The health effects associated with organophosphate poisoning are a result of excess acetylcholine (ACh) present at different nerve synapses and neuromuscular junctions across the body. Specifically, acetylcholinesterase (AChE), the enzyme that normally and constantly breaks down acetylcholine, is inhibited by the organophosphate substance.
Organophosphate-induced delayed neuropathy (OPIDN), also called organophosphate-induced delayed polyneuropathy (OPIDP), is a neuropathy caused by killing of neurons in the central nervous system, especially in the spinal cord, as a result of acute or chronic organophosphate poisoning.
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 ...
Malathion, one of the first organophosphate insecticides. It remains important as a Vector control agent. Organophosphates are best known for their use as pesticides. The vast majority are insecticides and are used either to protect crops, or as vector control agents to reduce the transmission of diseases spread by insects, such as mosquitoes ...
Health effects of pesticides may be acute or delayed in those who are exposed. [1] Acute effects can include pesticide poisoning, which may be a medical emergency. [2] Strong evidence exists for other, long-term negative health outcomes from pesticide exposure including birth defects, fetal death, [3] neurodevelopmental disorder, [4] cancer, and neurologic illness including Parkinson's disease ...
In part, neurotoxins have been part of human history because of the fragile and susceptible nature of the nervous system, making it highly prone to disruption. The nervous tissue found in the brain , spinal cord , and periphery comprises an extraordinarily complex biological system that largely defines many of the unique traits of individuals.
If one is regularly using carbamate and organophosphate pesticides, it is important to obtain a baseline cholinesterase test. [ 25 ] [ 26 ] Cholinesterase is an important enzyme of the nervous system, and these chemical groups kill pests and potentially injure or kill humans by inhibiting cholinesterase .
Neurotoxicity can occur at any age and its effects may be short-term or long-term, depending on the mechanism of action of the neurotoxin and degree of exposure. Certain metals are considered essential due to their role in key biochemical and physiological pathways, while the remaining metals are characterized as being nonessential.
