Abstract: The environment is everything that surrounds us and gives us life and health. The aim of the study is to determine the accumulation of heavy metals in fish Cyprinus carpio in river Bhavani. The accumulation of metals in water were observed and bioaccumulations of heavy metals like Cd, Cr, Cu, Fe, Pb, Zn, Mg, in fresh water fish were evaluated. The evaluations were calculated in percentage. Toxic pollution arrives from heavy metals, such as cadmium, chromium, copper, iron, lead, zinc, magnesium. These metals pollute the surface water and ground water. It affects the fish and human beings. The accumulation of metals in tissues like gill, liver, intestine, kidney and muscle were observed and evaluated. The changes in river and fish were noted.

Keywords: Cyprinus carpio, Bhavani river, metals- Cd, Cr, Cu, Fe, Pb, Zn, Mg, Accumulation, Bioaccumulation
