Secondary pollutants are not directly emitted but are formed when primary pollutants react in the atmosphere. Tropospheric ozone is a major component of photochemical smog. It is formed through complex photochemical reactions involving primary pollutants such as nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the presence of sunlight (specifically UV radiation).
Which secondary pollutant is produced by UV rays of sun lights?
