Primary pollutants include carbon monoxide, oxides of nitrogen, sulfur oxides, volatile organic compounds (VOCs) and particulate pollution such as dust, ash or salt particles.
Which of the following are examples of primary pollutants?
Primary pollutants include oxides of nitrogen and sulphur, carbon monoxide, particulate matter, hydrocarbon, mercury and many more . Carbon dioxide is not considered as a pollutant because it does not harm our health but it is a proven greenhouse gas.
Which of the following is primary pollutant?
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 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.
Which of the following are primary air pollutants?
- carbon monoxide (CO) odorless, colorless, poisonous gas. ...
- oxides of nitrogen (NO x , NO) NO – nitric oxide. ...
- sulfur oxides (SO x ) SO 2 – sulfur dioxide. ...
- volatile organic compounds (VOCs) highly reactive organic compounds. ...
- particulate matter (dust, ash, salt particles) bad for your lungs.
What are primary and secondary pollutants give 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.
Is a pollutant a primary?
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 co2 a secondary pollutant?
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 (CO 2 ), a greenhouse gas, come from carbon monoxide.
What are pollutants examples?
These are those which are emitted directly from the source and persist in the form in which they were added to the environment. Typical examples of pollutants included under this category are ash, smoke, fumes, dust, nitric oxide, sulphur dioxide, hydrocarbons etc .
What are the 5 primary air pollutants and their sources?
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 are the 5 main pollutants?
- Ozone (O3)
- Nitrogen Oxides (NOx)
- Carbon Monoxide (CO)
- Sulfur Dioxide (SO2)
- Particulate Matter (PM10 and PM2.5)
What are the main 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.
Is dust a primary or secondary pollutant?
Smoke , soot, dust, and liquid droplets released into the air either by the burning of fuel or other industrial or agricultural processes, are considered primary pollutants .
Is smog a primary pollutant?
Smog in New York CityPhotochemical smog is composed of primary and secondary pollutants . Primary pollutants include nitrogen oxides and volatile organic compounds as a result of industrial processes, while secondary pollutants are created through the reaction of primary pollutants with ultraviolet light.
Is DDT a primary pollutant?
Smog, photochemical smog, ozone and PAN all are secondary air pollutants. DDT is a primary soil pollutant .
What is difference between primary and secondary pollutants?
Primary pollutants are pollutants that are emitted from a source, directly into the atmosphere. Secondary pollutants are pollutants formed either due to a reaction between primary pollutants themselves or between a primary pollutant and any other atmospheric particle.
