3. Pollution is the addition of the contaminants to the natural environment which
causes adverse changes.
Pollution
Air pollution is the outcome of any change in the composition of air, either by
physical or chemical methods that cause harmful effects on health.

5. • Natural sources
• Man-made sources

6. Forest Fire Volcanic Eruptions Dust Storm
Natural sources causing Air pollution

7. Airplane pollution Vehicle causing pollution Factories causing pollution
Spray causing pollution
Power plant causing pollution
Man – made sources of Air Pollution

9. S.NO. NAME OF THE
AIR POLLUTANT
SOURCES EFFECTS
1. Carbon monoxide
(CO)
Combustion of fuels Formation of
Carboxyhaemoglobin. It may
lead to death.
2. Carbon dioxide
(CO2)
Burning of Coal/
timber
Leads to Global warming
3 Nitrogen oxides
(NO2)
Automobile exhausts Causes Acid rain
4. Sulphur dioxide
(SO2)
Burning of Sulphur. Causes irritation to eyes, lung
cancer and asthma.
Few Air Pollutants and their effects on human health and environment

11. It irritates the eyes and the skin of
human beings.
It inhibits germination and growth of
seedlings.
It affects the fertility of soil, destroys
plant and aquatic life.

13. Use of Crude oil should be avoided.
Use of automobile should be reduced.
Industrial smoke should be filtered before
releasing into the atmosphere.
Reducing the content of Carbon dioxide in
the environment.
 Planting of more trees to get pure air.
