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 …

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 …

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

An assessment of current and future emissions, air concentrations, and atmospheric
deposition of mercury worldwide is presented on the basis of results obtained during the …

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 …

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

We present a new chemical mechanism for Hg0/HgI/HgII atmospheric cycling, including
recent laboratory and computational data, and implement it in the GEOS-Chem global …

The current knowledge concerning mercury dry deposition is reviewed, including dry-
deposition algorithms used in chemical transport models (CTMs) and at monitoring sites and …
