Abstract

In the present study groups of fishes exposed for 96 hr to zinc+cadmium, zinc+copper, zinc+endosulfan, zinc+cadmium+copper+efldosulfan and zinc+cadmium+copper+ dimethoate combinations and it has been observed that some effects of metals may be prevented by the simultaneous administration of other metals. Bioaccumulation of Zinc decreased when the fish were exposed to zinc+ copper, zinc+cadmium+copper+endosulfan and zinc+cadmium+copper+dimethoate combinations as compared to fishes exposed to Zinc alone. 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 Muscle>Kidney> Gills >Liver>blood.
