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
