Abstract

Heavy metals are dangerous because they tend to bioaccumulation. Bioaccumulation means an increase in the concentration of a chemical in a biological organism over time, compared to the chemical's concentration in the environment. In the present study in Ennore estuary, Concentration of metals shows significant variability and range from 1.7 to 3.7% for Fe, 284–460 μg g −1 for Mn, 148.6–243.2 μg g −1 for Cr, 385–657 μg g −1 for Cu, 19.8–53.4 μg g −1 for Ni, 5.8–11.8 μg g −1 for Co, 24.9–40 μg g −1 for Pb, 71.3– 201 μg g −1 for Zn and 4.6–7.5 μg g −1 for Cd. The present study confirming that the concentration of metal from our result is comparatively high for lead, cadmium, and cobalt. The concentration ranges will pose serious threat to the life of biota or man as a consumer.
