Abstract
    Brominated flame retardants (BFRs), such as polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD), were measured in pooled eel samples originating from different locations along the river Scheldt, including 2 reference locations (closed water bodies), all situated nearby Oudenaarde. Total HBCD levels (range 70 – 10 100 ng/ lipid weight) in the eel samples were measured by GC-MS and were higher than PBDE levels (40 – 1 010 ng/g lipid weight), probably related to the textile industries nearby Oudenaarde. The predominant PBDE congeners were BDE 47, 100, 99 and 49, originating from the former use of the Penta-BDE formulation. The high variation in contamination levels between the different sampling locations resulted in a variable contribution to the total human exposure through eel consumption, ranging between 3 ng and 327 ng/day for PBDEs for normal eel consumers. Decreasing contamination levels of PBDEs and HBCD over the period of 6 years were observed in eel for the same locations. However, these levels are still an order of magnitude higher than levels reported in other studies in Flanders
