This document discusses environmental pollution and protective measures. It defines environmental pollution as any undesirable change in the physical, chemical, or biological characteristics of air, water, and soil that may harm living organisms. It identifies different types of pollution like air, water, and land pollution. It then lists various pollutants and sources of pollution like automobiles, thermal power stations, industry chimney wastes, domestic and industrial wastes. The document discusses how pollution destroys the environment and affects health. It provides some protective measures that can be taken like using cleaner technologies and fuels in industries and vehicles, treating sewage water before discharge, reducing waste, and enforcing environmental laws.

8. Environment Pollutants
Deposited Matter:
Soot, Smoke, Tar, Grit etc.
Gases: Oxides of Nitrogen, Carbon monoxide, Sulphur 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.
Radioactive Wastes: Atomic Energy Waste.
Radiation Pollution: Nuclear Energy Recourses, Mobiles etc.

9. Pollution destroys all the components of
environment that sustain life on earth.
Soil, we cultivate
Air,
we breathe
Water, we drink
Food, we eat

11. AIR POLLUTION SOURCES
Automobiles and
Generators
Thermal Power Stations
Fossil Fuels
Industry Chimney Wastes
Effects: Respiratory infections, Lung diseases, Skin allergies,
Anxiety, Irritation to eyes, nose & throat.

12. Vehicular Emission: CNG, Fuel feeding, Catalytic filters,
Motor Vehicles act.
Ind. Pollution: Technologies to check and destroy particles
released by industrial plants
Noise Pollution: By planting more trees to reduce sound levels,
Nuisance check squads, silencing devices etc.

14. 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.

15. 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.

17. Agricultural and forestry
Drainage
Deforestation
Effects: Depletion of fertile top soil, Extinction of flora etc.

18. Self Restrain: Judicious exploitation and use of natural resources
Awareness
Education & Legally

19. Peoples’ participation
