    山东丁字湾表层沉积物重金属分布及污染评价

    DISTRIBUTION AND ENVIRONMENT ASSESSMENT OF HEAVY METALS IN THE SEDIMENTS OF DINGZI BAY, SHANDONG PROVINCE

      摘要
    • 摘要: 通过对丁字湾海域126个表层沉积物重金属(Hg、Cu、Pb、Zn、Cd、Cr、As、Ni)含量的测定及分析，采用潜在生态危害指数法、内梅罗指数法、地质累计指数法等多种评价方法，对研究区海域环境进行评价。结果表明，丁字湾海域表层沉积物中重金属含量主要集中在丁字湾湾口周边海域，Hg、Cd、As、Pb、Cu、Cr、Zn平均含量分别为0.02、0.08、8.38、15.31、11.49、60.96、46.42 μg/g。利用不同的评价方法，可以看出丁字湾海域表层沉积物重金属元素总体呈未污染—轻微污染的现状，这与区内砂质沉积物广泛分布以及不活跃的人类活动密不可分。

       

      Abstract: Based on the concentrations of heavy metals (Hg, Cu, Pb, Zn, Cd, Cr, As, Ni) of 126 surface sediments collected from Dingzi Bay, Shandong province, the method of ecological hazard index is used in this paper to evaluate the pollution of sediments. The content of heavy metals and the distribution patterns and pollution status of the surface sediments are discussed. Results show that the average contents of Hg, Cd, As, Pb, Cu, Cr and Zn in the surface sediments of Dingzi Bay are 0.02, 0.08, 8.38, 15.31, 11.49, 60.96 and 46.42 μg/g, respectively, indicating that the ecological hazard of the area is limited in a reasonable range. This is the first time to evaluate the environmental quality objectively by heavy metals in Dingzi Bay according to the local needs. As an important contribution it may serve the local economic construction and marine ecological civilization.
