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)
What else can I help you with?
Is Nitrogen oxide a primary or secondary pollutant?
secondary pollutant. deals with oxygen in air
Is n2 considered an air pollutant?
No, n2 (nitrogen gas) is not considered an air pollutant.
Is nitrogen dioxide considered an air pollutant?
Yes, nitrogen dioxide is considered an air pollutant.
Which of the following air pollutants is not a primary pollutant?
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.
What substance is not considered to be an air pollutant?
A lot of substances are not air pollutant. You must specify which kind of substance do you refer as a probable air pollutant.

What the difference between primary and secondary pollutants?
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
What is the most common air pollutant in the US?
Ozone is considered to be the most common air pollutant in the United States.
Is pollen a primary or secondary pollutant?
Pollen is considered a primary pollutant because it is a natural substance released directly into the air by plants during their reproductive processes. Unlike secondary pollutants, which are formed through chemical reactions in the atmosphere, pollen is emitted as is. It can contribute to air quality issues, particularly for individuals with allergies or respiratory conditions.
How is ozone a secondary air pollutant?
A secondary pollutant is one that is not directly emitted by a point source. Ozone is not directly emitted - it requires the sun to form. It forms as a result of direct pollutants such as NO2 and volatile organic compounds.
Is carbon monoxide secondary or primary?
Carbon monoxide is considered a primary air pollutant because it is directly emitted into the atmosphere by sources like vehicles and industrial processes. It can then undergo chemical reactions to form secondary pollutants such as ground-level ozone.
What form of ozone is considered a secondary pollutant?
secondary pollutants are pollutants that form from chemical reactions that occur when primary pollutants come in contact with other primary polluants or with naturally occurring substances such as water vapor.
How can a substance that is ordinarily not considered a pollutant become a pollutant?
This happens when unharmful materials mixed to a toxic or a harmful subatance. When this happens it will considered a pollutant
