Zinc, cadmium and selinium in Greenland fish
Concentrations of zinc, cadmium, mercury and selenium in muscle, liver, kidney, spleen and bone in marine fish from Greenland are presented. Tissue differences are apparent for all elements. Except for mercury, higher concentrations are found in liver and kidney than in muscle. In general, the mercu...
