The transfer of anthropogenic chemicals and squanders within the aquatic environment postures genuine danger to the human wellbeing. In this period of worldwide industrialisation human being is concentrating on their extravagant life fashion uninformed of their botches of arranging heavy metal toxins in nature. These pollutants are returning back to them through food chain. A major toxin is lead derivatives in water-bodies which are not as it were influencing the aquatic ecosysytem but too aggravating harming people straightforwardly or in a roundabout way by biomagnification. The present study was pointed to assess the impacts of heavy metal lead on Channapunctatus. The fishes were exposed to sub-deadly concentration of 5 ppm of lead acetic acid and were inspected after 30 days of exposure. The comes about appeared tall aggregation of lead within the liver, kidney, gills and presence of micronuclei as an evidence of genotoxicity.
