- •
Bioaccessibility of AhR-active PAHs in oil-contaminated sediments were assessed.
- •
EDA was performed using a battery of H4IIE-luc in vitro bioassay and GC/MSD analysis.
- •
Concentrations of PAHs in Tenax extracts were ∼20-fold less than Soxhlet extracts.
- •
Major AhR-active PAHs were identified as C1- and C3-chrysene, and C4-phenanthrene.
- •
Bioaccessibility of PAHs appeared to depend on hydrophobicity and oil-weathering.
