This document discusses various types of pollution including air, water, noise, and soil pollution. It provides details on the sources and effects of air pollution, noting that air pollution is one of the most common and dangerous types of pollution. The document outlines both natural and human-caused sources of air pollution and their negative impacts such as global warming, ozone depletion, and acid rain. It emphasizes the importance of reducing air pollution through individual actions like conserving energy and planting trees.

P OLLUTION

3. A IR P OLLUTION
 Air pollution is perhaps the most
common and the most dangerous type
of pollution. It involves the direct
release of chemicals into the
environment. The chemicals then
become the part of the air around us
that all the living things take in.

4. W ATER P OLLUTION
 The 75% of the earth’s surface is covered with
water and more that half of the total population
of earth’s species resides in water.
 Moreover, our life greatly depends on water and
life without water is impossible. Water pollution
not only affects the fish and animals living in the
water but also affects the whole food chain by
also transferring the contaminants to the
consumers depending on these animals.

5. N OISE P OLLUTION
 Unlike other the above mentioned types of
pollutions does not involve hazardous
chemicals or their incorporation into the
environment, rather noise pollution is the
increase in the rate of noise in the
environment.
 Noise can be extremely dangerous. And it is
all around us. It penetrates into human mind
and controls it.

6. S OIL P OLLUTION
 Soil pollution involves the
contamination of soil by the release of
harmful substances into the soil.
Unlike air pollution, which has a direct
affect on human lives, soil pollution
causes an indirect damage to humans
and other animals.

7. W HY I S A IR P OLLUTION
B AD ?
 Everybody even the children know that
air pollution is bad but how it is bad
and what effects it can bring to
humans or to other aspects of the
environment is a million dollar
question. The whole story of air
pollution revolves around the hazards
that it is capable of causing to the
atmosphere.

8. S OURCES
 Sources of air pollution refer to
the various locations, activities or
factors which are responsible for
the releasing of pollutants into
the atmosphere.

9. A NTHROPOGENIC SOURCES
( HUMAN ACTIVITY )
 "Mobile Sources" include motor vehicles,
marine vessels, aircraft and the effect of
sound etc.
 Military, such as nuclear weapons, toxic
gases, germ warfare and rocketry
 FROM FIRE THE FOREST.
 FROM USE OF Chemicals.

10. S OURCES AND M ETHODS
BY HUMAN
 motor vehicle exhaust
 industrial processes
 auto manufacturing
 building demolition
 fuel production
 roadway construction

11. A IR POLLUTION IN INDIA
 Air pollution is high in Indian cities.
 Indian cities are polluted by vehicles and
industry emissions. Road dust due to vehicles
also contributing up to 33% of air
pollution[12] In cities like Bangalore, around
50% of children suffer from asthma.[13] India
has emission standard of Bharat Stage IV
(Euro IV) for vehicles since 2005.

12. W HO; DATA ABOUT
A IR P OLLUTION
 The World Health Organization
estimates that about two million
people die prematurely every
year as a result of Air pollution
, while many more suffer from
breathing ailments, heart
disease, lung infections and even
cancer.

13. W ORLD DATA FOR AIR
P OLLUTION

14. W HAT IS GLOBAL WARMING ?
 Global warming is when the earth
heats up (the temperature rises). It
happens when greenhouse gases
(carbon dioxide, water vapor, nitrous
oxide, and methane) trap heat and
light from the sun in the earth’s
atmosphere, which increases the
temperature.

15. WAYS YOU CAN REDUCE AIR
POLLUTION ?
 Conserve energy - turn off appliances
and lights when you leave the room.
 Recycle paper, plastic, glass bottles,
cardboard, and aluminum cans.
 Plant deciduous trees in locations
around your home to provide shade in
the summer, but to allow light in the
winter.

16. WAYS YOU CAN REDUCE AIR
POLLUTION ?
 Connect your outdoor lights to a timer or use
solar lighting.
 Wash clothes with warm or cold water instead of
hot.
 Buy rechargeable batteries for devices used
frequently.
 Choose efficient, low-polluting models of
vehicles.

17. E FFECTS FROM A IR P OLLUTION
 Global warming
 Ozone depletion
(Ozone hole)
 Acid Rain

18. PLANT TREE
 TREE reduce the air
pollution in the world.
 It also reduce the global
warming.
 PLANT A TREE AND
CONTRAL THE
POLLUTION
 IT IS A GOOD SOCIAL
WORK…
