Circumpolar contamination in eggs of the high‐Arctic ivory gull Pagophila eburnea
Abstract The ivory gull Pagophila eburnea is a high‐Arctic species threatened by climate change and contaminants. The objective of the present study was to assess spatial variation of contaminant levels (organochlorines [OCs], brominated flame retardants [BFRs], perfluorinated alkyl substances [PFAS...
