Percentage of estimated THg intake (A) and MeHg intake (B) from different media for the adult populations in Guizhou. Abbreviations: LG, Leigong; QZ, Qingzhen; WN, Weining; WS, Wanshan.

Calculated PDI (mean ± SD) of THg (A) and MeHg (B) for the adult population in Guizhou (primarily rice-based diet) and for adults in Japan, Norway, and the United States who ate a more fish-based diet. The data for Japan are from a population of rural, coastal women (); the Norwegian data are from a reference group of the general population (); and the U.S. data are from women in the general population (; ). The black dashed line represents the PTWI of 0.23 μg/kg/day recommended by , and the red dotted line indicates the U.S. EPA RfD of 0.10 μg/kg/day (). In (A) and (B), the red circles represent the maximum value; open circles (A) and blue circles (B) represent values for individuals in the Wanshan area.
