Artificially contaminated soils that were contaminated by mercury based on 100 ppm ,10ppm as mercury concentration were made by using typical soil in Japan( Kuroboku soil, Brown forest soil, Red yellow soil) with stabilization of 6 month. These soils were utilized almost 3months in our environmental factor incubation experiments, and then we were investigated as for chemical changes of mercury in each soils. As a result of experiments, the variations of total mercury concentrations of each soil were not recognized in comparison with starting point of the incubation experiment. However, methylmercury content of Kuroboku soil(100ppm) was clearly increased chronologically. In case of 10ppm, methylmercury concentration of Redyellow soil was higher than other soils. Also, dissolved mercury concentrations of Redyellow soils (100ppm, 10ppm) were higher than other soils that were contaminated by mercury artificially.

基于100 ppm污染的汞污染的人为污染的土壤是通过在日本使用典型的土壤（Kuroboku土壤，棕色森林土壤，红色的黄色土壤），稳定为6个月，从而使汞浓度为10ppm。这些土壤在我们的环境因素孵化实验中使用了几乎3个月，然后研究了每种土壤中汞的化学变化。通过实验，与孵育实验的起点相比，未识别每种土壤的总汞浓度的变化。然而，kuroboku土壤（100ppm）的甲基汞含量在时间顺序上明显增加。在10ppm的情况下，红色土壤的甲基汞浓度高于其他土壤。同样，溶解的红绿色土壤（100ppm，10ppm）溶解的汞浓度高于人工污染的其他土壤。
