领主区最工业化的districts in the state. The heavy industrialization and the increasing urbanization are responsible for the rapidly increasing stress on the water environment of the area. Therefore an attempt has been made to study the physico chemical properties of effluents and to know the pollution load on the environment. Effluent Samples were obtained from various industries such as bulk drug chemicals, textile, and rubber chemicals, vitamin products, agrochemicals, dairy, dye manufacturing, textile processing, polymer, jewelry, construction chemicals, insecticides, paper products and fine chemicals. The effluent samples were analyzed and it is found that, electrical conductivity and T.D.S. varies from 0.43 to 46.5 millisimens cm-1and 280 to 30,225 mg/lit. High T.D.S., low D.O. content, high C.O.D. and conductivity values with high Cl-,SO4-2 , Ca2+, Mg2+, Na+ content indicates highly polluted condition of effluent .Heavy metal analyses were analyzed by Inductively Coupled Plasma (ICPE-9000) Atomic Emission Spectroscopy. It is found that AS, Cu, Cd, CO, Fe, Ni, Zn, Pb and Cr are within the limit prescribed limit prescribed by I.S.I., Hg is beyond the prescribed limit
