Abstrakt: The present study aimed to evaluate concentrations of 16 priority PAHs in the mussel Perna perna and oyster Crassostrea rhizophorae of the Santos Estuary (Brazil) and the potential risk to human health associated with the consumption of these species. The levels of ΣPAHs in the tissues of bivalves ranged from 96.94 to 988.76 μg/kg for mussels and from 88.38 to 138.62 μg/kg for oysters. A general trend of higher concentrations of PAHs was observed according to the increase in log K ow values in both species. The estimated amount of ΣPAHs via mussel and oyster intake ranged from 1.0 to 3.2 ng/kg and from 0.4 to 1.2 ng/kg of body weight per day, respectively. The calculated THQs, HI and CRs for the regular consumption of raw bivalves followed the internationally acceptable limits and represent a low risk to human health.
