VX (nerve agent)
VX (nerve agent)
VX (/viːˈɛks/) is a type of nerve agent that is classified as a weapon of mass destruction by the United Nations. It is known for its high toxicity and rapid effect on the human body.
Etymology
The term "VX" is derived from "Venomous Agent X". It was first developed in the United Kingdom in the 1950s during research into new pesticides. It is chemically classified as an organophosphate compound.
Description
VX is an amber-colored, odorless, and tasteless liquid that evaporates slowly into the air. It is less volatile than other nerve agents, making it suitable for long-term contamination of areas. It is also highly resistant to degradation by water and common disinfectants.
Mechanism of Action
VX works by disrupting the transmission of nerve impulses in the body. It does this by blocking the enzyme acetylcholinesterase, which is responsible for breaking down acetylcholine, a neurotransmitter that sends signals in the nervous system. This leads to an accumulation of acetylcholine, causing continuous stimulation of the muscles and glands, which can result in symptoms such as convulsions, paralysis, respiratory failure, and death.
