PHYSICOCHEMICAL CHARACTERISATION OF TREATED TEXTILE EFFLUENT AND ITS EFFECTS ON BIOCHEMICAL CONSTITUENTS OF FRESH WATER FISH, TILAPIA MOSSAMBICAC.N. NOORJAHANAbstract The physico chemical parameters (pH, EC, BOD, COD, TD8, T88, Chromium, Copper and Zinc) of 100% treated textile effluent and its effects on the biochemical constituents present in the gills, liver and muscle of Tilapia mossambica were studied. The results of analysis of physico chemical parameters of 100% treated textile effluent revealed that the parameters such as pH, EC, BOD, COD, TD8, TSS were found to be higher than the permissible limits of CPCB (1995) thereby indicating the high pollutional potential of the effluent. The biochemical estimation revealed that lipid depletion was followed by carbohydrate and protein in all the three organs, i.e., gills and muscle in the decreasing trend exposed to treated textile effluent and gills were most affected compared to liver and muscle.
