The estimated daily intake (EDI) of the five heavy metals was calculated by the following equation (Pappalardo et al., 2017): EDI = MS x C BW where MS and C represent the meal size corresponding to a whole packaged canned tuna (MS = 120 g) and the heavy metal concentrations (μg/kg), separately. BW is the average body weight (70 …
