Which of the following is an example of a secondary 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.

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.

One may also ask, 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.

Secondly, what is an example of 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.

What do you mean by secondary pollutant?

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)

Is co2 a secondary pollutant?

Secondary pollutant form when primary pollutants emitted directly from a combustion process react in the atmosphere. Primary pollutants include ammonia, sulfur dioxide, nitrogen dioxide and carbon monoxide. Secondary pollutants include ground-level ozone, acid rain and nutrient enrichment compounds.

What is primary and secondary air pollutant?

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.

Is DDT a secondary pollutant?

It includes the DDT. The secondary pollutants are those which are not able to maintain their form in the environment. It includes the peroxyacyl nitrate which is formed due to the reaction between the primary pollutants like the hydrocarbons and nitrogen oxides. It includes the DDT, fungicides etc.

Is so2 a secondary pollutant?

Sulfur dioxide (SO2) Like nitrogen dioxide, sulfur dioxide can create secondary pollutants once released into the air. Secondary pollutants formed with sulfur dioxide include sulfate aerosols, particulate matter, and acid rain.

Is no2 a primary pollutant?

The amount of nitrogen oxides emitted into the atmosphere as air pollution, from both man-made sources, can be quite significant. It’s mainly produced by road traffic and energy production. While NO2 is a primary pollutant, it is also a contributing component for secondary pollutants formed from a chemical reaction.

Which of the following is a primary pollutant?

A primary pollutant is an air pollutant emitted directly from a source e.g., carbon monoxide (CO), oxides of nitrogen (NOx, NO), sulfur oxides (SOx), SO$$_2$$, volatile organic compounds (VOCs) and particulate matter (dust, ash, salt particles).

What is photochemical smoke?

Photochemical smog. Photochemical smog is a type of smog produced when ultraviolet light from the sun reacts with nitrogen oxides in the atmosphere. It is visible as a brown haze, and is most prominent during the morning and afternoon, especially in densely populated, warm cities.

Is Pan a secondary pollutant?

Structure of a PAN called peroyacetyl nitrate. Peroxyacyl nitrates or PANs are a component of photochemical smog, produced in the atmosphere when oxidized volatile organic compounds combine with nitrogen oxide. They are a secondary pollutant since they form in the atmosphere after the emission of primary pollutants.

What is a pollutant quizlet?

Pollution. any matter or energy released into the environment that causes undesirable impacts on the healthy and well being of humans or other organisms, Can come in many forms like Physical, Chemical, Biological, Affects air, water, soil, human health.

Why is ozone classified as a secondary air 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).

How do primary and secondary pollutants form quizlet?

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.

Why is soot from smoke an example of a primary pollutant?

An example of a primary pollutant is soot from smoke. Are formed when primary pollutants react with other primary pollutants or with naturally occurring substances such as water vapor. Smog, results from chemical reactions that involve sunlight, air, auto exhaust, and ozone.

Which of the following is one of the chief sources of smog?

Contact POLLUTANT EXAMPLES OF SOURCES Ozone (O3) Precursor sources1: motor vehicles, industrial emissions, and consumer products Carbon Monoxide (CO) Any source that burns fuel such as cars, trucks, construction and farming equipment, and residential heaters and stoves Nitrogen Dioxide (NO2) See carbon monoxide sources

Which of the following contributes most to acid precipitation?

Sulfur dioxide (SO2) and nitrogen oxides (NOx) released into the air by fossil-fuel power plants, vehicles and oil refineries are the biggest cause of acid rain today, according to the EPA. Two thirds of sulfur dioxide and one fourth of nitrogen oxide found in the atmosphere come from electric power generators.
