Investigation of Heavy Metal Pollution Elucidated from Biomonitoring along Lianyungang Coast

To evaluate the marine heavy metal pollution, Hg, Zn, Pb, Cd, Cr of bivalves and fishes collected from cultivating areas and natural catching along Lianyungang coastal waters were analyzed. Results show that Hg, Zn, Pb, Cd were present in the marine organisms except Cr below the detection limits. The content of Pb of bivalves from cultivating areas and that of bivalves and fishes from natural catching exceeded the standards, while the rest was below the prescribed legal limit, indicating that Pb has become the potential health risks. Anthropogenic activities may have introduced significant amounts of Pb into the marine environment.
