Forests mediate the biogeochemical cycling of mercury (Hg) between the atmosphere and
terrestrial ecosystems; however, there remain many gaps in our understanding of these …

Abstract The Minamata Convention on Mercury (MC) includes provisions for a global
monitoring program (GMP) and effectiveness evaluation (EE) to provide information on …

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 …

Since the early 1950s, the number of international measurement standards for anchoring
stable isotope delta scales has mushroomed from 3 to more than 30, expanding to more …

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

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

Once released into the atmosphere, mercury (Hg) is subject to long-range transport and a
series of physico-chemical reactions before reentering terrestrial ecosystems. Though …

Forest biomass and soils represent some of the largest reservoirs of actively cycling mercury
(Hg) on Earth, but many uncertainties exist regarding the source and fate of Hg in forest …

This review summarizes biogeochemical processes that operate on diel, or 24-h, time scales
in streams and the changes in aqueous chemistry that are associated with these processes …

Atmospheric deposition is a primary pathway by which mercury (Hg) enters terrestrial and
aquatic ecosystems; however, the chemical and meteorological processes that Hg …
