Primary Pollutants: These substances typically enter the air through industrial emissions or vehicle exhausts. They may also be released into the atmosphere when fuel is burned during coal mining operations or uncontrolled forest fires.

They include sulfur dioxide, nitrogen oxides, ozone (smog), fine particles, and lead. Secondary Pollutants: These substances are usually created when primary pollutants react with atmospheric components such as sunlight or water vapor, which produce a variety of toxic chemicals (such as formaldehyde) in the air.

They include nitrogen dioxide, sulfuric acid aerosols, particulate matter from coal-fired power plants and other industrial sources, ozone layer depletion. Secondary pollutants also come from burning fossil fuels for transportation needs like gasoline powered vehicles that emit greenhouse gases like carbon dioxide into the atmosphere.

Aerosol particles contribute to cloud formation through nucleation events which can affect global temperatures significantly. The Difference Between Primary and Secondary Pollutants: The difference between primary and secondary pollutants is based on whether they cause
