The incessant back-and-forth on chemical weapons and Syria is almost dizzying as of Monday, Sept. 9, 2011. One heard that the nation's (Syria) regime - and the rebels - are threatening a chemical weapons war. Or was that a rumor? Then there was news of Russia reasoning with the regime to turn over the chemical weapons to international authorities.
The CIA has previously prepared an excellent report describing types of chemical weapons.
The first of these on this list would be sarin-filled artillery rockets from a previous engagement (Iraq).
The second on this list would be sarin-filled chemical rounds (Iraq).
The third on this list are binary chemical weapons turned into IEDs (Improvised Explosive Devices). These were binary IEDs (Improvised Explosive Devices).
Sixth - the CDC prepared a simple diagram regarding the toxicity and lethality of Sarin. The ATSDR (Agency for Toxic and Substances and Disease Registry) has prepared a list concerning the toxicity of it and other chemical agents.
Seventh is one way to "live detect" chemical weapons (like Sarin) in the wild - portable isotopic neutron spectroscopy. This and other physical methods can detect the presence of chemical weapons.
Eighth - chemical weapon antidotes are available - but should only be possessed/managed by medical and related professional personnel.
It is beyond the scope of this single list to cover the entire universe of material on chemical weapons, detection and antidotes.
