Air pollution is the introduction of particulates, biological molecules, or other harmful gases into Earth's atmosphere, causing disease, death to humans, damage to other living organisms such as food crops, or the natural or built environment. Air pollution may come from anthropogenic or natural sources.

3. WHAT IS AIR POLLUTION??
• Airpollution is the introductionof chemicals,
particulatematter, or biologicalmaterials that cause
harm ordiscomfort to humans or other living
organisms, or cause damage to the natural
environmentor built environment,into the
atmosphere.

4. TYPES OF AIR POLLUTION
• There are several types of air pollution, Mainly Indoor
Air Pollution and OutDoor Air Pollution. These
include smog, acid rain, the green house effect and
hole in the ozone layer.
• Onetype of air pollution is the release of particles into
the air.
• Anothertype of pollution is the release of poisonous
gases.

5. • Smog is a type of large scale outdoor
pollution. It is caused by chemical reactions
between pollutants derived from different
sources.

6. ACID RAIN
It is caused when a pollutant
combines with droplets of water
in the air.
The effects of acid rain on the
environment can be serious

7. EFFECTS OF ACID RAIN
 Acid rain causes acidification of lakes and streams
.
 It contributes to the damage of trees and many
sensitive forest soils.
 It accelerates the decay of building materials and
paints, including irreplaceable buildings, statues,
and sculptures that are part of our nation's cultural
heritage.

8. GREEN HOUSE EFFECT
• It generally comes from the build up of
carbon dioxide gas in the atmosphere.
• Carbon dioxide is produced when fuels are
burnt.
• In this type of pollution sun rays go to
the atmosphere and they are trapped by
green houses gases. So the temperature on
the earth raise.

9. It is another result of air pollution.
Chemicals released by our activities affect the stratosphere.
Release of CFC from heating, aerosol cans , refrigerator equipments
removesomeof the ozone , causing “ HOLES” .

10. CAUSES OF AIR POLLUTION
Dust raised on the ground during dust
storms.
Stone dust raised by crushing of stones
in quarries.
Smoke emitted by vehicles.
Smoke from forest fires.

11.  Smoke raised by burning of coal in
powerhouses.
 Burning of wood, cow dung cakes, garbage
etc.
 Germs from coughing and sneezing.

12. Some individuals are much more sensitive to pollutants
than are others.
Air pollution can affect our health in many ways with
both short termand long termeffects.
Many different chemicals in the air affect the human
body in negative ways.
• Older peopleare highly vulnerable to diseases induced by
air pollution. Those with heart or lung disorders are
under additional risk

13. Many different chemicals in the air affect the
human body in negative ways.
• Children and infants are also at serious risk.
• Air pollutants such as ozone, nitrogen oxides, and
sulfur dioxide also have harmful effects on natural
ecosystems. They can kill plants and trees by
destroying their leaves, and can kill animals,
especially fish in highly polluted rivers.

14. PREVENTIONS
 Car Pool: Forming and implementing a car
pool will reduce the number of cars, thereby,
preventing air pollution by cutting down the
use of fossil fuels. This way, it will help in the
sustainable use of fossil fuel and its
conservation for the future generations.

15. PREVENTIONS
 Vehicle Care: Timely servicing of the car
helps to keep it in a good condition, and also
minimizes fuel exhaust. Driving the car at an
average speed and turning off in traffic are
the thumb rules to save fuel. Make sure to
use unleaded petrol and opt for regular
pollution checking of your car.

16. PREVENTIONS
 Public Transport: Whenever possible, try to
travel by public transports. This helps in two
ways; prevents air pollution and increases
public income. If you are going to a nearby
place, go by walking or use a bicycle, instead
of using your vehicle. The objective is to
minimize the use of fuels as far as possible.

17. PREVENTIONS
 Saving Energy: Saving energy will, of course,
help to prevent air pollution. Switch off the
lights, fans, air conditioners, televisions, and
other appliances, when not in use. You can
also share a room with others when the air
conditioner or fan is on, instead of switching
them on in every room.
