Environmental context Mercury, in its methylated form, is a neurotoxin that biomagnifies in
marine and terrestrial foodwebs leading to elevated levels in fish and fish-eating mammals …

The atmosphere is the major transport pathway for distribution of mercury (Hg) globally.
Gaseous elemental mercury (GEM, hereafter Hg 0) is the predominant form in both …

Long-term monitoring of data of ambient mercury (Hg) on a global scale to assess its
emission, transport, atmospheric chemistry, and deposition processes is vital to …

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 …

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 …

We present here the first mercury speciation study in the water column of the Southern
Ocean, using a high-resolution south-to-north section (27 stations from 65.50° S to 44.00° S) …

Mercury (Hg) is a ubiquitous metal in the ocean that undergoes in situ chemical
transformations in seawater and marine sediment. Most relevant to public health is the …

We develop an improved treatment of the surface ocean in the GEOS-Chem global 3-D
biogeochemical model for mercury (Hg). We replace the globally uniform subsurface ocean …

Our knowledge of the distribution of mercury concentrations in air of the Southern
Hemisphere was until recently based mostly on intermittent measurements made during …

We perform global-scale inverse modeling to constrain present-day atmospheric mercury
emissions and relevant physiochemical parameters in the GEOS-Chem chemical transport …
