摘 要:探讨了长白山圆池泥炭常量和微量元素的分布规律。利用荷兰wardenaar泥炭采样器野外采取四个新鲜泥炭剖面,现场用不锈钢面包刀从上至下按1~2cm间隔准确分层取样。针对圆池特殊的自然地理条件,应用澳大利亚产型号为GBC-906原子吸收分光光度计分析了Al、Ti、Mn、Fe、Pb、Zn、Cu;应用日本岛津产型号为7500ICP等离子体发射光谱仪分析了Ca、Mg、Na、K等元素在不同类型泥炭剖面的积累。研究分析了不同泥炭剖面所测元素的分布趋势及富集状况,结果表明:高位泥炭剖面Mn、Zn和Pb由下层至上层含量有明显增高的特点,其在表层的富集,表明该地区大气污染的环境问题有加重的趋势。This article discussed the distribution of major and trace elements of peat in Yuanchi, Changbai Mountain. Four profiles were collected with Wardenaar peat sampler produced in Netherlands. Each sample was cut into 1 ~ 2 cm at the present. As far as the special physical conditions in Yuanchi are concerned, the content of major and trace elements( Na,K,Mg,Ca, Al,Ti,Fe,Mn,Zn,Pb,Cu )were determined among different peat bogs. The elements distribution with depth in each peat profile was fully analyzed. Also we have analyzed the enrichment of different elements in peat profiles. Through the calculated M/Ti( M refers to Na、K、M、Ca、 Al、Ti、Fe、Mn、Zn、Pb、Cu) ratio, compared with ratio of M/Ti collected from literature, we concluded the differences among different peat bogs. The increasing content of Mn,Zn and Pb from bottom to them in present environment, which has profound implications top in peat profiles proves the increasing pollution of for environment.
