Primary air pollutants are

• pollutants put directly into the air by human activity

• anything that enters the atmosphere from any organism

• would include photosynthesis and respiration

• occur from changes in other pollutants

Secondary Pollutants are

• related to clean air

• formed directly from industry

• part of water pollution

• formed when primary pollutants react with each other or other substances.
