| Comments |
Tabun is a colorless to brown liquid with a fruity odor and a vapor pressure of 0.037 at 68 degrees F. It persists in the soil with a half-life of 1-1.5 days. [Jane, p. 81-2] "TABUN (GA) has an especially rapid onset of action, which on a weight basis is less potent than VX. The human fatal dose has been reported to be 0.01 mg/kg." [HSDB] "As little as one drop of VX on the skin can be fatal and 1 to 10 mL of GA, GB, or GD can be fatal." [ATSDR Medical Management] |
