The United States and Russia continued producing and stockpiling these nerve agents after the War. In the s another nerve agent, "VX," was produced in England. ACh is released at the axon terminal. ACh crosses the synaptic cleft.
ACh binds with a receptor on the post-synaptic membrane. ACh continues to work and more ACh builds up in the synapse.

Wanderlind , Lucas M. Eventually, you die either through asphyxiation or cardiac arrest. The chemicals work by disrupting the central nervous system. The body constantly has to remove those acetylcholine molecules from the receptors, otherwise there would be a dangerous build-up. It uses an enzyme called acetylcholinesterase AChE to do that. However, a nerve agent stops acetylcholinesterase from doing its job. Antidotes do exist, one being atropine , but have to be administered quickly, otherwise the effect of the nerve agent cannot be reversed.
Some antidotes can be administered as prophylactics to troops about to go into battle, if there is a risk of nerve agents being employed. This is obviously a real problem in a civilian situation, where there is no expectation of encountering these chemicals.
We do not yet know which kind of nerve agent poisoned Skripal. While they all work in similar way, different approaches may be needed for decontamination. To decontaminate streets and other hard surfaces, you can use water to flush it out — making sure to use enough to properly dilute the chemical. This works well for the more volatile sarin, which tends to evaporate easily or slowly get broken down by moisture.
However, other substances, such as VX, are less volatile and reactive. In this case, bleach and alkali can be used to break the molecules down. Either way, nerve agents are horrendously lethal and chemical warfare is an obscene use of chemicals.
