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

The atmosphere is a key component of the biogeochemical cycle of mercury, acting as a
reservoir, transport mechanism, and facilitator of chemical reactions. The chemical and …

Mercury (Hg) researchers have made progress in understanding atmospheric Hg, especially
with respect to oxidized Hg (HgII) that can represent 2 to 20% of Hg in the atmosphere …

Mercury (Hg) is a global health concern due to its toxicity and ubiquitous presence in the
environment. Here we review current methods for measuring the forms of Hg in the …

Long-range transport and residence time of elemental Hg (Hg°) in air promote global
dispersion and deposition in remote ecosystems. Many biotic and abiotic factors contribute …

Mercury (Hg), a global contaminant, is emitted mainly in its elemental form Hg0 to the
atmosphere where it is oxidized to reactive HgII compounds, which efficiently deposit to …

Despite 30 years of study, gaseous elemental mercury (Hg0) exchange magnitude and
controls between terrestrial surfaces and the atmosphere still remain uncertain. We …

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

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

The Zeppelin Observatory (78.90° N, 11.88° E) is located on the Zeppelin Mountain at 472 m
above sea level on Spitsbergen, the largest island of the Svalbard archipelago. Established …
