Detailed explanation-1: -It is a precursor of CO2 and ozone. Sulfur dioxide (SO2), which reaches the atmosphere mainly as a consequence of human activities such as the burning of coal or oil.

Detailed explanation-2: -Sulfur dioxide is a gaseous pollutant that is emitted primarily by industrial furnaces or power plants burning coal or oil containing sulfur.

Detailed explanation-3: -Primary air pollutants: Pollutants that are formed and emitted directly from particular sources. Examples are particulates, carbon monoxide, nitrogen oxide, and sulfur oxide.

Detailed explanation-4: -CO is a colorless, odorless gas formed by the incomplete reaction of air with fuel. CO pollution occurs primarily from emissions produced by fossil fuel–powered engines, including motor vehicles and non-road engines and vehicles (such as construction equipment and boats).

Detailed explanation-5: -A primary pollutant is an air pollutant emitted directly from a source e.g., carbon monoxide (CO), oxides of nitrogen (NOx, NO), sulfur oxides (SOx), SO2, volatile organic compounds (VOCs) and particulate matter (dust, ash, salt particles).
