| 摘 要： | 本文利用“深圳—珠海近岸海洋地质环境调查及地质灾害防治的调查研究”项目海水样品有害重金属测试数据,分析了深圳大鹏湾、珠江口海水有害重金属的分布特点,并与沉积物中的有害重金属含量进行综合比较,最后根据国家标准进行了水质评价。结果表明,研究区有害重金属含量、比例以及分布特征不尽相同,深圳大鹏湾超标有害重金属主要是Cr^＋6、Cu、Pb,珠江口则主要是Pb、Cr^6＋,其中以Pb是超标最为严重,其来源不仅与地球化学本底值有关,也与人类活动直接联系。

| Abstract: | Based on the measured data from the project sponsored by the MLR,"Investigation and Research on Shenzhen-Zhuhai Nearshore Marine Geological Environment and Geological Hazards and their Prevention",the dissolved harmful heavy metals in Dapeng Bay of Shenzhen and the Pearl River Estuary are analyzed and discussed in this paper.The results show that their concentrations and compositions are different and are related to their physical and chemical environments.The concentrations of the dissolved metals in the water are lower than those in the surficial sediments and borehole samplers except Pb,Cu,and Cr in the Pearl River Estuary.Finally,water quality assessment is conducted according to state standards which reveals that Cr~(+6),Cu and Pb in Dapeng Bay and Pb and Cr~(+6) in the Pearl River Estuary are below the standards,which is directly related to human activities. |
