The subcellular distribution of /sup 239/Pu and /sup 59/Fe 10 days after intravenous injection as a citrate complex was investigated by sucrose density gradient centrifugation in the liver of rat, mouse, and Syrian and Chinese hamsters. Lysosomes were separated from other cell constituents by injection of the nonionic detergent Triton WR 1339 4 days before sacrifice. The Triton-induced decrease in the density of the lysosomes was very similar in all four animal species and was followed closely by a corresponding decrease of the median density of the /sup 239/Pu profiles in rat, mouse, and, to a smaller extent, Syrian hamster. However, in Chinese hamster a clear correspondence between lysosomes and /sup 239/Pu was not found 10 days after nuclide injection. It was concluded that lysosomes are the main storage organelles fo /sup 239/Pu in the liver of rat and mouse and that in all four animal species mitochondria and endoplasmic reticulum do not play any significant role in binding the radionuclide. The relevance of pericellular membranes has to be checked. The distribution patterns of /sup 59/Fe and /sup 239/Pu were quite different.
