Abstract
Levels of polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers
(PBDEs) were determined in the muscle and liver of European hakes
(Merluccius merluccius, L.) from the Mediterranean and Atlantic coasts
(France). The liver was always the most contaminated organ by both groups of
compounds. Hakes from the Gulf of Lions (Mediterranean) present
concentrations of PCBs and PBDEs 1.6 to 13.5 times higher than hakes of a
similar size from the Bay of Biscay (Atlantic). Although PCBs present higher
levels compared to PBDEs, their concentrations were significantly correlated.
The contaminant patterns in hakes were similar in the two studied areas, and
were dominated by higher chlorinated PCBs (CB153, 138, 180 and 170), and
lower brominated PBDEs congeners (BDE47, 100, 49, and 99). Concentrations
globally increase with hake size, and males appear to be more contaminated than
females of the equivalent size. However, the compound levels also depend on the
physiological status of fish.
Keywords: Merluccius merluccius, demersal fish, polychlorinated biphenyls,

1 Introduction
During recent decades, persistent halogenated compounds (PHCs) have been
largely used and emitted to the environment. Two compound groups regularly
found in marine biota are polychlorinated biphenyls (PCBs) and polybrominated
