Soman (or GD, EA 1210, Zoman, PFMP, A-255, systematic name: O-pinacolyl methylphosphonofluoridate) [1] is an extremely toxic chemical substance. It is a nerve agent , interfering with normal functioning of the mammalian nervous system by inhibiting the enzyme cholinesterase .
However, with sufficient care and support from adults, children can return their stress levels to tolerable or good. [4] Examples of toxic stress are abuse, neglect, violence and overall hardship without adult support. [14] Toxic stress can have a cumulative effect on physical and mental health.
The progressive symptoms of anatoxin-a exposure are loss of coordination, twitching, convulsions and rapid death by respiratory paralysis. The nerve tissues which communicate with muscles contain a receptor called the nicotinic acetylcholine receptor. Stimulation of these receptors causes a muscular contraction.

OPs are one of the most common causes of poisoning worldwide. [2] There are nearly 3 million poisonings per year resulting in two hundred thousand deaths. [2] [3] Around 15% of people who are poisoned die as a result. [2] Organophosphate poisoning has been reported at least since 1962. [7]

Some of the symptoms that result from cell death include loss of motor control, cognitive deterioration and autonomic nervous system dysfunction. Additionally, neurotoxicity has been found to be a major cause of neurodegenerative diseases such as Alzheimer's disease (AD). [citation needed]
Poisoning by a nerve agent leads to constriction of pupils, profuse salivation, convulsions, and involuntary urination and defecation, with the first symptoms appearing in seconds after exposure. Death by asphyxiation or cardiac arrest may follow in minutes due to the loss of the body's control over respiratory and other muscles.
