摘要
利用南极中山站建站时采集的土壤样品，分析了各样品中重金属铜、镉、铅、锌的全量及ＤＴＰＡ代换态含量。结果表明，上述重金属的ＤＴＰＡ代换态含量能集中反映人类活动的影响，是进行南极地区环境影响评价的敏感指标，而土壤全量则因母质成分的差异而具有明显的区域分异，掩盖了本来程度很轻的人为污染。分析结果表明诸科学考察站的燃料烟尘对该地区土壤中的ＤＴＰＡ代换态重金属铜、镉、铅、锌的含量有明显影响。
The total contents and DTPAextracted contents of Cu,Cd,Pb,Zn in soil samples collected near Zhongshan Station when it was built in 1988 show that the DTPAextracted contents of Cu,Cd,Pb,Zn can overshadow the influence of parent materials and reflect the impact of human activities while the total contents of Cu,Cd,Pb,Zn,which are usually used as pollution indexes,are controlled not by human activities but by parent materials.The study shows that scientific stations there had greatly changed the DTPAextracted contents of Cu,Cd,Pb,Zn in the soils as a result of anthropological release and the local wind. The DTPAextracted contents of Cu,Cd,Pb,Zn are sensitive to human activities and can be used for EIA in Antarctica and for the impact assessment of soil environment.
