Ch. 15 Air Pol Pt. 3
Environmental Ecology- Air Pollution
Term | Definition |
---|---|
Air quality issues causes... | 3 million deaths per year |
1970 Clean Air Act | Mandated EPA establish and enforce 6 Ambient Air Quality standards and established 188 Hazardous Air Pollutants (HAPs) |
Ambient Air Quality Standards | 1. Carbon Monoxide (CO) 2. Nitrogen Oxide (NO2) 3. Sulfur Dioxide (SO2) 4. SPM (Suspended Particulate Matter) 5. Photochemical Ozone (O3+Chemicals-->bad ozone) 6. Lead (PB) |
New cars... | Produce 75% less air pollution due to catalytic converters |
Greatest Air Pollution | ...Occurs in the home 2-5x more air pollution |
Global Warming | Should be looked at in different regions, not on global scale. Is a scientific consensus, not scientific proof |
Natural Greenhouse Gasses | 1. O2 2. H2O 3. CH4 (Methane) 4. N20 (Nitrous Oxide) Natural sources that control temp by trapping heat |
Human Sources | 1. Ag 2. Deforestation 3. Fossil fuels |
Harmful Effects of Atmospheric Warming | 1. Snow & Ice Melt 2. Oceans Rising 3. Disruption of Ocean Currents 4. Extreme Weather 5. Biodiversity Changes 6. Crop Growth locations shifted 7. Health Effects/Diseases 8. Permafrost Melt 9. Reduced Food Productivity-drought |
