atmospheric air zones |
troposphere and stratosphere |
|
|
0-11 mi, 80% most pollution and air |
troposphere |
|
|
11-31 mi, lower ozone layer |
stratosphere |
|
|
shields life on earth from UV |
good ozone |
|
|
air pollutant damages human health, vegetation and many common materials (photochemical ozone) |
bad ozone |
|
|
chemicals in air that harm living organisms, ecosystems, climate condition, and physical structures |
air pollution |
|
|
emitted directly from human activity |
primary pollutant |
|
|
chemicals have reacted with other chemicals in air |
secondary pollutant |
|
|
colorless, odorless gas, very toxic, incomplete combustion fossil fuels, cigarette smoke |
carbon monoxide (Co) |
|
|
colorless, odorless gas, natural (>90%) and man made (7%) sources, greenhouse gas -traps heat |
carbon dioxide (Co2) |
|
|
primary pollutant, highly reactive with other air pollutants, fossil fuels (coal burning, lighting-natural) |
nitrogen oxide (No) |
|
|
reddish brown gas |
