Quick Answer: What Are The Sources Of Primary And Secondary Pollutants?

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..

What is a secondary air pollutant?

Secondary pollutants are pollutants which form in the atmosphere. These pollutants are not emitted directly from a source (like vehicles or power plants). … Photochemical smog is made up of various secondary pollutants like ozone, peroxyacyl nitrates (PANs), and nitric acid (seen in Figure 2).

What are examples of pollutants?

Types of pollutantsParticulate Matter. Particulate matter (PM) are inhalable and respirable particles composed of sulphate, nitrates, ammonia, sodium chloride, black carbon, mineral dust and water. … Black Carbon. … Ground-level Ozone. … Nitrogen dioxide. … Sulfur dioxide. … Carbon monoxide.

How are primary and secondary pollutants harmful for humans and environment?

Primary pollutants are directly generated from human activities like from car, from ships, from construction work etc. … Secondary pollutants form due to mixing of primary pollutants and natural resources such as water, air etc. They are harmful like mixing of sulphuric acid susoended in air with rain to form acid rain .

What are five kinds of pollutants?

The five major types of pollution include: air pollution, water pollution, soil pollution, light pollution, and noise pollution.

What are pollutants and their sources?

What are the primary and secondary pollutants?

Glossary: Primary & Secondary 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 primary and secondary air pollutants with examples?

Primary air pollutants: Pollutants that are formed and emitted directly from particular sources. Examples are particulates, carbon monoxide, nitrogen oxide, and sulfur oxide. Secondary air pollutants: Pollutants that are formed in the lower atmosphere by chemical reactions.

What are three sources of pollutants?

Types of Sources stationary sources – such as power plants, oil refineries, industrial facilities, and factories. area sources – such as agricultural areas, cities, and wood burning fireplaces. natural sources – such as wind-blown dust, wildfires, and volcanoes.

Which of the following is primary air 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), SO2, volatile organic compounds (VOCs) and particulate matter (dust, ash, salt particles).

What are the major air pollutants and their sources?

Air Pollution SourcesParticulate Matter (PM10 and PM2.5) Particulate matter (PM) is a complex pollutant as it contains a variety of components in variable concentrations. … Nitrogen Dioxide (NO2) … Ozone (O3) … Sulphur Dioxide (SO2) … Volatile Organic Compounds (VOCs) … Carbon Monoxide (CO) … Lead (Pb) … Toxic Organic Micro-Pollutants (TOMPs)More items…

What are the sources of primary pollutants?

Primary pollutants can be emitted from many sources including cars, coal-fired power plants, natural gas power plants, biomass burning, natural forest fires, volcanoes, and many more. The effects of primary pollutants are of concern as they can be harmful to humans, animals and plants.

What are the 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 2 types of pollutants?

The two types of air pollutants are primary pollutants, which enter the atmosphere directly, and secondary pollutants, which form from a chemical reaction.

Is Pan a secondary pollutant?

PANs are secondary pollutants, which means they are not directly emitted as exhaust from power plants or internal combustion engines, but they are formed from other pollutants by chemical reactions in the atmosphere.

What are the five pollutants?

The common air pollutants are:Particulate matter (PM10 and PM2. … Ozone (O3)Nitrogen dioxide (NO2)Carbon monoxide (CO)Sulphur dioxide (SO2)

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.
