What are secondary pollutants?
Definition: A primary pollutant is an air pollutant emitted directly from a source.
A secondary pollutant is not directly emitted as such, but forms when other pollutants (primary pollutants) react in the atmosphere..
What are the primary pollutants?
Primary pollutants are any type of pollutant directly into the environment….Types of primary pollutants include:Nitrogen oxides (NOx)Carbon monoxide (CO)Volatile organic compounds (VOCs)Sulfur oxides (SOx)Particulate matter (PM)Mercury.and more.
What are natural pollutants?
A natural pollutant is a pollutant created by substances of natural origin such as volcanic dust, sea salt particles, photochemically formed ozone, and products of forest fibres, among others.
What are 4 major pollutants?

What natural activity causes pollution?
Volcanic Activity: Volcanic eruptions are a major source of natural air pollution. When an eruption occurs, it produces tremendous amounts of sulfuric, chlorine, and ash products, which are released into the atmosphere and can be picked up by winds to be dispersed over large areas.
What are primary and secondary air pollutants with examples?
Primary air pollutants: Pollutants that are formed and emitted directly from particular sources. Examples are particulates, carbon monoxide, nitrogen oxide, and sulfur oxide. Secondary air pollutants: Pollutants that are formed in the lower atmosphere by chemical reactions.
What are the 2 types of pollutants?
The two types of air pollutants are primary pollutants, which enter the atmosphere directly, and secondary pollutants, which form from a chemical reaction.
