| 摘 要： | 探讨了芜湖燃煤电厂周边随距电厂水平方向、垂直剖面土壤中砷汞总量及形态分布特征,并分析了土壤中砷汞与理化性质之间的相关性。结果表明:土壤中As、Hg的变幅分别为3.821～19.264mg/kg,0.025～1.696mg/kg,平均含量分别为6.671mg/kg和0.212mg/kg。As、Hg含量总体分布特征为:距电厂1km处最大,距电厂1km距离内次之,距电厂1km以外,随距离增大而减小,其中汞随距离衰减明显。土壤汞含量在东南-西北(SE-NW)主导风向上明显大于东北-西南(NE-SW)非主导风向,而As含量在不同风向上基本无差异;土壤汞含量随剖面深度的增加明显减少,而砷在剖面上的分布规律不明显。土壤中砷主要以硫化物态和残渣态存在,而汞以残渣态和腐殖酸结合态为主。表层土中As、Hg与理化性质之间存在不同程度的相关性。 |

| Abstract: | This paper discussed As and Hg total concentrations and form distribution characteristics of soil in horizontal level and vertical section,along the coal-fired power plant in Wuhu,then analyzed the correlation between As,Hg and physicochemical characteristics of soil. Results showed:As concentrations in soil ranged from 3.821 to 19.264 mg/kg,with an average of 6.671 mg/kg; Hg concentrations in soil ranged from 0.025 to 1.696 mg/kg,with an average of 0.212 mg/kg. The overall distribution characteristics of A... |
