Human population has increased enormously in the last century due to which the demand of food, water, home, electricity, roads and automobiles etc. has increased many fold. These demands are creating tremendous pressure on the natural resources and causing environmental pollution (of Air, Water and Soil etc.) On one hand we need to check the degradation and depletion of natural resources, and on the other the level of Pollution is to be controlled without halting the process of development.
Pollution is an undesirable change in physical, chemical or biological characteristics of air, land, water or soil. The agents that bring about such an undesirable change are called Pollutants.
For the classifi cation of pollution/ pollutants various parameters are used,
• On the basis of the part of environment affected – e.g., Air pollution, water pollution, soil pollution etc.
• On the basis of origin of pollulants- e.g., Natural pollutants and Anthropogenic pollutants
