In this article, my goal is to present you with some simple Eh-pH diagrams for Hg that you can use for your work (just refer to coalgeology.com). I though about providing some useful facts related to mercury in United States and other places of the world, including various news sources.

The Eh-pH diagrams I am presenting are prepared with “Geochemist’s Workbench”. Eh -pH diagrams depends on the concentration of main species (in our case dissolved mercury) and other dissolves species in association. There are three Eh-pH diagrams prepared using Geochemist’s Workbench. In all of them I have used Mercury activity = 10^-10. First diagram is prepared with only Hg, second one with 10 ppm of SO4, third one with another additional 50 ppm of chloride.
