In organic chemistry, organophosphates (also known as phosphate esters, or OPEs) are a class of organophosphorus compounds with the general structure O=P(OR) 3, a central phosphate molecule with alkyl or aromatic substituents. [1] They can be considered as esters of phosphoric acid. Organophosphates are best known for their use as pesticides.
Malathion is a pesticide that is widely used in agriculture, residential landscaping, public recreation areas, and in public health pest control programs such as mosquito eradication. [5] In the US, it is the most commonly used organophosphate insecticide.
Illustrative organophosphates and related compounds: phosphatidylcholine, triphenylphosphate, cyclophosphamide, parathion, and zinc dithiophosphate. Phosphoryl thioates are thermodynamically much stabler than thiophosphates, which can rearrange at high temperature or with a catalytic alkylant to the former: [7]: 73–76 SP(OR) 3 → OP(OR) 2 SR
Organophosphates have a cumulative toxic effect to wildlife, so multiple exposures to the chemicals amplifies the toxicity. [19] In the US, organophosphate use declined with the rise of substitutes. [20] Many of these insecticides, first developed in the mid 20th century, are very poisonous. [21] Many organophosphates do not persist in the ...
Pesticides are used in an estimated 200,000+ suicides annually with tens of thousands due to chlorpyrifos. Organophosphates are thought to constitute two-thirds of ingested pesticides in rural Asia. Chlorpyrifos is among the commonly used pesticides used for self-harm. [34] [35] [36]
For its 2024 list revealed on Wednesday, the EWG found overall that 75% of nonorganic produce sampled contained potentially harmful pesticides. The EWG, according to a news release, compiles its ...
Dichlorvos (2,2-dichlorovinyl dimethyl phosphate, commonly abbreviated as an DDVP [1]) is an organophosphate widely used as an insecticide to control household pests, in public health, and protecting stored products from insects. The compound has been commercially available since 1961.
