| 摘 要： | 对南极长城站地区１０种环境样品中的总砷含量进行了分析测定，并对总砷在不同环境介质中的分布以及与世界其他地区的总砷含量水平进行了比较。结果表明，长城站地区陆地淡水、海水、新降雪以及沉积物、表土等环境样品中的总砷量低于世界背景水平；海洋植物中的砷含量较高，但也不超出世界平均值，地衣、苔藓及帽贝样品中的含砷量高于世界平均水平，说明在极地环境条件下，这两类生物对砷的富集能力较强。

| Abstract: | The total As concentrations in about 10 different environmental samples from the Great Wall Station,Antarctica were determined,the distribution of total As in different envionmental mediums and a comparison with the As levels in other areas in the world were also discussed.The results show that,except lichen,moss and shellfish,in fresh water,seawater,fresh snow,sediments,surface soil and marine plants the total As concentrations are lowwer than the backgroud levels in the world.Lichen,moss and shellfish exhibit(show) a strong As concentrating ability. |
