What is Air Pollution

What is Air Pollution?

Air Pollution is contamination of the air by noxious gases and minute particles of solid and liquid matter (particulates) in concentrations that endanger health.

Air Pollutants are any solid, liquid or gaseous substance present in the atmosphere in such concentration as may be or tend to be injurious to human beings or other living creatures or plants or property or environment. Air Pollutants can be solid particles, liquid droplets or gases. Furthermore, a pollutant can be of natural or man-made origin.

Common Air Pollutants

     Carbon Monoxide
     Nitrogen Dioxide
     Ground Level Ozone

     Sulphur Dioxide
     Particulate Matter

Classification of Air Pollutants

Primary Pollutants

Primary pollutants are chemicals directly emitted into the air at harmful concentrations.

Examples: CO2, CO, SO2, NO2, NOX, CH4, Hydrocarbons & Particulate Matter.

Secondary Pollutants

These pollutants are formed from the reaction of Primary Pollutants with other chemicals in air.

Examples: Ground level ozone, Photochemical smog, acid rain, Peroxyacetyl Nitrate (PAN) etc.


Outdoor air pollution has been recognized as a source of discomfort for centuries as smoke, dust and obnoxious odors.


Indoor Air Pollution is 5 – 100 times more than the outdoor air pollution. Indoor air pollution is a concern in the developing countries
