Abstract 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.
