Carmona-Garcia J, Saiz-Lopez A, Mahajan A, Wang F, Borrego-Sanchez A, Acuna A, et al.
Proc Natl Acad Sci U S A
. 2025 Mar;
122(10):e2422885122.
PMID: 40030012
In the polar regions, which are vulnerable receptors of mercury pollution, atmospheric mercury depletion events (AMDEs) efficiently convert elemental mercury (Hg(0)) into oxidized mercury (Hg(II)) via bromine oxidation. Hg(II) subsequently...

PMID: 31117649
The efficient gas-phase photoreduction of Hg(II) has recently been shown to change mercury cycling significantly in the atmosphere and its deposition to the Earth's surface. However, the photolysis of key...

PMID: 30442890
Anthropogenic mercury (Hg(0)) emissions oxidize to gaseous Hg(II) compounds, before deposition to Earth surface ecosystems. Atmospheric reduction of Hg(II) competes with deposition, thereby modifying the magnitude and pattern of Hg...
