Primary Air Pollutants:__________________________________________________________
Primary Pollutant
1 Carbon Oxides (CO and CO2)
2 Nitrogen Oxides (NOx)
NO – colorless/odorless
NO2 – reddish brown/pungent
3 Sulfur Dioxide (SO2)
(“fireworks smell”)
4 Particulate Matter (PM)
(dust, soot, ash, salts)
5 Volatile Organic Compounds (VOCs)
hydrocarbons: methane, propane, benzene
chlorofluorocarbons (CFCs)
formaldehyde
6 Heavy Metals
(Mercury, Lead)
Source
both are asphyxiants – prevents O2
delivery to blood, tissue, and organs
CO2 – greenhouse gas

Health / Environmental Effects
smelting
toxic to plants
respiratory irritation / illnesses
component of acid rain
contributes to smog
natural and
anthropogenic
respiratory problems
(asthma, bronchitis)
cardiovascular / lung diseases
may lead to cancer
volcanic ash  climate alteration
gas fumes, glues,
solvents, paints
toxic (affects many body systems)
may be carcinogenic
contributes to smog
contributes to ground level ozone
smelting
coal burning
gasoline (phasedown in 1980s)
brain damage and sensory impairment
kidney damage
harmful to developing fetuses and
young children
