  abstract = {{E}xposure of humans and wildlife to various inorganic and organometallic forms of mercury ({H}g) may induce adverse health effects. {W}hile human populations in developed countries are mainly exposed to marine fish monomethylmercury ({MMH}g), this is not necessarily the case for developing countries and diverse indigenous people. {I}dentification of {H}g exposure sources from biomonitor media such as urine or hair would be useful in combating exposure. {H}ere we report on the {H}g stable isotope signatures and {H}g speciation in human hair across different gold miner, indigenous and urban populations in {B}olivia and {F}rance. {W}e found evidence for both mass-dependent isotope fractionation ({MDF}) and mass-independent isotope fractionation ({MIF}) in all hair samples. {T}hree limiting cases of dominant exposure to inorganic {H}g ({IH}g), freshwater fish {MMH}g, and marine fish {MMH}g sources are used to define approximate {H}g isotope source signatures. {K}nowing the source signatures, we then estimated {H}g exposure sources for the {B}olivian gold miner populations. {M}odeled {IH}g levels in hair correspond well to measured {IH}g concentrations ({R} = 0.9), demonstrating that {IH}g exposure sources to gold miners can be monitored in hair samples following either its chemical speciation or isotopic composition. {D}ifferent {MMH}g and inorganic exposure levels among gold miners appear to correspond to living and working conditions, including proximity to small towns, and artisanal vs large scale mining activity.},
