The river Ganga is one of the major recipients of industrial effluent and domestic wastes in India. The present work deals with the study related to bioaccumulation of heavy metals copper (Cu), chromium (Cr), lead (Pb), zinc (Zn), cadmium (Cd) and mercury (Hg) in the organ muscle, gill and liver of Cyprinus caprio collected from the river Ganga at two different sites Kanpur and Allahabad (Utter Pradesh, India) in year 2018-2019. After analysis it was found that the fish C. caprio of Ganga River at Kanpur site have more heavy metal bioaccumulation compared to Allahabad site. At both the study site, the bioaccumulation of heavy metals in muscle and gills was found in the following order respectively: Zn > Pb > Cu > Cr > Cd > Hg; while the order was different in liver: Pb >Zn >Cu > Cr > Cd > Hg. Results indicate that the level of heavy metals in all organs of fish were higher at the Kanpur site in comparison to Allahabad site. Out of the all analyzed heavy metals, Zn was accumulated maximum in muscle (24.35±0.29 µg/g) and in gill (32.45± 0.28 µg/g), while Pb was maximum in liver (28.65±0.49 µg/g). The results of bioaccumulation level thus indicate that fish at the Kanpur site suffers more from heavy metals pollution than that of Allahabad site.
