Abstract

The biological half-life of manganese and some factors influencing it have been studied in man. The disappearance of manganese from the body in normal subjects is described by a curve having two exponential components. An average of 70% of the injected material was eliminated by the “slow” pathway. The half-time characterizing this component showed a small variation in normal subjects and had an average value of 39 days. The half-time for the “fast” component also showed a small variation and had an average value of 4 days.
