Comparison of the estimated mean dietary exposure with or without mapping to previously established PTWIs by the Committee of the FAO/WHO JECFA (µg/kg body weight/week)

¹⁾PTWIs for total mercury and lead were withdrawn by the WHO/FAO JECFA in 2010.

²⁾Weekly intake is calculated by multiplying daily mean intake by 7 and then dividing by the average body weight of 56.35 kg in 2008 and 54.15 kg in 2009, respectively, which were derived from the corresponding KNHANES.

³⁾Food items in the representative food list were used in mapping all other foods in order to procure contaminant levels when estimating total dietary exposure to heavy metals from all foods.
