AIR POLLUTION AIR POLLUTION
Air pollution is the addition of pollutants to the air which has
negative effects on the environment.
The example of air pollution caused by human activities:
Industrial activities
Rubbish burning
Smoke emission
from motor vehicles
Agricultural activity
Acidic gases
Sources of air pollutants:Burning of fossil fuels by
factories

Effect:Dissolves in the rain to
form acid rainCorrodes iron objects
Damages our breathing tubes and lungs.

Steps to prevent:Encouraging the use of a
system to clean the air which dissolves the acid
gases before they are released into the
atmosphere

Carbon manoxideCarbon manoxide
The effect:Reduces the ability of
blood to transport oxygen, resulting in
deaths

What can we do to prevent and control air pollution???
What can we do to prevent and control air pollution???
Use public transport when available. Join a carpool. Use bicycles instead of motor vehicles.
Plant more trees in your surroundings.Avoid open burning. Burn plastic waste in
incinerators.
