Black RM, Clarke RJ, Read RW, Reid MTJ [1994]. Because of its extreme toxicity, VX is considered a weapon of mass destruction. It is a clear odorless and tasteless liquid with an appearance similar to that of motor oil. The mixture is agitated as the VX is added and the agitation is maintained for a minimum of one hour. Photograph: OJO Images/Rex/Shutterstock Like sarin, it is tasteless and odorless. VX gas is a terrifying nerve agent developed specifically to be used in chemical warfare. VX … Application of gas-chromatography mass-spectrometry and gas-chromatography tandem mass-spectrometry to the analysis of chemical warfare samples found to contain residues of the nerve agent sarin, sulfur mustard and their degradation products. Unlike sarin, it is thick and oily. VX is an extremely toxic synthetic chemical compound in the organophosphorus class, specifically, a thiophosphonate.In the class of nerve agents, it was developed for military use in chemical warfare after translation of earlier discoveries of organophosphate toxicity in pesticide research. The VX nerve agent that killed North Korea’s Kim Jong-nam is 100 times more deadly than the nerve gas sarin. If phasing of the VX/decon solution continues after 5 minutes, an amount of denatured ethanol equal to a 10 wt.% of the total agent/decon will be added to help miscibility. VX poisoning can be treated immediately with two antidotes: atropine and pralidoxome chloride. The yellow safety cap will remain on the clip and the atropine autoinjector will now be armed, and the needle will eject from green tip (Figure 2) There is no one-stop antidote for all symptoms. VX vapour is ten times more lethal than the liquid, causing poisoning symptoms in seconds. VX, invented by a British chemist in the early 1950s, is a nerve gas even more deadly than sarin. First synthesised in Britain in the 1950s, VX is up … TABUN 46 hours SARIN 5 hours Reputedly short for “venomous agent X,” VX is the most toxic nerve agent: Several milligrams absorbed through the skin is a lethal dose. Workers stand in front of containers of VX nerve agent at the Newport Chemical Depot in western Indiana, in November 1997. Nerve agent VX is a member of the organophosphate family, similar to present day insecticides. VX can become an aerosol (very small droplets) through explosion, or a vapor through heating. Remove MARK 1 Kit from its protective pouch; Grasp the atropine autoinjector (the smaller of the two) and remove it from slot number 1 of the plastic clip. Antidote administration: Administer up to 3 Mark 1 Kits as needed . WATER J Chromatogr A 662(2):301-321. Chemical signals are transmitted between nerve cells by means of small molecules called neurotransmitters. VR (Russian VX, Soviet V-gas, Substance 33, R-33, Agent "November") is a "V-series" unitary nerve agent closely related (it is an isomer) to the better-known VX nerve agent. ... Who has VX nerve gas. Kim Jong-nam, the murdered half-brother of North Korea's leader, had a dozen vials of antidote for lethal nerve agent VX in his bag on the day he was poisoned, a Malaysian court has been told.
