Percentage of participants within each tertile of fish consumption that exceed established H-THg reference levels in μg/g in ASGM affected (left three bars) and Non-ASGM affected (right three bars) areas. Reference values indicated include the US National Research Council’s reference value for non-fish eating populations of 1.2 μg/g corresponding to a reference dose (RfD) for methylmercury of 0.1 μg/kg bodyweight/day (NRC (National Research Council), 2000); the WHO JEFCA PTWI 1.6 μg/ kg bodyweight established in 2003 and confirmed in 2006 which Peru adheres to, corresponding to 2.2 μg/g in hair (Joint FAO/WHO Expert Committee on Food Additives, 2006), and 10 μg/g which WHO previously established as the level of concern for impact of methylmercury on the developing fetus of pregnant mothers (World Health Organization (WHO), 1990), and which is commonly used as a reference level in the Amazon (Barbieri and Gardon, 2009).
