1. Composition of air.

1.1. Contain 79% of nitrogen

1.1.1. Give proteins to plants Animal eat plants for protein.

1.2. Contain 20% of oxygen

1.2.1. Help to decompose

1.2.2. needed to LIVE!!!

1.3. Contain 1% of other gases

1.3.1. Carbon dioxide.

1.3.2. noble gases

2. Pollutants in air

2.1. Carbon monoxide,

2.1.1. Causes Incompletion of combussion of carbon substances such as fossil fuels. Forest fire

2.1.2. Harmful effect headache Breathing difficulties Damage to heart if taken too much, will cause death

2.1.3. Solution, avoid in complete combustion of fossil fuels Use better burner Add catalytic converter to exhausts of motor vehicles

2.2. Sulfur dioxide

2.2.1. Causes Valcanoes combustion of fossil fuels

2.2.2. Harmful effects Cause breathing difficulties asthma attack Acid rains

2.2.3. Solutions Use fuels which have little sulfur contents Use calcium hydroxidxe to remove sulfur dioxide. Calcium sulfate and water will be formed Use lesser coals Because it contains sulfur Should be process first to remove sulfur contents

2.3. Nitrogen oxide

2.3.1. Causes Lightning activities Power station Internal combustion engines Consist of nitrogen and oxygen

2.3.2. Harmful effect breathing difficulties Lung damage Acid rain Creates ground level ozones when reacts with hydrocarbon

2.3.3. Solution Use catalytic in car

2.4. Ground level ozone

2.4.1. Causes Reactions between unburned hydrocarbon and nitrogen oxides in strong sunlight

2.4.2. Harmful effect eye irritation damageg lung tissues

2.4.3. Solution Reduce nitrogen oxide and hydrocarbon

3. Acid rain

3.1. Causes

3.1.1. Sulfur dioxide and nitrogen oxide When Sulfur dioxides and nitrogen oxide reacts with oxygen and water, sulfuric acid and nitric acid is form

3.2. Harmful effects

3.2.1. Acid rains cause acidification in streams and river kill fishes Make reprodution a failure

3.2.2. Acid rains accelarates the decay of building

3.3. Solution

3.3.1. Reduce sulfur dioxides and nitrogen oxides
