The B3 brand, the origin of the highest trace elements exposure, was chosen for the margin of exposure calculations. * Values of median and percentiles are expressed in µg/kg bw/day. a Pb margin of exposure calculated with BMDL0.1 = 0.5 µg/kg bw/day based on neurotoxic effect [41]. b As margin of exposure calculated with BMDL0.1 = 0.3 µg/kg bw/day for MOE 1 and BMDL0.1 = 8 µg/kg bw/day for MOE 2 [16].
