摘　　要：汞是高毒性的全球污染物,其氧化还原转化是控制汞全球迁移与生物累积的关键过程。理论上,汞的氧化还原多为单电子转移,一价汞(Hg(Ⅰ))是重要中间体。作为亚稳态汞,Hg(Ⅰ)易受前处理或分析方法的影响发生转化,难以被直接检测,其环境赋存及其在汞氧化还原循环中的作用认知尚属空白。Mercury(Hg)is a global pollutant.The redox transformation of Hg plays a pivotal role in the Hg global cycle,with mercurous mercury(Hg(Ⅰ))serving as an important intermediate theoretically.Due to the metastable nature of Hg(Ⅰ),it was considered unstable and susceptible to dispropor-tionation.This finding not only challenged the traditional viewpoint that Hg(Ⅰ)cannot exist in wa-ter,but also revealed that the stability of Hg(Ⅰ)had a significant effect on the reduction process of Hg(Ⅱ)in the natural water.
