Heavy metal concentrations in surface waters and sediments of Shanghai port were measured to analyze the spatial distribution characteristics, sources and pollution degrees. The southern Shanghai port was heavily polluted by Cd, Pb, Cr and Cu in water, and the concentrations of Pb, Hg and Zn in sediments exceeded Effects Range Low. Cu, Pb, Cd and Cr in water were positively correlated in group, and they probably derived from industrial and domestic sewage, fossil fuel burning and vehicular pollution and represented 82.47 % of the contribution. Zn, Hg and As contaminations represented industrial and agricultural effluent sources and accounted for the remaining 17.53 %. Heavy metal pollution of Yangshan Port water was at high pollution, and the remaining sites were at low pollution. Most of the sampling sites were at moderate ecological risk in sediments, and the pollution of Cd, Hg and Zn were serious.
对上海港地表水和沉积物中的重金属浓度进行了测定，以分析其空间分布特征、来源和污染程度。上海港南部水域受到镉、铅、铬和铜的严重污染，沉积物中铅、汞和锌的浓度超过了效应范围低值。水中的铜、铅、镉和铬呈正相关，它们可能来自工业和生活污水、化石燃料燃烧及车辆污染，贡献率达82.47%。锌、汞和砷污染代表工农业废水来源，占比17.53%。洋山港水域重金属污染处于高污染水平，其余站点处于低污染水平。沉积物中大部分采样点处于中等生态风险，镉、汞和锌污染严重。
