Air Pollution

Any contamination of the air Air Pollution Any contamination of the air Can be caused by humans or nature

Pollution that is put directly into the air Examples: Car exhaust Factory waste Volcanic ash Primary Pollutants

Created when primary pollutants mix with water or sunlight Secondary Pollutants Created when primary pollutants mix with water or sunlight Examples Acid rain Smog

Human caused air pollution Industrial Factories, manufacturing, power company Indoor Cleaners, heaters, insulation, carpeting, furniture

water that has been mixed with primary pollutants in the air, then rains down Acid Rain

Effects of Acid Rain Soil Plants Waterways Washes away the good parts of soil, leaving more acidic materials behind Plants Can destroy large regions, plant growth altered or destroyed Waterways Increased acid in water causing Acid Shock of plants and animals living in or by water

Effects of Air Pollution on People Lung cancer Asthma Heart disease Irritation of eyes, nose, throat

Cleaning Up the Air Clean Air Act Law that limits amounts of pollution allowed EPA Environmental Protection Agency Part of government to oversee laws on pollution Scrubbers Remove pollution before it is released back into environment Lifestyle changes Walk, cleaner fuel, carpool Cleaning Up the Air
