Bioaccumulation of Per and Polyfluoroalkyl Substances in Antarctic Breeding South Polar Skuas (Catharacta maccormicki) and Their Prey
Per and polyfluoroalkyl substances (PFASs) are found in Antarctic wildlife, with high levels in the avian top predator south polar skua ( Catharacta maccormicki ). As increasing PFAS concentrations were found in the south polar skua during the breeding season in Antarctica, we hypothesised that avai...
