NA—not applicable. a For an x % occurrence of health effect, BMDLx is the lower one-sided confidence limit of the benchmark dose (BMD). b Inhalation exposure was used as the original endpoint. Route-to-route extrapolation was used to calculate the BMDL for oral exposure [69]. c The no effect level (NOEL), no observed adverse effect level (NOAEL), or lowest observed adverse effect level (LOAEL) were utilized because no appropriate BMD modeling for exposure through the mouth has been documented. d Overall exposure to lead is determined in blood, and the figures are based on that. The BMDL that was employed was determined based on dietary exposure [29]. e Renal tubular hyperplasia, rather than renal tubule adenoma or cancer, was a more sensitive endpoint. f This was a conservative minimal concentration based on the literature’s BMDL10 range of “about 3–29 mg/kg bw/day” for safrole [91].
