摘要(Abstract)：

使用改进的BCR连续提取法和电感耦合等离子质谱(ICP-MS),测定夹皮沟金矿区土壤样品中汞元素的赋存形态及含量。结果表明,三个深度的土壤汞元素形态分布趋势相似,均以残渣态为主,其次为可氧化态和可还原态,酸溶/可交换态和水溶态所占比例较少,各形态汞的分配系数依次为:残渣态(48.28%)>可氧化态(25.68%)>可还原态(13.35%)>酸溶/可交换态(8.38%)>水溶态(4.33%)。垂直方向上,20~40 cm的中层土壤中的汞含量略高于0~20 cm的表层土壤,40~60 cm的下层土壤则含量最低。不同深度土壤中的有效态汞与总汞的含量具有较高的相关性,但三层土壤不具有相同的相关趋势。
