- Although a global health-hazard, the mechanism of mercury-methylation remains unknown. Building on seven interdisciplinary publications during this REF-period, which investigated the effects of different environmental variables: e.g. cell-surface ligands (doi.org/10.1016/j.chemgeo.2017.02.015) and natural-organic-matter (https://doi.org/10.1016/j.gca.2014.11.018), this paper challenges the conventional paradigm and presents a mechanistic model for the transfer of mercury into the cell-cytoplasm, a rate-limiting factor for mercury-methylation. In addition, this paper established the first use of High Energy Resolution Fluorescence Detection for mercury in the UK which allowed ultra-low concentration (50 nM) measurements, simulating real biological conditions and providing far more information than conventional XANES or EXAFS.
