Anthropogenic mercury (Hg) emissions have driven marked increases in Arctic Hg levels,
which are now being impacted by regional warming, with uncertain ecological …

We review recent progress in our understanding of the global cycling of mercury (Hg),
including best estimates of Hg concentrations and pool sizes in major environmental …

Mercury (Hg) is emitted to the atmosphere mainly as volatile elemental Hg 0. Oxidation to
water-soluble Hg II plays a major role in Hg deposition to ecosystems. Here, we implement a …

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 …

Mercury is a fascinating fluid metal that exists as liquid at 25 C (0 C= 273 K). This silver
colored d-block heavy metal exhibits noble-gas-like characteristics and solidifies at a …

Observations of elemental mercury (Hg0) at sites in North America and Europe show large
decreases (∼ 1–2% y− 1) from 1990 to present. Observations in background northern …

In the past 40 years, atmospheric chemists have come to realize that halogens exert a
powerful influence on the chemical composition of the troposphere and through that …

Elevated biological concentrations of methylmercury (MeHg), a bioaccumulative neurotoxin,
are observed throughout the Arctic Ocean, but major sources and degradation pathways in …

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

The Arctic region forms a unique environment with specific physical, chemical, and
biological processes affecting mercury (Hg) cycles and limited anthropogenic Hg sources …
