• PFAS contents and profiles of dab from the German Bight showed clear regional differences. • Of the PFAS analysed, perfluorooctane sulfonate (PFOS) was the dominant substance in terms of quantity in all samples. • Some of the limits for fish as food were exceeded. However, environmental limits are not exceeded. • Statistical analysis of PFAS patterns indicates different sources of individual PFAS.
