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

A secondary pollutant is formed when primary pollutants undergo chemical reactions in the atmosphere. Examples include ozone, formed from the reaction of nitrogen oxides and volatile organic compounds, and sulfuric acid, formed from the reaction of sulfur dioxide and other compounds in the atmosphere.

Ozone is a pollutant. It is a secondary one. High ozone is good.


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.


What ozone layer is a secondary pollutant?

The ozone layer itself is not a pollutant; it is a protective layer in the Earth's stratosphere that shields us from harmful UV radiation. However, ground-level ozone, formed by the reaction of sunlight with pollutants like nitrogen oxides and volatile organic compounds, is a secondary pollutant that can be harmful to human health and the environment.
