"I can't find LCI50 estimates (dose in terms of mg*min/m3 at which inhalation kills half of the victimes)for TEPP, but a public document Chemical Terrorism generated by the Canadian Intelligence Security Service, describes both TEPP and the less toxic parathion as "almost as toxic as their military counterparts". "

I don't think any one will be less dead, for being esposed to a lethal dose of TEPP, Parathion, etc. (all organophosphate cholinesterase inhibitors(, than being exposed to VX, Sarin, Tabun, etc.

The big difference between military nerve agents and commercial pesticides is: The military agents have a longer persistence in the environment.

Exactly (though non-persistent agents can be even more useful than persistent ones if one wants to launch an attack or counterattack).

Which still leads to the question I asked originally: which pesticides were being horded in Iraqi military facilities?
