Abstract: Water contamination is one of the seriously concerned pollutions that affect the ecosystem with high concentration of the heavy metals. The accumulation of heavy metals which are byproducts of industries have created great health hazards in aquatic organisms particularly fishes. A study was conducted between January 2016 to December,2016 to assess the concentration of Cu, Cr, Pb, Hg, Fe and Zn in liver and muscle of selected food fish Channa marulius from Kolleru Lake, Andhra Pradesh. The concentration of metals in the liver was significantly higher than that of the muscle. The highest metal concentrations found in the organs of the fish lead to the oxidative stress which shortens the lifespan and quality of the meat of the fish postulated primary results from anthropogenic activities, fish/shrimp pond effluents and sewage water and effluents from local industrial activities in the Kolleru Lake. Target Hazard Quotient (THQ) was calculated to evaluate the health risk of fish consumers in the Kolleru area.
