Mercury (Hg) is a global atmospheric pollutant. In its oxidized form (Hg II), it can readily
deposit to ecosystems, where it may bioaccumulate and cause severe health effects. High …

Human exposure to toxic mercury (Hg) is dominated by the consumption of seafood 1, 2.
Earth system models suggest that Hg in marine ecosystems is supplied by atmospheric wet …

Stable mercury (Hg) isotope ratios are an emerging tracer for biogeochemical
transformations in environmental systems, but their application requires knowledge of …

Foliage uptake of atmospheric elemental mercury (Hg0) and subsequent translocation by
the phloem is the main pathway for Hg accumulation in tree rings. Tree rings have been …

Peatland vegetation takes up mercury (Hg) from the atmosphere, typically contributing to net
production and export of neurotoxic methyl-Hg to downstream ecosystems. Chemical …

In this study, exchange fluxes and Hg isotope fractionation during water–atmosphere Hg (0)
exchange were investigated at three lakes in China. Water–atmosphere exchange was …

During Arctic springtime, halogen radicals oxidize atmospheric elemental mercury (Hg0),
which deposits to the cryosphere. This is followed by a summertime atmospheric Hg0 peak …

Nature archives record atmospheric mercury (Hg) depositions from directly emitted Hg and
re-emitted legacy Hg. Tracing the legacy versus newly deposited Hg is still, however …

Deposition of atmospheric mercury (Hg) is the most important Hg source on the high-altitude
Himalayas and Tibetan Plateau. Herein, total gaseous Hg (TGM) at an urban and a forest …

The origin of methylmercury in pelagic fish remains unclear, with many unanswered
questions regarding the production and degradation of this neurotoxin in the water column …
