Dichlorvos is a cholinesterase inhibitor, and therefore primarily targets the nervous system, as its mode of action greatly impedes proper nerve function. In humans, a concentration of 2.4 g/m³ can cause death fromacute pulmonary oedema in one minute (Hanslian, 1921). Insecticides of this type inhibit the activities of the cholinesterase enzyme, which in turn leads to an accumulation of acetylcholine. Dichlorvos can be fed to livestock to control botfly larvae in the manure. Workers who came into contact with this chemical over extended periods of time were reported to have experienced the symptoms of acute dichlorvos exposure, and many others that manifest with constant exposure, namely: Dichlorvos is suspected of causing cancer, though its carcinogenic potential has only been observed in animals so far. Principle function of AChE is to terminate the effects of ACh after it is released. CDC.gov Severe poisoning (5 ounces or more of a 5% dichlorvos solution) can result in coma, inability to breathe, and death. There is, however, a related compound, a drug called metrifonate, that has been used to treat parasitic ailments in humans and as a potential treatment for Alzheimer's disease. The compound has been commercially available since 1961 and has become controversial because of its prevalence in urban waterways and the fact that its toxicity extends well beyond insects.
