Document Summary
They are as follows: carbon monoxide: colorless, odorless gas, produced primarily by the incomplete combustion of fuel. Sources: vehicles and engines account for 78% in us, 80% worldwide; other sources include industrial processes, combustion of waste, and residential wood burning. Catalytic converters now eliminate most of this from auto exhaust. Co has a relative short half life compared to carbon dioxide: sulfur dioxide: colorless gas with pungent odor. Most of the pollution results from the combustion of coal for electricity generation and industry, leading to industrial smog. Once in the atmosphere, can form sulfur trioxide, forming acid rain: nitrogen dioxide: foul-smelling, reddish, brown gas that contributes to photochemical smog and acid deposition. Sources: vehicle engines and power plants: tropospheric ozone: colorless gas is a secondary pollutant created the interaction of sunlight, heat, nitrogen oxides, and volatile organic compounds. Examples: fine dust, aerosols from coal, diesel engine exhaust.
