- Photochemical smog is nothing but the haze in the atmosphere that is accompanied by high levels of ozone and also gases in the atmosphere like nitrogen oxides present in air that are caused by the action of sunlight.
- The energy of sunlight converts the pollutants formed by combustion of fossil fuels that releases several pollutants and also other volatile organic compounds into the most toxic chemicals that is called photochemical smog.
Thus, the gases or pollutants present in air is responsible for the photochemical smog
