•Marine fish was analysed as bioindicators of POPs contamination.•Levels for PCDD/Fs and PCBs were below the limits established by EU legislation.•PCDD/F and DL-PCB concentrations decrease from 2006 to 2012.
The results of a surveillance programme on the determination of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and short chain chlorinated paraffins (SCCPs) in marine fish and shellfish species which are fished, commercialised and consumed in the Ebro River Delta area (NE, Spain) are presented. The study included the analysis of five marine fish species (sardine, gilthead sea bream, conger, eel and flounder) and three shellfish species (murex, carpet shell and mussel) collected in 2012 in five fishing harbours near to this area. WHO-TEQ concentrations for PCDD/Fs and dioxin like PCBs (dl-PCBs) ranged from 0.03 to 0.31pg WHO-TEQ2005PCDD/Fg−1wetweight (ww) and from 0.02 to 3.15pg WHO-TEQ2005PCBg−1ww, respectively. All levels were below the maximum concentrations established by the EU Regulation. The PCBs and PCDD/Fs accumulation pattern found in the samples analysed showed a distribution typically reported for marine samples. For marker PCBs and PBDEs, concentration levels ranging from 929 to 57494pgg−1ww and from 36.2 to 827pgg−1ww were obtained, respectively, meanwhile for SCCPs levels were between 3.1 and 141ngg−1ww. Finally, the trends in the levels of PCDD/F and dl-PCBs found from 2006 to 2012 in fish and shellfish species were studied. A slight decrease of PCDD/F and dl-PCB concentrations was found since 2006.
