What are the conventional air pollutants? Thank you!

There are many kinds of pollutants in the atmosphere, which can be divided into aerosol pollutants and gaseous pollutants according to their existing States.

Aerosol pollutants include dust, smoke, fly ash, smoke, fog, etc.

Gaseous pollutants include organic and inorganic substances. Organic compounds include hydrocarbons (hydrocarbons, aromatic hydrocarbons, polycyclic aromatic hydrocarbons, etc. ), oxygen-containing organic compounds (aldehydes, ketones, phenols, etc. ), nitrogenous organic compounds (aromatic amines, nitriles, etc.). ), sulfur-containing organic compounds (mercaptan, thiophene, etc. ) and chlorine-containing organic compounds (chlorinated hydrocarbons, chlorinated alcohols, organochlorine pesticides, etc. ). Inorganic substances include sulfides (sulfur dioxide, sulfur trioxide, hydrogen sulfide) and nitrogen-containing compounds (nitric oxide, nitrogen dioxide, ammonia gas, etc.). ), halides (chlorine, hydrogen chloride, hydrogen fluoride, etc. ) and carbon oxides (carbon monoxide, carbon dioxide, etc. ).
