摘　　要：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271 620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(GB15618-2008)》第二级标准的最低限值(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 ） .
