Dramatic environmental shifts are occuring throughout the Arctic from climate change, with
consequences for the cycling of mercury (Hg). This review summarizes the latest science on …

The atmosphere is the major transport pathway for distribution of mercury (Hg) globally.
Gaseous elemental mercury (GEM, hereafter Hg 0) is the predominant form in both …

During Arctic springtime, halogen radicals oxidize atmospheric elemental mercury (Hg0),
which deposits to the cryosphere. This is followed by a summertime atmospheric Hg0 peak …

Net photoreduction of divalent mercury (Hg (II)) and volatilization of photoreduction products
(ie, elemental mercury (Hg (0))/dissolved gaseous mercury (DGM)) is a mechanism by which …

Sea ice (including overlying snow) is a dynamic interface between the atmosphere and the
ocean, influencing the mercury (Hg) cycling in polar oceans. However, a large-scale and …

Mercury (Hg) isotope exchange is a common process in biogeochemical transformations of
Hg in the environment, but it is unclear whether and at what rates dissolved elemental Hg (0) …

Daytime volatilization of gaseous elemental mercury (Hg (0) aq) is a significant mechanism
for mercury removal from aquatic systems and potentially limits the production and …

Near-surface mercury and ozone depletion events occur in the lowest part of the
atmosphere during Arctic spring. Mercury depletion is the first step in a process that …

Mercurous Hg [Hg (I)] is, from the perspective of chemistry, an inevitable intermediate in Hg
(II)/Hg (0) redox, presumably playing a critical role in the environmental transformation of …

Detection of highly toxic mercury ions (Hg 2+) in actual environmental and biological
samples is of significant importance for protecting environment and human health. In this …
