POLLUTION
Pollution is the introduction of contaminants into the natural environment that cause adverse change.
Pollution can take the form of chemical substances or energy, such as noise, heat or light.
Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.
Forms of PollutionAir pollution
Noise pollution
Soil pollution
Thermal pollution
Water pollution
Plastic pollution
Radioactive contamination

SOIL POLLUTIONSOIL
Soil is the natural medium for the growth of plants.
Soil has also been defined as a natural body consisting of layers (soil horizons) thatare composed of weathered mineral materials, organic material, air and water. Soilis the end product of the combined influence of climate, topography, organisms(flora, fauna and human) on parent materials (original rocks and minerals) overtime. As a result soil differs from its parent material in texture, structure,consistency, color, chemical, biological and physical characteristics.
According to FAO
Soil Pollution
The Soil Pollution is defined as the presence of materials in the soil which are harmful to the living beings when they cross their threshold concentration levels.

Source of Soil Pollution
Acid rain
Excess application of pesticide and fertilizer
Disposal of Industrial waste
Urban solid waste
BIOLOGICAL AGENTS
• The major sources of biological agents
causing soil pollution are human excreta,
animals and birds excreta, municipal wastes,
faulty sanitation.
• The industrial parasites are
among the most threatening
biological agents,
HEAVY METAL POLLUTANTS
• Heavy metal in soil are basically due to industrial discharge.
• E.g.. Zn,Cu,Ni,Cd,As and Pb are also present in significant levels insewage sludge and reach the soil where they become part of life cycleand affects adversely.
Environmental Quality Standards for Soil Pollution

Bio remediation of Soil Pollution
• Microorganisms such as bacteria, fungi & plants to break down of chemicalcompounds that have accumulated in the environment
Pseudomonas fluorescens
HCN → CO2 + NH2
• It is a method that treats the soils and renders them non-hazardous, thus eliminatingany future liability that may result from landfill problems or violations.

Control of Soil Pollution3 Rs: Reduce, Reuse, Recycle
• Reducing chemical fertilizer and pesticide use:
• Applying bio-fertilizers and manures can reduce chemical fertilizer and pesticide use.
• Biological methods of pest control
• Reusing of materials:
• Materials such as glass containers, plastic bags, paper, cloth etc. can be reused at domestic levels rather than being disposed, reducing solid waste pollution.
• Recycling and recovery of materials:
• Materials such as paper, some kinds of plastics and glass can and are being recycled. This decreases the volume of refuse and helps in the conservation of natural resources.
• For example, recovery of one tons of paper can save 17 trees.
• Reforesting:
• Control of land loss and soil erosion can be attempted through restoring forest and grass cover to check wastelands, soil erosion and floods. Crop rotation or mixed cropping can improve the fertility of the land.
• Some other methods using in control of soil pollution
1. Use of pesticides should be minimized.
2. Use of fertilizers should be judicious.
3. Cropping techniques should be improved to prevent growth of weeds.
4. Special pits should be selected for dumping wastes.
5. Controlled grazing and forest management.
6. Wind breaks and wind shield in areas exposed to wind erosion
7. Planning of soil binding grasses along banks and slopes prone to rapid erosion.
8. Afforestation and reforestation.
Application of organic manures, sludge and sewages in field for minimizeof heavy metal presence in soil.
Water is a transparent and nearly colorless chemical substance
Constituent of Earth's streams, lakes, and oceans, and the fluids of
most living organisms.

Water Pollution
• Water pollution is contamination of water bodies .
This form of environmental degradation occurs when pollutants are directly orindirectly discharged into water bodies without adequate treatment to remove harmfulcompounds.
• Water pollution occurs when energy and other materials are released into the water,contaminating the quality of it for other users.
Types of Water Pollution1. Surface water pollution
Found on the exterior of the earth’s
crust ,oceans , rivers and lakes
2. Groundwater pollution
In agriculture sector, used of highly
amount of fertilizer, Pesticides heavy
matal Cd, Pb,Zn Ni are leachable by
heavy rainfall,water logged condition &
high irrigation.
Thermal Pollution
• Thermal pollution is the rise or fall in
the temperature of a natural body of
water caused by human influence.
• Elevated water temperatures
decrease oxygen levels, which can kill
fish and alter food chain composition,
reduce species biodiversity, and foster
invasion by new thermophilic species.
EutroficationRefers to the bloom or great increase
of phytoplankton in a water body due
to the addition of nitrates or
Phosphates from fertilizers or sewage.

How to Control Water Pollution?
1. Keep out fat, grease, or oils from your sink.
2. Do not flush contaminated drugs, liquids, medications, or pills down the drain.
3. Use detergents or bleach minimally.
4. Reduce the usage of pesticides, fertilizers, and herbicides.
5. Ensure proper sewage management and treatment.
6. Do dot dump into any water system directly.
7. Always use environmentally friendly products.
8. Plant trees to reduce the speed of the surface water.
9. Use super energy saving washing machines.
10.Opt for reusable and recyclable options.
11. Avoid the use of plastics.
12. Dispose batteries, antifreeze, and motor oil at specific collection points.
Air pollution• Air pollution is the introduction of harmful substances including particulates
and biological molecules into Earth's atmosphere. It may cause diseases, allergies or death in humans; it may also cause harm to other living organisms such as animals and food crops, and may damage the natural or built environment. Human activity and natural processes can both generate air pollution.

mixture of smoke and fog

Effect on Human, Plant
• Deposition of particulate matter containingtoxic metals affects the growth of plants
• The particulate matter after deposition on plantleaves block stomata opening of plants andreduce plant growth.
• The particulate matter with acid rains ,reducepH of the soil which make the infertile.
Control devices
• In today, increase in pollutant in air (Air pollution) we need to control of this pollution and balance of ecology with the control devices
• control devices is used in air clean from present pollutant in air .
• different types of control devices like
• Electrostatic precipitators
• dust cyclones
• Baghouses
• Dust collector
Control devices• Electrostatic precipitators
• Is a particulate collection device
• that removes particles from a flowing gas(such as air), using the force of an induced
electrostatic charge.
• The emanating dust is charged with ions
and the ionized particulate matter is
collected on an oppositely charged surface.

Baghouses• heavy dust loads, a dust collector
• consists of a blower, dust filter, a
filter-cleaning system, and a dust
receptacle or dust removal system
(distinguished from air cleaners
which utilize
disposable filters to remove the dust).
https://www.britannica.com/technology/baghouse-filter
Control of vehicular pollution :
• The price of diesel is much cheaper than petrol which promotesuse of diesel.
• To reduce emission of sulphurdioxide, sulphur content in dieselhas been reduced to 0.05%.
• Earlier lead in the form of tetraethyl lead was added in thepetrol to raise octane level for smooth running of engines.
• Addition of lead in petrol has been banned to prevent emissionof lead particles with the vehicular emission.
Conclusion Soil, Water & Air Pollution control in today is most necessary for balance ofecosystem in future life in any sector . Managing of ecology with minimum use ofpetrol on automobiles, industrial plastic material ,chemical fertilizers ,Pesticides infield . Higher amount of afforestration those control of Soil , Water and Air pollution.
Because We are depends on natural ecological system balance So, we work maintainthe ecosystem of the earth and happies for future life or generation .
Soil ,Air & Water is most important for balance of ecosystem
''When will Unbalance Ecosystem of earth,We will can't survive in the earth ''
