摘要
以汾河典型断面下河床土壤中的汞为研究对象，通过实地测量和实验室土柱实验模拟，对汾河沿岸汞的来源和分布状况进行了研究分析。研究结果表明：重金属汞多集中在土壤的表层40～100cm之间；表层土壤汞的主要来源于人为源中的污水灌溉，且汞的污染范围多在距两岸150m的范围内；汾河深层土壤汞污染主要为长时间河槽向两岸滩地的迁移积累。文末针对汾河沿岸的汞污染现状提出了相应的修复方案。
The mercury content of riverbed soil in the representative emblematic section of Fenhe river basin was investigated via the field measurements and laboratory column experi- ments. The main source and distribution regularity of mercury were searched and analyzed. The obtained results show that the heavy metal mercury is typically found in topsoil between 40 cm and 100 cm, which comes mainly from the anthropogenic sewage irrigation and contaminates the topsoil within the range of 150 m away from the river. The mercury in the deeper soil is mainly derived from the long-term migration from the river channel into floodplain. Finally, the situation of mercury pollution in the Fenhe river basin was summarized and the corresponding treatment countermeasures were put forward.
