Air pollution can be defined as any undesirable change in the physical, chemical or biological characteristics of air.
Agents which cause these undesirable changes are referred to as pollutants.
Air pollutants can be gaseous compounds such as sulphur dioxide, carbon monoxide, etc, particulate matter such as dust or volatile organic compounds such as trichloroethylene, chloroform, etc.
The sources from which the air pollutants are released into the atmosphere can be broadly categorised as -
- Natural sources - which do not involve any human intervention, such as volcanic eruptions, pollens released by flowering plants, etc.
- Anthropogenic sources - which involve human intervention such as exhaust from automobiles, factories, cigarette smoke, etc.
