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.
Pesticide use is widespread in Latin America, as around US$3 billion are spent each year in the region. Records indicate an increase in the frequency of pesticide poisonings over the past two decades. The most common incidents of pesticide poisoning is thought to result from exposure to organophosphate and carbamate insecticides. [62]
[citation needed] Thus a large proportion of pesticides (e.g., malathion), are often included in this class of compounds. Phosphorus can adopt a variety of oxidation states, and it is general to classify organophosphorus compounds based on their being derivatives of phosphorus(V) vs phosphorus(III), which are the predominant classes of compounds.
Among those who work with pesticides the use of protective clothing and showering before going home is also useful. [6] In those who have organophosphate poisoning the primary treatments are atropine, oximes such as pralidoxime, and diazepam. [2] [4] General measures such as oxygen and intravenous fluids are also recommended. [2]
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. [36] [37] [38]
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.
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 ...
A 17-year long, NIEHS-funded study of the links between Parkinson's disease, environment, and genes shows that some pesticides, including paraquat, maneb, ziram, benomyl, and several organophosphate pesticides, including diazinon and chlorpyrifos, contribute to Parkinson's disease onset and progression.
