| 摘 要： | 为了解十涧湖中汞的污染状况，分别对冬夏两季水体中不同形态汞的含量及底泥中总汞含量进行测定，分析了水体中不同形态汞的季节变化，进行了水体中汞污染的单因子评价及底泥中汞的潜在生态风险评价，结果表明，夏季，颗粒态汞是水体中汞的主要存在形态，占总汞的56．9％；冬季，溶解态汞是水体中汞的主要存在形态，占总汞的59．82％；夏季，除水中颗粒态汞比冬季有所增加外，总汞、溶解态汞及活性汞的浓度均比冬季有所降低；冬夏两季水体中汞的污染指数Ii分别为0．921、0．765，均是潜在危害元素，但冬季水体中汞接近已造成危害的元素；底泥中汞的生态危害系数Er^i=11．76〈40，危害等级为I级，属于轻微的生态危害。

| Abstract: | In order to know the mercury pollution status of Shijian Lake,different form mercury contents in water and total content in sediment in winter and summer were determined respectively.The seasonal variation of different forms mercury in water was analyzed,and single-factor evaluation of mercury pollution in water and potential ecological risk index of mercury in sediment were carried out.The results showed that in summer,particulate mercury is the main form of mercury in water,accounted for 56.90%;in winter,... |
