选取福建省泉州市德化县汤(头)-葛(村)-杨(梅)地区作为研究区 ,通过室内静态实验 ,调节pH值和添加不同量的有机质研究它们对 Hg的累积过程、动力学特征及存在形态的影响.应用双常数动力学方程对H g累积过程进行拟合 ,拟合度达99. 993 3% ,拟合效果好.最后以p H值作为影响因素 ,对该研究区土壤重金属 Hg累积的潜在风险进行评估 ,结果表明该研究区土壤中的重金属 Hg累积已处于高风险 ,应采取一定措施.

This paper chose the area of Tang-Ge-Yang ,Dehua county ,Quanzhou city ,Fujian Province as the study area .Through the static experiments and the regulation of different pH value and organic matters ,it studied their effects on accumulation process ,dynamic characteristics and existing forms of mercury .Then it used two-constant equation to fit the accumulative process of mercury .The findings showed that the fitting degree reach to 99.993 3% ,an effective point .Finally ,this paper assessed the potential risk of heavy metal element accumulation of mercury in soil by taking pH value as the influence factor .The results indicated that the Hg accumulation in soil of the study area had been in high risk ,and some measures should be taken .
