1995年 1 0月调查研究了厦门 金门海域表层沉积物中重金属Cu、Pb、Zn、Cd的含量 ,Cu、Pb、Zn、Cd的平均浓度分别为 1 6 .6、5 2 .6、1 0 4、0 .2 0 5 (× 1 0 -6m/m ,干重 )。根据底质标准 ,Pb、Zn明显超标。从平面分布看 ,厦门岛南部海区(XJ1～XJ4号站 )的重金属含量高于北部海区 (XJ5～XJ7号站 ) ,北部海区又高于东部海区 (XJ9、R1、R2号站 ) ,尤其是南部海区的XJ1、XJ2、XJ3号站其含量明显较高。这一分布特征表明除了九龙江河流对该海域的贡献外 ,西海域的输入也是一个重要的因素。位于东部海区的XJ9、R1、R2号站 ,从XJ9至较靠近金门的R1、R2号站 ,重金属Cu、Pb、Zn、Cd的含量略有回升 ,其来源有待于进一步分析探讨。
The contents of heavy metals Cu, Pb, Zn and Cd in surface sediments of Xiamen Jinmen sea area were investigated in January, 1995. The average concentrations of Cu, Pb, Zn and Cd were 16.6, 52.2, 4,0 .2 0 5 (× 10 -6 m / m, dry weight). According to the sediment standard, Pb and Zn were obviously exceeded. The distribution of heavy metals in the southern sea area of Xiamen Island (stations XJ1-XJ4) is higher than that in the northern sea (stations XJ5-XJ7) and higher in the northern sea than the eastern sea (stations XJ9, R1 and R2), in particular The contents of XJ1, XJ2 and XJ3 in the southern sea area were significantly higher. This distributional feature indicates that in addition to the contribution of the Jiulong River to this area, the import of the West Sea area is also an important factor. The stations XJ9, R1 and R2 located in the eastern sea area slightly rose from XJ9 to stations R1 and R2 closer to Kinmen. The sources of the heavy metals Cu, Pb, Zn and Cd are expected to be further analyzed.
