Abstract

Concentrations and congener specific profiles of PCBs, PCDDs and PCDFs were determined in various edible fish from the Adriatic Sea. PCBs were the dominant chemicals (116–1980 ng g−1 lipid wt), followed by PCDFs (ND-58.3 pg g−1 lipid wt) and PCDDs (ND-20 pg g−1 lipid wt). The levels of these contaminants varied among species. Benthic organisms possessed the highest concentrations, followed by demersal and pelagic fish species. PCB and PCDD/F accumulation pattern in the samples analysed showed a distribution typically reported for marine samples. The mean weekly intake of toxic equivalency (TEQ) was estimated to be 0.84 pg TEQs/kg bw/week. The dioxin-like PCBs accounted for more than 77% of this intake, followed by PCDDs (15.5%) and PCDFs (13.1%). In general, the samples analysed in this survey can be considered safe with regard to the levels obtained and the in-force legislation, nevertheless the consumption of some species may be of significance importance for consumer health.

Research highlights► This study describes the content of PCBs, PCDDs and PCDFs in different seafood. ► This study shows the congener-specific analysis of PCBs and PCDD/Fs. ► The results are discussed in the light of maximum levels permitted by European Union. ► Contaminant levels do not show evidence of risk for consumers, except for consumption of some species.
