scheme show cold biases for both DJF and JJA while Tiedke show warm biases.
For the future work more simulation years are needed to better test Tiedke over RegT-band.

As time goes by, cultivation increased further. This led to a negative impact is real and very
influential to the environment if it is not finished, namely the impact of aquaculture waste. These
wastes contain toxic materials such as residual excretion amoniak, nitrite, and nitrate. To support
the sustainability of aquaculture is needed an eco-friendly solution with bioflok technology.
Bioflok technology is a technology which uses techniques enable the suspension derived from the
cultivation of waste (organic N such, ammonium, nitrite amoniak and nitrate) is then converted into
bioflok (collection of bacteria). This is composed of bacteria heterotrophic and bacteria
heterotrophic filaments, which use organic compounds as a source of carbons.This is one way that
waste management solutif and easily applied. Bioflok technology is done on the cultivation of fish
or shrimp or semi intensive intensive way of adding organic carbon as a substrate for doing aerobic
decomposition. Then given aeration and stirring the water to keep the high microbial flok in
circumstances remain suspended. Microbial flok this would be useful as feed flok shrimp or fish.
Thus, the handling of waste agriculture cultivation of prawns and fish is very useful for fish growth
and nutrient intake. Furthermore, this can continue to be developed flok until time desired while
maintaining carbohydrate composition for awarding the growth of bacteria. Advantages of
cultivation waste handling techniques include bioflok effective, efficient, and recovery. First,
effective in terms of handling waste cultivation itself. If the waste is directly dumped into the
environment, then it can threaten the balance of the ecosystem because it is malicious and
poisonous. With this technology, aquaculture waste into safe and can be used to feed. Second,
because this function efficiently bioflok key as a natural feed for shrimp or fish can reduce the cost
of feed and support the growth of organisms. Thirdly, recovery because bioflok also serves to
improve the water quality in pond aquaculture.

The industrial fixation of atmospheric nitrogen into urea is proving highly destructive to the
environment, both during its production and use. On an average, production of one kg of urea emits
2,500 grams of CO2, 10 grams of N2O and one gram of CH4 -all greenhouse gases. Seldom more
than 50% of applied N is taken up by crops and rest is either stored in soil or lost into the
environment. The nitrifying bacteria in soil convert chemical nitrogen into nitrate which is a
potential human health hazard in groundwater. The denitrifying bacteria in soil convert back the
nitrates into gaseous nitrogen and this phenomenon again releases greenhouse gases. Soil salinity is
an enormous world wide problem that hinders agricultural productivity and deteriorates soil quality
in Semi-arid climate. Salinity negatively affects nodulation in legumes. Plants under salinity stress
produce inhibitory levels of ethylene which may be repressed by using plant growth promoting
rhizobacteria (PGPR) containing ACC-deaminase. These PGPR, in combination with rhizobia,
have been reported to improve nodulation in legumes leading to increased nitrogen fixation. This
biological nitrogen fixation holds a huge potential to improve agricultural productivity along with
lessening the use of nitrogenous fertilizers thus decreasing the hazardous effects of chemical
fertilizers on environment. Pseudomonas and Rhizobium phaseoli strains were evaluated in pot and
field experiments under salt-affected conditions for their potential as biofertilizer to improve mung
bean productivity. Results showed that this biofertilizer significantly reduced the depressing effect
of salinity and increased nodulation and consequently nitrogen fixation thus improved growth,
yield and quality of mung bean. This biofertilizer also improved the ionic balance, chlorophyll
contents and physiological parameters of mung bean. The results suggested that this biotechnology
not only increased the mung bean productivity but also improved the environmental quality by
reduction in the use of nitrogenous fertilizers.

textile processing units are in operation in the surrounding of this city, which are releasing huge
quantity of wastewater contaminated with a variety of xenobiotics. Particularly, a substantial
amount of azo dyes are released continuously into wastewater streams in the surroundings of these
textile units. The discharge of these contaminants is considered a potential threat to environments
because of their hazardous nature. Thus, this study was undertaken to isolate bacteria possessing
high potential to degrade these azo dyes from the wastewater discharged by the textile units. The
wastewater samples were collected from the outlets of a number of textile units for the isolation of
azo dye degrading bacteria. A total of 40 bacterial strains were isolated from these wastewater
samples using minimal salt medium spiked with dye (Red C4BLN) and yeast extract. Selection of
azo dye degrading bacteria was done on the basis of decolorizing zone around their colonies. Out of
these five bacterial strains (S1, S5, S6, S29, S35) were more effective in decolorization of Red
C4BLN and they were used for further study. Above 90% decolorization of 100 mg L-1
of Reactive

Water is needed for food preparation, drinking, washing, and irrigation as well as used in industrial
processes. Water is neutral, tasteless, odorless and preferably of known hardness. The water
provided to the assessors for rinsing their mouths shall be identical with that used to prepare the
dilutions. But water is not tasteless to subjects (Bartoshuk, 1974). The objectives of the current
study were to investigate the water quality of two main sources of drinking water in Rawlpindi i.e.
from filtration plants and WASA supply water through physico-chemical analysis and to do a
comparative study of both according to WHO standards. Water quality parameters including
Conductivity (micro-S/cm), Total Dissolved Solids (mg/L), Turbidity (NTU), Arsenic (ppb),
Chloride (mg/L), Sulfate (mg/L) and Flouride (mg/L) were analyzed in the laboratory by using
standard method by APHA, 2005. It was broadly observed that pH value for Filteration Plants
samples was comparatively higher than WASA tubewells. The color and taste of both WASA
tubewells and filtration plants was clear and unobjectionable. The maximum turbidity value
1.21±0.42 NTU was observed in sample collected from tubewell (T.W.29) of WASA but no
turbidity was observed in filtration plants. The average chloride’s value observed in samples
collected from WASA tubewells was higher than chlorides level observed in filtration plants. The
maximum fluorides value 1.73±0.25 mg/l was observed in sample collected from tubewell (T.W.1)
of WASA but the maximum fluorides value 0.51±0.1 mg/l was observed in filtration plant (F.P.47)
of RCB. Similarly conductivity of tubewells water was higher that water taken from filtration
plants. The level of arsenic observed in WASA tubewell was almost double the arsenic value
observed in filtration plants water samplings. The maximum sulfates value 156±25 mg/l was
observed in sample collected from tubewell (T.W.6) of WASA but the maximum sulfates value
68±11 mg/l was observed in filtration plant (F.P.55) of RCB, which was comparatively low than
WASA tubewells. Most of the drinking water samples collected from WASA tubewells and
filtration plants of RCB, CCB, WASA and TMA in Rawalpindi were found to be fit for

Environmental pollution is a major problem associated with rapid industrialization, urbanization and rise in living
standards of people in Pakistan. With increasing demand of raw materials for industrial production, the non-
renewable resources are deteriorating at a rapid rate. Therefore, efforts are to be made for controlling pollution
arising from the disposal of wastes by conversion of these unwanted wastes into utilizable raw materials for
various beneficial uses. The main solid waste contributor industries are steel and blast furnace, brine mud, copper
slag, Fly ash, kiln dust, lime sludge, mica scraper waste, phosphogypsum, red mud/ bauxite, iron tailing, textile,
sugar cane, tanneries and lime stone waste. The different technologies for recovering useful energy from industrial
solid wastes exist. It is necessary for the success of these technologies to develop an Integrated Waste
Management System, coupled with necessary legislative and control measures. Energy can be recovered from the
organic fraction of waste (biodegradable as well as non-biodegradable) through two methods as follows: Thermo-
chemical conversion involves thermal de-composition of organic matter to produce either heat energy or fuel oil or
gas; Bio-chemical conversion is based on enzymatic decomposition of organic matter by microbial action to
produce methane gas or alcohol. In general, 100 tones of solid waste with 50-60% organic matter can generate
about 1- 1.5 mega watt power (MWP), depending upon the waste characteristics. The waste-to-energy facilities
can effectively bridge the gap between waste recycling, composting and landfilling, for tackling the increasing
problems of waste disposal in the urban areas, in an environmentally compassionate manner, besides boosting
power generation in the country.

Effects of wheat seed priming with chitosan on seed germination and biochemistry were investigated.
Seed treatments included hydropriming (water soaking) and chitosan priming i.e. soaking seeds in
aerated solution of 0.1, 0.25 and 0.50 % chitosan for 8 h. Chitosan priming improved the final
germination percent, germination energy, germination index, germination rate, vigor index and
shoot as well as root length of seedlings while shorten the mean germination time. Hydropriming
induced less prominent effects on seed germination and growth attributes as induced by chitosan
priming. Chitosan priming induced changes in the seed biochemistry were also investigated.
Catalase (CAT), superoxide dismutase (SOD), peroxidase (POD), protease activities and soluble
proteins increased in the chitosan primed seeds as compared to non primed control. The reducing
and total sugars decreased while non reducing sugars increased in chitosan primed seeds. Among
seed reserve mobilizing enzymes, α-amylase, α- naphthyl acetate esterase (0.25 % and 0.50%
chitosan) and β-naphthyl acetate esterase (0.50 % chitosan) activities increased in the chitosan
primed seeds. Hydropriming decreased the SOD, α- naphthyl acetate esterase, MDA content, non-
reducing and total sugars while raised the CAT, POD, soluble proteins, proteases in the seeds. In
general, hydropriming induced modulations in seed biochemical processes were different and less
prominent as induced by chitosan priming. Collectively, enhanced capacity of primed seeds to
scavenge free radicals by elevated antioxidants i.e. SOD, CAT and POD and rapid mobilization of
stored carbohydrates, proteins and lipids by amylases, proteases and esterases during seed
germination explained the beneficial effects of chitosan priming.

Biosorption are among these methods. Biosorption is a cost effective method. Cadmium (Cd) has
been identified an important heavy metal in Pakistan. The present short-term laboratory microcosm
study is designed to explore the potential of corn cob as bioresource, in three forms i.e. raw
biomass, ashed biomass and biochar biomass, to remove Cd from aqueous solutions. The
experiment was performed in leaching columns packed with different forms of biomass derived
from corn cobs. For sorption potential, solutions containing 0, 1, 5, 10, 50 and 100 mg/L Cd were
used. The sorption leachate samples was analysed for pH, EC, soluble organic carbon (SOC) and
total Cd. The study showed that corn biosmass both raw and ashed has a strong potential to remove
Cd from aqueous solution.

