本文运用部分连续萃取不同地球化学相的化学分析方法，对高汞区、人为汞污染区和背景参考区五个采样点土壤样品的七种汞形态进行了分析。研究表明，人为汞污染和地质作用都会造成土壤中汞的富集，但这两类土壤中汞的相态分布有明显的差别。 In this paper, seven kinds of mercury speciation of soil samples from five sampling sites of high mercury zone, artificial mercury pollution zone and background reference zone were analyzed by chemical analysis methods of partial continuous extraction of different geochemical phases. Studies have shown that both human mercury pollution and geological effects will lead to the enrichment of mercury in the soil, but there is a clear difference in the phase distribution of mercury between the two types of soil.
