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

Metal stable isotope signatures as tracers in environmental geochemistry
JG Wiederhold - Environmental science & technology, 2015 - ACS Publications
The biogeochemical cycling of metals in natural systems is often accompanied by stable
isotope fractionation which can now be measured due to recent analytical advances. In …

Mercury isotopes in a forested ecosystem: Implications for air‐surface exchange dynamics and the global mercury cycle
Forests mediate the biogeochemical cycling of mercury (Hg) between the atmosphere and
terrestrial ecosystems; however, there remain many gaps in our understanding of these …

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

Mercury deposition and redox transformation processes in peatland constrained by mercury stable isotopes
Peatland vegetation takes up mercury (Hg) from the atmosphere, typically contributing to net
production and export of neurotoxic methyl-Hg to downstream ecosystems. Chemical …

Unusual fractionation of both odd and even mercury isotopes in precipitation from Peterborough, ON, Canada
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 …
