Photochemical smog
The presence of VOCs in the atmosphere plays an im portant role in the formation of ground level ozone, photochemical oxidants, and smog episodes, and they are harmful to the ecosystem.
In the sunlight, VOCs react with nitrogen oxides emitted mainly from vehicles, power plants, and industrial activities to form ozone, which in turn helps the formation of organic aerosol.
