What are air pollutants?

Air Pollutants

  • Carbon Monoxide.
  • Lead.
  • Nitrogen Oxides.
  • Ozone.
  • Particulate Matter.
  • Sulfur Dioxide.
  • Other Air Pollutants.

What are air pollutants short answer?

Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.

What is meant by pollutant definition?

A pollutant is a substance that is present in concentrations that may harm organisms (humans, plants and animals) or exceed an environmental quality standard. The term is frequently used synonymously with contaminant.

What are air pollutants give examples?

The common air pollutants are:

  • Particulate matter (PM10 and PM2.
  • Ozone (O3)
  • Nitrogen dioxide (NO2)
  • Carbon monoxide (CO)
  • Sulphur dioxide (SO2)

What are two types of air pollutants?

Air Pollutants. There are two main types of air pollutants: primary and secondary.

What is pollutant and its types?

Different types of pollutants include: Nitrogen oxides (NOx) Sulfur oxides (SOx) Particulate matter (PM) Ground level ozone (O3)

How are air pollutants classified?

Types of Air Pollutants Air pollutants are classified as primary pollutants and secondary pollutants. (ii) Secondary air pollutants are formed because of reactions between primary pollutants and other elements in the atmosphere, such as the ozone.

Which is the main air pollutant?

The main gaseous pollutants are ozone, carbon monoxide, nitrogen dioxide, and sulfur dioxide. The main particulate matter (PM) pollutants are defined according to their aerodynamic diameter (those ≤10 μm referred to as PM10 and those ≤2.5 μm referred to as PM2.5).
