Solubilization of mercury in soil and chemical changing of mercury species in soil by variety change of basic characteristics of soil

To carry out this投资，我们开发了新的分析方法for determination of methylmercury level in water samples dueto modify the Akagi method. Thenwe were to understand mercury behavior between mercury level in soil and soluble mercury levelthrough this investigation by using a new method which was developed by us，Akagi method. The results are as follows In The case of a new analytical methymercurylevel about water samples这是可能的分析methymercury by using 200ml as sample. In case of soils which were takenin Guiyun China，here is good correlation between total mercury level in soil and methymercury level in soil（r=0.89） Basically，there is no correlation between soluble total mercury level in soil and solublemethylmercury, Although, in the case of soluble total mercurythere is a little correlation total mercury level in soil and soluble total mercury，however, completely,there is no correlation methymercury level in soil and soluble methylmercury. Especially，the case of soluble methylmercury这似乎有一个特殊的behavior on soil. As a result，there is good correlation between soluble methylmercury and EC（electronic conductivity）soil(r=0.69) The case of Methylation in soil，这是受soil species based on each soil characteristics. In present study，the highest methylmercury accumulation of soil is Kuroboku soil. Supposing，each soil conditions are very stablesoil条件和mercury behavior in soil easily changed by adding an another environmrntalfactors such as sun light, temperature so on

To carry out this investigation, we developed a new analytical method for determination of methylmercury level in water samples due to modify the Akagi method. Then, we were able to understand mercury behavior between mercury level in soil and soluble mercury level through this investigation by using a new method which was developed by us, and Akagi method. The results are as follows・In the case of a new analytical method of methymercury level about water samples, it is possible to analyze methymercury by using 200ml as sample.・In case of soils which were taken in Guiyun China, here is good correlation between total mercury level in soil and methymercury level in soil (r=0.89)・Basically, there is no correlation between soluble total mercury level in soil and soluble methylmercury.・Although, in the case of soluble total mercury, there is a little correlation between total mercury level in soil and soluble total mercury, however, completely, there is no correlation between methymercury level in soil and soluble methylmercury. Especially, the case of soluble methylmercury, it is thought to have a special behavior on solubility in soil.・As a result, there is good correlation between soluble methylmercury and EC(electronic conductivity) in soil(r=0.69)・The case of Methylation in soil, it is affected by soil species based on each soil characteristics. In present study, the highest methylmercury accumulation of soil is Kuroboku soil.・Supposing, each soil conditions are very stable, soil condition and mercury behavior in soil easily changed by adding an another environmrntal factors such as sun light, temperature so on
