[Effects of temperature on the bioaccumulation of cadmium by the crayfish Ponstacus leptodactylus. Microanalysis by X-ray spectrography and secondary ion emission].

Low temperatures (10 +/- 1 degrees C) induce a rapid entry of cadmium into the body across the gills and gut; higher temperatures (20 +/- 1 degrees C) induce a medium and long term absorption and storage of the metal in the digestive gland and its long term accumulation in the exoskeleton. From a methodical point of view, electron microprobe appears more suitable than secondary ion emission microanalysis for the detection of cadmium.
