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

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

Step to prevent:Installing instruments that can change carbon manoxide to carbon dioxide e.g catalytic

converters in car exhaust pipes

Chlorofluorocarbon (CFC)

The effect:Cause cancer of the skin and cataracts in

the eyes.Destroy the body’s

immune system.

Steps to prevent:Reducing the use of chlorofluorocarbon material.

Sources of air pollutants:

Steps to prevent:Educating the

public about the dangers of smoking.

Prohibiting the public from smoking

in public areas.

Life without clean air.

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.
