| 6535246141 | photochemical smog | unburned hydrocarbons and NOx from power plants and automobiles react with sunlight to form secondary pollutants: ozone, formaldehyde, etc. Ozone erodes rubber, irritates lungs, and damages plants | 18 | |
| 6535259831 | temperature inversion | -deviation from the normal decrease in temperature as you increase in elevation -results in cooler layer of air being trapped by a warmer layer of air above (warm fronts, mountains) -air quality issues, convection currents cease, traps pollution from an area from being dispersed in a normal manner | 19 | |
| 6535275922 | indoor air pollution | tobacco smoke, radon, formaldehyde, asbestos | 20 | |
| 6535279093 | tobacco smoke | -from cigarettes, pipe, and cigars -particulates-lung cancer, carbon monoxide-shortness of breath, sulfur and carbon dioxide-emphysema, carbon monoxide-heart attack | 21 | |

| 6535318276 | acid deposition | -lower ph as a result of sulfur and water leads to sulfuric acid and nitrogen oxides form nitric acid (wet deposition as rain or fog, dry deposition settles and then later mixes with water) -results in acidification of lakes, killing fish and other marine life -some lakes contain buffers that resist changes in ph; thin soils have less buffer capacity | 30 | |
| 6535333784 | laws and protocols | -montreal protocol -national acid precipitation act -national acid precipitation assessment program -kyoto protocol clean air act | 31 | |
| 6535338107 | clean air act categories | -primary ambient air quality standards (protect health) -secondary ambient air quality standards (ma vs EPA-EPA controls CO2 and other emissions under this act) | 32 | |
| 6535352806 | clean air act pollutants | -criteria pollutants (ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, lead and particulate matter), threaten health, large quantities -hazardous air pollutants-cause cancer or serious health effects | 33 | |
