Air Pollution Main types of air pollution Indoor air pollution Main causes for the air pollution How the air pollution effect our planet How can we help to not cause more air pollution

1. Air Pollution

3. What are the main types of air pollution?
• Smog
• Acid Rain
• Green House Effect
• Hole in the Ozone Layer

4. • Smog
-Smog is a type of
large-scale outdoor
pollution. It is
caused by chemical
reactions between
pollutants derived
from different
sources.
-Cities are often
centers of these
types of activities.

5. •Acid rains
-It’s caused when a pollutant
combines with droplets of
water in the air.
-The effects of acid rain on
the environment can be very
serious.

6. •Greenhouse effect
-It generally comes from the build up of carbon dioxide gas in
the atmosphere. Carbon dioxide is produced when fuels are
burned.
-In this type of pollution sun rays go into the atmosphere and
they are trapped by greenhouse-gasses. So the temperature on
the earth raise.

7. • Hole in the ozone layer
-It’is another result of pollution. Chemicals
released by our activities affect the stratosphere.
-Releases of CFC from heating, aerosol cans,
refrigerator equipment removes some of the
ozone, causing "holes”.

8. • It’s more
dangerous than the
outdoor pollution,
because we do
everything in
enclosed
environments where
air circulation may
be restricted.
• There are many
sources of indoor
air pollution:
tabacco smoke,
cooking and heating

9. What are the main causes for the air pollution
by human activities?
• Factories
• Automobiles
• Energy sources

10. A view of a Cement Plant in Karachi

11. Smog and reduced visibility in the atmosphere
of Karachi due to air pollution

13. •Global warming
•Respiratory disease
•Pants die

15. Implementation of Public Transport
System

16. Improved road network by means of
a network of flyovers

17. Conversion of vehicles to CNG buses

18. Control on the entry of older &
polluting vehicles in to urban areas

19. Gasoline lead phase out program

20. Diesel sulphur phase out program

21. Use safe cars
And

22. Plant more trees

23. conclusion
If everyone would
help to save the
earth we would
live in a safe
environment!
