| 摘 要： | 以第四纪沉积物厚覆盖区农用地表层土壤汞元素为研究对象,分析了汞的水溶态、离子交换态、碳酸盐态、铁锰氧化态、腐殖酸态、强有机结合态、残渣态等7种形态存在特征,研究表明残渣态的含量比例与全量呈正相关关系,其他6种类型形态含量比例则与全量呈负相关关系,农用地土壤中汞的增量主要为残渣态的汞. |

| Abstract: | The chemical forms of mercury,distributed in the farmland topsoil of the regions covered by thick Quaternary sediments,were synthetically studied on their water solubility phases,exchangeable phases,carbonate phases,Fe-Mn oxide phases,humic acid phases,strong organic phases and residual phases.The results indicate that the percent of the total Hg is positively correlated with that of the residual phase Hg,and negatively correlated with the other 6,and also,the residual phase Hg constitutes the majority of t... |
