AIR POLLUTION (2) : AP Environmental Exam - Studying Flashcards
Indoor air pollution is more severe and deadly than…
outdoor air pollution
Indoor air pollution occurs more frequently in….
rural areas, as indoor burning is common
Modern buildings, however, can still suffer from indoor air pollution
Primary Pollutant
Pollutants being DISCHARGED INTO the troposphere
ex:
CO2 - carbon dioxide
NOx - collective term for nitrogen oxides (NO and NO2)
SO2 - sulfur dioxide
NOx
collective term for nitrogen oxides (includes NO and NO2)
SO2
sulfur dioxide
CO2
carbon dioxide
Secondary Pollutant
Pollutant formed from a reaction between primary Pollutant and other chemicals
Ex:
SO3
H2SO4
O3
SO3
Sulfur Trioxide
H2SO4
Sulphric acid
O3
Ozone
Thermal Inversion
the lack of mixing/convection due to density difference
(warm, lower density air already positioned on top)
Ozone
Stratospheric ozone is good. It helps block harmful UV and UVB from the sun. Tropospheric ozone is bad. It’s an irritant
Five main greenhouse gases
carbon dioxide, methane, nitrous oxide, and water vapor
Carbon Dioxide (CO2)
(Primary Outdoor Pollutants from Fossil Fuels)
colorless and odorless
GREENHOUSE GAS
Carbon Monoxide (CO)
(Primary Outdoor Pollutants from Fossil Fuels)
HIGHLY TOXIC, colorless and odorless
