Organophosphorus chemistry is the scientific study of the synthesis and properties of organophosphorus compounds, which are organic compounds containing phosphorus. [1] They are used primarily in pest control as an alternative to chlorinated hydrocarbons that persist in the environment.
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]
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.
Specific types of natural pesticides include botanical pesticides- natural occurring chemicals extracted directly from plants or minerals; biochemical pesticides- uses substances like plant hormones that could interfere with pests mating or other behaviors; and microbial pesticides- pesticide with microorganisms like fungi, viruses, or bacteria ...
Pesticide poisoning is an important occupational health issue because pesticides are used in a large number of industries, which puts many different categories of workers at risk. Extensive use puts agricultural workers in particular at increased risk for pesticide illnesses.
Methamidophos, trade name "Monitor," is an organophosphate insecticide. Crops grown with the use of methamidophos include potatoes [1] and some Latin American rice. [2] Many nations have used methamidophos on crops, including developed nations such as Spain, United States, Japan, and Australia. Due to its toxicity, the use of pesticides that ...
In January 2017, four children died at a trailer park in Amarillo, Texas, after the pesticide was used under the home to kill rats. [ 21 ] Several incidents of death in travelers in Thailand and other parts of Southeast Asia may have been caused by aluminum phosphide or chlorpyrifos , an organophosphate insecticide , used in an attempt to kill ...
Pesticides are widely used by farmers to control plant pests and enhance production, but chemical pesticides can also cause water quality problems. Pesticides may appear in surface water due to: direct application (e.g. aerial spraying or broadcasting over water bodies) runoff during rain storms; aerial drift (from adjacent fields). [3]: p.2–22
