Brief Summary:
Evaluation of the pharmacokinetics for \[14C\]-benzo\[a\]pyrene (\[14C\]-BaP) and metabolites in plasma and urine over 48 hours following a 50 ng dose (5.4 nCi) alone or with 1250 ng phenanthrene.
Detailed Description:
The pharmacokinetics for \[14C\]-BaP and metabolites will be assessed by UHLPC-Accelerator Mass Spectrometry (AMS, Lawrence Livermore National Laboratory) in plasma and urine collected over 48 hours following oral doses of 50 ng dose (5.4 nCi) alone or with 1250 ng phenanthrene. Metabolite profiles and kinetics of elimination are predicted to be consistent with a BaP physiologically based pharmacokinetic (PBPK) model developed by Pacific Northwest National Laboratory (PNNL). A non-smoker, not exposed occupationally, receives 270-700 ng of BaP daily; about 95% dietary. The WHO has set an estimated safe daily lifetime (70 year/70 Kg individual, cancer endpoint) exposure to BaP of 42-350 ng. This protocol represents de minimus risk.
