| 摘 要： | 为了解万峰湖周边土壤中汞污染现状和环境风险,对13个不同位置土壤中汞含量进行了测定分析,并用地累积指数法和潜在生态危害指数法综合研究和评估了土壤中总汞的污染水平和生态风险。结果显示,13个采样点土壤中汞含量差异较小,土壤汞含量为0.004~0.618mg·kg-1,平均含量为0.141mg·kg-1,仅三江口和吉隆土壤汞含量超过贵州土壤汞背景值。地累积指数法和潜在生态危害指数法显示万峰湖周边土壤总体无汞污染,潜在生态风险很低。

| Abstract: | In order to realize the pollution status and environmental risk of soil mercury around the Wan?feng Lake,this thesis measures and analyzes the content of soil mercury located in 13 different positions. The geo-accumulation index method and the potential ecological risk index were used to research and eval?uate comprehensively the pollution levels and ecological risk of the mercury in soil.The results showed that there were little difference among the contents of soil mercury,ranged from 0.004~0.618mg · kg-1,in the soil of 13 sampling points,and the average content was 0.141mg·kg-1.However,only the contents of soil mer?cury in San Jiangkou and Ji Long exceed its background value of Guizhou.Therefore,the geo-accumulation index method and the potential ecological risk index method showed that there is no mercury pollution in soil around the WanFeng Lake,and its potential risk is much lower. |
