What are examples of primary and secondary pollutants?

What are examples of primary and secondary pollutants?

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 are secondary pollutants?

Secondary pollutants are pollutants which form in the atmosphere. These pollutants are not emitted directly from a source (like vehicles or power plants). Different types of secondary pollutants include: Ozone (O3) Sulfuric acid and nitric acid (component of acid rain)

What are examples of secondary pollutants quizlet?

Smog is formed by chemical reactions that involve sunlight, air, automobile exhaust, and ozone. Smog is an example of a secondary pollutant.

Which of the following pollutant is secondary pollutant?

Secondary pollutants are not emitted directly. They are formed from the combination of primary pollutants with some other compound. Examples of secondary pollutants are Ozone, Formaldehyde, PAN (peroxy acetyl nitrate) and Smog etc.

Is co2 secondary pollutant?

Carbon Monoxide (CO) Most of the carbon monoxide pollution comes from burning fossil fuels in vehicles, factories, and power plants, but another major source is from burning wood or crop waste. Secondary pollutants like ozone and carbon dioxide (CO2), a greenhouse gas, come from carbon monoxide.

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 DDT a secondary pollutant?

Smog, photochemical smog, ozone and PAN all are secondary air pollutants. DDT is a primary soil pollutant.

Is co2 a secondary pollutant?

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.

Is NO2 primary or secondary pollutant?

While NO2 is a primary pollutant, it is also a contributing component for secondary pollutants formed from a chemical reaction.

What are the differences between primary and secondary pollutants?

Primary pollutants are produced directly from a source but secondary pollutants are produced by reactions between primary pollutants and other chemicals.

Which is the second form of air pollution?

Ans- The second form of air pollution is particulate matter such as smoke, dust, fly ash and mists. The pollutants is further classified as primary pollutants and secondary pollutants. … The production of PAN during photochemical reactions is an example of secondary pollutants. 2) Which are more harmful primary or secondary pollutants?

Which is an example of a secondary problem?

Primary issues lead to secondary problems, such as how primary pollutants lead to secondary pollutants. Explore what secondary pollutants are, along with different examples of secondary air pollutants like nitrogen dioxides and smog. When it comes to pollutants, there are two different types: primary and secondary pollutants.

How is acid rain a secondary pollutant?

Acid rain, a secondary pollutant, occurs anywhere near fossil fuel-burning power plants. This rain, filled with nitrogen and sulphur oxides, flows into waterways, changing marine habitats. Additionally, it may have a negative impact on agriculture harvest yield.
