An Estimate of the Human Inhalation L(Ct)50 for GB

Abstract

Methods of estimating the inhalation L(Ct)50 are outlined. Reasons are suggested for basing calculations on the ratio ChE50: LD50; this gives an estimate of the average L(Ct)50 that is probably valid to within =33% for brief exposures, with wider limits for longer exposures. The L(Ct)50 varies with the metabolic state of those attacked. Under resting conditions, the average figure is probably at least 135 mg.min/cu m; with activity the average may be less than 50 mg.min/cu.m. These figures represent the best possible estimate based on data available from both U.S. and the U.K.
