Air pollutants responsible for photochemical smog
The main pollutants that contribute to photochemical smog are nitrogen oxides (NOx) and volatile organic compounds (VOCs). These pollutants react in the presence of sunlight to form ozone and other harmful chemicals.
Air pollutants carbon monoxide
Carbon monoxide is a colorless, odorless gas that is produced whenever any fossil fuel is burned. It is a pollutant that can have serious health effects, particularly when it builds up indoors.
