N2 - Seven West Greenland sledge dog bitches (Canis familiaris) and their three pups were fed 50-200 g of contaminated West Greenland minke whale (Balaenoptera acutorostrata) blubber, and in a control cohort eight sister bitches and their .ve pups were fed a similar amount pork fat. Blood plasma and urine clinical-chemical parameters were measured and compared between the bitches and pups form the control and exposed cohorts. Based on existing reference intervals, Arctic mammals may have blood clinical-chemical endpoint levels that differ from comparable species at lower latitudes. The cortisol:creatinine ratio, protein:creatinine ratio, alkaline phosphatase, cholesterol and inorganic phosphate were signi.cantly highest (ANCOVA: all po0:05) in the pup generation. The cortisol:creatinine ratio, cholesterol, lactate dehydrogenase and creatinine kinase were signi.cantly higher (ANCOVA: all po0:05) in the control group, while glucose was signi.cantly highest (ANCOVA: po0:05) in the exposed group. Furthermore, the blood cholesterol levels indicate that exposure via the diet to marine mammal blubber has a preventive effect on the development of cardiovascular diseases. We therefore suggest that the consumption of contaminated Arctic marine blubber impacted liver and kidney function in adult and pup sledge dogs.
