  1. a: PAH concentrations converted to BaP equivalent concentrations using toxic equivalency factors [24].
  2. b: [34].
  3. c: [33].
  4. d: [35].
  5. e: [37].
  6. Cancer risk was assessed using the maximum Cs, an ED of 70 years, an EF of 153 days, BW of 80 kg, an AT of 25550 days, and CSForal of 7.3 (mg kg-1 d-1)-1.
