Traditional exhaustive extraction methods often overestimate the risk of polycyclic aromatic hydrocarbon （PAH） bioaccessibility to biota. Therefore, reliable assessment methods need to be established. In this study, a composite extraction with hydroxypropyl- β-cyclodextrin （HPCD） and three low-molec...
