Median incapaciting dose

Because of the ease of assessing lethality, many toxicity studies have concentrated upon determination of LD50 or LCtso. Of more importance in the military context are the incapacitating effects of compounds, and the ID50 (median incapacitating dose) or the ICtso are important descriptors of a compound s toxicity. These are, of course, much more difficult to determine in animals and the relevance of such determinations to likely effects in humans is open to doubt. Of even more military importance are the parameters ICts and ICtio, although to determine these... 

Soman has a vapor density more than six times heavier than air. It is a colorless liquid with a fruity odor, when pure, and an amber or dark brown color with an oil of camphor odor, when impure. Doses of soman that can cause death may be only slightly larger than those that produce symptoms. The median incapacitation dose for soman is unknown. In contact with water, it will hydrolyze to form hydrogen fluoride (HF).