Nuclear energy is a form of energy produced by an atomic reaction, capable of producing an alternative source of
energy to that supplied by oil, gas or coal. Nuclear energy originates from the splitting of uranium atom in a
process called fission which can be used to generate heat for producing steam for running a turbine to produce
electricity. Nuclear energy can be used for both, destructive as well as for constructive purposes; however, the
world needs nuclear energy and will need it more in the years to come. Besides to produce electricity from the use
of nuclear power plants, nuclear energy has also been used widely in agriculture, medicine, industry, biology and
hydrology. The principal risks associated with nuclear power arise from health effects of radiation. At present,
power is produced from atom in advanced countries whereas other countries are also making efforts to produce
electricity at cheap rates from atomic power plants. Pakistan is the 6th most populous country of the world where
peak demand of electricity is 14,792 MW with installed capacity of 19,540 MW. Electricity generation of our
country is 85.6 TWh and consumption is 45% in household sector, 30% in industrial sector and 25% in others.
Pakistan has a small nuclear power generation program, with 725 MWe capacity, but there are strategic potential
to increase this substantially. The Pakistan Atomic Energy Commission (PAEC) is responsible for all nuclear
energy and research applications in the country. Its first nuclear power reactor is a small 137 MWe (125 MWe net)
Canadian Pressurized Heavy Water Reactor (PHWR) which was started in 1971 and which is under international
safeguards - KANUPP near Karachi. The second unit, at Chashma-1 in north Punjab, has been reported to cost
PKR 51.46 billion (US$ 860 million, with $350 million of this financed by China). A safeguards agreement with
IAEA was signed in 2006 and grid connection was made in March 2011, with commercial operation in May. In
2005, an Energy Security Plan was adopted by the government, calling for a huge increase in generating capacity
to more than 160,000 MWe by 2030. It included intention of lifting nuclear capacity to 8800 MWe, 900 MWe of
this by 2015 and a further 1500 MWe by 2020. Pakistan is a Member of International Atomic Energy Agency
(IAEA), World Association of Nuclear Operators (WANO), Candu Owner’s Group (COG), World Nuclear
Association (WNA). The number of visits by the Delegations/Missions/Teams of these Organizations to the
Nuclear Power Plants of Pakistan and related facilities over the decades is innumerable. Pakistan has no need of
furthering its defense capabilities through civilian nuclear facilities.

P-105 THE CHALLENGE OF WATER MANAGEMENT FOR IRRIGATION IN ARID
REGIONS

The demand for water is constantly increasing as a result of population growth and the expansion of
agriculture and industry. Agriculture commands more water than any other activity on this planet.
Although the total amount of water made available by the hydrologic cycle is enough to provide the
world’s current population with adequate freshwater, most of this water is concentrated in specific
regions, leaving other areas water-deficient. Fresh water resources are limited in the arid and semi-
arid areas whereas the existing water resources are often overused and misused. The lack of water
management in the arid areas generated numerous economic, social and ecological issues.
Agriculture currently accounts for nearly 70-80% of water consumption in the developing
countries. Because of the uneven distribution of water resources and population densities
worldwide, water demands already exceed supplies in nearly 80 countries with more than 40%
population of the world. Consequent to future population increase in developing countries, supplies
of good-quality irrigation water will further decrease due to increased municipal–industrial–
agricultural competition. These facts reveal that the time has come for the sustainable management
of available water resources based on global, regional, and site-specific strategic options:
improvement in current efficiencies of agricultural water use and conservation, both in the rain-fed
and irrigated agriculture, i.e. to produce more with the existing resources with minimum
deterioration of land and water resources; use of efficient, economic, and environmentally
acceptable methods for the amelioration of polluted waters and degraded soils, and re-use of saline
and/or sodic drainage waters via cyclic, blended, or sequential strategies for crop production
systems, wherever possible and practical. We believe that these strategies will serve as pillars of
integrated agricultural water management and their suitable combinations will be the key to future
agricultural and economic growth, particularly in regions that are deficient in freshwater supplies
and are expected to become more deficient in future. The productivity of water use in agriculture
needs to enhance in order both to avoid exacerbating the water crisis and to prevent considerable
food shortages. More efficient use of existing water resources could prove to be the effective tool
for the development of agriculture in arid and semiarid areas. This would provide new
opportunities for food security and sound environment in water scarced areas.

Crop residue is the part of plant left in the field after the crop has been harvested. Since Green Revolution
in 1960 and mechanization in agriculture, crop production has dramatically increased. Consequently, a
large amount of crop residue is produced worldwide and management of this huge amount is a challenging
problem. Major crops that produce large amount of residue are maize, wheat, sugarcane and rice. Due to
high C/N ratio and silica content, rice residue is unsuitable for animal feed. To manage rice residue, farmer
often burn the residue in the field posing a potential threat for environmental pollution. However, the
residue could be incorporated into soils or left on the surface as alternative management practices. This
study aims to investigate the effects of rice residue management on soil physical, chemical and biological
properties. A microcosm study will be conducted at Nuclear Institute for Agriculture and Biology (NIAB),
Faisalabad. The changes in soil biogeochemical parameters like pH, EC, soil organic matter (SOM), water
extractable carbon, microbial biomass carbon, microbial biomass nitrogen,, total nitrogen , total carbon,

Climate change refers to a statically significant variation in either the mean state of the climate or
in its variability and persistence for an extended period and is due either to natural processes,
external forcing, or to persistent anthropogenic changes in the composition of the atmosphere or in-
land use. Visible components of climate change includes 1) extreme of temperature, 2) drought, 3)
unprecedented floods and rainfall, & 4) high frequency of tropical cyclones. All these changes have
proven to affect food security: which exist when all people, at all times, have physical and
economic access to sufficient, safe and nutritious food to meet their dietary needs and food
preferences for an active and healthy life. It has four dimensions including 1) food availability 2)
access to food 3) stability of supplies and 4) healthy food utilization. All these dimensions will be
affected differently in the world. The most vulnerable region would be those already most
vulnerable to food insecurity and malnutrition such as Sub-Saharan Africa. The most vulnerable
Ecosystem would be tundra, boreal forests, mountains, and Mediterranean regions. The most
vulnerable population would be human being as since 1970-2000, 160,000 deaths and 5 millions
disability-adjusted life years have caused from only Malaria, Diarrhea, Malnutrition and flooding.
The most vulnerable gender would be the women and children especially those living in the rural
areas of the developing countries and are dependent upon subsistence farming. These women lake
modern fuel and power source for farming. The water shortage will add more to their food
insecurity and would thus increase the women work level. Climate change however presents some
opportunities as well. This presentation will thus explain the current situations and some future
remedies that may help mitigating the adverse effects of climate change.

Factors like increased prices, rising inflation, diminishing resources and intense global demand for energy
have led to an era of an era of energy shortage, especially in developing countries like Pakistan. Pakistan
spends ca. 7 billion US dollars on import of fossil fuel annually to fulfill its energy needs. The renewable
and sustainable energy resources are the best substitute to conventional fuel and energy sources. Biogas is
a potential energy source for Pakistan. Biogas produced by anaerobic digestion or fermentation of
biodegradable materials such as biomass, manure, sewage, municipal waste and green waste. Biogas
contain gases including CH4 (50-75%), CO2 (25-50%), N2 (0-10%) and H2S (0-3%). Biogas is an ideal
form of energy because it turns waste material into a source of power. The manure of cattle, in particular,
contains a high amount of biogas. Biogas contains substantial amounts of methane that makes it be used in
power appliance that run on natural gas. Pakistan has huge population living in rural areas. According to
estimates, animal rearing in rural areas of Pakistan produce 652 million kg of manure daily which can be
used to generate 16.3 million cubic meter biogas per day and 21 million ton of biofertilizer per year; the
latter is essential requirement for sustainable development of agriculture land. A high quality biogas plant
need minimum maintenance cost and can produce gas for 15-20 years without major problems and
reinvestment. Biogas is a best way of get rid off animal waste material. The energy it produces is clean and
powerful which does not pollute groundwater or air and quite safe. In addition, Pakistan can also explore
biogas potential of citrus pulp, paper industry, slaughter house and street waste. Poultry waste is also
considered and ideal base material for biogas production. According to a survey, Pakistan has capacity to
generate over 2000MW renewable energy from biogas. In Pakistan, the Rural Support Programme
Network is running the Pakistan Domestic Biogas Programme which has installed over 1500 biogas plants
and aims to develop biogas sector intensively around the country. Recently, around 4000 biogas plants
have been installed across the country. Practically, installing biogas units could help us to overcome
energy crisis in our country. They are low cost and can be run with small budget. Biogas corridors can
work as a good substitute for nearly 70% of country population residing in rural areas. However, the need
of national policy is imperative to bring this technology further at farmer doorstep.

Lead and cadmium are the common environmental heavy metal pollutants with a widespread
distribution. Both natural and anthropogenic sources including mining, smelting, and other
industrial processes are responsible for human and animal exposure. These pollutants often act as
copollutants leading to concurrent exposure to living beings and resultant synergistic deleterious
health effects. Overproduction of reactive oxygen species and free radicals beyond the cell’s
intrinsic capacity leads to a state of oxidative stress and resultant damage of lipids, protein, and
DNA. In the first part of this study, human blood samples from lead exposed and control males
were collected and different biochemical tests were performed on sera by using kits. The results
indicated an increase in glucose concentration in lead exposed subjects. There was an increased
concentration of LDL cholesterol, triglycerides, albumin, alanine aminotransferase, aspartate
aminotransferase and total oxidant status in the blood serum of lead exposed subjects. A decreased
concentration was noted for HDL cholesterol, total proteins and globulin. The concentration of
triiodothyronine (T3) remained almost the same in lead exposed and control subjects indicating no
effect of lead intoxication on triiodothyronine level in them. Lead concentration was determined
from serum of lead exposed and control subjects by Atomic Absorption Spectrophotometer.
Structure prediction including primary, secondary and tertiary structure of an enzyme delta-
aminolevulinic acid dehydratase (ALAD), which is sensitive to lead toxicity, was carried out by
using bioinformatics tools. A software and web database was also developed for evaluation of
results. As second part of the study, a database and website related to cadmium induced oxidative
stress were developed containing information of all metabolic dysfunctions that are associated with
cadmium toxicity and cadmium elevation using data of the patients that includes different physical
and biochemical parameters. These parameters are affected by the cadmium quantity. The website
comprises information regarding diagnosis of cadmium affected patients, treatment and preventive
measures to avoid cadmium exposure.

Untreated discharge of chromium, in water resources subsequently had serious environmental and
health effect. Among all the available techniques of metal reduction, biotic treatment is getting
attention for being environmental friendly and cheap that could be used to clean up metal
contamination wastewater. The 300 colonies were screened from initial level on chromium
amended NA medium. 26 pure colonies were selected in the secondary screening from wastewater.
All isolated strains are resistance to the Cr but there tolerance level was varied. The bacteria
isolated from specific Cr contaminated site like tannery effluent exhibit more resistant i.e. the
CrR11, CrR16, CrR21 showed MIC of 70 ppm while the strains CrR19, CrR4 show least MIC. The
strain CrR7, CrR21 was most resistance and fast growers then other bacterial strains. The
biosorption potential of the isolated strains was showed that these bacteria posses effective metal
sorption efficiency within a short time of treatment process. The highest reduction at 70 ppm was
shown by the CrR11 by 91%, CrR16 by 86%, CrR21 by 92%, CrR 7 by 82% in 24 hours at pH of 7
and temp was 30oC. Physicochemical parameters like pH, TDS, TSS, EC and Temperature of
effluents measured by standard methods. The pH of waste water samples were in the range of 6.0-
7.4 which was within the limits of the NEQS (6-10 pH). Total Dissolved solids (TDS) and Total
suspended solids (TSS) in the effluent varied form 490- 550 mg/l and 61 – 73 mg/l and
respectively. The values of TDS and TSS were below the NEQS recommendations. The highest
value of EC was found in S7 while least is found in S5 sample. The temperature of S3, S4, S7
effluent samples was found above the NEQS (40oC) guidelines for industrial effluents.

