| 摘 要： | 汞污染一直是全球备受关注的问题，由于土壤是环境汞的源和汇，因此已经开展了大量相关的研究工作。本论文系统总结了土壤环境汞形态及吸附解吸特征的研究现状，综述了不同类型土壤汞的背景含量，以及汞在土壤中的赋存形态，分析了土壤汞吸附特征及几种典型的土壤吸附剂（粘土矿物、铁锰氧化物、硫化物和土壤有机质）对汞吸附的作用机制。

| Abstract: | Mercury pollution has been a global issue for a long time. A lot of mercury researches have been done for soil because it is both a source and sink of mercury. This paper summarized the research status of speciation and adsorption-desorption characteristics of soil mercury, described the background levels and speeiation of mercury in different type of soil, and analyzed the adsorption characteristics and adsorption mechanism of some soil adsorbents on mercury adsorption, including clay minerals, iron and manganese oxides, sulfides and soil organic matter. |
