Heavy metal analysis of three gastropod species in pondicherry south eastcoast of india

This study was aimed to analyze six heavy metals such as Cu, Zn, Mg, Lb, Cd, Cr. Were estimated in sediments, shells, tissues of three gastropod Rapana rapiformis, Chicoreus virgineus, and Hemifusus pugilinus, and analyzed in AAS, We ensure that the heavy metals present in sediment is high concentration in this study area fallowed by tissue and shell of gastropod, tissue and shell has the homogeneity, samples Cr not present. But tissue samples having the diverge the concentration as well as order, the high concentration of heavy metals present in the sediment is due to the anthropogenic inputs and fishing activity, this study conclude that Evan though the accumulation of heavy metals is in low concentration we should take some measurements to safe the our marine system in the form of reducing the pollution loads in to the marine environments.
