A high-exposure scenario was chosen to describe the intake of selected toxicants by infants through breast milk in the context of risk assessment. For calculations of a hypothetical upper bound intake (hUBI), an average consumption of 1,000 mL per day breast milk and a body weight (bw) of 6 kg were assumed. Toxicants that were detected below the LOQ were estimated at the LOQ level, while the highest detected concentration was assumed for quantitated exposures. Tolerable daily intake (TDI) or acceptable daily intake (ADI) values for adults were adapted from the most current guidelines of the European Food Safety Authority (EFSA). For infants below 16 weeks of age, these recommendations were corrected by a factor of one third the TDI/ADI according to a general EFSA recommendation . 0.018 3889 Riddelliin-N-oxide 0.021 BMDL10: 70 0.0035 20000 Scopolamine 0.0004 0.016 0.0053 0.000067 79 Food processing by-products PhIP 0.042 BMDL10: 480 0.0070 68571