Potential of microbial activities can be made more efficient by maintaining high bacterial
populations in the rhizospheric soil of plant. Use of enriched compost in the rhizosphere of plant
can provide a niche for bacteria to increase their growth and activities. Thus integrated use of
Rhizobium with plant growth promoting bacteria (PGPB) having trait ACC-deaminase plus P-
enriched compost (PEC) could be highly effective in promoting nodulation and yield of lentil crop.
A field study was conducted to evaluate the growth promoting potential of co-inoculation
Rhizobium with PGPB containing ACC-deaminase and PEC of lentil plants. Results of field study
showed that the integrated use of co-inoculation of R. leguminosarum with Pseudomonas Spp.
containing ACC-deaminase along PEC was highly effective and caused up to 73.5, 73.9, 74.4, 67.5,
73.3, 65.8, 40.5 and 52.5% increase in fresh biomass, grain yield, straw yield, pods per plant,
nodule per plant, nodule dry weight, 1000-grain weight and N content in grain of lentil respectively
as compared with respective control. It is concluded from the results that integrated use of R.
leguminosarum with Pseudomonas Spp. having trait ACC-deaminase plus PEC would be an
effective and novel approach for better nodulation which consequently improved yield of lentil

Maize is third most important cereal crop of Pakistan. At optimum level, plant hormones play a vital role
in regulating plant growth. Auxin is one of the five most important plant hormones which affect many
aspects of plant growth and development. Rhizospheric bacteria have the ability to produce auxin and
improve the plant growth. The present study was conducted to estimate the impact of soil microbes that
synthesize plant hormone, especially auxin, in maize crop under field conditions. For the reason, various
auxin producing strains were collected and tested as sole or in dual combinations in the presence and
absence of L-TRP following randomized complete block design (RCBD) based on two factors factorial
arrangement and three repeats. The results determined a significant increase in plant height, fresh biomass
of plants, number of grains per cob, 1000 grain weight and straw yield due to dual inoculation with
M6+M7 over single inoculated and un-inoculated control in both, absence and presence of L-TRP.
Nutrient uptake by plants was also remarkably prominent in M6+M7 inoculaton over un-inoculated
control. Net photosynthesis, transpiration, stomatal conductance and water use efficiency was also
improved in dual inoculation of M6+M7. It is concluded that dual inoculation with auxin producing soil
microbes along with L-TRP could perform better than single or un-inoculated control.

In order to address climate change and green house gas (GHG) emission, the Kyoto Protocol was adopted
on 11 December 1997 in Kyoto, Japan. It was an important and necessary step toward protecting the global
environment which evidenced the most recent international effort to address the greenhouse effect. The
Kyoto Protocol was an agreement among the industrialized nations of the world to reduce emissions of six
greenhouse gases over a certain period of time. U.S., the European Union, Canada, and Japan and almost
170 other nations have signed this treaty. The Kyoto Protocol tackles emissions of six greenhouse gases
included carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydro fluorocarbons (HFCs), per
fluorocarbons (PFCs) and sulphur hexafluoride (SF6).The States which were members of the EU before
2004 must collectively reduce their greenhouse gas emissions by 8% between 2008 and 2012. Member
States which joined the EU after that date undertake to reduce their emissions by 8%, with the exception of
Poland and Hungary. Under Kyoto, industrialized nations pledged to cut their yearly emissions of carbon,
as measured in six greenhouse gases, by varying amounts, averaging 5.2%, by 2012 as compared to 1990.
However, the protocol didn't become international law until more than halfway through the 1990–2012
periods. By that point, global emissions had risen substantially. Initially, the U.S. withdrawal from the
Kyoto Protocol was considered its death knell. The agreement can only enter into force internationally if it
is ratified by at least 55 nations that, together, accounted for at least 55% of the total carbon dioxide
emissions in 1990. Given that the U.S. alone was responsible for about 25% of the 1990 carbon dioxide
emissions, experts predicted that without the participation of the U.S., the Kyoto Protocol would never be
implemented. However, in July 2001, the European Union, Japan, Canada, Russia, Australia, and 170 other
nations reached an agreement to proceed with the treaty.

The study was conducted in and around Ayubia National Park (ANP) to assess and analyze the
influence of poverty and population pressure on natural resources (forest, wildlife, medicinal plants
and pastures). Furthermore, it was intended to study the role of various governmental and non-
governmental organizations in natural resource management and their impact on the habitat of the
area. The data was collected by the several methods from the local community and NGO’S such as;
through observation and participation, Group discussion and in -depth interviews, questionnaire and
schedule. ANP is surrounded by 12 villages with a total population (65686). The people of the area
are mostly poor and poverty leads to the extensive use of natural resources. About 80-85% people
of the area are completely dependent on the forest and other natural resources of the area.
Population of the area is increasing rapidly like other parts of the country. Excessive collection of
Fuel wood (10.3 tons/hh/yr) was the major issue of the area and fuel wood collected from the forest
was the main source of energy in ANP, while agriculture crops and livestock were the sources of
food. Deforestation was the major problem of the area. Mostly people of the area are poor therefore;
they over-exploited the natural resources available to them for fulfilling their needs regardless of the
future consequences. The underlying causes found responsible for over exploitation of natural
resources were: poverty, increasing population (2.3%), lack of alternative sources of fuel and
energy, lack of environmental awareness, low literacy rate and weak administration on part of the
government pertaining to proper management of natural resources/forest and pasture resources of
the study area. Hence, it is concluded that poverty can be reduced through employment of local
population, encouraging private nurseries, bee keeping and poultry farming. Public awareness
through various sources like Ngo’s and media groups will certainly help in the population control
and conservation of natural resources.

Synthetic dyes are widely used in many industries such as leather, paper, textile, etc. to
impart colour to the desired products. On exposure to environmental conditions, the effluent
discharge of these industries containing dye molecules pose a potential threat to living
organisms. Among advanced oxidation processes, oxidation using Fenton's reagent is an
attractive treatment for the effective decolourization and degradation of dye because of its
low cost and the lack of toxicity of the reagents (i.e., Fe2+
and H2O2 and solar radiation).
The degradation of reactive yellow 145 dye by Fenton and photo-Fenton processes was
investigated. The degradation rate was strongly dependent on pH, initial concentrations of
Fe2+
, H2O2, temperature and light intensity. The optimum conditions were found at pH 3 for
Fonton and Photo-Fenton processes. The decolourization experiments indicate that dye can
be effectively decolourized using Fenton and photo-Fenton processes with a little difference
between the two processes, 91.4 and 97.8 % within 0.5 h, respectively for optimal
conditions. The difference in docolourization is not similar to COD removal: with Fenton
process there is significant increment (52.27 % COD removal) relatively to photo-Fenton
process (only 38.63 % COD removal).

participated in this study. All of them were asked to answer a standard questionnaire covering
standard demographic questions and those about medical history. Among the 50 individuals in each
of the arsenic contaminated and non-contaminated groups, 15 diabetic subjects in each group and
20 non-diabetic subjects in each group were selected for the collection of blood. Total of 12 water
samples were collected to check the concentration of arsenic in contaminated area. Comet assay
was used as biological marker and DNA damage was scored empirically using a numerical rating
system. There was a clear DNA damage in population of contaminated area. Although, there was
also slight damage in the DNA of non-contaminated population which may be due to some
environmental effects. The results clearly indicate that arsenic affects the genotoxic parameter.

metals (HM). Therefore, an experiment was conducted to evaluate HM fractions in contaminated
soil with or without clay amendments were determined. The material was applied at the rate of 0%,
2.5% and 5% to the polluted soil. The amended soil samples were incubated for four weeks. The
metals were stepwise fractionated into exchangeable, adsorbed, organically bound, carbonate
precipitated and residual forms. Extraction of elements from amended soil considerably varied
depending on the chemical reagent. Metals were varied in the order of Pb > Cr > Ni. The
concentrations of water soluble metals in soil were found less than other fractions. A great
proportion of metals were noticed in carbonate and residual forms. Overall metal fractions
extracted by reagents varied in the order of HNO3 > EDTA > NaOH > KNO3 > H2O. Increasing
application of clay apparently decreased the concentration of HM in polluted soil irrepective of the

Polyhydroxyalkanoates (PHA) are efficient, renewable and environment friendly polyesters.
Various bacterial species accumulate intracellular polyhydroxyalkanoate (PHA) granules as energy
and carbon reserves inside their cells. Polyhydroxyalkanoates is a family of biopolyesters with
diverse structures. PHAs are the only bioplastics which are completely synthesized by
microorganisms. This work was done to find out the ability of various bacterial strains to produce
PHA using different carbon sources (Glucose and Cannola oil), to check lipase activity among
different strains, and to check PHA production by lipase positive and lipase negative organisms. All
strains were identified by basic microbiological and biochemical tests. After checking their lipase
activity using Tributyrin agar followed by growing the strains on PHA detection media. Screening
for bioplastic production was done by Nile blue and Sudan black B staining. PHA positive strains
were further checked out for the quantity of PHA produced by them in PHA screening media with
glucose and cannola oil as carbon sources. Strains 1,2 and 5 showed lipase activity while strains 3
and 4 did not show. In nitrogen limiting conditions, Strain 1 showed maximum growth at 72 hrs in
both carbon and cannola sources. Strains 2, 4 and 5 also showed same trend like strain 1 while
strain 3 showed maximum growth in case of, glucose at 48 hrs and cannola at 72 hrs. All Strains
either lipase positive or lipase negative can produce PHA in harsh environment i.e nitrogen
limitation (in this case). But their produced quantity can vary according to used carbon source. It
can also be concluded from results that maximum production happens in double harsh environment
(Nitrogen limitation and Oil).

The studies were conducted to find out the effect of different shaded conditions of Eugenia
jambulana trees on two onion cultivars collected from surrounding market area locally called
Indian and 144. The growth parameters of onion cultivars were recorded under un-shaded, partially
and fully-shaded canopies of Eugenia trees already grown on a waste land of Nuclear Institute of
Agriculture and Biology, Faisalabad. The transplanted seedlings were fertilized with just one bag of
NH4 (SO4)2 (i.e. 50 kg) and half of urea and MOP (i.e. 25 kg) acre-1
of each were applied with first
irrigation. Maximum weights of bulbs (162.62±9.10 g) of onion were recorded in Indian cultivar
under shaded conditions of E. jambulana trees followed by cultiver 144 under un-shaded
conditions (135.12±7.40 g). Maximum horizontal diameters (7.83±0.77 cm) were recorded in
Indian cultivar grown under un-shaded conditions. The maximum circumferences (24.20±2.44 cm)
and number of leaves per plant (15.14±0.25) were observed in Indian cultivar. Similarly maximum
yield (18.0±0.11 ton ha-1
) was recorded in small sized bulbs under partially-shaded conditions,
medium sized (10.58±0.41 ton ha-1
) under partially-shaded and large sized (6.23±0.36 ton ha-1
)
under fully-shaded conditions in Indian cultivar whereas lowest (14.58±0.59 ton ha-1
) was recorded
under fully-shaded conditions of E. jambulana trees in cultivar 144. Highest firmness (8.25±0.54
lbs) and moisture levels (81.0±4.66%) were recorded under partially-shaded conditions in Indian
cultivar whereas more weight losses (50.0±0.25%) in cultivar 144 under un-shaded conditions.
More sprouting was observed in Indian cultivar (40.0±2.11%) under un-shaded whereas least
(18.0±3.55%) under partially-shaded conditions in the same cultivar. It was inferred from current
studies that Indian cultivar proved better than cultivar 144 however, both varieties could be grown
under shady conditions and be beneficial on wasteland.

