The results of fitting the linear multistage model to this data set to arrive at cancer potency estimates are shown in Table 2. Similar analyses from different sources
are also shown. The State of California (CARB,1987) extensively reviewed the available literature in their derivation of the cancer potency value of 0.29 (mg/
kg/day)1 [recently updated to 0.31 (mg/kg/day)1].
