Abstract
Acute and chronic toxicity of zinc Smelter effluent to some developmen tal stages of freshwater fish, Cyprinus carpio have been studied. Para meters for acute toxicity such as LC50 values, maximum acceptance toxi cant concentration (MATC), Threshold concentration and safe concentrat ion were determined by using static bioassay method. Eggs of C. carpio were found to be more sensitive to zinc effluent as compared to highe r developing stages. Eggs reared in 50% zinc effluent showed abnormal body structure. Juveniles of C. carpio reared under 20% zinc effluent showed histological damage in liver and kidney.
