摘　　要：对桂林青狮潭水库周边区域的土壤和常见蔬菜辣椒进行了汞污染调查。采集的样品包括58个土壤样和14个辣椒样。土壤样品包括29个岸土,7个公平镇垃圾土,22个菜地土壤。结果表明,由北向南,水库周边土壤总汞含量呈现出岸边自然土、垃圾土、菜地土依次增高的趋势。其中菜地土总汞含量均值为0.134 6μg/g,31号样点土壤总汞含量为0.445 3μg/g,超过了我国《土壤环境质量标准(GB 15618-2008)》第二级标准的最低限值(Hg≤0.2μg/g),表明水库南侧土壤已有一定程度的污染。辣椒果实平均总汞含量为0.008 2μg/g,没有超出国家相关标准限定值。The mercury pollution of soil and common vegetable-chili surrounding Qingshitan reservoir in Guilin city has been investigated.The results showed that the mercury content increased from north to south,from the shore natural soil to garbage soil,and to vegetable field soil.The average content of mercury in vegetable field soil was 0.134 6 μg/g.The total mercury content of NO.31 sample is 0.445 3 μg/g,higher than the highest allowable value （Hg≤0.2 μg/g）.According to《soil environment quality standard GB 15618-2008》 of China,It is indicated that there is a certain degree of pollution in the south soil of reservoir.The average mercury content of chili is 0.008 2 μg/g,not beyond the limit value of national standard.
