 Nerve agent - Wikipedia, the free encyclopedia
Nerve agents (also known as nerve gases, though these chemicals are liquid at room temperature) are a class of phosphorus-containing organic chemicals (organophosphates) that disrupt the mechanism by which nerves transfer messages to organs.
Nerve agents can be absorbed through the skin, requiring that those likely to be subjected to such agents wear a full body suit in addition to a respirator.
Nerve agents were not used by Iraq in the Gulf War, though a number of U.S. and U.K. personnel were exposed to them when the Khamisiyah chemical depot was destroyed.

Nerve agents can be absorbed through the skin, requiring that those likely to be subjected to such agents wear a full body suit in addition to a gas mask.
Nerve agents were not used by Iraq in the Gulf War, despite widespread fears to the contrary.
Iraq briefly used chemical weapons, including nerve agents, during the Iran-Iraq war of 1981-1988; the Kurdish village of Halabja was exposed to nerve agents, and controversy still rages as to whether this was a deliberate or accidental act.

 ATSDR - MMG: Nerve Agents: Tabun (GA); Sarin (GB); Soman (GD); and VX
Nerve agents are readily absorbed from the respiratory tract.
Nerve agents alter cholinergic synaptic transmission at neuroeffector junctions (muscarinic effects), at skeletal myoneural junctions and autonomic ganglia (nicotinic effects), and in the CNS.
Nerve agents are extremely toxic and can cause loss of consciousness and convulsions within seconds and death from respiratory failure within minutes of exposure.

 Nerve agent - Wikipedia, the free encyclopedia
Nerve agents are highly toxic chemical agents that poison the nervous system and disrupt bodily functions that are vital to an individuals survival.
The initial stages of symptoms of an individual exposed to a nerve agent may vary depending on the particular agent and amount of the agent the person was exposed to.
Poisoning by a nerve agent leads to contraction of pupils, profuse salivation, convulsions, involuntary urination and defecation, and eventual death by asphyxiation as control is lost over respiratory muscles.

 Nerve Agent: GB
GB is a "first generation" nerve agent, identified in 1938 as a potential chemical agent by German researchers examining toxic organophosphates as a result of the discovery of GA (Tabun).
The immediate treatment for nerve agent intoxication is intravenous injection of 2 mg atropine sulfate (intramuscular injection should be considered if the patient is hypoxic and ventilation can not be initiated, as there is a risk of ventricular fibrillation).
GB was the first agent to be employed to cause mass casualties by nonstate actors when it was used for attacks by the Aum Shinrikyo cult in Japan during 1994 and 1995.

 Research suggests better nerve agent treatment
Because of concerns about terrorists one day using such deadly nerve agents as sarin, soman, tabun and VX, the two are urging the government and medical researchers to investigate potentially more effective treatments.
Evidence indicates that such nerve agents are lethal, in part due to increasing acetylcholine in the brain, Janowsky said.
Nerve agents greatly increase the natural neurotransmitter acetylcholine in the body, he said.

 Nerve Agent Precursors: Bifluorides
Bifluorides are used as a source of the fluorine atom in the synthesis of all of the G-type nerve agents except Tabun, in which the fluorine atom is replaced by a cyanide group.
The quantities needed for manufacture of a stockpile of G agent would be miniscule in comparison.
Bifluorides are also used in the manufacture of wood preservatives and in soldering fluxes.

 Intelligence Update: Chemical Warfare Agent Issues During the Persian Gulf War, April 2002
The Iraqis were producing large quantities of the blister agent sulfur mustard by early 1983 and the nerve agent tabun by 1984.
Nerve agents typically act rapidly (within seconds of exposure) and may be absorbed through the skin or through the respiratory tract.
The primary Iraqi chemical agents available for release at the time of Desert Storm were the blister agent sulfur mustard; the mixed nerve agents sarin and “cyclosarin” (also known as GB and GF, respectively); and the riot control agent CS—all well-known compounds.

 A look back at Gulf War One
Analysis and modeling of Iraq's production facility lead us to estimate that Iraq is currently producing at least 6 tons per day of the blister agent mustard, between 1 and 2 tons per day of the nerve agent tabun, and limited amounts of the nerve agent saRin.
In addition, it is researching pro- duction of the nerve agents soman, VG, and VX, AND the psyChochemicals BZ and EA3443.

In sum, tabun production is relatively easy because it does not include the difficult alkylation reaction needed to make the other nerve agents.
The first militarized nerve agent and the simplest to produce, tabun (GA), is made from four precursor chemicals: phosphorus oxychloride (POCl
The major technical hurdle in tabun synthesis is the cyanation reaction (in which a cyanide group is added to the central phosphorus), because of the difficulty of containing the toxic hydrogen cyanide HCN gas used as the reagent..
