What is Air Pollution |
Presence of chemicals in the atmosphere in high enough concentration to do harm to organisms, ecosystems, or climate |
|
|
Primary Pollutants |
Chemicals emitted directly into the air |
|
|
Secondary Pollutants |
Harmful chemicals formed by reactions of primary pollutants |
|
|
Major Air Pollutants: Carbon(2) + Sources |
1. Carbon Monoxide: vehical exhaust, burning of forest, tobacco smoke 2. Carbon Dioxide: Majority resulted from natural carbon cycle. Remaining from burning fossil fuels and clearing forest |
|
|
Major Air Pollutants: Nitrogen + Component of |
Nitric Oxide and Nitrogen Dioxide: Component of photochemical smog Nitric Acid: Component of Acid decomposition |
|
|
Major Air Pollutants: Sulfur |
Sulfur Dioxide: Majority from combustion of coal |
|
|
Major Air Pollutants: Particulates + Natural and Human Examples |
Solid and liquid particles light enough to remain suspended in air Natural: Sea Salt Human: Tobacco Smoke, Coal, Vehicles. |
|
|
Major Air Pollutants: Ozone |
Major component of photochemical smog. In troposphere (closer to earth), it is bad. In stratosphere, it is considered good. |
|
|
Industrial Smog (Grey-air smog) |
Product of Coal |
|
|
Photochemical Smog (brown smog)? Formed By? |
Mixture of primary and secondary pollutants catalyzed by UV Radiation Formed by nitrogen, sun, heat, and organic chemicals |
|
|
5 factors that reduce air pollution |
Gravity, Precipitation, Salty sea spray, winds, chemical reactions Does not make it go away, it spreads to somewhere else. |
|
|
3 factors that increase air pollution |
Urban buildings, Hill and mountains, high temp |
|
|
Indoor Air Pollution in Developing Countries |
Burning of biofuels indoors w/ poor ventilation |
|
|
Indoor Air Pollution in Industrialized Countries |
Polluted air from traffic-clogged areas get trapped inside the house and people keep breathing that in without windows open. |
|
|
Health Impacts of Air Pollution (2) |
1. Increase in bronchitis and asthma 2. Reduced blood's ability to transport blood |
|
|
Law |
Made by legislative body (Congress) |
|
|
Regulation |
Made by executive branch which sets limits made by law - FDA, EPA, USDA |
|
|
Clean Air Act |
EPA sets limit on hazardous air pollution and states must adopt enforceable plans to meet standards |
