Air PollutionAir Pollution
Most air pollution is the result ofburning fossil fuels…….
• Coal
• Oil
• Gasoline
• Diesel fuel
• ½ of the air pollution comes from cars that burn gas and diesel.
• ¼ comes from factories and power plants that burn coal and oil.
This forms 2 main types of air pollution
and
SMOG• Today most cities experience
photochemical smog, caused by the action of sunlight on chemicals.
How smog is formed…..
• Nitrogen combines with Oxygen = nitrogen oxides.
• Nitrogen oxides combine with hydrocarbons (from burning fossils fuels).
• In the presence of sunlight they form a mix of chemicals called photochemical smog.
SMOG FORMATION
Harmful Effects of Photochemical Smog
• Lung irritation-
• Harmful to plants
• Damages paint, rubber, and some plastics.

ACID RAIN•Rain is naturally slightly acidic, but rain that contains more acid than normal is known as acid rain.
ACID RAIN
• The smoke and fumes from burning fossil fuels rise into the atmosphere and combine with the moisture in the air to form acid rain.
• The main chemicals in air pollution that create acid rain are sulfur dioxide and nitrogen oxides.
• This forms a mild solution of sulfuric acid and nitric acid.
• Rainwater, snow, fog, and other forms of precipitation containing those mild acids fall to the earth as acid rain.
ACID RAIN FORMATION
Harmful Effects of Acid rain
• Damaging to buildings and statues.
• Harmful to plants, especially pine trees.
• Harmful to lakes and ponds. Acid rain can make water so acidic that plants, amphibians, fish, and insects can no longer survive in it.
• Can even be harmful to human health.
Damage done by Acid Rain
In Conclusion……
• Burning fossil fuels can create both photochemical smog and acid rain.
• They are both harmful to people and the environment.
