Presentation Transcript

  1. AIR POLLUTION

  2. Air Pollution created by man Burning of Fossil Fuels • Examples of fossil fuels: Oil and coal

  3. Burning of fossil fuels produces harmful gases known as OXIDES

  4. Air Pollution created naturally Dust Volcanic Ash Forest Fires Sea Salt

  5. Types of Pollution Primary Pollutants Car exhaust (carbon monoxide)

  6. Industrial Smoke

  7. Volcanic Ash

  8. Secondary Pollution Created when primary pollutants mix with natural chemicals in the air. Examples: Smog

  9. Ozone

  10. Acid Precipitation • Chemicals from burning fossil fuels are absorbed in the clouds. • Clouds release acid rain or snow, which harms animals, trees, and pollutes water supplies.

  11. Ozone Layer • Protects us from ultraviolet radiation • Broken down by the chlorine in chlorofluorocarbons (CFC’s). CFC’s found in aerosol sprays and as a refrigerant. • Chlorine takes breaks apart the three oxygens that make ozone • Ozone is made again by oxygen combining with ultraviolet radiation

  12. Health affects of Air Pollution

  13. 1. Coughing • 2. Dizziness • 3. Lung Disease • 4. Runny Nose

  14. Environmental Protection Agency • Controls amount of air pollutants released by any source • Created by Clean Air Act, passed by President Nixon in 1970 • EPA requires industrial plants to use Scrubbers, which take harmful pollutants out of smoke
