ozone and sulfur oxides
Ozone is known to be a gaseous secondary pollutant which is formed by the interaction of VOCs and NO2 in the presence of sunlight. Thus, high ozone levels harm the plants which include trees and crop plants which accelerate the deterioration of fabric and rubber.
Sulfur oxide is a primary precursor for acidic precipitation and it is produced during the burning of fuels. This compound can harm plants, trees, human and animal lungs.