Field studies were conducted on sandy clay loam soil to evaluate growth and yield response of
Cyamous tetragocalobe (cluster bean) under shady trees of Eugenia. No fertilizer was applied
to any treatment and the crop was irrigated with three intervals of times. Crop were sown under
three environmental (i.e. without shade (control), shaded and partially shaded) conditions.
Results showed that response of yield was higher (19% and 9% in fertile pods; 23% and 12% in
seed weight, respectively) in crop which were grown without shade than shady and partially
shady conditions. It was concluded on the results data basis that Cyamous tetragocalobe could
also be cultivated in wasteland under shaded environments; however, its overall growth
response was more in un-shaded conditions.

Textile effluent is the waste water that comes from textile units at various stages of production. It has diverse and
complex chemical composition but dyes are the frequently dominant constituent of the textile wastewater. Among
the variety of dyes, azodyes are used most widely in the textile industrially. When this effluent is discharged into
water bodies, it potentially contaminates water bodies on large scale. Control of water pollution from textile
wastewater has become increasingly important in recent years. These effluents are being used for irrigation in
agro-systems for the production of crops. But these can have detrimental effect on the growth and development of
crops. Consequently, different dilution factors are used to reduce its negative impacts on crops. The present study,
therefore, was conducted to investigate textile effluent effect on the growth and germination of maize (Zea mays
L.) and mungbean (Vigna radiata L.) under axenic conditions. For this purpose, textile effluent was collected from
Dawood Textile Mills Faisalabad and was applied to maize and mungbean crops at different concentration levels
in a two-week pot experiment under laboratory conditions at Institute of Soil and Environmental Sciences,
University of Agriculture Faisalabad. In addition, effect of textile wastewater on seed-germination of these crops
was also assessed under laboratory conditions. Textile effluent significantly hampered the growth and
development of both crops, especially at 100% concentration level; however, mungbean crop showed more
pronounced sensitivity compared to maize crop. It is suggested that such a negative impact on growth and
germination could be attributed to high salt contents of textile effluents. However, it was noticeable that textile
effluent at moderate concentrations (25%) had shown positive effect on growth parameters. It is hypothesized that
biodegradation of textile wastewater dyes results in plant consumable N-compounds which stimulate their growth
and development; however, the idea needs to be addressed and verified though sound research in future.

The global warming that is directly or indirectly related to human activity that alters the
composition of the global atmosphere and which is in addition to natural climate variability
over comparable time periods. The past temperature trends over Pakistan are seen very much
tallying with the global trends, Furthermore, Pakistan located in sub-tropics and in temperate
region, has a warm climate and its economy being largely agrarian, is highly climate sensitive.
Pakistan is the least responsible for global climate change, but remains severely impacted by
the negative effects of climate change like crop yield growth rates are declining in Pakistan,
accelerating recession of glacier melt in the Himalayas, rainfall variability and changes in
marine ecosystems, freshwater availability is also projected to decrease which will lead to
biodiversity loss, Coastal areas bordering the Arabian Sea in the south of Pakistan will be at
greatest risk due to increased flooding, Endemic morbidity and mortality due to diseases
primarily associated with floods and droughts are expected to rise as a consequence of rising
temperatures. Increasing access to high quality information about the impacts of climate
change, developing new and innovative farm production practices and irrigation techniques,
improving forest management and biodiversity, mainstreaming climate change into
development planning at all scales, levels and empowering communities and local stakeholders
promoting good governance and responsible policy by integrating risk management and
adaptation, practicing energy efficiency through changes in individual lifestyles and businesses,
reducing the vulnerability to livelihoods to climate change through infra-structural changes can
be taken to cope with climate change and avoid global warming.

480 km in length and between 32 and 192km in breadth. Human and livestock population in the desert is
0.1 and 2.0 million respectively. The paper emphasis on the qualitative analysis of the two dominant
production systems in the Cholistan desert: (1) an agro-pastoral system representing about 75 % of the
population, composed of irrigated agriculture undertaken in association with the raising of livestock that
are either stall-fed or grazed in the desert; and (2) a pastoral system which comprises chiefly of a trans
humant element, involving the seasonal movement of people and livestock in the desert made up of
herders representing about 25 % of the population. The qualitative analysis, also examines that relative
inefficiency of agriculture activity in Cholistan reflects the influence of physical, economic, social, and

Global warming, caused by the emission of greenhouse gases, is a topic of wider global concern causing
environmental, ecological and social concerns in human society. Carbon dioxide emissions from anthropogenic
sources are estimated to be 22 billion tons per annum and are thought to be 72% of the overall green house gas
emission (GHGs) of the world. The concentration of carbon dioxide in the atmosphere has increased from 290
ppm in 1900 to nearly 400 ppm in 2010, and it is currently increasing by 2 to 3 ppm each year. Major source of
carbon dioxide is burning of fossil fuels like oil, natural gas, diesel etc. The emissions of CO2 have been
dramatically increased within the last 50 years and are still increasing. There are a number of options available to
cut down the carbon dioxide emission such as use of alternative energy sources, carbon capture and storage
strategies etc. At this time, we need to store and capture the CO2 from the atmosphere by carbon sequestration
methods including biological, chemical and/or physical processes. Carbon sequestration at more advanced levels
is targeting development of fast-growing tree and grass species, and deciphering the genomes of carbon-storing
soil microbes. These activities complement research into afforestation and agricultural practices. We can control
the rising temperature by planting trees which has been considered have been touted as way to become carbon-
neutral. It has been estimated that a single mature tree can absorb carbon dioxide at a rate of 48 lbs/year and
release 260 pounds oxygen back into the atmosphere to support 2 human beings. According to the World Bank’s
Pakistan Strategic Country Environment Assessment Report, the cost of environmental degradation is at least 6
percent of the Gross Domestic Product (GDP) or about Rs.365 billion per year. Pakistan is a country of diverse
landscape and contains within its boundaries six major forest types, ranging from forest cover on some of the
highest mountain ranges in the world to mangrove forests along the low lying coastal belt. Pakistan’s annual rate
of deforestation, between 2000 and 2005, was 2.1 percent, which was the second highest in Asia after
Afghanistan. According to the National Forest and Range Resource Assessment Study (NFRRAS) by Pakistan
Forest Institute (PFI) in 2004, the total forest cover of Pakistan has decreased to 3.317 million hectares. There is
strong potential of sequester carbon dioxide in Pakistan through planting trees but only through education, policy
making and active government involvement.

Air Pollution and climate change is serious challenge of developing countries like Pakistan. To
study the impact of PM2.5 (Particles with an aerodynamic diameter of 2.5 µm or less) and Black
Carbon (BC) concentrations on Pakistan’s climate, PM2.5 and BC are simulated using the Weather
Research and Forecasting, Chemistry (WRF/Chem) model over Pakistan during the period from 24
to 28 August 2006. The David Street emissions data for Asian countries have been used. The model
results are compared with published data and other available information has been analyzed. Model
result showed higher concentration of PM2.5 over Punjab region which adjacent to northern India.
PM2.5 concentration observed higher in the morning and evening hours and lower in afternoon.
Daily mean PM2.5 varied about 11 to 18µg/m³ and compared it with winter season. PM2.5
concentration is much lower than the winter season, which is reported upto 500 µg/m³, (Lodhi et al.
2009). The model results have been compared with measurements results of Aug 2007 which is
exactly after one year of model simulation to emission pattern. Emission trend is almost same that
model showed in Aug 2006. Daily mean of Black Carbon varied from 2 to 2.5 µg/m³. Model result
is compared with measurements result of the same month Aug 2006. Model result almost same as
reported by Dutkiewicz et al., 2009. From July to Aug is monsoon season in Pakistan,
concentration of particulate may be lower due to rain, air born species washed out in this season
and concentration reported lower than winter season which much higher during fog episode. Due to
rapid urbanization and industrialization have increased PM and BC emission that has serious
impact on human and climate.

Industries are very important components of a country’s progress; because they play a significant
role for the economy of a country. The industries waste water produces from the nature of many
industries that needs large quantity of water for their Processing and wastes disposal. Many of the
industries are therefore, situated near water sources. The wastewater of industries has the higher
concentrations of different polluting substances and is produced large quantities, so the pollution
present in industrial wastewater is by many times greater than that of domestic wastewater. The
number of industries is very high which discharge waste water directly into the waste water of
rivers and lakes which produce threats for the aquatic life. The current study is the physico-
chemical analysis of parameters of waste water. In this work, the samples were collected from
industries including sugar, Pharmaceutical, paper, food processing, municipal wastewater and
textile industries. Untreated wastewater samples was collected from their discharge point and was
tested for physical and chemical parameters like pH, total suspended solids (TSS), total dissolved
solids (TDS), chemical oxygen demand (COD), biological oxygen demand (BOD), dominant
cations (Na+, K+, Ca2+, Mg2+), dominant anions (Cl-, SO42-, PO43-) and heavy metals including
Pb, Cr, Ni and Cu. The measured values were assessed in comparison with those of National
Environmental Quality Standards (NEQS) permissible limits, which allowed us to figure out
various environmental contamination threats emerging from these industries.

Crop residue production, decomposition and management are central processes of nutrient cycling and recycling
in agro ecosystems. The present microcosm study was designed to investigate impact of rice residue management
practices (no-till and conventional tillage) on nutrients fluxes in drainage water over a period of four months. The
treatments included control, surface residue application (no- till/zero tillage) and subsurface residue incorporation
(conventional tillage). The microcosms were irrigated with simulated rain of known composition bi-weekly and
drainage water was collected at a two week interval. Treatment effects were statistically explored through one way
analysis of variance (ANOVA) using standard statistical methods. Pearson’s correlations coefficients were used to
study the nature of relationships between leachate physicochemical parameters. The leachate samples were
analyzed for pH and the pH of sub-surface residue samples were 8 which showed that soil was alkaline in nature.
From the results, it was concluded that the concentrations and fluxes of nitrate, ammonium, mineral-N, sodium,
potassium and chlorine were higher in surface residue (no tillage practice) soils compared with those from the
control and sub-surface residue, but the other remaining parameters had low concentrations. Nutrient
concentrations were converted into fluxes using the volume of leachate samples. The cumulative fluxes showed
that fluxes of nitrate, ammonium, dissolved inorganic nitrogen (DIN) and potassium were high in surface residue
treatment and chlorine and sodium had low fluxes for the same treatment. Future research should address how
above- and belowground decomposition processes differ for a wider range of crop residues and nutrients,
emphasizing both short and long-term nutrient recycling.

