Although some publications regarding the contamination of
PAHs metabolites in fish10,11,22−25 have been reported, the
comparison with other studies is difficult, because, to our
knowledge, there are no reports of the determination of PAH
metabolites in mollusks, namely, in cephalopod samples.
Nonetheless, the results of the present study are corroborated
by a previous work2 that evaluated the concentrations of 18
PAHs in five commercial squid species in Portugal, with
different geographical origins. The results showed that low
