连云港近岸海域沉积物重金属潜在生态危害评价

Assessment on potential ecological risk of heavy metals in sediment in Lianyungang coast

采用Hakanson潜在生态危害指数法对连云港近岸海域沉积物重金属生态危害程度进行了评价。结果表明,连云港近岸海域沉积物属于轻微污染,生态质量总体较好,沉积物中As、Cu相对于Hg、Pb、Cd污染水平较高。

In this paper, the assessment of the potential ecological risk status of heavy metals in the sediment in Lianyungang coast was made by the method, which Hakanson L applied to. The results shows that the potential ecological risk in the sediments in Lianyungang coast is low, the ecological quality is fine on whole, the contamination degree of As and Cu is higher than Hg, Pb, Cd in the sediment.
