The first was a rapid phase, which probably represented the distribution of (14)C-t-butyl alcohol from the blood to other body tissues. The second represented a first-order elimination of radioactivity from the blood with a half-life of approximately 8 hr, indicating that (14)C-t-butyl alcohol was being eliminated primarily as metabolic product(s).
