Distribution and source of heavy metals in the surface sediments from the near-shore area, north Jiangsu Province, China.
Samples of surface sediment and vibrocore were collected in the near-shore area of north Jiangsu Province for grain size, elements, (210)Pbexcess and (137)Cs analyses. In our study area, the diversity of metal concentration was controlled not by the grain size, but by the source. The element content of the old Yellow River Delta was used as baseline for our study area. Geoaccumulation indexes indicate that no station was polluted by Cu, Pb, Zn and As, but the Igeo values of As were close to zero in some stations. Slight pollution caused by Cd was observed in some stations. Correlation and enrichment factors suggest that Cu, Pb and Zn are lithogenic in origin, while As and Cd are mixed in origin. Especially, in some polluted stations Cd was obviously anthropogenic in origin.
