摘要
分析了2005年—2015年其中4年东碇临时海洋倾倒区及邻近海域表层沉积物中Cu、Pb、Zn、Cd、Hg、As共6种重金属含量及时空分布特征,采用潜在生态风险指数对重金属污染现状及潜在生态风险进行评价,结果表明:历次调查重金属含量均较低,符合国家海洋沉积物质量一类标准,Cd、Cu的空间分布不均匀,其余4种重金属指标空间分布差异不大,As、Pb、Zn富集程度相对较高,Cu、Hg、Cd较低。东碇临时海洋倾倒区及邻近海域沉积物重金属综合潜在生态风险处于较低水平,风险排序为As>Pb>Hg>Cd>Cu>Zn,其中As、Pb和Hg为主要潜在生态风险因子。
A comparative analysis on the content and distribution of heavy metals in surface sediments of Dongding temporary marine dumping area and its adjacent sea area was conducted in2005,2010,2013 and 2015,and the pollution status and the potential ecological risk of heavy metals in Dongding temporary marine dumping area were studied using Hakanson potential ecological risk index method.The results showed that the concentrations of heavy metals in the surface sediments were relatively low and in accord with the first class of the marine sediment quality of National Standards.The concentrations of Cd and Cu distributed on space inhomogenous,but the spatial distribution of Pb,Zn,Hg and As varied slightly.The accumulating degree of As,Pb and Zn appeared high among all these heavy metal in surface sediments,and that of Cu,Hg and Cd lower.The overall level of potential ecological risk of heavy metals in the sediments was light;the levels of potential ecological risk of heavy metals were followed from high to low by As>Pb>Hg>Cd>Cu>Zn,As,Pb and Hg was the key factor of the potential ecological risk in surface sediments.
