Organic pollutants are persistent organic pollutants(POPs). Examples are DDT and lindane, industrial chemicals such as polychlorinated biphenyls (PCBs), and substances such as dioxins, all of which accumulate and are slow to degrade, and may have adverse impacts on human health and the environment.

Why is ozone called a secondary pollutant?
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.
A harmful material that can enter the biosphere through land air or water is called?
Pollutant
Is ozone considered to be a serious pollutant?
Yes, it is. But only ground ozone is pollutant.
What is the importance of the role of ozone in air pollution?
Ozone is a pollutant. It is at ground level a pollutant.
What ozone layer is a secondary pollutant?
The ozone at ground is a secondary pollutant. It is also called bad ozone.
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 'P A N' a secondary pollutant?
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.
Define biodegradable pollutant and non-biodegradable pollutant and give examples of each?
Biodegradable pollutant specifically refer to pollutants that are not harmful and are able to compose naturally. e.g. sewage Non biodegradable pollutant refer to organic compound such as metal which have a high toxic content and have a very harmful effect upon environment. This organic compound cannot decompose by microorganism

What is a non persistent pollutant?
the opposite of a persistant pollutant.
Is formaldehyde a primary pollutant?
Yes, it is a primary pollutant
Ozone is a pollutant?
Yes, in the troposphere, ozone is a pollutant.
Is hydrocarbon a secondary pollutant?
No. Hydrocarbon is a Primary pollutant.
How does pollutant harmful to the ecosystem?
how dose the pollutant hamrful to the ecosystem
Is ground ozone a primary or secondary pollutant?
Secondary Pollutant
A harmful material that can enter the biosphere through land air or water is called?
Pollutant
What does Organic pollutant mean?
Persistent Organic Pollutants are chemicals that are insoluble in water, don't biodegrade, and tend to persist in the environment. Pops may be residual residue of other chemicals, used in factory's or as pesticides. The 12 most "notorious" have been banned by the UN.
