Mercury (Hg) is a global pollutant that emits in large quantities to the atmosphere (> 6,000–
8,000 Mg Hg per year) through anthropogenic activities, biomass burning, geogenic …

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

Methylmercury (MeHg) is a neurotoxin, mainly derived from microbial mercury methylation in
natural aquatic environments, and poses threats to human health. Polar regions and paddy …

Global climate change has led to profound alterations of the Arctic environment and
ecosystems, with potential secondary effects on mercury (Hg) within Arctic biota. This review …

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

Svalbard is an important study area for investigating the long-range transport of mercury
(Hg) and other trace elements to the Arctic. Few studies have focused on their …

Retrogressive thaw slumps (RTSs) are thermokarst features created by the rapid thaw of ice-
rich permafrost, and can mobilize vast quantities of sediments and solutes downstream …

Anthropogenic mercury (Hg) undergoes long-range transport to the Arctic where some of it is
transformed into methylmercury (MeHg), potentially leading to high exposure in some Arctic …

Abstract Mercury (Hg) in the Arctic Ocean is a concern due to unusually high concentrations
of monomethylmercury (MMHg) in fish and marine animals. Increased human exposure from …

Permafrost thaw ponds are ubiquitous in the eastern Canadian Arctic, yet little information
exists on their potential as sources of methylmercury (MeHg) to freshwaters. They are …
