Differbetween
Primary pollutants are emitted from natural or anthropogenic sources directly into the atmosphere, while secondary pollutants result from the chemical reactions or the physical interactions between the primary pollutants themselves or between the primary pollutants and other atmospheric components.

What is the difference between primary and secondary air pollutants What are some examples of each?
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 examples of primary and secondary pollutants?
Secondary pollutant form when primary pollutants emitted directly from a combustion process react in the atmosphere. Primary pollutants include ammonia, sulfur dioxide, nitrogen dioxide and carbon monoxide. Secondary pollutants include ground-level ozone, acid rain and nutrient enrichment compounds.
What is the difference between primary and secondary pollutants quizlet?
What is the difference between primary and secondary pollutants? Primary pollutants are harmful substances emitted directly into the air. Secondary pollutants are formed when primary pollutants react with one another or with the basic components of air to form new harmful pollutants.
What are the primary and secondary air pollutants?
The major primary pollutants are Oxides of Sulphur, Oxides of Nitrogen, Oxides of Carbon, Particulate Matter, Methane, Ammonia, Chlorofluorocarbons, Toxic metals etc. ... The secondary pollutants are not emitted directly.
What are secondary pollutants examples?
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 5 primary air pollutants?
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's the difference between primary and secondary?
Primary sources are first-hand accounts of a topic while secondary sources are any account of something that is not a primary source. ... Published research, newspaper articles, and other media are typical secondary sources.
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 Pan a secondary pollutant?
Peroxyacetyl nitrate (PAN) and ozone are the two important secondary photochemical air pollutants found in the urban at- mosphere (1-3). Of the two, PAN is the more useful indicator of photochemical reactions in polluted air as, unlike ozone, it appears to have no large natural source (2-7).
Is smog a secondary or primary pollutant?
Smog in New York CityPhotochemical smog is composed of primary and secondary pollutants. Primary pollutants include nitrogen oxides and volatile organic compounds as a result of industrial processes, while secondary pollutants are created through the reaction of primary pollutants with ultraviolet light.
What is the secondary pollutant?
Secondary pollutants are pollutants which form in the atmosphere. These pollutants are not emitted directly from a source (like vehicles or power plants). ... Photochemical smog is made up of various secondary pollutants like ozone, peroxyacyl nitrates (PANs), and nitric acid (seen in Figure 2).
What is the difference between primary and secondary sources of particulate matter?
Primary particles are directly released into the atmosphere by wind, combustion processes, or human activities. ... Secondary particles are those that form in the atmosphere from other gaseous pollutants, particularly sulfur dioxide, nitrogen oxides, ammonia, and volatile organic compounds.
