| 摘 要： | 采取烟台近岸海域150个海底表层沉积物样品进行Hg,Cu,Pb,Zn,Cd,Cr,As,Ni元素分析。结果显示,烟台市近岸海域重金属主要富集在芝罘湾(Cd,Cu)、龙口(As,Cr,Cu)及海阳东部(Ni,Pb)一带,而莱州、招远及牟平近岸海域重金属含量较低。单因子、内梅罗和潜在生态危害指数评价结果显示,研究区88%海域的沉积物达到一类标准,轻污染区主要分布在芝罘岛北部及龙口市西部,龙口、招远及烟台市近岸沉积物潜在风险中等。

| Abstract: | Through the determination of heavy metals(Hg,Cu,Pb,Zn,Cd,Cr,As,Ni)in 150 surface sediments in Yantai coastal area,the spatial distribution and pollution have been discussed.Heavy metal pollutants in Yantai are mainly concentrated in Zhifu Bay(Cd,Cu),Longkou(As,Cr,Cu)and the east of Haiyang(Ni,Pb),while Laizhou,Zhaoyuan and Muping is relatively low.In this paper,the evaluation methods of environmental quality are single factor pollution,Nemerow pollution and potential ecological index.The comprehensive evaluation results show that 88%of the sea area in the study area meets the first class standard,and the light pollution area is mainly distributed in the north of Zhifu Island and the west of Longkou City.Longkou,Zhaoyuan and Yantai city are medium potential risky area. |
