What are primary pollutants quizlet?
A primary pollutant is a pollutant that is put directly into the air by human activity. An example is soot from smoke. 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.
What are primary pollutants?
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 primary pollutants apes?
Primary pollutants are those that are emitted directly from a source. Primary sources include internal combustion vehicles, wildfires, factories, coal-burning power plants, agriculture, and volcanoes. Smog and acid precipitation are both examples of secondary pollutants.
How are primary pollutants compared to secondary pollutants quizlet?
How are primary pollutants compared to secondary pollutants? Primary pollutants are air pollutants that are emitted directly from a source, whereas secondary pollutants are formed when primary pollutants react chemically in the atmosphere.
Which of these pollutants is a secondary pollutant quizlet?
Secondary pollutants are formed when primary pollutants react with one another or with the basic components of air to form new harmful pollutants. List 3 each of primary and secondary pollutants. Primary: Sulfur dioxide, nitrogen oxide, lead. Secondary: ozone, NO2, and acid rain.
How many primary pollutant are there?
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 the types of pollutants?
Different types of pollutants include:
- Nitrogen oxides (NOx)
- Sulfur oxides (SOx)
- Particulate matter (PM)
- Ground level ozone (O3)
- Volatile organic compounds (VOCs)
- Mercury (Hg)
- Peroxyacyl nitrates (PANs)
- and more.
How do primary pollutants become part of the atmosphere?
Primary pollutants are released from the combustion of fossil fuels. Secondary air pollutants are formed when primary pollutants react with other compounds. • Ozone (O3) forms when primary pollutants such as NOX and VOCs react with oxygen in the presence of sunlight.
What is a primary air pollutant produced from burning coal?
Carbon dioxide (CO2), which is the primary greenhouse gas produced from burning fossil fuels (coal, oil, and natural gas)
