Legacy persistent organic pollutants (POPs) in archive samples of wild Bluefin tuna from the Mediterranean Sea

摘要

Polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) were quantified in archive samples of dorsal white muscle of the wild Bluefin tuna (BFT) (n=9) collected in the central Adriatic. PCBs were the predominant organochlorine (OC) compounds (60.8-69.4% of the total OC load) found. The contribution of HCB and SHCHs was significantly lower, ranging fromLOD (alpha- and beta-HCH) to 1.5% (gamma-HCH). p,p'-DDE was the predominant OCP compound (60-89% of the SOCPs). PCB and DDT levels were comparable to the values previously found for tuna from the Mediterranean Sea, known as one of the areas most polluted by PCBs.
