[Role of lysosomes in the phenomenon of cadmium concentration. Microanalysis by X-ray spectrography].

Investigations were performed on the midgut gland cells of the Crayfish Pontastacus leptodactylus after intoxication with cadmium. The storage of cadmium occurs within the lysosomes where the mental coexists always with sulfur zinc and copper. The simultaneous presence of these elements favours the hypothesis that metallothioneins may be located within the lysosomes.
