摘要
2018年9月在象山港布设14个沉积物站位点,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重金属的污染状况和生态危害水平。结果表明象山港海域沉积物铜、锌、铅、镉、铬、汞、砷的含量均符合海洋沉积物质量的第一类标准。重金属铜、铅、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,各站位潜在生态危害系数均<150,表明象山港海域总体处于低生态危害水平。
In September 2018,14 sediment sites were set up in Xiangshan Port.The single item evaluation standard index method,enrichment coefficient method and potential ecological hazard index method were used to evaluate the pollution status and ecological hazard level of heavy metals.The results show that copper,zinc,lead,cadmium,chromium,mercury,and arsenic in the sediments of the Xiangshan Port area meets the first type of marine sediment quality standards.The average enrichment coefficients of heavy metals copper,lead,and zinc are greater than 1,which has a relatively large degree of enrichment.The potential ecological hazard coefficient of heavy metal cadmium is relatively high,and the potential ecological hazard coefficient of each station is<150,indicating that the sea area of Xiangshan Port is generally at a low level of ecological hazard.
