Abstract

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.
