Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. Pollution control
Pollution control is a term used in environmental management. It means the control of emissions and effluents into air, water or soil. Without pollution control, the waste products from consumption, heating, agriculture, mining, manufacturing, transportation and other human activities, whether they accumulate or disperse, will degrade the environment. In the hierarchy of controls, pollution prevention and waste minimization are more desirable than pollution control. In the field of land development, low impact development is a similar technique for the prevention of urban runoff.
CENTRAL POLLUTION CONTROL BOARD
The Central Pollution Control Board (CPCB) is an autonomous body of the Ministry set up in September, 1974, under the provisions of the Water (Prevention and Control of Pollution) Act, 1974. It coordinates the activities of the State Pollution Control Boards (SPCBs) and Pollution Control Committees (PCCs), and also advises the Central Government on all matters concerning the prevention and control of environmental pollution. The CPCB, SPCBs and PCCs are responsible for implementing the legislation relating to prevention and control of pollution; they also develop rules and regulations which prescribe the standards for emissions and effluents of air and water pollutants and noise levels. The CPCB also provides technical services to the Ministry for implementing the provisions of the Environment (Protection) Act, 1986.
