摘要
本文通过对南海海域自然环境中表层海水溶解态Cu、Pb、Zn、Cd的分析,讨论了南海表层海水中重金属含量的分布.根据地理环境特征及表层环流结构将南海表层水域分成北部和南部两个重金属背景值海区,并采用统计学方法对海水中重金属的分布类型进行了态性检验,按分布类型分别确定了Cu、Pb、Zn、Cd的环境背景值.
The concentrations and distribution of dissolved Cu, Pb, Zn and Cd in the surface water of the South China Sea are studied in June and November, 1998. According to the geographical environment and circulation in upper layers of the South China Sea,The heavy metal background values area of the surface water can be divided into the north area and the south area. The probability distribution type of the elements is decided comprehensively by using the statistical analysis and the background values of the elements are obtained.
