Smog is a combination of the words smoke and fog and can be categorized into two different types: photochemical (summer) smog and acid (winter) smog. [1]
Photochemical smog mainly consists of ozone and is brownish in colour; nitrogen oxides and VOC’s, which originate from traffic and industries, causes this type of smog. [1]
Acid, or winter smog, is found in areas where vertical dispersion of air pollutants is not possible. [1]
