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

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 …

Anthropogenic activities have led to large-scale mercury (Hg) pollution in the Arctic,,,,,. It has
been suggested that sea-salt-induced chemical cycling of Hg (through 'atmospheric mercury …

Virtually all biotic, dark abiotic, and photochemical transformations of mercury (Hg) produce
Hg isotope fractionation, which can be either mass dependent (MDF) or mass independent …

Global models of atmospheric mercury generally assume that gas-phase OH and ozone are
the main oxidants converting Hg 0 to Hg II and thus driving mercury deposition to …

Snow in the environment acts as a host to rich chemistry and provides a matrix for physical
exchange of contaminants within the ecosystem. The goal of this review is to summarise the …

It was discovered in 1995 that, during the spring time, unexpectedly low concentrations of
gaseous elemental mercury (GEM) occurred in the Arctic air. This was surprising for a …

Global anthropogenic and legacy mercury (Hg) emissions are the main sources of Arctic Hg
contamination, primarily transported there via the atmosphere. This review summarizes the …

After polar sunrise in the Arctic, sunlight-induced reactions convert gaseous elemental
mercury into compounds that are rapidly deposited to the snowpack. These atmospheric …

A rigorous synthesis of the sea-ice ecosystem and linked ecosystem services highlights that
the sea-ice ecosystem supports all 4 ecosystem service categories, that sea-ice ecosystems …
