What are the 5 primary pollutants?
5 Major Outdoor Air Pollutants
- Ozone (O3)
- Nitrogen Oxides (NOx)
- Carbon Monoxide (CO)
- Sulfur Dioxide (SO2)
- Particulate Matter (PM10 and PM2.5)
What is a secondary pollutant?
Examples of a secondary pollutant include ozone, which is formed when hydrocarbons (HC) and nitrogen oxides (NOx) combine in the presence of sunlight; NO2, which is formed as NO combines with oxygen in the air; and acid rain, which is formed when sulfur dioxide or nitrogen oxides react with water.
What are the major primary pollutants?
Primary air pollutants: Pollutants that are formed and emitted directly from particular sources. Examples are particulates, carbon monoxide, nitrogen oxide, and sulfur oxide.
What are the 5 primary air pollutants and their sources?
The five primary air pollutants include carbon monoxide, nitrogen oxides, particulate matter, sulfur oxides, and volatile organic compounds. The sources for all five of these pollutants include electricity production, industry, and transportation.
Is dust a primary or secondary pollutant?
Primary – Dust, smoke particles, nitrogen, carbon etc. Secondary – Formed when primary pollutants react or combine with one another, or the basic elements.
Which is an example of a primary pollutant?
Primary pollutants are types of pollutants that are directly harming the environment. These pollutants are usually harmful to human, plants and animals. Some examples of primary pollutants are carbon monoxide and nitrogen oxide. In this article, I will be sharing some examples of primary pollutants and where it comes from.
How are secondary pollutants made in the air?
Rather they are made in the air using other pollutants. Especially when primary pollutants react or interact with other molecules secondary pollutants are made. Therefore, by releasing primary pollutants to the air, not only it has direct effects, but it affects the atmosphere in an indirect way too. Ozone is one of the secondary pollutants.
How are fossil fuel burning primary and secondary pollutants?
Fossil fuel burning releases a mixture of primary pollutants. Primary pollutants can also be precursors for the secondary pollutants. There are some pollutants which can be both primary and secondary pollutants. That means while they are being emitted by a source directly, they are made from other pollutants too. What are Secondary Pollutants?
Which is an example of an air contaminant?
One of the major air contaminants is burning fossil fuels. This happens due to factory emissions and the use of automobiles. When one burns fossil fuels, smog gets formed as well as a thick layer containing particulate matter which encloses large zones in it.
