摘　　要：以长春、南京的土壤汞异常和东营研究区的区域地球化学调查资料为例,采用元素相关关系法首先确定土壤中汞的基准值,在此基础上确定汞的累加量,取得了满意的结果。进一步的研究结果表明,汞的累加与土壤中出现的辰砂具有一定关系。Hg accumulation in soil around urban areas is one of the most serious problems in environmental geochemistry.However, no effective method is available for determining the accumulative amount of Hg in Hg anomalous areas, and the conclusion on the mode of occurrence of Hg is questionable.In this paper,the correlativity method of elements was used to determine the baseline of Hg in soil,and then to determine the Hg accumulative amount according to this baseline and the Hg content in soil.The results show that Hg accumulation is to some extent related to cinnabar.

关 键 词：城镇地区 Hg的累加量 元素相关关系 辰砂
