Anomalous fractionation of mercury isotopes in the Late Archean atmosphere [PDF]
Nature Communications, 2020 Earth’s surface underwent a dramatic transition ~2.3 billion years ago when atmospheric oxygen first accumulated during the Great Oxidation Event. Here, the authors find that biogenic methane and volcanic emissions played a vital role in the reduced Late

The Athabasca River regulates methylmercury burdens of waterbirds breeding downstream [PDF]
Scientific ReportsThis study characterized the transport pathways and sources of mercury in downstream food webs of the Athabasca River Basin in northern Alberta, Canada. Flowing through a large boreal watershed in the Athabasca Oil Sands Region, the river drains into the

Mercury Isotopes as Proxies to Identify Sources and Environmental Impacts of Mercury in Sphalerites. [PDF]
Sci Rep, 2016 AbstractDuring the past few years, evidence of mass independent fractionation (MIF) for mercury (Hg) isotopes have been reported in the Earth’s surface reservoirs, mainly assumed to be formed during photochemical processes. However, the magnitude of Hg-MIF in interior pools of the crust is largely unknown.

The Global Observation System for Mercury dataset for mercury stable isotope signatures in environmental media [PDF]
Scientific DataThe natural variability in the abundance ratios of stable isotopes of mercury (Hg), which collectively forms its isotopic composition, provides information on Hg sources and biogeochemical pathways. Modern mass spectrometry has allowed for measurement of

Warming-induced retreat of West Antarctic glaciers weakened carbon sequestration ability but increased mercury enrichment [PDF]
Nature CommunicationsThe Southern Ocean, one of Earth’s most productive areas, is widely recognized as a major sink for atmospheric carbon and mercury, tightly coupling primary production with the sedimentary sequestration of these elements. The impacts of climate warming on

Quantitative dual-isotope preclinical SPECT/CT imaging and biodistribution of the mercury-197m/g theranostic pair with [197m/gHg]HgCl2 and a [197m/gHg]Hg-tetrathiol complex as a platform for radiopharmaceutical development [PDF]
EJNMMI Radiopharmacy and ChemistryBackground Mercury-197m (197mHg, t1/2 = 23.8 h) and mercury-197g (197gHg, t1/2 = 64.14 h) possess favorable nuclear properties for imaging and targeted therapy, but the development of suitable chelators for mercury-based radiopharmaceuticals remains ...
