Pollution of water resources is a serious and growing problem, despite the existence of relevant legislation. Genotoxic studies of effluent pollutants are very important as they tend to accumulate in aquatic animals. Thus use of aquatic organism to detect the genotoxicity is very useful in environment monitoring. Ramgarh Lake is an important water body of Gorakhpur, U.P. India, which received untreated effluents from different sources of Gorakhpur city. It covers an area of 723hectares, with a circumference of 18 kilometers. The aim of the Present study was to evaluate the toxic impact of these effluents on water quality as well as genotoxic effects on fish. Micronuclei test was employed to study genotoxicity inhabiting in lake. A significant (p<0.05) increment in number of micronuclei were found in fishes directly caught from different sites of lake. Seasonal variation in Physico-chemical parameters (i.e. Temperature, pH, DO, BOD, COD, TSS, and TDS) of water body also measured on basis of American Public Health Association (APHA) method. All these parameters were much higher than the tolerance limit recommended by Central Pollution Control Board of India.
