Major and minor element concentrations in the livers of polar bears (Ursus maritimus) from Greenland, Canada and Alaska
To assess geographic distributions of elements in the Arctic we compared essential and non-essential elements in the livers of polar bears (Ursus maritimus) collected from five regions within Canada in 2002, in Alaska between 1994 and 1999 and from the northwest and east coasts of Greenland between...
