METABOLISM OF Zn$sup 65$ IN THE RAT
Technical Report
·
OSTI ID:4236124
The gastrointestinal absorption of Zn/sup 65/ was determined after feeding solutions of different specific activities and following administration of suspensions of plant and animal tissues containing the isotope. Following intravenous administration, Zn/sup 65/ was excreted largely via the feces. Early deposition was highest in the visceral organs which lost the isotope rapidly. Smaller amounts of Zn/sup 65/ deposited in bone were retained with a biological half life of 250 days. Based on bone as the critical organ with an effective half life of 125 days, the MPC for Zn/sup 65/ in water was calculated to be 1 x 10/sup -2/ mu c/ml. (auth)
