Exposure to any of the above-listed organophosphates may occur through inhalation, skin absorption, and ingestion, most commonly of food that has been treated with an OP herbicide or insecticide. Exposure to these chemicals can occur at public buildings, schools, residential areas, and in agricultural areas.
Organophosphate insecticides are acetylcholinesterase inhibitors, which disrupt the transmission of nerve signals in exposed organisms, with fatal results. The risk of human death through organophosphate poisoning [ 32 ] was obvious from the start and led to efforts to lower toxicity against mammals while not reducing efficacy against insects.
In November 2006, BASF sold its global Terbufos insecticide business to American AMVAC (American Vanguard Corporation). [14] Organophosphate poisoning is not common in the developed world. Most cases of terbufos poisoning occur in the developing world, where protection against pesticides is scarce, but compounds such as terbufos are widespread ...
Assignment to a toxicity class is based typically on results of acute toxicity studies such as the determination of LD 50 values in animal experiments, notably rodents, via oral, inhaled, or external application. The experimental design measures the acute death rate of an agent.
Chlorpyrifos (CPS), also known as chlorpyrifos ethyl, is an organophosphate pesticide that has been used on crops, and animals in buildings, and in other settings, to kill several pests, including insects and worms. It acts on the nervous systems of insects by inhibiting the acetylcholinesterase enzyme.
Profenofos is an organophosphate insecticide. It is a liquid with a pale yellow to amber color and a garlic-like odor. [1] It was first registered in the United States in 1982. [3]: 1 As of 2015, it was not approved in the European Union. [4]
Phosphamidon is an organophosphate insecticide first reported in 1960. [ 3 ] [ 2 ] It acts as a cholinesterase inhibitor . The commercial product typically exists as a mixture of 70% ( Z )- isomer and 30% ( E )-isomer.
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.
