Soman was the third of the so-called G-series nerve agents to be discovered along with GA (tabun), GB (sarin), and GF (cyclosarin). When pure, soman is a volatile, corrosive, and colorless liquid with a faint odor like that of mothballs or rotten fruit. [3] More commonly, it is a yellow to brown color and has a strong odor described as similar ...
Ammonia toxicity is often seen through two routes of administration, either through consumption or through endogenous ailments such as liver failure. [ 89 ] [ 90 ] One notable case in which ammonia toxicity is common is in response to cirrhosis of the liver which results in hepatic encephalopathy , and can result in cerebral edema (Haussinger ...
Neurotoxicity is a form of toxicity in which a biological, chemical, or physical agent produces an adverse effect on the structure or function of the central and/or peripheral nervous system. [1] It occurs when exposure to a substance – specifically, a neurotoxin or neurotoxicant – alters the normal activity of the nervous system in such a ...
Toxicity assays have found that the LT 50 of poneratoxin, delivered via injections of genetically engineered viruses, to S. frugiperda larvae, was at 131 hours post-injection. A dose of 10 5 pfu of poneratoxin was sufficient to kill the S. frugiperda larvae, and a dose of 10 ng could paralyze them. [1]
The toxicity did not escape military notice and some of the more toxic materials had been sent to Porton Down for evaluation. After the evaluation was complete, several members of this class of compounds became a new group of nerve agents, the V agents (depending on the source, the V stands for Victory, Venomous, or Viscous).
A toxicologist working in a lab (United States, 2008)Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms [1] and the practice of diagnosing and treating exposures to toxins and toxicants.
However, compared with other highly toxic nerve agents like soman or sarin, VX undergoes relatively slow "aging". Aging is a time-dependent side reaction (loss of an alkoxyl group) that occurs on nerve agents after phosphorylation and renders the nerve agent-acetylcholinesterase complex highly resistant to regeneration by any known antidote.
