Secondary air pollutants
-
Only harmless chemicals
-
Only dangerous chemicals
Correct Answer
A. Secondary air pollutantsExplanation
Reactions that occur among substances in the atmosphere can produce secondary air pollutants. Unlike primary air pollutants, which are directly emitted into the air, secondary air pollutants are formed through chemical reactions involving primary pollutants and other atmospheric components. These reactions can occur through processes such as photochemical reactions or atmospheric oxidation. Secondary air pollutants can include ozone, sulfuric acid, and nitric acid, among others. These pollutants can have harmful effects on human health and the environment.Rate this question:
