Introduction• Background:

o Cement plant is a significant source of air pollution because ofuse of clinker, gypsum, silica etc. during manufacturing

o Exposure to cement dust, at workplace and among the residentsin adjoining areas cause adverse health effects

o Annual decrease in lung function results due to dust exposure

o In addition to Cancer and pulmonary disorders, skin diseases arealso found among employees in dust related industrial settings

o The skin diseases cause appreciable impact on the quality of lifeand may increase the body burden of toxicants for workers

4



Research Problem

• Cement plant is located in outskirts of Islamabad.

• Cement industry neighborhoods close to cement plant are

constantly exposed to cement manufacturing dust and fumes.

• This study explains the effects of cement plant on nearbypopulation.

5



Objectives

• To evaluate the amount of cement dust fall on the residential placesof surrounding areas of cement plant

• To find health effects on nearby population at different distancesfrom cement industry and their health condition

6



Literature Review• Problems due to Cement Industry

o The prevalence of respiratory and chronic bronchitis symptoms to besignificantly higher in cement workers than in controls, both among smokersand non-smokers (Kalacic, 1973).

o Atmospheric dust is an important source of air pollution, mainly in dry climates.It contains high concentrations of many metals which have toxic effects onplants, animals and Humans

o They include specific problems about odors, blasting, noise, respiratoryproblems. (Abdul-Wahab, 2006).

o The CO2 emissions from cement plants are next to the coal based thermal powerplants.

o On the global scale the cement industry is responsible for 20% of the man-madeCO2 emissions.

o This contributes to around 10% of the man-made global warming potential

(Anandet al., 2006) 7



Research Methodology• Study Area:

o This study will be carried out in Askary cement industry, Wah (Islamabad)

o The map of study area is shown in figure in next slide which specifies thelocation of cement industry near Islamabad

o This study is designed to find health effects of cement industry onsurrounding population of Wah, near Islamabad, where cement industry islocated from last many years.

o All crushing and grinding process are carried out at same place

o Residence of people are not much far from plant which is harmful for them.Different locations are selected based on specific distance from the source asshown in figure.

Methodology

• Dust samples will be collected in residential areas from south side ofcement industry.

• These samples will be collected on plastic sheets from the roofs ofresidential area across cement plant.

• Population surveys will be carried out from surrounding cement plant anddisease ratio will be computed in residential areas by using questionnaireor oral interviews which will determine the ratio of health effects in people

living nearby

• Distance will be measured by using “Pro distance measured aps” frommobile. Four different locations are selected on the base of distances fromthe plant to collect the samples and questionnaires. First distance is 50m,second is 100m, third is 150m and fourth is 200m away from cement plant.

9



Cont..• Questionnaire will be filled by taking information from the people

living in that area by interviewing them and observing their attitude.

• All interviews will be conducted face to face, in Urdu or in their nativelanguage.

• At the beginning of the interview the objectives of the study will beexplained to each participant and their informed verbal consent will beobtained.

• Data will be analyzed using SPSS. Frequencies, percentages, means andstandard deviations will be calculated for appropriate variables.

• Secondary data is to be collected by using different sources like articlesreviews, research reports, books, different regulations and other data

base.

Expected Outcome• The ratio of mean value of cement dust samples collected from nearer

location is expected to be higher than the other location

• Diseases prevalence ratio from population near cement plant is expected to be much higher as compared to other location.

• The location adjacent to the industry road is expected to have a dust fallpattern a little higher because of loading trucks of cement.

• They are expected to cause health effects like skin problems and eyes

problems which may differ by other locations.

• In a location farther from cement plant, population response towarddiseases is likely to be more less because cement dust fall pattern may below in that area.
