Effect of TMF choice on TL 4-normalized PFOS concentrations (µg kg−1 ww) in composite samples of fillet (F) from the rivers Moselle (M) and Havel (H). TMF 2.60: geometric mean for stream ecosystems [33, 58]; TMF 3.13: geometric mean of stream and lake ecosystems [33, 39, 40, 58]; TMF 4.98: geometric mean of lake ecosystems TMFs [39, 40]; samples in Moselle and Havel are arranged according to increasing TL; red line: EQS (9.1 µg kg−1 ww)
