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 ...
Organophosphate poisoning is poisoning due to organophosphates (OPs). [4] Organophosphates are used as insecticides , medications, and nerve agents . [ 4 ] Symptoms include increased saliva and tear production, diarrhea , vomiting, small pupils , sweating, muscle tremors, and confusion. [ 2 ]
Lead is a potent neurotoxin whose toxicity has been recognized for at least thousands of years. [97] Though neurotoxic effects for lead are found in both adults and young children, the developing brain is particularly susceptible to lead-induced harm, effects which can include apoptosis and excitotoxicity. [97]
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 ...
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.
Beyond their acute toxicity, long-term exposure to organophosphates is associated with a number of heath risks, including organophosphate-induced delayed neuropathy (muscle weakness) and developmental neurotoxicity. [28] [43] [44] There is limited evidence that certain compounds cause cancer, including malathion and diazinon. [45]
The term developmental toxicity has widely replaced the early term for the study of primarily structural congenital abnormalities, teratology, to enable inclusion of a more diverse spectrum of congenital disorders. The substances that cause developmental toxicity from embryonic stage to birth are called teratogens. The effect of the ...
Novichok (Russian: Новичо́к, lit. 'newcomer, novice, newbie' [1]) is a family of nerve agents, some of which are binary chemical weapons.The agents were developed at the GosNIIOKhT state chemical research institute by the Soviet Union and Russia between 1971 and 1993.
