摘要：

本文以１９９２／１９９３年度中国第九次南极考察期间对南极乔治王岛的表土、地衣、苔藓等样品的分析资料为基础，研究探讨了８种无机重金属元素、５种有机污染物的浓度水平。其结果表明，重金属在三种环境样品中的含量分布存在着明显的差异；地衣、苔藓两种植物呈现对不同重金属元素的不同富集能力；∑６６６、∑ＤＤＴ和ＰＣＢｓ及油的沾污亦很明显。本文还对污染物质的来源、南极环境样品历次调查分析的结果以及世界部分地区的背景水平进行了讨论和比较

Abstract:

Based on the analytical results of surface soil,lichen and moss sampled from King George Island,Antarctica during 1992/1993,the concentration levels of 8 heavy metals(include As,Se) and 5 organic pollutants are discussed.It is indicated that the content distribution of heavy metals in three environmental samples is very different.Lichen and moss showed different concentrating ability to different heavy metals.The contamination of 666,DDT,PCBs and Oil is very obvious.The source of pollutants and a comparison with results of other researchers and the background level in some areas in the world are also discussed in this paper.
