Author(s): G. Ambedkar and M. Muniyan

The accumulation of metals like Chromium, Cadmium, Copper, Lead and Zinc in five freshwater fish Megalaspis cordyla, Heteropneustes fossilis, Tilapia mossambica, Mystus vittatus and Mugil cephalus, from vellar River Tamil Nadu, India, January 2010 to June 2010 were investigated in the present study. The levels of metals accumulated were analyzed through the Atomic Absorption Spectrophotometer. The results shows the Cr concentrations were the maximum levels followed by Cd > Cu > P b >Zn among the metals analyzed, Zn were the lowest concentration in the five fish species. The levels of metals accumulated by the fish are may be due to increased fertilizers, agricultural wastes, industrial effluents and some anthropogenic activities. The magnitudes of metals concentration were discussed with the available literature.
