英文摘要	Mercury (Hg) release and migration from municipal solid waste landfills has been an important issue to nearby ecosystems and human health. To completely understand the Hg biogeochemical cycle in landfills, this review presents the Hg emission processes via different pathways, related controlling mechanisms, and critical Hg transport and transformation processes involving the diffusion and advection of Hg, Hg volatilization, Hg adsorption and desorption, Hg redox reactions, and Hg methylation and demethylation. These critical physical, chemical, and biological processes result in the phase transfer of Hg and the distribution of different Hg species in landfill gas (LFG), leachates, and cover soils. In addition, key factors (e.g., LFG, meteorological conditions, cover soils, and vegetation) affecting Hg emission processes and their impacts are discussed here. This work provides a comprehensive picture of Hg behavior in landfills, and has positive implications for the development of a process-based model and the control of Hg emissions from landfills. © 2020, Springer Nature Switzerland AG.
