Pesticides. Today, organophosphates make up about 50% of the killing agents in chemical pesticides. Organophosphate pesticides (OPPs), like some nerve agents, inhibit acetylcholinesterase, which is broadly essential for normal function in insects, but also in humans and many other animals.

Organophosphate insecticides have been widely used for >30 years to protect agricultural and horticultural crops, for public hygiene and to control arthropod pests in gardens and homes.

1 In addition, some organophosphates have been licensed as human or veterinary medicines—for example, in the treatment of head lice and in the prevention of scab and other ectoparasitic infestations in sheep.

‘The Edinburgh-based Institute of Occupational Medicine has reported nerve damage among farm workers exposed to organophosphates.’ ‘Scientists from Manchester University studied an enzyme found in blood which is responsible for breaking down an organophosphate used in sheep dip.’.

An infusion can. Organophosphate and Carbamate Insecticides. Poisoning by organophosphate or carbamate insecticides is common and often severe. These two groups of compounds account for a large percentage of the childhood deaths from ingested poisons each year.

Absorption can occur through the gastrointestinal tract, the lungs, and, for most compounds, the skin. 43 CHAPTER 5 Organophosphate Insecticides Organophosphates (OPs) are a class of insecticides, several of which are highly toxic.

Until the 21st century, they were among the most widely used insecticides available. Thirty-six of them are presently registered for use in the United States, and all can.

Organophosphate insecticides are highly toxic to insects but are relatively less so to humans and domestic animals. Although specific organophosphates, such as triorthocresyl phosphate, nipafox, and trichlorofon compounds, are obviously neurotoxic, the situation.
