5. AIR POLLUTANTS There are many substances in the air which effects the health of living organisms are called Air Pollutants

6. TYPES OF AIR POLLUTANTS Primary air pollutants Primary air pollutants Secondary air pollutants Secondary air pollutants

7. PRIMARY AIR POLLUTANTS These are the substances which are directly emitted from a process. These are the substances which are directly emitted from a process. For example – CO from motor vehicles, ash from volcanic eruptions. For example – CO from motor vehicles, ash from volcanic eruptions.

8. SECONDARY AIR POLLUTANTS These are the substances which are not emitted directly rather they form in the air when primary pollutants reacts. These are the substances which are not emitted directly rather they form in the air when primary pollutants reacts. For example – Ground level ozone that makes up Photochemical Smog. For example – Ground level ozone that makes up Photochemical Smog.
