PFAS in eggs of Arctic breeding geese
PFASs was detected in all eggs of barnacle geese, however these concentrations were very low and are representative of terrestrial feeding species.
It appeared that these pollutants did not affect lipid or protein concentration in eggs. However, lipid content in eggs increased with nest hatching date, and warrants further investigation.
The barnacle geese are protected but are still increasing in population in northern Norway and Svalbard. Changes in this status may have consequences on human health effects, and this information (e.g. concentrations in eggs may be useful information). In terms of wildlife implications, species that feed on this species are unlikely of risk of exposure to high levels of pollutants (e.g. polar bears).
