Abstract

Abstract: We report blood and feather concentrations of elements in the Baltic Sea and Arctic population of common eiders ( Somateria mollissima ). The endangered Baltic Sea population of eiders was demonstrably affected by element pollution in the 1990s. While blood concentrations of Hg were higher in Baltic breeding eiders, blood Se, As and Cd concentrations were higher in Arctic eiders. Blood concentrations of Pb, Cr, Zn and Cu did not differ between the two populations. While blood Pb concentrations had declined in Baltic eiders since the 1990s, Hg concentrations had not declined, and were above concentrations associated with adverse oxidative effects in other bird species. Inconsistent with blood concentrations, feather concentrations suggested that Pb, Zn, and Cd exposure was higher in Baltic eiders, and that Hg exposure was higher in Arctic eiders. Our study thus emphasizes the need for comprehensive evaluation of toxic element status, covering the annual cycle of a species. Graphical abstract: Highlights: First report on element concentrations in blood of common eiders in Svalbard Updated blood element concentrations for Baltic eiders are reported. Blood concentrations of Hg in Baltic eiders have not declined in the last 20 years. Blood concentrations of Pb in Baltic eiders have declined during the last 20 years.
