Contd.
Environment Pollutants
Deposited Matter: Soot, Smoke, Tar, Grit etc.

Metals: Lead, Mercury, Zinc, Iron, Nickel etc.
Agro Chemicals: Pesticides, Herbicides, Bactericides etc.
Solid Wastes: Plastics, Polythene, Glasses etc.
Noise: Industries, Vehicular, Domestic etc.

Pollution, its Kinds and Pollutants
Why Protection ?
Pollution destroys all the components of environment that sustain life on earth.
Soil, we cultivate
Air, we breathe
Water, we drink
Food, we eat
AIR POLLUTION SOURCES
Automobiles and GeneratorsThermal Power StationsFossil FuelsIndustry Chimney Wastes
Effects: Respiratory infections, Lung diseases, Skin allergies, Anxiety, Irritation to eyes, nose & throat.
Protective Measures
Vehicular Emission: CNG, Fuel feeding, Catalytic filters, Motor Vehicles act.Ind. Pollution: Technologies to check and destroy particles released by industrial plantsNoise Pollution: By planting more trees to reduce sound levels, Nuisance check squads, silencing devices etc.
WATER POLLUTION SOURCES
Biological: Domestic wastes, Solid wastes,
Ind. Wastes and Effluents: Heat and Radio Active Substances from thermal power plants.
Agricultural Discharges: Fertilizers and Pesticides through rain and irrigation via drainage pattern
Effects: Diseases like Flurosis, Cholera, Diarrhoea, Jaundice etc.
Protective Measures
Recycling of sewage water and treatment of water before discharging into water bodies.
Reducing the waste input
Re-utilization of waste
Removal of Pollutants using technologies.
LAND POLLUTION SOURCES
Agricultural and forestry
Drainage
Deforestation
Effects: Depletion of fertile top soil, Extinction of flora etc.
Protective Measures
Self Restrain: Judicious exploitation and use of natural resources
Awareness
Education & Legally
SOME OTHER PROTECTIVE MEASURES
