摘要
为探明清水江水、鱼体和悬浮物中的汞污染情况,采用地质累积指数、单因子污染指数和潜在生态风险因子对清水江悬浮物进行了汞污染评价以及汞残留指数对清水江鱼体汞进行了污染评价。结果表明,清水江旁海段悬浮物汞污染程度高于清水江下司段,并已达到了重度潜在生态危害水平。然而,清水江水和鱼体未受到汞的污染,分析认为磷化工尾矿可能是加剧清水江悬浮物汞污染的原因之一。
To explore mercury pollution in water,fishes and suspended particles of Qingshui river,the level of mercury pollution in the suspended particles of Qingshui river is evaluated with geoaccumulation index（ Igeo）,single factor contaminant index（ Cif） and potential ecological risk factor（ Eir）. In addition,the level of mercury pollution in the fishes of Qingshui river is evaluated with mercury residual index（ I）. The results show that suspended particles in Panghai section of Qingshui river are subject to more mercury pollution than that in Xiasi section of Qingshui river,and the degree of mercury pollution has reached the severe potential ecological hazard level. However,water and fish body of Qingshui river were not contaminated by mercury. Our analysis believes that tailings of phosphorus chemical industry may be one reason of increasing mercury polltion in suspended particles of Qingshui river.
