In the present study groups of fishes exposed for 96 hr to zinc+cadmium, zinc+copper, zinc+endosulfan, zinc+cadmium+copper+endosulfan and zinc+cadmium+copper+dimethoate combinations and it has been observed that the interaction between one metal with another metal can be antagonistic or synergistic. In some cases no interaction among them was noticed. Experiments on fish have shown that some effects of metals may be prevented by the simultaneous administration of other metals .The metal concentration decreased as compared to fishes exposed to zinc alone. Bioaccumulation of zinc decreased when the fish were exposed to zinc+cadmium combination. Results clearly show that the level of accumulation of zinc in different tissues (Muscle, liver, Gills , Kidney) and blood in the two types of exposures (individual and group exposure) varied in order Gills>Blood>Kidney >Liver>Muscle.
