These activities release certain materials which produce pollution in the atmosphere, water & soil. The environmental pollution can be caused by Chemical agents (gases, pesticides, particulates) Physical agents (heat, noise, radiation) or Biological agents (micro – organisms) Pollution produces adverse effect on living as well as on non living materials.

Although the Prob. of controlling air pollution at source is not easy, yet it can be reduced to some extent by taking steps such as, Use of appropriate raw materials, selection of proper sites for industrial units & use of modern techniques for efficient reduction of emission & effluents. Different methods for the control of various air pollutants are as follows:Control of COSome of the
