Ch. 15 Air Pol Pt. 1

Environmental Ecology- Air Pollution

Troposphere First 0-11 miles. 80% Earth's air, most air pollution
Stratosphere 11-31 miles. Lower portion is the ozone
Good Ozone Filters 95% of UV rays Occurs in lower portion of stratosphere
Bad Ozone Very reactive- produces photochemical ozone Occurs in lower portion of stratosphere
Air Pollution Chemicals in the atmosphere in a high enough concentration to produce harm: 1. Living Organisms 2. Damaged Ecosystems 3. Climate effect 4. Damage to physical structures
Primary Pollutants Discharged directly into the air from human activities
Secondary Pollutants Chemicals that react with primary pollutants and other air components.
Major Air Pollutants 1. Carbon Monoxide (CO) 2. Carbon Dioxide (CO2)
Carbon Monoxide (CO) Colorless, odorless, tasteless, deadly gas. Comes from incomplete combustion of fossil fuels that contain carbon.
Carbon Dioxide (CO2) Colorless, odorless, greenhouse gas related to atmospheric warming. Greater than 90% comes from natural sources (volcanos) Man sources about 7%
