Abstract

The Vaigai River was highly polluted by various chemicals and heavy metals due to industrial and domestic discharge. These pollutants cause serious damage to the fishes. In the fishes these pollutants gets accumulated in their liver, bone, muscles and kidney. The heavy metal toxicity of the river were analyzed by collecting the fish from various sites of the river and estimation of heavy metals like chromium, cadmium, lead and nickel were done by isolating these organs. Various physico chemical parameters and heavy metal concentration of the Vaigai River water were also analyzed. From the result it was found out that concentration of nickel, lead and chromium were higher than the permissible limit.
