Abstract– Agricultural, domestic wastes and industrial discharges have contributed as source of inorganic pollutants in freshwater bodies, that are also a home for many species of edible freshwater fishes. Heavy metals Zinc and Copper are common inorganic components bioaccumulating gradually in different body parts of the fishes, particularly gills and muscles. Consumption of these fishes by people of nearby areas lead to bioaccumulation of toxic heavy metals in the body. In the present study freshwater pond Bara Talab, Bundu, Jharkhand was selected, and bioaccumulation of toxic heavy metals in gills and muscles of two freshwater edible fish Clarias batrachus and Labeo rohita were studied. Concentration of Zinc in gills of Clarias batrachus and Labeo rohita was found to be 2.69±0.8 μg/g and 1.8 ±0.6 μg/g respectively, whereas, concentration of Copper was found to be 1.28 ±0.15 μg/g and 0.48 ±0.09 μg/g respectively. Concentration of Zinc in muscles of C. batrachus and L. rohita was 1.4 ±0.5 μg/g and 0.8 ±0.04 μg/g respectively. Gills showed higher bioaccumulation of both Cu and Zn heavy metal. This result showed that due to deposition of agricultural and domestic waste in Bara Talab, Bundu, freshwater edible fishes are facing the degradation of health as a result of bioaccumulation of toxic heavy metals Zn and Cu.
