all types of pollution are explained

2. POLLUTION
Pollution is the addition of any
such constituent to air, water
or land which deteriorates the
natural quality of the
environment.

3. Types of pollution
Air pollution
Water pollution
Soil pollution
Radiation
Noise pollution

4. AIR POLLUTION
• Air pollution means degradation of the
air quality harmfully affecting the living
organisms as well as certain objects.

5. Particulate pollution

6. Gaseous pollution

7. Sources of pollution
Natural sources
• volcanoes
• Storms
Man-Made sources
• automobiles
• industries

8. Vehicular air pollution
The exhausts given out contain
three main gaseous pollutants:
CO2,SO2 and CO.

9. Industrial air pollution
The smoke released by
the factory chimneys
into the air contains lot
of particulate pollutants

10. Burning garbage
The smoke given
out on burning
garbage releases CO2
and some other
harmful gases which
adds to the
particulate air
pollution.

11. Brick kilns
Brick kilns are
fire-heated
enclosures for
making
construction
bricks. Lot of
smoke and
heat given out
are pollutants.

12. Water pollution
• Any change in the water quality which
makes it unsuitable for use by humans
and by other living organisms.

13. SOURCES OF WATER
POLLUTION
Household
detergents
Sewage
Industrial
wastes
Oil spills
Thermal
pollution

14. HOUSEHOLD DETERGENTS

15. SEWAGE
•

16. INDUSTRIAL WASTE

17. OIL SPILLS

18. THERMAL POLLUTION
• Hot waste water released into nearby
streams by industries cause thermal pollution
affecting living organism.

19. SOIL POLLUTION
• Soil contamination or soil pollution is caused
by the presence of xenobiotic (human-made)
chemicals or other alteration in the natural
soil environment.

20. SOURCES

21. SOURCESIndustrial waste
Urban commercial and domestic
waste
Chemical fertilizers
Biomedical waste
pesticides

22. Radiation
• Radiation is a form of energy consisting high
energy particles. It is extensively used in
medical fields and generating electricity.

23. Chernobyl nuclear disaster

24. Noise pollution
• Noise is defined as any disturbing sound.

25. Effects of noise pollution
• Interferes in communication
• Interrupts concentration of thought
• Lowers efficiency
• Disturbs sleeps
• Irritability
• Damage ear drum
• Lead to deafness
• Bird life gets disturbed

26. OTHER EFFECTS OF POLLUTION
• Acid rain
Acid rain is a rain or any other form of
precipitation that is unusually acidic.

27. • Greenhouse effect and global warming
Greenhouse are small houses specially
constructed to grow plants.
Global warming is continuing rise in the average
temperature of Earth's climate system.

28. • Ozone layer depletion
