Chlorinated hydrocarbons and trace elements in eggs of South polar skua and Adelie penguin
Bird eggs provide useful information about pollutant residues at feeding sites, but can reflect levels of contamination over a wider area. As top predators in marine systems, skuas (Catharactidae) are ideal species through which to monitor trends in oceanic pollution (Furness 1987). South Polar Skua...
