Solution(By Examveda Team)
O3 produces another air pollutant by reacting with oxides of nitrogen in presence of sunlight.High levels of nitrogen dioxide are also harmful to vegetation damaging foliage, decreasing growth or reducing crop yields. Nitrogen dioxide can fade and discolour furnishings and fabrics, reduce visibility, and react with surfaces.
In the sunlight, oxygen reacts with nitrogen oxides emitted mainly from vehicles, power plants, and industrial activities to form ozone, which in turn helps the formation of organic aerosol.
