Pollution can be of any form like chemical substances, heat, noise, and many other things. Pollutants are the components of pollution. It can be either natural substance or chemical substance or energy substance. A pollutant is a waste material that pollutes air, water or soil. Three factors determine the severity of a pollutant: its chemical nature, the concentration and the persistence.

Noise pollution is caused by high sounds used by vehicles, factory sounds, high frequency sounds and etc.

Thermal Pollution and Radioactive contamination is caused by using the Thermal products and radio active components to make weapons research, wars and etc.

Effects of pollution:
Due to pollution we are facing many problems like global warming, hole in the ozone layer, many diseases caused due to pollution, and etc.

Pollution Control: It is the one of the ways used by the countries to stop pollution or lessen the effects of pollution. Some of the pollution control measures are recycling, Reusing, mitigation, Waste minimisation, usage of more natural resources, green house gases and etc.
