What is a primary pollutant?

• A pollutant formed by chemical reactions in the atmosphere

• A pollutant that is put directly into the atmosphere by human or natural activity

What is the main difference between primary and secondary pollutants?

• Primary pollutants are more harmful than secondary pollutants

• Primary pollutants are directly emitted, while secondary pollutants form in the atmosphere

• Secondary pollutants are directly emitted, while primary pollutants form in the atmosphere

• There is no difference between them
