salicylate is used to relieve symptoms of BZ and other glycollate
casualties.
21. Toxicity.
The property possessed by a material which enables it to
injure the physiological mechanism of at organism by chemical means, with
the maximum effect being incapacitation or death.
22. Toxin.

inhaled, swallowed, or injected into man or animals, will cause illness or
death.
23. Training Agent.

target area where a position is the target for a direct attack by one or
more chemical agents delivered either by air or ground means.
29. Off-target Attack.
Residual chemical agent clouds drift onto
positions or where personnel moving across country encounter toxic clouds or
surface contamination.
30. Median Lethal Dosage (LCt50).
The LCt50 of a chemical agent is the
dosage (vapor concentration of the agent multiplied by the time exposure)
that is lethal to 50 percent of exposed unprotected personnel at some given
breathing rate. The unit used to express LCt50 is mg-min/m3.
31. Median Incapacitating Dosage (ICt50) The ICt50 of a chemical agent is
the amount of inhale vapor that is sufficient to disable 50 percent of
expressed unprotected personnel. The unit to express ICt50 is mg-min/m3.
