उत्तर

PAN is photochemical oxidant.

Explanation:

PAN is a secondary pollutant formed in photochemical smog. It is produced by the reaction of nitrogen oxides and hydrocarbons in the presence of sunlight and acts as a strong oxidant which can damage plants by shutting down photosynthesis and aging them prematurely. It is not a primary air pollutant but a photochemical oxidant formed in the atmosphere due to sunlight-driven reactions
