Abstract

A number of laboratory studies have been carried out to characterize the bioavailability of two transuranic elements for a gastropod in several natural waters. In these experiments the behaviour of initial pure oxidation states of 237-Pu and 241-Am and their distribution patterns in the gastropod were determined with the aid of the following methods. - Chemical separation technique to characterize the particle and soluble species of the transuranics in the aqueous media; - Thenoyltrifluoracetone (TTA) solvent extractions and the method of Lovett and Nelson to determine the oxidation of the transuranic in solution; - Methacrylate embedding and autoradiographs to locate the deposition sites of the transuranics in animal tissues; - Biochemical technique (differential centrifugation and gel filtration) to clarify the subcellular distribution of the transuranics. The present paper describes the techniques above and discuss their advantages and limitation.
