摘要： 采用原子吸收光谱和等离子体发射光谱等现代仪器分析方法对大兴安岭泥炭垂直剖面中Cu、Pb、Zn、Cd、Hg、Cr、Ni、Co、Mn、Sr、Ba、B等12种微量元素进行了测定,结果表明,大兴安岭地区古莲、图强泥炭地和同一泥炭地沼泽泥炭发育的不同阶段,微量元素含量分布规律不十分明显,与俄罗斯典型同类泥炭相比,Mn含量俄罗斯泥炭明显高于大兴安岭泥炭,Zn、Co、B含量大兴安岭泥炭明显高于俄罗斯泥炭。大兴安岭高位泥炭中,微量元素特别是与人类活动密切相关的重金属,由下层到上层其含量有明显增高的特点,具有较重要的环境意义。通过不同地区高位泥炭微量元素地球化学谱的研究,可以再现人类活动影响下大气污染的历史。

Abstract: Samples of peat were collected from the Da Hingan Mountains. The contents of trace elements (including Cu, Pb, Zn, Cd, Hg, Cr, Hi, Co, Mn, Sr, Ba, B) in the vertical sections were measured with modern analytical methods (AAS and ICP). The results show that the dispersion regularity of trace clement concentrations was not very clear in Gulian peat and Tuqiang peat and in different stages of the same type of peat. Compared with the same type of Russian peat, the contents of Zn, Co and B in the Da Hingan Mountains was higher, but the content of Mn was obviously lower. In the high peat, the contents of trace elements increased from bottom layer to surface layer, especially for some heavy metals having close relationship with human activities. Studies on trace elemlent geochemistry spectrums of peat in different areas help to reconstruct the history of air pollution and have great environmertal significance.
