A secondary air pollutant is a pollutant which results from two different contaminants in the environment. A classic example is the formation of photochemical smog when hydrocarbons and Nix mix in the presence of ultraviolet light. A similar effect results when, from two separate industrial processes, chlorine gas mixes with aromatic hydrocarbon vapours to make a lachrymator (tear gas)
Ozone and smog are both air pollutants. Ozone is a secondary pollutant formed when emissions from vehicles and industrial sources react with sunlight, while smog is a combination of pollutants, including ozone, formed from vehicle emissions and industrial processes.
Photochemical smog forms when pollutants such as nitrogen oxides and volatile organic compounds react in the presence of sunlight. This reaction produces ground-level ozone, which is a harmful air pollutant that can cause respiratory issues and other health problems.
No, "PAN" (peroxyacetyl nitrate) is not a primary pollutant; it is a type of secondary pollutant formed through chemical reactions of primary pollutants like volatile organic compounds (VOCs) and nitrogen oxides (NOx) in the atmosphere. PAN is a photochemical smog component formed in the presence of sunlight.
Ozone is a pollutant found in smog formed by the reaction of sunlight with pollutants like nitrogen oxides and volatile organic compounds. Smog is a mixture of pollutants, including ozone, particulate matter, and other harmful chemicals, that can have adverse effects on human health and the environment.
Ozone results from air and sunlight, and is increased greatly with the presence of oxides of nitrogen, among other chemicals.
Ozone layer present in troposphere is known as bad ozone. It is a pollutant and is a major constituent of urabn smog.
