Pollutants can hang around: depending on the chemical, air pollutants can linger in the atmosphere for days to 100s of years, the exact amount of time they linger is called their residence time. What are some of the key pollutants: epa and state/local agencies monitor six major air pollutants, carbon monoxide (co): colorless, odorless gas produced by vehicle engines, sulfur dioxide (so2): colorless, smelly gas produced by coal combustion. Converts to sulfuric acid in the atmosphere and returns to the earth as acid rain: nitrogen oxides (nox): class of nox compounds produced from vehicles and energy generation. Produce acid rain, deplete ozone, and form smog: volatile organic compounds (vocs): huge group of carbon containing compounds (organic=carbon in chemistry).
