PROBLEMS OF AIR
POLLUTION

14. Water Pollution
Soluble effluents and
inorganic components
increasing in the water
content.
Decreasing the level of
Oxygen molecule in the

15. WATER POLLUTANTS
• Household Wastes,
• Domestic Wastes,
• Industrial Effluents,
• Agricultural Manures, (Inorganic)
• Pesticides,
• Thermal station waste water, etc.,

16. Increasing Salt content,
BOD, (Biological Oxygen
Demand)

17. Nutritional imbalance or
Lack of Microorganisms or
Degradation of soil texture.

18. Soil Pollutants
•House holding Wastes,
•Inorganic Manures,
•Pesticides,
•PVC Pipes,
•Polythene bags,
•Crackers, etc.,

19. Problems of Soil Pollution
Soil erosion.
Decreased Soil Water level.
Soil infertility. Etc.,

20. Noise Pollution
Above frequency of 20 Hz to
20000 Hz is audible sound,
more than that we called
Noise.
