geometric standard deviation 1.80. For exposure to
B[a]P through dermal contact pathway, the potency
of 37.47 (mg kg1 day1
)
1 based on incidence of
skin tumors in mice (Schmahl et al., 1977) could be
used (Hussain et al., 1998). The cancer slope factors are
normalized to account for extrapolation to a different
body weight from standard of 70 kg.
