DNA damage in Arctic seabirds: Baseline, sensitivity to a genotoxic stressor, and association with organohalogen contaminants
Abstract Environmental contaminants are found throughout Arctic marine ecosystems, and their presence in seabirds has been associated with toxicological responses. However, there are few studies of genotoxicity in Arctic avian wildlife. The purpose of the present study was to quantify deoxyribonucle...

Abstract Environmental contaminants are found throughout Arctic marine ecosystems, and their presence in seabirds has been associated with toxicological responses. However, there are few studies of genotoxicity in Arctic avian wildlife.

Blood was sampled from common eider ( Somateria mollissima ), black guillemot ( Cepphus grylle ), black‐legged kittiwake ( Rissa tridactyla ), glaucous gull ( Larus hyperboreus ), arctic skua ( Stercorarius parasiticus ), and great skua ( Stercorarius skua ) in Kongsfjorden, Svalbard (Norway).