Solar energy is generated by the process of nuclear fusion in tremendous amounts that by traveling at the
speed of light, arrives from the sun at the earth at 170 thousand million joules every second. Of which,
About 30-33% radiation energy is reflected straight back into space and 67% of sunlight actually heats the
Earth. As one of the cheapest, clean, reliable and affordable type of energy and alternative fuel, it produces
a large amount of energy in a small place. It is partly responsible for wind energy and geothermal energy.
Solar energy is vital to support life on earth. Use of solar technology has developed from the simplest use
to make fire to the object to be burned to run modern machinery all over the world. Solar energy
generation is the real time solution to Pakistan’s growing energy scarcity problem, especially, in
agricultural and industrial sectors. A solar system that is economic at remote locations, energy storing,
cost-effective technology is helpful in water pumping, powering electric fans for air circulation, lighting in
agricultural buildings and enclosures, appropriate uses for ranches and orchards like Power for feed or
product grinding, electric-powered egg collection and handling equipment, Product refrigeration,
Livestock feeder and sprayer motors and controls, Compressors and pumps for fish farming, electric
fencing to contain livestock and battery charging etc. As an indirect use, it is helpful as crop and grain
driers, space and water heater – particularly in livestock operations. A solar greenhouse reduces the need
for fossil fuels for heating. A study showed that the food processing, pharmaceutical, automotive, dairy,
textile, and pulp and paper sectors are the ones that have the highest potentials of successfully operating on
solar power. Indeed, solar energy has a bright future ahead and will find many applications in various
sectors of Pakistan.

Brevicoryne brassicae L. and Lipaphis erysimi (Kalt.) are major insect pests of canola, Brassica napus L.
in Pakistan. Our ten years’ studies have revealed that these species cannot be controlled without
application of insecticides. Present study was therefore undertaken to determine the effect of imidacloprid
and thiamethoxam seed treatment on population of both aphid species on canola variety ―Oscar‖.
Experiment was conducted at Multan in a Randomized Complete Block Design. Crop was sown with the
seed treated at three different doses of each of the imidacloprid 70 WP (@ 3.5, 5.0 and 6.5 gm/ kg of seed)
and thiamethoxam 70 WP @ 2.0, 3.0 and 4.0 gm/ kg of seed). Number of aphids (cabbage aphid + turnip
aphid) was recorded from late January to mid March from 12 plants in each treatment from 10 cm terminal
part of inflorescence. No significant difference in number of aphids among treatments was observed on any
sampling date. Mean seasonal aphid population also did not differ among treatments. It is concluded that
seed treatment of canola is not effective for management of aphids in southern Punjab, Pakistan.

The total arid area of the world is increasing rapidly due to considerable changes in climate and
rainfall patterns caused by global warming. This recent change of high temperature and depleting
water resources is badly deteriorating ecosystems. Green lands are turning into barren. Without
plantation, ecosystems are eroded. Ecosystem may be restored by growing more plants. But how
can plants survive in extreme temperature and drought? Pakistan has an arid to semi-arid climate.
Of the total 79.6 million hectare of the country, only 9% receives more than 508 mm rain per
annum. Further reduction of rainfall is predicted in future. Although supplemental irrigation by
canal water is available for some areas however, it is not enough to fulfill the needs of crops.
Drought or water deficit is defined as the absence of adequate moisture necessary for normal
growth and completion of life cycle of a plant. Plants suffer drought when water supply to the roots
is very low due to less soil moisture or when transpiration rate is very high. These two conditions
usually occur together under arid or semi-arid climates. Problem of drought is acute in the
developing part of the world where there are a few opportunities for adopting drought management
strategies such as irrigation. Scientists have been striving to find and implement strategies to
manage dry ecosystems and to help plants survive in those arid areas. Naturally plant species on
land have developed some adaptive strategies to tolerate water deficit thereby maintaining growth
and development. Plant biologists have been studying these plant adaptive mechanisms to
manipulate them for generating drought tolerant crop cultivars. Plants can also be genetically
engineered to naturally resist drought conditions of the environment. Plant scientists are trying a
variety of plant hormones involved in cellular metabolism for their ameliorative role against
drought stress. A novel idea is to use ascorbic acid (vitamin C) to save plants under drought stress. I
have conducted experiments which reveal that ascorbic acid being an antioxidant has the ability to
effectively mitigate the adverse effects of drought stress if sprayed or given in the rooting medium
to wheat under stress.

Pakistan is an agricultural base economy and 65 percent population of the country is involved directly or
indirectly in this sector. The green revolution has several impacts on its agricultural practices. The high use
of fertilizers is being incorporated with the soil and leaching down to the groundwater, causing pollution
and eutrophication of these natural reserves. Phosphorus (P), a nonrenewable resource is being used
intensively and this trend will lead to the complete depletion in coming 100 years. The authors collected
data regarding P fertilizer usage in Pakistan for the last twenty years from published papers, national
reports, and government departments. The aim of the present study was to evaluate the effect of inorganic
agricultural inputs (fertilizers) usages on the sustainable and environmental friendly agricultural production
in Pakistan. Cotton and wheat are the two major crops of Pakistan. The fertilizer use was increased to
108% during the last two decades (1990-91 to 2010-11). Whereas the average yields increase during this
period was 18% and 54% in cotton and wheat, respectively. Therefore the need of the time is to use P
fertilizer accordingly to minimize the environmental hazards and to improve the soil health.

Sunflower (Helianthus annuus L.) is a major oilseed crop not only in Pakistan, but also all over the
world. It is much susceptible to climatic variables and hence climate could have significant effect
on its production. The experiment was conducted during spring 2011 in greenhouse of Department
of Plant Sciences, Quaid-i-Azam University, Islamabad. The effects of Nitrogen (N) and Plant
Growth Promoting Rhizobacteria (PGPR) on growth and development of sunflower (Helianthus
annuus L., var. Hysun-33) under natural environment were studied. The N use efficiency of
sunflower crop grown under three N rates (N1 = 0 kg ha-1
, N2 = 120 kg ha-1
, N3 = 240 kg ha-1
) and
three PGPR levels (R1 = 0 kg ha-1
, R2 = 30 kg ha-1
, R3 = 60 kg ha-1
) were investigated. This study
presents results of a simulation study to evaluate the impact of projected climate change on
sunflower in contrasting agro-environments in glass house environment by making different
treatments within the model for various temperature and CO2 levels. The OILCROP-SUN model
that is part of DSSAT (Decision Support System for Agro-technology Transfer) has reasonably
predicted phenology, crop growth, development, yield and yield components of sunflower crop.
The simulation results showed that their is increase in CO2 concentration from 360 ppm to 550 ppm
has no affect on crop duration. On the other hand, leaf area index (LAI) that results in total dry
matter (TDM), will increase with increased CO2 concentration. Results of present study showed
that, increasing temperature will shorten crop duration from planting to physiological maturity
(with difference of almost 14 days in 2020's and 21 days in 2050's, respectively), thus retards the
growth and development and ultimately decreased the yield than current situation at all the
experimental locations of Punjab-Pakistan. Furthermore, for maximum economic benefits
(maximum growth and development that’s lead to higher achene yield), application of 120 kg N ha-
1 was better under well irrigated conditions compared to other different N levels. Further research
especially in the field of crop simulation modeling may be required in this area for sunflower crop
to identify best agronomic management strategies in order to achieve high yield and profitable
edible oil production of Pakistan.

Textile sector is often considered as the backbone of Pakistan’s economy. It is the most important
industrial sector in terms of export and involves human resource to a much greater extent. Apart
from being one of the highest revenue generating sectors, it has several tribulations, one of them
being the environmental pollution. Water, air and noise pollution and the solid waste generation are
the main problems which turn out to be a serious health hazard for flora and fauna. Increasing
global awareness about these environmental hazards has triggered international environment
protection agencies and governments to impose stringent pollution regulations. International
certification requirements for ISO 14001-EMS is also becoming essential dynamics of the global
market. These standards are also implemented in Pakistan. If these standards are not followed
precisely, the Pakistan textile products will start losing their competitive edge in the international
markets.The purpose of this study is to develop better understanding of the textile processes, related
environmental issues and the available techniques for controlling the environmental pollution and
also to understand the components of ISO 14001 Environmental Management System (EMS). To
achieve this goal, I worked with NEC Consultants (Pvt.) Ltd team in one of their projects: Cleaner
Technology Program for Textile industry (CTPT). The processes of ISO 14001-EMS
implementation in Nimra Textile (Pvt.) Ltd (NTL) was studied in detail with help of literature review,
industrial survey and checklists. By these tools, it was found that most of the environmental aspects
of NTL were exceeding the NEQs and company was willing to improve its environmental
performance. That’s why the NTL takes services from NEC team as consultants. So, NEC team
suggested them to implement ISO 14001-EMS standards in their company and provide guidance
for its implementation.

seedlings. Young V. faba seedlings were exposed to 5 µM of lead nitrate in the presence and
absence of ethylenediaminetetraacetic acid (EDTA) and citric acid (CA). All the treatments were
exposed for 1, 4, 8, 12 and 24 h in controlled hydroponic conditions. The results showed that Pb
toxicity to V. faba depends on its speciation and duration of exposure. Lead alone caused two burst
of lipid peroxidation and H2O2 induction at 1 and 12 h in V. faba roots. In leaves, Pb-induced H2O2
induction and lipid peroxidation started after 8 h. Addition of EDTA dose dependently inhibited
Pb-induced lipid peroxidation and ROS production indicating a protective role of this metal
chelator. In contrast, CA did not show significant effects on Pb-induced lipid peroxidation and ROS
production, but delayed the induction of effects. The present study suggested that metal speciation
plays important role in early steps of Pb toxicity to V. faba seedlings.

The study was conducted to screen nine varieties of brinjal, Solanum melongena L. for resistance
against jassid, Amrasca bigutulla bigutulla (Ishida). Brinjal nursery was grown in pots and
transplanting was done on September 4, 2011. Experiment was planted in a randomized complete
block design having four replications. Each plot had four rows. Plant to plant and row to row
spacing was 10.0 cm and 50.0 cm, respectively. Data were recorded from the middle two rows of
each plot. Number of jassid (adults + nymphs) was counted in early morning hours on the
underside of three leaves from each plant by randomly selecting two plants from each row of each
plot. The three leaves chosen were; one from the top one third, one from the middle one third and
one from the bottom one third of each plant. Highest number of jassid per leaf was observed on the
variety Black Beauty on all sampling dates. The varieties Nirala and Hybrid 3715 had the lowest
number of jassid per leaf on most of the sampling dates. Seasonal mean number of jassid per leaf
on different varieties was in the order; Black Beauty > Dilnasheen > Hybrid Shilpa = Round Black
>Bemisal > Hybrid 888 > Black Pearl > Hybrid 3715 > Nirala. Based on the seasonal mean
number of jassid per leaf, brinjal variety Black Beauty, having 14.6 jassid per leaf, was highly
susceptible, Dilnasheen, Hybrid Shilpa, Round Black, Bemisal, with jassid number from 3.0 to 3.8
per leaf., were moderately resistant and Hybrid 888, Black Pearl, Hybrid 3715 and Nirala, with
jassid population ranging from 2.3 to 2.7 per leaf, were resistant against jassid. Jassid per leaf,
averaged over all the varieties screened, started to build from 49 days after transplanting (DAT)
and reached a peak on 63 DAT. Thereafter number per leaf decreased up to 84 DAT.

