摘要: 本文通过对大庆城郊北二十里泡沉积物沉积物重金属含量的分析测定,结果表明主要重金属在各点位含量均超过清洁对照点,将全区域土壤重金属元素背景值作标准,北二十里泡湿地的沉积物中Hg、Zn、Cu、Cd、Pb等元素超标较多。只有Hg和As在个别点位低于标准。聚类分析表明,北二十里泡沉积物重金属中Zn、Pb、Cu可归为一类型,Hg 、Cr、Ni归为一类型,Cd、As归为一类型。在北二十里泡沉积物各采样点中,B5、B11~B18可归为一类型,B6归为单独类型。

Abstract: This paper dealt with the contents of heavy metals in surface sediments from Beiershili pool wetland, The result showed that the contents of heavy metals have excessed the cleaned site, we found that the contents of Hg、Zn、Cu、Cd、Pb were very high in sediment of Beiershili pool wetland , which the cluster analysis showed that Zn、Pb、Cu may be a type, Hg 、Cr、Ni may be a type, Cd、As may be a type in the heavy metals. The B5、B11~B18 may be a type, B6 may be alone type in the sampling sites.
