东方亚种大鸨越冬种群粪便中的重金属元素分析

Heavy Metal Elements in Otis tarda dybowskii's Feces in Wintering Period

采集并分析了2012年1-2月间陕西黄河湿地自然保护区的大鸨（Otis tarda dybowskii）越冬种群粪便样品中9种重金属元素（Mn、Cd、Cr、Cu、Ni、Pb、Zn、As、Hg）含量，其中 Mn含量最高，为174.55 mg∕kg；Zn含量次之，为57.46 mg∕kg；Cd、Hg含量较低，分别为0.35、0.05 mg∕kg。大鸨粪便相对于其他鸟类Cd、Pb含量偏高，分析了鸟类粪便可作为环境重金属污染监测指标的可行性。

From Jan to Feb, 2012, 9 kinds of heavy metals （Mn, Cd, Cr, Cu, Ni, Pb, Zn, As, Hg） in the feces of the wintering ecology of Otis tarda dybowskii from the Yellow river wetland in Shaanxi province was surveyed. The results showed that the highest content of heavy metal was Mn （174.55 mg∕kg）, followed by Zn （57.46 mg∕kg）. The lower content of metals were Cd and Hg, with 0.35 mg∕kg and 0.05 mg∕kg, respectively. The contents of Cd and Hg in the feces of Otis tarda dybowskii were higher than that of other birds. The feasibility on the bird feces as environmental monitoring indicator was discussed.
