Observational and modeling constraints on global anthropogenic enrichment of mercury

HM Amos, JE Sonke, D Obrist, N Robins… - … science & technology, 2015 - ACS Publications
Centuries of anthropogenic releases have resulted in a global legacy of mercury (Hg)

A new mechanism for atmospheric mercury redox chemistry: implications for the global mercury budget

HM Horowitz, DJ Jacob, Y Zhang… - Atmospheric …, 2017 - acp.copernicus.org
Mercury (Hg) is emitted to the atmosphere mainly as volatile elemental Hg 0. Oxidation to
water-soluble Hg II plays a major role in Hg deposition to ecosystems. Here, we implement a …

Contrasting effects of marine and terrestrially derived dissolved organic matter on mercury speciation and bioavailability in seawater

AT Schartup, U Ndu, PH Balcom… - … science & technology, 2015 - ACS Publications
Methylmercury (MeHg) is the only species of mercury (Hg) to biomagnify in aquatic food-
webs to levels that are a widespread concern for human and ecological health. Here we …

Biogeochemical drivers of the fate of riverine mercury discharged to the global and Arctic oceans

Y Zhang, DJ Jacob, S Dutkiewicz… - Global …, 2015 - Wiley Online Library
Rivers discharge 28±13 Mmol yr− 1 of mercury (Hg) to ocean margins, an amount
comparable to atmospheric deposition to the global oceans. Most of the Hg discharged by …

Top-down constraints on atmospheric mercury emissions and implications for global biogeochemical cycling

S Song, NE Selin, AL Soerensen… - Atmospheric …, 2015 - acp.copernicus.org
We perform global-scale inverse modeling to constrain present-day atmospheric mercury
emissions and relevant physiochemical parameters in the GEOS-Chem chemical transport …

Photomicrobial visible light-induced magnetic mass independent fractionation of mercury in a marine microalga

K Kritee, LC Motta, JD Blum, MTK Tsui… - ACS Earth and Space …, 2017 - ACS Publications
Methylmercury (MeHg), a highly neurotoxic substance, accumulates in aquatic food webs,
and is enriched in odd isotopes (ie, 199Hg and 201Hg), purportedly as a result of abiotic …

Recent advances in understanding and measurement of Hg in the environment: Surface-atmosphere exchange of gaseous elemental mercury (Hg0)

J Sommar, S Osterwalder, W Zhu - Science of the Total Environment, 2020 - Elsevier
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 …

The impact of sea ice on the air-sea exchange of mercury in the Arctic Ocean

BP DiMento, RP Mason, S Brooks, C Moore - Deep Sea Research Part I …, 2019 - Elsevier
Atmospheric deposition is the main input of mercury (Hg) to the ocean, even in remote
locations such as the Arctic. Furthermore, evasion of elemental Hg (Hg°) is the major sink for …

AL Soerensen, AT Schartup, E Gustafsson… - Environmental …, 2016 - ACS Publications
Eutrophication is expanding worldwide, but its implication for production and
bioaccumulation of neurotoxic monomethylmercury (MeHg) is unknown. We developed a …
