  • nitrogen dioxide.
  • ozone.
  • sulphur dioxide.

What are the 5 types of air 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 types of pollutants?

EPA has established national ambient air quality standards (NAAQS) for six of the most common air pollutants— carbon monoxide, lead, ground-level ozone, particulate matter, nitrogen dioxide, and sulfur dioxide—known as “criteria” air pollutants (or simply “criteria pollutants”).

How many types of pollutants are there?

When you think of environmental pollution, it typically comes in seven different types. These include air, water, land, radioactive, thermal, light, and sound pollution. Explore the definition and causes of each type of pollution.

What are pollutants classify them with examples?

ADVERTISEMENTS: (a) Primary Pollutants: 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 2 types of air pollutants?

There are two basic types of pollutants in the air. They are known as primary pollutants and secondary pollutants. Primary pollutants enter the air directly. Some are released by natural processes, like ash from volcanoes.

What is pollutants and its types?

The term “pollution” refers to any substance that negatively impacts the environment or organisms that live within the affected environment. The five major types of pollution include: air pollution, water pollution, soil pollution, light pollution, and noise pollution.

What are pollutants and types of pollutants?

Different types of pollutants include:

  • Nitrogen oxides (NOx)
  • Sulfur oxides (SOx)
  • Particulate matter (PM)
  • Ground level ozone (O3)
  • Volatile organic compounds (VOCs)
  • Mercury (Hg)
  • Peroxyacyl nitrates (PANs)
  • and more.

What are the two 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.

What are pollutants and classify its type in detail?

These are those substances which do not normally occur in nature but are added by man, for example, insecticides. (ii) Depending upon the form in which they persist after being released into the environment, the pollutants are categorized into two types, namely primary and secondary pollutants.

What are pollutants and different types of pollutants?

What are three types of air pollution?

Air quality regulators generally view air pollutants in three categories: criteria pollutants, air toxics, and greenhouse gases.

What are the two types of air pollutants?

Air Pollutants

  • Primary air pollutants: Pollutants that are formed and emitted directly from particular sources.
  • Secondary air pollutants: Pollutants that are formed in the lower atmosphere by chemical reactions.

What are pollutants and their types?


Pollutant Recipient
(a) pesticide lake, humans
(b) leachate soil, groundwater, humans
(c) liquid effluent (organic matter and tannery chemicals) river, humans, wildlife
(d) black smoke humans

What are the three major air pollutants?

Common Air Pollutants They are particulate matter (often referred to as particle pollution), ground-level ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. These pollutants can harm human health, harm the environment, and cause property damage.

What are the 2 main types of pollutants?

There are two basic types of pollutants in the air. They are known as primary pollutants and secondary pollutants.

What are the top 10 air pollutants?

Sources and Effects of 10 Common Air Pollutants

  1. Carbon Monoxide (CO) Carbon Monoxide is a highly toxic and dangerous pollutant, infamous for its lack of identifying color and smell.
  2. Lead (Pb)
  3. Ozone (O3)
  4. Nitrogen Dioxide (NO2)
  5. Sulfur Dioxide (SO2)
  6. Particulate Matter (PM)
  7. Carbon Dioxide.
  8. Methane.

What are 3 types of pollutants?

The three major types of pollution are air pollution, water pollution, and land pollution.

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).

What are primary and secondary air pollutants?

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 three different categories of air pollutants?

What are the types of air pollution PDF?

There are six primary air pollutants: Carbon monoxide; • Nitrogen oxides; • Sulfur dioxide; • Volatile organic compounds; • Particulate matter; and • Ammonia.

What are secondary pollutants?

Secondary air pollutants: Pollutants that are formed in the lower atmosphere by chemical reactions. The two examples are ozone and secondary organic aerosol (haze). Secondary pollutants are harder to control because they have different ways of synthesizing and the formation are not well understood.
