Heavy metals in Greenland seabirds
From six Greenland districts we report the concentration of Zn, Cd, Hg and Se in muscle (pectoral), liver and kidney for 320 seabirds of the following species: Cepphus grylle, Uria lomvia, Clangula hyemalis, Mergus serrator, Larus glaucoides, L. hyperboreus, Rissa tridactyla, Pagophila eburnea, Fulm...

On a wet weight basis, the Zn concentration in liver and kidney is c. three times that of muscle. Gulls and the fulmar possess significantly more Zn in muscle than do other seabirds. The Cd concentration in liver and kidney is c. 20 and 80 times higher than in muscle, whereas the Hg concentration in liver and kidney is three to five times higher than that of muscle.
