Assessment of Heavy Metal Contamination in Sediments along the Jiangsu Lagoon

Abstract:

Abstract: In this study we have worked on the evaluation of heavy metal contamination in the sediments taken from the Jiangsu lagoon and thereby used the Enrichment factor (EF), Pollution load index (PLI), Geoaccumulation index (Igeo), Potential ecological risk index (PERI), Potential ecological risk index (PERI), Potential toxicity response index (PTRI) and Risk assessment code (RAC) and the methods of statistical analysis. The average EF of Zn is found to be less than 2, and the average EF of Cu, Cr, Cd, Pb and Ni are found to be greater than 2 in Jiangsu lagoon.The EF for Pb, Cd and Cr are higher along the Jiangsu lagoon and harbor, which reveals the anthropogenic contribution to the increased content of the surface sediments of the Jiangsu coast. PLI values calculated for Yancheng suggest that this zone is appreciably less impacted by metal pollutants than Nantong. Zn (Igeo(mean)<0), as unpolluted to moderately polluted with Cu (0
