Methylene Chloride Vapor in Expired Air of Human Subjects

Abstract

Abstract The results of experimental studies of methylene chloride vapor in expired air of human subjects exposed to low, well-controlled concentrations of solvent vapor are presented. Analysis of the expired air data reveals that methylene chloride is excreted principally in the expired air. The rates of “buildup” and die-away” of the vapor in the expired air are suggested as indicators of the distribution of the solvent in body tissues.
