Levels of polychlorinated dibenzo-p-dioxins, dibenzo-p-furans and polychlorinated biphenyls in farmed sea bass (Dicentrarchus labrax) and sea bream (Sparus aurata) from Turkey

Farmed European sea bass and Gilthead sea bream were obtained from four different fish farms in Turkey during 2008–2009, for determination of 17 2,3,7,8-Cl-substituted PCDDs and PCDFs, and coplanar and indicator PCBs. Concentrations of ∑PCDD/Fs and DL-PCBs, as TEQ, in fish samples, ranged from 0.14 to 0.70 pg TEQ(1998) g−1 wet weight and from 0.46 to 4.51 pg TEQ(1998) g−1 wet weight, respectively. The concentrations of total indicator PCBs in fish samples ranged from 3.1 ng g−1 to 22.1 ng g−1 wet weight. Concentrations of PCDD/Fs and DL-PCBs were below the EU regulation (EC No. 1881/2006) limits.
