摘要
本文报导了南极长城湾沉积物中重金属的分布。论述沉积物中重金属的含量范围,分布特征和它们的富集趋努。而且,还探讨了沉积物中重金属元素的物质来源。
The determination results of heavy metals in the sediment from the Great Wall Bay in Antarctica have been reported in this paper. The content, distribution character and their source of heavy metals in the sediments were discussed.The content of organic compounds in the sediments was high from the bay. They exceeded the environmental pollution standard.'Mercury and grain size in marine sediment presented positive interrelation. Copper, lead, zinc and cadmium showed the trend concentrated at diffrent degrees.
