材料和方法用于分析的土壤样品取自清镇市的高污染区，如先前的研究所定义的（Yasuda等，2004;松山等人，2004年）。根据先前的研究进行取样（Yasuda等人，2004年），同时将网格宽度从100米x 100米改为50米x 50米，以获得86个土壤样本（图1）。用手清除小石块和小植物根系后，用四分之一法混合土样，得到均质土样。在测量水分含量后，在不干燥的情况下分析样品的汞浓度及其化学形式。采用冷原子吸收法测定总汞浓度
MATERIALS AND METHODSThe soil samples for analysis were taken from the highly contaminated area in Qingzhen as is defined by the previous study (Yasuda et a1., 2004; Matsuyama et al., 2004). Sampling was done in accordance with the previous study (Yasuda et a1., 2004), while changing the mesh width from 100 mx 100 m to 50 m x 50 m to obtain 86 soil samples (Figure 1). After removing small stones and small plant roots by hand, soil sample was mixed by the quarter method to obtain homogeneous soil samples. After measuring the moisture content, the samples were analyzed for mercury concentration and its chemical form without drying. The total mercury concentration was determined by cold vapor atomic absorption
