In this project five pooled samples of mackerel (Scomber scombrus) and 25 individual eel (Anguilla anguilla) from the Grenlandfjord area (Telemark) were analysed for the elements arsenic, cadmium, mercury, lead, PCDD/F and dl PCB, PBDEs, sum HBCD and total fat. Mackerel had concentrations of metals, PCDD/F, dl PCB,PBDE and total HBCD consistent with the concentrations reported earlier (www.nifes.no/seafooddata). None of the concentrations exceeded the EU's upper limits, where such limits exist. The concentrations of cadmium and lead in eels were low and none of the 25 fish had levels that exceeded the EU's upper limit. This was also the case for mercury, although the results clearly showed that some of the fish were exposed to mercury without exceeding the EU's upper limit of 1.0 mg / kg wet weight. The concentrations of total PBDE and HBCD were relatively low and comparable with that found in other oily fish, such as mackerel and herring. The concentrations of sum PCDD/F showed values which exceeded the EU's upper limit of 4 ng TEQ/kg wet weight for 21 out of 25 samples. The concentrations of sum PCDD/F and dl PCB in eels showed that values ranged from 3.8 to 92.5 ng TEQ/kg wet weight. Thirteen samples had values which exceeded the EU's upper limit of 12 ngTEQ/kg wet weight. As, Cd, Hg, Pb, dioxins, dioxin-like PCBs, non-dioxin like PCBs, PBDE and PFAS were determined in fillet of mackerel and eel caught in the fjords of Telmark. The results showed high concentration of sum dioxins and furans in fillet of eel. Low levels were, however, found for all analyses analysed in fillets of mackerel and heavy metals in fillets of mackerel.
