对广西珊瑚钨锡矿周边尾砂厂、废石厂和居民区土壤、植被进行采样分析，采集珊瑚矿周边尾砂厂、废石厂和居民区采集土壤样271620个，尾砂厂采植物样27个。采用原子荧光测汞仪进行分析测定法，研究土壤和茅草的不同部分中的汞含量。分析表明，距离矿区近的土壤汞含量高于距离矿区远的；土壤汞含量居民区大于尾砂场大于废石场。其中有65．0％的居民区、7．4％的尾砂场和6．3％废石场的样汞含量超过了我国《土壤环境质量标准（ GB 156182008）》第二级标准的最低限值（汞≤0．2μg／g）。
對廣西珊瑚鎢錫礦週邊尾砂廠、廢石廠和居民區土壤、植被進行採樣分析，採集珊瑚礦週邊尾砂廠、廢石廠和居民區採集土壤樣271620箇，尾砂廠採植物樣27箇。採用原子熒光測汞儀進行分析測定法，研究土壤和茅草的不同部分中的汞含量。分析錶明，距離礦區近的土壤汞含量高于距離礦區遠的；土壤汞含量居民區大于尾砂場大于廢石場。其中有65．0％的居民區、7．4％的尾砂場和6．3％廢石場的樣汞含量超過瞭我國《土壤環境質量標準（ GB 156182008）》第二級標準的最低限值（汞≤0．2μg／g）。

Soils and plants in tailings factories , waste rock site and residential areas in Shanhu tungsten tin deposit in Guangxi province have been sampled and analyzed .Collecting 271620 soil samples from tailings factories , waste rock sites and residents area in surrounding areas of Shanhu deposit , 27 plants samples from tailings factory , by u-sing atomic fluorescence analysis method , mercury contents in different parts of the soil and grass have been deter-mined .It is showed that the mercury contents of soil near the mining are higher than the contents in far mining area . Mercury content in soil in residents is higher than in tailings field , while the mercury content in tailings field is higher than in waste rock field .Mercury contents in 65.0%of residents area , 7.4%tailings field and 6.3%in spoil ground can exceed the second grade standard of minimum value ( mercury content is less than or equal to 0.2μg/g) of "soil environmental quality standard ( GB 15618 2008 ) .
