摘　　要：为了解宁波舟山港北部海域生态风险水平,采用单项评价标准指数法、富集系数法和潜在生态危害指数法评价宁波舟山港北部海域重金属的污染状况和生态危害水平。结果表明调查海域沉积物锌、镉、铬、汞的含量均符合海洋沉积物质量的第一类标准,而铜、铅、砷的站位超标率均为10%。重金属铜、铅、镉和锌的平均富集系数>1,具有相对较大的富集程度。重金属镉的潜在生态危害系数相对较高,所有站位潜在生态危害系数均<150,表明调查海域总体处于低生态风险水平。In May 2019,ten sediment sites were deployed in the northern sea of Ningbo Zhoushan port,.The single evaluation standard index method,the enrichment coefficient method and the potential ecological hazard index method were used to evaluate the pollution status and ecological hazard level of heavy metals.The results show that the contents of zinc,cadmium,chromium,and mercury in the sediments of the surveyed seas are all in line with the first category of marine sediment quality standards.The over-standard rates of copper,lead and arsenic are all 10%.The average enrichment coefficient of heavy metals copper,lead,cadmium and zinc is greater than 1,which has a relatively large enrichment degree.The potential ecological hazard coefficient of heavy metal cadmium is relatively high,and the potential ecological hazard coefficient of all stations is less than 150,indicating that the surveyed sea area is generally at a low ecological hazard level.
