PBDE ranged between 10 and 5811 ng/g lipid weight (lw) with a median value of 81 ng/g lw.

HBCDs ranged between 16 and 4397 ng/g lw, with a median value of 73 ng/g lw. a-HBCD was the dominant isomer in all eel samples. Sediment concentrations of PBDEs were available from four locations and were used to compare the PBDE profile with those in eel. An important shift in the profile was observed, especially for BDE 209. While BDE 209 was only found in 12 eel samples, it was the dominant congener in all sediment samples. This could be due to its metabolisation or degradation in biota combined with the poor uptake of BDE 209 from sediments and its very low water solubility. No HBCDs were detected in any of the sediment samples. No significant correlation could be found between concentrations of PBDEs in eel and sediment from the same location. Comparison with previous studies shows that PBDE and HBCD levels in Flemish eels have decreased rapidly between 2000 and 2006 at particular sites, but alarming concentrations can still be found at industrialized hot spots. This finding is reflected in the human exposure to PBDEs and HBCDs through eel consumption. For average consumers (2.9 g eel/day), intakes ranged between 3 and 2295 ng/day for ? PBDEs (with a median value of 16 ng/day) and between 3 and 1110 ng/day for ? HBCDs (with a median value of 18 ng/day), respectively.
