Mercury as a proxy for volcanic emissions in the geologic record

SE Grasby, TR Them II, Z Chen, R Yin… - Earth-Science …, 2019 - Elsevier
Large igneous province (LIP) eruptions are increasingly considered to have driven mass

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

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

JD Demers, JD Blum, DR Zak - Global Biogeochemical Cycles, 2013 - Wiley Online Library
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

JB Chen, H Hintelmann, XB Feng, B Dimock - … et Cosmochimica Acta, 2012 - Elsevier
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 …

Mercury cycling and isotopic fractionation in global forests
