  abstract = {{R}ice consumption is the primary pathway of methylmercury ({M}e{H}g) exposure for residents in mercury-mining areas of {G}uizhou {P}rovince, {C}hina. {I}n this study, compound-specific stable isotope analysis ({CSIA}) of {M}e{H}g was performed on rice samples collected in the {W}anshan mercury mining area. {A}n enrichment of 2.25in total {H}g ({TH}g) delta {H}g-202 was observed between rice and human hair, and {TH}g {D}elta {H}g-199 in hair was 0.12higher than the value in rice. {R}ice and human hair samples in this study show distinct {H}g isotope signatures compared to those of fish and human hair of fish consumers collected in {C}hina and other areas. {D}istinct {H}g isotope signatures were observed between {IH}g and {M}e{H}g in rice samples (in mean +/- standard deviation: delta {H}g-202({IH}g) at -2.30 +/- 0.49, {D}elta {H}g-199({IH}g) at -0.08 +/- 0.04, n = 7; delta {H}g-202({M}e{H}g) at -0.80 +/- 0.25, {D}elta {H}g-199({M}e{H}g) at 0.08 +/- 0.04, n = 7). {U}sing a binary mixing model, it is estimated that the atmospheric {H}g contributed 31% +/- 16% of {IH}g and 17% +/- 11% of {TH}g in the rice samples and the {IH}g in soil caused by past mining activities contributed to the remaining {H}g. {T}his study demonstrated that {H}g stable isotopes are good tracers of human {M}e{H}g exposure to fish and rice consumption, and the isotope data can be used for identifying the sources of {IH}g and {M}e{H}g in rice.},
