    Abstract. Adult male rats were given drinking water containing either 0 or 150 ppm cyanide for 2 weeks. They were then injected with 5 µCi 75 Seselenite, and excretion of radioactivity in urine and feces was determined. No difference in excretion of 75 Se occurred during the rapid phase, but the cyanidetreated rats (T 1/2 28 days) excreted significantly more 75 Se in urine than control (T 1
