Quick Answer: Which Of The Following Is A Primary Pollutant?

Which one of the following is an example of primary pollutant?

Nitrogen oxides (NOx) Carbon monoxide (CO) Volatile organic compounds (VOCs) Sulfur oxides (SOx).

Is Pan a primary pollutant?

PANs are a secondary pollutant since they form in the atmosphere after the emission of primary pollutants. Sources of the pollutants required to create PANs include motor vehicles, tobacco smoke, and the burning of fossil fuels.

What does the abbreviation VOC stand for *?

abbreviation for volatile organic compound: one of a number of chemicals, including benzene and acetone, that evaporate or vaporize readily and are harmful to human health and the environment.

Which is the primary pollutant?

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 6 primary pollutants?

These six pollutants are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides.

What are examples of primary and secondary pollutants?

Primary pollutants include ammonia, sulfur dioxide, nitrogen dioxide and carbon monoxide. Secondary pollutants include ground-level ozone, acid rain and nutrient enrichment compounds.

Which is a secondary air pollutant quizlet?

Secondary air pollutant is. carbon monoxide, nitrogen oxides, sulfur dioxide, volatile organic compounds, particulate matter.

Is ozone a primary or secondary pollutant?

Ground-level ozone is a colorless and highly irritating gas that forms just above the earth’s surface. It is called a “secondary” pollutant because it is produced when two primary pollutants react in sunlight and stagnant air. These two primary pollutants are nitrogen oxides (NOx) and volatile organic compounds (VOCs).

Which of the following is a primary pollutant quizlet?

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.

What are 5 primary air pollutants?

5 Major Outdoor Air PollutantsOzone (O3)Nitrogen Oxides (NOx)Carbon Monoxide (CO)Sulfur Dioxide (SO2)Particulate Matter (PM10 and PM2.5)

What are the 5 primary air pollutants and their sources?

Name five primary air pollutants, and give sources for each. 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.

Which of the following is not a primary pollutants?

Which of these is NOT a primary pollutant? Explanation: Ozone is not a primary pollutant since it is formed by the photo-chemical reaction of oxygen with the UV rays and not directly discharged into the atmosphere by a source.

What are the sources of primary and secondary pollutants?

A primary source results from the direct emissions from an air pollution source. In contrast, a secondary source results from the formation of a pollutant in the atmosphere from the chemical reaction of precursors emitted from air pollution sources.

What is a secondary pollutant quizlet?

A secondary pollutant is when a primary pollutant comes into contact with other primary pollutants or with naturally occurring substances. An example is ground-level ozone.

Is oxygen a primary 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.