Bacteriocins have attracted much attention due to their potential use as antibacterial agents for the
treatment of infections, preservation of food and animal feed. Bacteriocin have been found in all
major bacterial groups and recently been described as universally produced by some members of
the Archaea. The present study was carried out for screening and molecular characterization of
bacteriocin produced by bacteria isolated from rhizospheric soil. Rhizospheric soil samples were
collected from the indigenous areas of Punjab University to isolate bacterial strains that exhibit the
antibacterial activity. Extraction and purification of the bacteriocin was done by TLC and SDS-
PAGE. Purified extracts were treated with high temperature 121°C, Proteinase K and UV radiation
to check the stability of the bacteriocin. Five out of ten bacterial strains (AZS, A2, P, U and LB)
showed high bacteriocin activity against the target organism. The stability of the crude extract of
bacteriocin to high temperature 121°C, Proteinase K and UV radiation indicated that these
compounds could be a better option for utilization as a probiotics. The SDS-PAGE analysis
indicated that bacteriocin were low molecular weight peptide i.e. molecular weight of
Brevundimonas and Bacillus (A2, AZS & LB) was approximately in the range of 10 to 25 kDa
whereas the molecular weight of Pseudomonas and Alcaligenes (P & U) was approximately 40
kDa. It was concluded that bacteriocins are low molecular weight compounds with diverse stability
which indicated that these compounds could be a better alternative to antibiotics.

Nickel (Ni), 22th
abundant element in the earth crust, being an essential mineral nutrient found in
natural soils in trace concentrations. The elevated levels of Ni pollution in the environment are due
to industrial and agricultural activities. It is vitally important to understand both, the functional
characteristics and toxic effects of Ni in plants. The quantity of Ni required for normal growth and
development of plants is very low. However Ni has been identified as a component of various
enzymes in plants and has decisive metabolism for certain enzyme activities, like maintaining
proper cellular redox state and various other biochemical, physiological and growth responses. The
higher concentration of Ni is associated with serpentine soils, manifestation in plant chlorosis and
inhibits root and shoot growth. Excess of Ni inhibits a large number of enzymes and interferes with
several aspects of plant biochemistry, including photosynthesis, pigment synthesis, and membrane
integrity. This article is based on the overview of available data of past two decades that in core
encompasses the ill morphological, physiological and biochemical effects of Ni stress on plants.

Manganese is an essential nutrient to all plant species. After year to year study it has been
documented that different plant nutrients show a complex interaction, which effect their absorption
and utilization in plants. In plants manganese takes place in the synthesis of chlorophyll and in the
oxidase enzymes activity such as dehydrogenase, transferase, hydroxylase, and decarboxylase
involved in respiration, amino acid, lignin synthesis as well as in hormone production. But the
elevated amount becomes toxic for plant. The phytotoxicity of manganese resulted in the reduction
of crop yield, photosynthesis, and biochemical disorders. A compatible role of antioxidative system
has been reported as a defense mechanism in relation to high Mn concentration. The purpose of this
review is to show the effects of Mn stress on plants in contact to morphological, physiological and

In Pakistan, like many other developing countries of the world, hospital and medical waste
management practices are very unsatisfactory. Existing techniques and practices are not in
accordance with the guidelines and levels prescribed by the WHO and other international bodies
concerned with environment and human health. Reasons for poor management of infectious and
hazardous waste from hospitals are lack of legislations, inability to adapt international protocols
and guidelines for hospital waste management such as waste minimization, segregation, collection,
storage, final treatment, recycling and disposal. Lack of trained and literate manpower, equipment,
and socio-economic status of the country are major obstacles which hinder the proper and effective
management of hospital waste. At present in most of hospitals present in country, waste is not
managed properly. Mostly hospital waste is disposed off together with domestic and municipal
waste or is openly dumped without any prior treatment. Moreover due to financial crises in country
scavengers collect recyclable waste such as syringes, glass vials, and plastic bags which are highly
infectious in nature. These items are repacked and reused. This exercise is affecting the community
health to a large extent. Use of contaminated syringes has contributed a lot in spread of infectious
diseases like hepatitis B, C and HIV in the country. Many drug users pick syringes from debris and
use them which can transmit infectious diseases to community. Many small-level medical facilities
even dump their waste in nearby water courses. Syringes, needles, sharps, blood bags and other
type of medical waste are found in most water courses running through urban areas. Objective of
this study was to design and implement a proper waste management plan for the PINUM hospital
Faisalabad, Pakistan. At PINUM hospital, infectious waste was produced as a result of diagnostic
and radioactive waste was produced as a result of diagnostic and therapeutic activities in nuclear
medicine. This study was carried out in a period of 10 months in two phases.In first phase a proper
infectious waste management plan was design and incorporated at hospital and in 2nd
phase proper
management plan for radioactive waste was designed and implemented. Nested PCR was also
performed to check any virulence for hepatitis B and C in incinerated ash of infectious waste
arising from diagnostic labs. Results showed a 45% reduction on treatment cost and significant
volume reduction of infectious waste due to proper management. There was significant decrease in
prescribed` storage time of radioactive waste which is done to bring its activity to normal level. It
was seen that if radioactive waste properly segregated, lose radioactive waste
(gloves,swabs,absorbing sheets, tissue papers etc.) can be disposed off much earlier than the
compact radioactive waste (radioactive vials, needles, sharps etc.)

Urease (urea amidohydrolase; E.C. 3.5.1.5) is a metallo enzyme which usually found in plants and
microbes (algae, fungi and bacteria). It is ubiquitous that catalysis the hydrolysis of urea in the soil
by using a bimetallic nickel center. It is involved in the final step of organic nitrogen
mineralization. In plants, the major role of urease is to facilitate it’s growth by providing nitrogen
in the form of ammonia. High catalytic rate of urease in soil may results in excessive release of
abnormally large amounts of ammonia into atmosphere. If the hydrolysis of ammonia does not
occur in the soil surface, soil pH will increase due to liberated OH- ions, ammonia will escape to
atmosphere hence ammonia volatilization will occur which may lead to environmental and
economic problems. In order to protect the crops from volatilization loss of ammonia, various
inhibitors are used that can retard urea hydrolysis by blocking the activity of urease enzyme. Soil
urease inhibitors are Phenylphosphorodiamidat, Hydroquinone, N-(Diaminophosphinyl)-N-Benzyl-
N-methyl phosphoric triamide (NBPT) ,Trichloroethyl phosphorodiamidate Diethyl phosphoric
triamide, Dimethyl phosphoric triamide and N-Butyl phosphorothioic triamide . In silico studies
have been carried out to understand the interaction of inhibitors with urease by using different
bioinformatics tools. Conformational changes occurred when ligand binds to the urease which
causes the inhibition of urease activity.

Heavy metals create serious problems in the environment due to their toxic nature heavy metals
such as Cadmium (Cd) and Lead (Pb) are widely distributed throughout the environment due to soil
erosion, industrial and agricultural processes. These metals accumulate in the environment causing
different diseases in living organisms. Toxicity of these metals has harmful affects on plants,
animals and soil microorganisms. Heavy metals have detrimental effects on the growth of some
crops. In this context, two varieties of mung-bean NM-92 and NM-98 were used for the present
study. The work was carried out in Plant Stress Physiology Lab, Plant Protection Division at
Nuclear Institute for Agriculture and Biology (NIAB) Faisalabad, Pakistan to examine the effect of
Cadmium and Lead in mung-bean (Phaseolus vulgaris, L.) in sand. The experiment was conducted
in net house after the germination in glass house. Four treatments control, Cd (1mM), Pb (1mM)
and Cd (0.5mM) +Pb (0.5mM) were applied to both varieties with three replicates before
germination in small plastic pots. Physiological and biochemical parameters were used to examine
the effect of these heavy metals on both varieties of mung-bean after the harvesting of 21 days. The
concentration of Cd and Pb in plants given Cd+Pb alone and in combination indicated the plant
tissue affinity for the uptake of the heavy metal ions in mung-bean and demonstrated the plant
ability for its use as a bio-accumulator. The lack of interaction between the ions indicated that
neither of the two ions had any antagonistic effect on the behavior of the other. This thus pointed to
the plant ability to accumulate both the ions equally well and perhaps at equal rate. The plants grew
well in both Cd and Pb and the two ions were distributed between tops and roots equally. Further
studies in mung-bean are aimed at characterizing absorption and distribution of Cd+Pb in the plant
further.

cauliflower, green pepper, spring onion and brinjal, irrigated with fresh and wastewater on ICP-
AES and also their proximate composition was accessed. The amount of Pb (1.87mg kg–1), Fe
(1.09 mg kg–1), Cu (1.01 mg kg–1), Zn (0.99 mg kg–1), Cr (0.97 mg kg–1) showed more
accumulation than Mn (017 mg kg–1) and Ni (0.31 mg kg–1) both the edible and leaves of
investigated vegetables but nearly all metals were found within safe limits. All the
samplesshowedlarge variation of elemental concentration however, wastewater grown vegetables
showed more accumulation of heavy metals than their respective fresh water irrigated vegetables.
Only Pb (1.87 mg kg–1) concentration in wastewater-irrigated vegetables exceeded the permissible
limits defined by World Health Organization (WHO).In leaves of vegetables more uptake of metals
were found than their edible portions. Of the two digestion methods nitric acid showed more
recovery of metals as compared to dry ash procedure.Continuous accumulation of these metals can

Phosphorus (P) being the 2nd
most significant plant growth limiting nutrient is crucial for growth and
nodulation of legumes. The use of chemical phosphatic fertilizers is unavoidable but these are costly and
mostly unavailable to crop plants when applied in soil. The need of hour is to find out alternate cheaper
sources of P or to reduce their use under current scenario. The use of rock phosphate enriched compost
might prove to be an economical and environment friendly technology. For this purpose a field study was
designed in which different levels of rock phosphate enriched compost (RP-EC) were tested for their
potential to improve growth, yield and nodulation parameters of chickpea and lentil. Already prepared RP-
EC was broadcasted @ 100, 200, 300, 400, 500, 800 and 1000 kg/ha in the field with four replications.
Recommended doses of N and K were applied in all treatments. Recommended doses of N, P and K were
(25-60-25 kg/ha for chickpea and 30-60-0 kg/ha for lentil) were applied in control. The application of RP-
EC applied @ 100, 200, 300, 400 kg/ha showed the insignificant but when it was applied 500 kg/ha, it gave
significant results incase of growth, yield and nodulation parameters as compared to control. Further
increase in the RP-EC levels i.e. @ 800 and 1000 kg/ha did not result in significant improvement in the
above stated parameters. So from the results, it was concluded that application of RP-EC @ 500 kg/ha or
more significantly improves nodulation, growth and yield of chickpea and lentil.

important aspects of plant growth through regulation of several growth processes such as seed
germination, stem elongation, uniform flowering, increased flower number and size. Exogenous
application of GA3 hastens the vegetative and reproductive growth of plants. A study was planned
to evaluate the effectiveness of GA3 applied as foliar application for enhanced vegetative and
reproductive growth of okra. Results revealed that increase in number of foliar application of GA3
substantially improved the vegetative as well as reproductive growth of okra as compared to plants
receiving no foliar GA3 application. It was found that GA3 application at different growth stages of
okra predominantly boost the stem elongation, no. of leaves, no. of pods, no. of seeds per pod, seed
weight and seed yield. So, it can be concluded that foliar application of GA3 could be an effective
strategy for maximizing the growth and yield of okra.

