  1. Significant differences in mean analyte concentrations among the organisms are indicated by different capital letters. Only compounds that were detected in more than 50% of the samples of a particular species were included in these analyses
  2. ain 2016 PFUnDA, PFBS and PFHxS were not analysed in the fish samples; therefore, the LOQ and concentrations of these analytes were determined on the samples from all years, excluding 2016
