A primary pollutant is an air pollutant emitted directly from a source.
A secondary pollutant is not directly emitted as such, but forms when other pollutants (primary pollutants) react in the atmosphere.
these are harmful due to the fact that both are making the environment polluted and thus causing different disease like lung cancer, cholera, jaundice etc
