A secondary pollutant is not directly emitted, it is formed in the atmosphere when primary pollutants are mixed as through chemical and photochemical reaction. For example, a secondary pollution would be ozone which is formed when hydrocarbons and nitrogen oxides combine in sunlight
primary pollutant ex. vehicle exhaust,volcanic ash,industrial emissions
secondary pollutants ex. smog,ozone
There are a number of environmental pollution sources. A few are crude oil, carbon monoxide, carbon dioxide, ammonia, phosphorous, and sulfur.
primary pollutant ex.vehicle exhaust volcanic ash industrial emissions
Secondary Pollutants-ex Ozone,Smog. Ozone is produced when sunlight reacts with vehicle exhaust and air.
they are formed by primary pollutants
Secondary Pollutant
secondary pollutant. deals with oxygen in air
Asbestos does not form secondary pollutants. It is a chemically inert fiber.
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.
A primary pollutant is emitted directly into the atmosphere, so exhaust, smoke and fumes are all primary pollutants. Acid rain is a secondary pollutant.

No. Hydrocarbon is a Primary pollutant.
The ozone at ground is a secondary pollutant. It is also called bad ozone.
Volcanic gases and ash are two examples of secondary pollutant
The ozone at ground level is a pollutant. It acts as a secondary pollutant.
secondary pollutant because of the it extracts a gas / smoke that contributed to global warming .
yes it is
Ozone is a pollutant. It is a secondary one. High ozone is good.
Asbestos does not form secondary pollutants. It is a chemically inert fiber.
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.
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
