What is the difference between primary and secondary air 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 is the difference between primary and secondary 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.
What is the difference between primary and secondary air?
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.
How does a primary pollutant differ from a secondary pollutant give an example of each?
A primary pollutant is emitted directly into the atmosphere and a secondary pollutant is produced from reactions within atmospheric substances. An example of a primary pollutant is carbon monoxide. An example of a secondary pollutant would be Tropospheric ozone.
What is a secondary air pollutant?
Secondary air pollution is pollution caused by reactions in air already polluted by primary emissions (from factories, automobiles and so forth). An example of secondary air pollution is photochemical smog.
What is primary air?
Definition of primary air : air admitted to the fuel stream or area ahead of the combustion zone in a burner or furnace.
What is a secondary air pollutant quizlet?
Secondary air pollutant is. carbon monoxide, nitrogen oxides, sulfur dioxide, volatile organic compounds, particulate matter.
What are primary and secondary pollutants give example?
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 and primary 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.
Which is a secondary air pollutant?
Examples of a secondary pollutant include ozone, which is formed when hydrocarbons (HC) and nitrogen oxides combine in the presence of sunlight. Nitrogen oxide 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 is secondary air quizlet?
pollutants that are produced by humans and nature. secondary air pollutant. air pollutants formed when primary air pollutants react with one another or with other chemicals in the air. particulate matter.
What are primary and secondary air pollutants Wikipedia?
Pollutants are classified as primary or secondary. Primary pollutants are usually produced by processes such as ash from a volcanic eruption. Other examples include carbon monoxide gas from motor vehicle exhausts or sulfur dioxide released from factories. Secondary pollutants are not emitted directly.
What are the primary air pollutants?
Major air pollutants include carbon monoxide (CO), ammonia (NH3), nitric oxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter (PM), sulphur dioxide (SO2) and volatile organic compounds (VOC).
What is the main reason we need to distinguish between primary and secondary pollutants?
Identifying air pollutants and studying the difference between primary and secondary pollutants are important for the control and prevention of atmospheric pollution, especially through the reduction of anthropogenic sources.
What is secondary air pollutant?
Secondary air pollution is pollution caused by reactions in air already polluted by primary emissions (from factories, automobiles and so forth). An example of secondary air pollution is photochemical smog.
Which is secondary pollutant?
Secondary pollutants are defined as the pollutants which form in the atmosphere. These secondary pollutants do not come directly from a source (like vehicles or power plants). It forms as a result of the pollutants the sources emit and reacting with the molecules in the atmosphere.
What are the primary pollutants of air pollution?
Primary pollutant
- Nitrogen oxides (NOx)
- Carbon monoxide (CO)
- Volatile organic compounds (VOCs)
- Sulfur oxides (SOx)
- Particulate matter (PM)
- Mercury.
- and more.