Biosorption Pb(II) on chemically pretreated G. hirsutum (cotton) leaves waste biomass was
investigated in the present study. The Pb (II) sorption was found dependent on solution pH, initial
Pb (II) concentration, temperature and contact time. The chemical pretreatment of biomass resulted
in significant enhancement and reduction in sorption capacity depending on the nature of
pretreatment. Results revealed that chemical modifications of G. hirsutum (cotton) leaves waste
biomass with alkali, inorganic salts, organic salts and organic solvents enhanced the adsorption
capacity, while acidic pretreatments caused reduction in adsorption capacity. The sorption data was
fitted well to Langmuir isotherm and kinetic data to pseudo second order model, due to higher
value of correlation coefficient (R2). The effect of contact time showed that sorption of Pb (II)

The feasibility of using Ocimum bacilicum seeds for the removal of copper ions from aqueous
solution has been investigated. Batch biosorption studies were conducted to study the effect of
different experimental parameters such as initial metal ion concentration, contact time, agitation
speed, biosorption dose and pH. The result indicated that sorption equilibrium was established in 30
minutes. Biosorption efficiency was maximum at biosorbent dose 0.5 g. The copper sorption was
strictly pH dependent and maximum removal was observed at pH 5. Effective biosorption of
copper was taken place at 150-rpm. Maximum biosorption capacity was found to be 73.1 mg/g. The
influence of Pb, Zn and Ni on biosorption of copper was found in the order of, Pb > Ni > Zn. The
equilibrium data fitted well to the Langmuir isotherm model with R2
= 0.9979. The study revealed
that O. bacilicum biosorbent could be used as an adsorbent for the removal of other heavy metals
on large scale.

Phytoextraction is a technology that uses plants and/or associated microbes for the removal of
potentially toxic trace elements (TE) from contaminated soils. The efficiency of this approach
depends on the concentration of TE in the harvestable biomass (i.e. shoot) and the amount of
biomass produced. However, establishing the phytoextraction crops on TE polluted soils and their
performance may be limited by TE toxicity during the initial phase. Moreover, if soil conditions
favour high solubility of labile TE species, the use of phytoextraction may be limited because of the
risk of TE leaching from the root zone and/or deeper soil layers, depending on the contaminant
location, to the groundwater. We recently proposed a combined approach to overcome these
limitations, where initially TE are immobilized by soil additives such as red mud, and, after
successful establishment of the phytoextraction crop, being re-mobilized by application of
elemental sulfur to enhance the phytoextraction process. Here we present data from a pot study
where Salix smithiana was grown on two soils mainly contaminated with Cd and Zn polluted soils
treated with a mixture of gravel sludge and red mud. To mimic the rhizosphere acidification,
elemental sulphur was added. Soil pore waters were collected from planted and unplanted pots
using soil solution samplers and were measured for pH and TE concentrations (ICP-MS). Plants
were analyzed for TE concentrations after a growth period of 160 days. Our results show that the
solubility and bioavailability of Cd and Zn in both soils were strongly affected by the addition of
both amendments. Interestingly, soil pH plots against the corresponding mobilized TE
concentrations were explained only to some extent by soil acidification during sulfur oxidation.
Enhanced Cd and Zn mobilization was particularly observed in planted pots amended with sulfur.
Higher concentrations of Mn in soil pore waters indicated substantial reduction of Mn
(oxy)hydroxides due to partially aerobic rhizosphere conditions, explaining that Mn served as
electron acceptors during sulfur oxidation in O2-depleted zones. Enhanced Cd and Zn solubility in
the sulfur treatments was generally associated with substantially increased uptake of Cd and Zn in
willow tissues. It can be calculated that the observed magnification of Cd and Zn mobilization in
the partially anaerobic willow rhizosphere, i.e. at the location of plant uptake, upon addition of
elemental sulfur can substantially enhance the efficiency of phytoextraction process and seems
practical to keep the risk of TE leaching from the bulk soil relatively low.

The stimulation of seed germination by smoke and aqueous smoke extracts from the combustion of
plant material has received much attention in recent years. Here we report, that smoke derived from
a weed Bauhinia variegata (Fabaceae) can stimulate seedling emergence of the economically
important rice weed specie Echinochloa crus-galli (Barnyard grass-Poaceae). The result shows that
Plant extracted smoke tested seeds had a significantly higher speed of germination, germination
percentage, fresh weight, relative seed germination percentage, peak value, germination value,
shoot and root length, germination index and vigor index as compared to control. This research
highlights that plant extracted smoke can be used as a tool for minimizing weed impacts in
agriculture, horticulture and land restoration by stimulation and seedling emergence of the dormant
weed seed bank, followed by chemical control through known weedicide/herbicide treatments
without harming economically required crops in an eco-friendly way and may provide a new and
exciting opportunity for weed control.

TiO2 (P25) has been one of the most widely investigated and used photocatalytic materials Over the
past decades, because TiO2 is inexpensive, non toxic and chemically stable. Due to their broad
applications in the fields of H2 production, water and air purification, photovoltaic and
photoelectrochemical cells, TiO2-based nanomaterials have attracted significant research attention,
However, one of the major factors that limits the efficiency of TiO2 photocatalysis is its fast
recombination of photo-generated electron/hole pairs, which releases energy in the form of
unproductive heat or photons and alternatively lowers its efficiency. To solve this problem a simple
and straight forward approach i.e. hydration and dehydration process to synthesize TiO2-coated
carbon allotropes is presented here. The composite showed great activity for water reduction from
aqueous methanol (1 M) solution (photocatalytic reduction: PCR) and degradation of aqueous
pollutants (Phenol, methylene blue, and rhodamine B) (photocatalytic oxidation: PCO) under AM
1.5-light irradiation. The TiO2 NPs-coated Carbon allotropes exhibited 30 times higher
photocatalytic activity for H2 production compared to pristine TiO2. For the dye degradation The
composites showed good adsorption capacity, which further facilitated the enhancement of
photocatalytic activity of TiO2 NPs-coated Carbon allotropes for the degradation of dye molecules
while the degradation of phenol was not enhanced too much. excellent light absorption and charge
separation on the interfaces between the modified Carbon allotropes and TiO2 may be attributed to
the synergetic effect of the intrinsic photocatalytic activity of the composite.

grown for 21 days at varying nitrate: ammonium ratios (80/20, 60/40, 50/50, 40/60, 20/80 NO3-
/NH4+ ratios with 8 mM total nitrogen in Hoagland’s nutrient solution) under normal or saline
conditions (120 mM NaCl). Shoot fresh and dry biomass decreased with the decrease in nitrate:
ammonium ratio under non-saline conditions. Optimum nitrate: ammonium ratio for non-stressed
sunflower plants was 60/40 (1.5). Better growth of non-stressed sunflower plants at optimum
nitrate: ammonium ratio was associated with high uptake and use efficiency of N, due to nitrate
ammonium synergism, as well as uptake and utilization efficiency of other cations. Although high
nitrate: ammonium ratio reduced sodium accumulation in shoots of stressed sunflower plants, it can
not avert toxic effects of salt stress on the growth of sunflower plants.

Plants generally produce many secondary metabolites which constitute an important source of
microbicides, pesticides and many pharmaceutical drugs. Present research work is a part of such
investigations on Glacier Buttercup (Ranunculus glacialis). It belongs to the family Renunculaceae.
There is a very little work on this plant so far and limited information published on the biological
activities of this plant. So there is a need to analyze antimicrobial activity of this plant. The various
parts of Ranunculus glacialis were extracted with absolute methanol and further fractionated by
solvent-solvent extraction method with increasing polarity based absolute solvents i.e. chloroform,
ethyl acetate and n-butanol, n-hexane. The methanolic extract of various parts of Ranunculus
glacialis and their fractions were analyzed for their antioxidant and antimicrobial activities. It
contained appreciable levels of total phenolic and flavonoid contents. HPLC analysis of n-hexane,
chloroform, ethyl acetate and n-butanol fraction of various parts for total phenolic and flavoniods
also carried out. The GC-MS analysis of Ranunculus glacialis essential oil and n-hexane extract
revealed the presence of several compounds. The plant extract and fraction were assessed against
human blood erythrocytes (RBCs) for cytotoxicity studies by haemolytic activity.

This study monitored the accumulation of selected metals (Mn, Pb, Cu, Zn, Hg and Cr) in gills and
their relevance to the histology of these organs in Oreochromis mossambicus from two selected
sites of the Indus River in Mianwali district of Pakistan. These two sites were receiving agricultural
runoffs and municipal and domestic wastes. Selected metals were analysed by inductively coupled
plasma optical emission spectroscopy (ICP-OES). Mn, Cu, Zn and Cr in fish tissues showed
significant differences between two sites (P<0.01). While the Mn, Zn, Hg and Cr levels were higher
in gills of fish than the WHO standards, the Pb and Cu levels were within the permissible limits for
fish as a food for human consumption. Most common gill abnormalities observed in O.
mossambicus were desquamation of secondary lamellar epithelium, hypertrophy of epithelial cells,
lifting up of epithelium, intraepithelial oedema, aneurysm, hyperplasia, and haemorrhage at
primary lamellae. In conclusion the evidence of pathological alterations in gills of O. mossambicus
appeared to be a useful bio-marker to assess the impact of metal pollution in water on the health of
fish.

Plants have to adjust their water balance in response to very challenging environmental conditions
such as drought, salinity, and cold but also changes in light, nutrient deficiency or soil acidity. The
molecular and functional characterization of aquaporins, a class of membrane proteins that
facilitate water diffusion across cell membranes, has revealed the significance of their regulation in
response to these environmental stimuli Aquaporins are proteins embedded in the cell membrane
that regulate the flow of water. They are "the plumbing system for cells" Aquaporins are integral
membrane proteins from a larger family of major intrinsic proteins (MIP) that form pores in the
membrane of biological cells. Arabidopsis thaliana contains 35 members of this family. 35
members of this family were collected from available databases to perform multiple sequence
alignment Identification of conserved motifs within the Aquaporin family for function recognition,
Analysis of domains Prediction of secondary structure, study basis of common functionality of
different Aquaporin subfamilies in Arabidopsis and Development of Motif search tool using visual
basic programming. TAIR (The Arabidopsis Information Resource) SBASE was used for the
Identification of protein domains and function. Aminocomp was used to find Composition of
Amino Acids and their pI. Domain prediction of Aquaporin protein family showed that Major
intrinsic protein - like domain is present throughout the family members. Motif search of
Aquaporin Protein family showed following motifs are almost common to all members: 1) N-
glycosylation site. 2) N-myristoylation site. 3) Casein kinase II phosphorylation site. 4) Protein
kinase C phosphorylation site. 5) cAMP- and cGMP-dependent protein kinase phosphorylation site.
Secondary Structure Analysis and Composition of Amino Acids showed little divergence in these
proteins. The over all analysis of all the 35 members showed that they show similarity at structural
level so belongs to same family. But are involved in transport of different molecules, due to low
similarity at sequence level. This study provide insight for Functional characterization of these

Lead poisoning is an old but persistent public health problem throughout the world. Lead is a
ubiquitous environmental toxin that may result in severe damage to many body systems including
central nervous system, gastrointestinal, cardiovascular, haematologic, renal, hepatic and
reproductive organs. Oxidative stress is the destruction caused by free radical molecules.
Antioxidants protect and repair cells and neutralize free radical damage to organs and cell
membranes. We studied fifty two (52) blood samples from normal and lead exposed workers.
Different biochemical parameters were apply such as glucose, cholesterol, triglycerides, HDL-
cholesterol, LDL-cholesterol, creatinine, total proteins and total antioxidative status. Statistical
technique was applied for finding its correlation with anti- oxidtive status. Level of triglycerides,
cholesterol and glucose was very high in lead exposer workers as compared to control. HDL-
cholesterol, globulin were related negatively while, total proteins, triglycerides, LDL-cholesterol,
creatinine, glucose and cholesterol showed a positive relationship with total antioxidative status.

