We determined the heavy metal concentrations and evaluated the pollution status of 213 surface sediment samples collected from the nearshore zone of southern Jiangsu Province, China. The distributions of lead (Pb) and zinc (Zn) were similar, and their concentrations were highest in tidal creeks dominated by fine-grained sediments, such as the Dawanhong and Wangcanghong creeks and the outer part of Lanshayang Creek. The spatial distributions of chromium (Cr) and cadmium (Cd) were similar, with high concentrations south of Yangkou Port and Haozhi Port. Copper (Cu) concentrations were high off the coast of Rudong. The sediments were not polluted by Cu, but were weakly polluted by Cd, Cr, Pb, and Zn. The results of principal component analysis indicated that Pb and Zn were mainly from natural sources, Cd and Cr were from anthropogenic sources, and Cu was from a mixture of natural and anthropogenic sources.
