No, formaldehyde is not considered a primary pollutant. It is a secondary pollutant that forms in the atmosphere as a result of chemical reactions involving primary pollutants such as volatile organic compounds (VOCs) and nitrogen oxides.
No. Hydrocarbon is a Primary pollutant.
secondary pollutant because of the it extracts a gas / smoke that contributed to global warming .
secondary pollutant. deals with oxygen in air
Primary pollutants are pollutants that enters the air directly from a source and Secondary pollutants are air pollutantsproduced by the reaction of a primary pollutant with some other pollutant
Ground ozone is considered a secondary pollutant because it is not directly emitted into the atmosphere, but forms through chemical reactions involving primary pollutants like nitrogen oxides and volatile organic compounds in the presence of sunlight.
No, carbon monoxide (CO) is not considered a primary pollutant. It is a secondary pollutant that forms from the incomplete combustion of fossil fuels and is primarily produced by vehicles and industrial processes.
Ozone is not a primary pollutant. It is formed in the atmosphere as a secondary pollutant through reactions involving primary pollutants like nitrogen oxides and volatile organic compounds in the presence of sunlight.
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.
Yes, ozone is considered a secondary pollutant because it is formed through chemical reactions between primary pollutants, such as nitrogen oxides and volatile organic compounds, in the presence of sunlight.
Ozone is called a secondary pollutant because it is not directly emitted into the atmosphere. Instead, it is formed from chemical reactions between primary pollutants such as nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the presence of sunlight. These reactions produce ozone as a secondary byproduct, which can be harmful to human health and the environment.
Nitrogen oxide is considered a primary pollutant because it is directly emitted into the atmosphere from sources such as vehicle exhaust and industrial activities.
