以前我们显示，在清镇地区采集的土壤样本的平均汞浓度高达对照地区的150倍(Yasuda等人，2004年)。此外，松山等人(2004年)报告了每个土壤样本中甲基汞和总汞水平之间的良好相关性(r=0.89)，尽管不同样本之间的浓度差异很大(fi)。稳定的甲基/总汞比值可能是由于土壤中汞的甲基化和去甲基化之间的平衡状态。为了准确估计汞，特别是甲基汞的淋溶部分的危险程度，还必须考虑降雨或fl污染的影响，因为甲基汞比无机汞对人体健康的危害更大。在这里，我们对土壤样本中的甲基汞进行了淋溶测试，以进一步详细确定清镇地区的汞污染水平。
Previously We showed that average mercury concentrations of soil samples collected in the Qingzhen area were as high as 150 times those of the control area (Yasuda et al., 2004). Moreover, Matsuyama et al.(2004) reported a good correlation (r= 0.89) between methylmercury and total mercury levels in each soil sample, despite the fact that the concentrations varied significantly among the samples. The stable methyl/total mercury ratios were probably due to a state of the development of equilibrium between mercury methylation and demethylation in the soil.To accurately the estimate hazardousness level of the leaching portion of mercury, particularly methylmercury, the impact of rainfall or flooding must also be considered, since methylmercury is more hazardous to human health than inorganic mercury. Here, we conducted leaching tests of methylmercury from the soil samples to determine in further detail the level of mercury pollution in the Qingzhen area.'
