SPATIOTEMPORAL ANALYSIS OF PERFLUOROALKYL SUBSTANCES IN WHITE-TAILED EAGLE (HALIAEETUS ALBICILLA) NESTLINGS FROM NORTHERN NORWAY-A TEN-YEAR STUDY
Jouanneau, W., B.-J. Bardsen, D. Herzke, T.V. Johnsen, I. Eulaers, and J.O. Bustnes.
Environmental Science & Technology 54(8):5011-5020(2020)
PFAS levels in plasma of white-tailed eagle nestlings from northern Norway were studied from 2008 to 2017. While PFOA and PFNA exposure did not follow a significant time trend, PFOS and PFHxS concentrations decreased over time, and ≥ C11 perfluorinated carboxylic acids seemed to level off during the last four years. This may be evidence for a change in the trend for some of these compounds. The study also investigated the potential of the two main regional airports to act as hotspots for PFAS. Results showed decreasing exposure to PFOA with distance from the airports. The study determined that legislation actions are effective, and continued concern for PFAS exposure of high trophic wildlife is still warranted, even in the northern environment.