P-172 PRODUCTION OF SULFUR FREE COAL BY USING EU32 STRAIN OF
RHODOCOCCUS IN PRESENCE OF DIFFERENT SUBSTRATES
Muhammad Mustafa, Muhammad Afzal Ghauri, Nasrin Akhtar, Muhammad Ilyas
National Institute for Biotechnology and Genetic Engineering
Coal reserves in Pakistan are estimated to be more than 186 billion tons and are important for the
cost-efficient alternative to ethanol in Pakistan. Coal contains appreciable quantities of both forms
of sulfur, organic and elemental, with total sulfur content typically between 1- 4% but in some
cases being greater than 11%. Unfortunately, Lakhra coal contains 1.2 – 14.8% of sulfur that is the
major issue that we are facing in air pollution and acid rain. Removal of this sulfur is of prime
importance so that we can use it as clean energy fuel. Crushing washing, scrubbers, and
biodesulpherization are ways to reduce sulfur from coal deposits. Former two methods are not very
useful these days but biodesulfurization has played a vital role in clean fuel technologies.Organic
sulfur is present in the coal in the form of dibenzothiophene. The initial oxidation and cleavage of
one of the aromatic rings by conventional methods initiate the complete degradation of the
molecule to CO 2, H2O and SO4. This pathway, also called Kodama pathway, involving the C-S
cleavage as well as C--C bond cleavage which is undesirable due to the lack of specificity for sulfur
resulting in the degradation of aromatic hydrocarbon compounds thereby greatly reducing the
efficiency and the calorific value of the fuel. On the other hand, biodesulferization has made a great
break through in cleaning of sulfur containing coal deposits which can degrade dibenzothiophene
(DBT) aerobically without cleaving C-C bond and, hence, do not decrease the calorific value of
coal by using Acidothiobacillus ferroxidans. EU32 strain of Rhodococcus was used for
desulfurization of pyrite bearing coal deposits of Larkana. Rate of desulfurization of
dibenzothiophene was tested in presence of different carbon sources. Gulucose+Sodium Citrate was
proved as best carbon source for production 2-HBP (2-hydroxybiphenyl) which is the pure form of
coal without any organic of elemental sulfur. This microbial desulfurization process which removes
organically bounded and elementally present sulfur without cleaving g carbon-carbon bond from
the coal, thereby operating at efficiency, and retaining the calorific value of the fuel.

Soil organic carbon (SOC) plays a key role in several physical, chemical and biological soil
processes that contribute productivity of agricultural soils. More researches are mainly focused on
the dynamics of total SOC and particle fractions of SOC in the upper surface (0–20 cm) layer of
soil. A few studies were conducted to examine the labile and recalcitrant fractions of SOC in
different soils, much less along further soil profile or under long-term application of manure and
fertilizers. Thus, in the present study, an attempt has been made to evaluate the effects of long-term
manure and fertilizers on labile and recalcitrant fractions of SOC, and to investigate the depth
distribution and relative proportion of labile and recalcitrant fractions, and their relationship to soil
quality. This study was carried out in five long-term fertility experiments (Gongzhuling,
Zhengzhou, Chongqing, Jinxian and Qiyang) varying in soil type, cropping patterns and agro-
climatic conditions in the arable cropping regions of China. The treatments examined were: (1) No-
fertilization (control); (2) Fallow, where no crop was grown since the initiation of the experiment;
(3) NPK; (4) NPK combined with crop straw (NPKS); (5) NPK with livestock manure (NPKM);
and (6) higher application rate of NPKM (1.5NPKM). Soil samples were collected at 0–20, 20–40
and 40–60 cm depths and analyzed for total SOC, and four fractions of SOC: very labile (Cfrac 1 =
12 N H2SO4), labile (Cfrac 2 = 18 N−12 N H2SO4), less labile (Cfrac 3 = 24 N−18 N H2SO4) and
non-labile (Cfrac 4 = Total SOC−24 N H2SO4). The application of manure and fertilizers increased
the SOC and its fractions when compared with the initial C content of 1990. At Gongzhuling site,
the NPK, NPKS, NPKM and 1.5NPKM treatments increased the SOC content by 14, 17, 54 and
69% in 0–20 cm and 15, 28, 52 and 80%, respectively in 20–40 cm soil layers. The 1.5NPKM had
the highest SOC and its fractions in all five sites. The long-term manure and fertilizers application
decreased the labile: recalcitrant ratio of SOC compared with the no-fertilization control. The SOC
retention was higher in the NPK and manure treated plots compared to control plots. The labile C
pool (Cfrac 1 and Cfrac2) constituted 52–56% and recalcitrant C pool (Cfrac 3 and Cfrac4)
constituted 44–48% of total SOC at all five sites. Manure increases the recalcitrant fraction (Cfrac 3
and Cfrac 4) in deep layer. For Qiyang site, the recalcitrant C fraction was 55% of total SOC at 20–
40 cm in M treatment compared with the surface layer (51%). We concluded that the combined
application of manure and fertilizers has the potential to significantly increase the SOC and its
fractions in agricultural soils of China. The inorganic plus manure fertilizer treatments contained a
larger proportion of total SOC in recalcitrant fraction compared with NPK and no-fertilizer
treatments indicating that manure application helped in promoting the formation of SOC in the
recalcitrant fraction and thus protecting SOC from decomposition losses. The higher
labile:recalcitrant SOC ratio in surface layer than deeper soil layer indicating that improving the
depth distribution may be practical suggestion to achieve C retention.

Ethnopharmacological findings are spread over a multitude of databases and publications and are
not well connected to other biomedical databases. Consequently, the utility of these sources as
knowledge resources are badly limited. It results in a further obstacle for modern day e-science
research, relying mainly on multiple and heterogeneous data sources. Herbal medicines have long
been used for the treatment of different ailments and have attracted the attention of scientists and
common people due to their easy availability, low cost, affordability and minor side effects. Much
research is being performed on the active constituents, protein availability, healing benefits of the
medicinal herbs, their implication in the treatment of multidrug resistant pathogens and other
related properties. Thus, the cataloging of medicinal herbs’ information along with their
DNA/protein sequences has become a fundamental step in the development of new medicinal drugs
against diseases. However, assembly of this information requires proper storage, management and
analyzing tools. This database provides comprehensive information on medicinal properties of
herbs with a stylish web interface. MedHerb database provides quick information access to
medicinal herbs, genes, proteins, plant species, statistical vision, and published literature with
detailed information on each aspect at only one click. Although several medicinal plants have been
tested for different diseases but detailed information on 9 medicinal plant species is available.
Studies are being done to explore other plant species and assemble their all characteristics and will
be added in this database when available. This database encompasses an interactive approach of
Bioinformatics Tools by which users can perform bio-analysis for their different research needs.
Availability of primers is another unique feature of the database assisting in Polymerase Chain
Reaction (PCR) application. The database aims to expand the information by adding new features
like addition of more plant species, expressed sequence tags, therapeutically important information,
more published literature, information on active constituents and new tools to facilitate the
researches from different backgrounds. The database is available at

BIODEGRADABLE PLASTICS PRODUCTION UTILIZING WASTEWATER AS
CARBON SOURCE

Polyhydroxyalkanoates (PHAs) are biopolymers stored in intracellular inclusion bodies by a wide
variety of bacteria as an energy reserve, in response to excess carbon under nutrient-limited
conditions broader usage of biodegradable plastics in packaging and disposable products as a
solution to environmental problems would heavily depend on further reduction of costs and the
discovery of cheap carbon sources as a substrate for bioplastic production. The monomeric
composition of PHAs can be related both to the nature of the carbon source supplied and to the
bacteria. PHAs exhibit great variety of properties and thus may have different applications. The aim
of present study is to check the production of polyhydroxyalkanoates by bacteria using industrial
wastewater as carbon source. Different strategies will be adopted to check the maximum
accumulation of PHA. In this work wastewater was used as a carbon source in different
concentrations. Wastewater was analysed for different nutrients. Total of 30 bacterial strains were
isolated from different water samples. Screening for bioplastic producing strains was done by Nile
blue and Sudan black B staining. Screening for bioplastic producing strains was done by Nile blue
and PHA extraction was carried out at different time intervals using sodium hypochlorite method.
Genomic DNA was isolated to amplify phaC gene and amplified products were submitted for
sequencing after PCR product purification.

The rapid growth of urban population in Faisalabad city of Pakistan from last decades has made
solid waste disposal an important issue and has lead to various environmental problems. This
research aims to contribute into the efforts being made for the solution of this problem. The
Geographic Information System (GIS) approach has been used for the transport route optimization
for the solid waste collection vehicles in Faisalabad city. The locations of solid waste collection
containers, transfer stations and the dumping sites have been marked by using the Google earth’s
imagery. The population density, waste generation and the solid waste services in the entire city
have been spatially analyzed in GIS environment. After measuring the solid waste facility radius,
the different zones have been developed. The best locations for the new transfer stations and
collection containers have also been identified. The road network of the city has been digitized in
ArcGIS software. This resulted into the development of a transport network model for the solid
waste disposal. This model helped in finding the shortest routes from the waste collection
containers to the transfer stations and finally to the main dumping site. This approach could reduce
the time and fuel cost for the solid waste disposal in the city.

Growing population and rapid industrialization has increased the volume of wastewater manifolds
eventually deteriorating the freshwater resources and surrounding environment due to inappropriate
management. Wastewater can be considered as both a resource and a problem. Wastewater and its
nutrient content can be used extensively for irrigation and other ecosystem services. Its reuse can
deliver positive benefits to the farming community, society, and municipalities. However,
wastewater reuse also exacts negative externality effects on humans and ecological systems.
Irrigation of agricultural lands with wastewater led to the accumulation of heavy metals in the soil
and crops grown on it. Variations in the heavy metal concentrations between the vegetables/cereal
crops reflect the differences in uptake capabilities and their further translocation to the edible
portion of the plants. This raises the concern of contamination and bioaccumulation of potentially
toxic elements such as Cd, Cu, Fe, Mn, Pb, and Zn in crops. Pakistan is a case which illustrates this
problem. Both treated and untreated wastewater in the vicinity of large cities like Faisalabad is used
for vegetable production. But, how safe is this practice? How does one tradeoff between the
obvious benefits of this use and the costs associated with it?
