ATMOSPHERE AND ENVIRONMENT
Composition Of Gases Present In Dry Air
Oxygen 21%
Noble Gases and Carbon Dioxide 1%
Nitrogen 78%
Common Atmospheric Pollutants
Nitrogen Oxides
Ozone
Methane
Sulfur Dioxide
Carbon Monoxide
Unburned Hydrocarbons
Sources Of These Pollutants
Nitrogen oxides from lightning activity and internal combustion engines
Sulfur dioxide from volcanoes and combustion of fossil fuels
Carbon monoxide from incomplete combustion of carbon-containing substances
Effects Of Pollutants On Health And Envoirment
Nitrogen dioxide and Sulfur dioxide causes acid rain and breathing difficulties
Acid rain is formed when acidic air pollutants such as sulfur dioxide and nitrogen dioxide dissolve in rain water.
Formation of Acid Rain
Sulfur dioxide gas dissolves in water to form sulfurous acid (H2SO3).
Carbon monoxide form a stable compound which prevents oxygen from being transported
Causing headaches and breathing difficulty which leads to death
Possible Ways To Minimize Air Pollution
Participate in your local utility's energy conservation programs.
Conserve energy , turn off appliances when not in use
Limit driving , use public transportation , walk or cycle
Run dishwashers and clothes washers only when full
Avoid excessive idling of your automobile.
