What is primary pollutant in biology?

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 is a primary pollutant quizlet?

Primary Pollutant. a harmful substance, such as soot or carbon monoxide, that is emitted directly into the atmosphere. Major ones are nitrogen oxides, sulfur dioxide, particulate matter and hydrocarbons.

What pollutants are primary?

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 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 primary and secondary pollutants with example?

Examples of primary pollutants include sulfur dioxide (SO2), carbon monoxide (CO), nitrogen oxides (NOX), and particulate matter (PM). Examples of secondary pollutants include photochemical oxidants (ozone, nitrogen dioxide, sulfur trioxide) and secondary particulate matter.

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.

Which of the following is an example of a primary pollutant quizlet?

A primary pollutant is a pollutant that is put directly into the air by human activity. An example is soot from smoke.

What are examples of primary and secondary pollutants?

What is not a primary pollutant?

1. 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 5 main pollutants?

The common air pollutants are:

  • Particulate matter (PM10 and PM2.
  • Ozone (O3)
  • Nitrogen dioxide (NO2)
  • Carbon monoxide (CO)
  • Sulphur dioxide (SO2)

What is secondary pollution?

Secondary pollutants are pollutants which form in the atmosphere. These pollutants are not emitted directly from a source (like vehicles or power plants). Instead, they form as a result of the pollutants emitted from these sources reacting with molecules in the atmosphere to form a new pollutant.

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.
