Parathion

Parathion, also known as ethyl parathion, is a highly toxic organophosphate compound that is used as an insecticide and acaricide. It was originally developed by the German company IG Farben in the 1940s.

History

Parathion was first synthesized in 1944 by Gerhard Schrader, a chemist working for IG Farben. It was one of a series of organophosphate compounds that Schrader developed as potential nerve gases for use in World War II. After the war, these compounds were repurposed as insecticides and acaricides.

Uses

Parathion is used to control insects and mites on a wide variety of crops, including fruits, vegetables, and field crops. It is also used to control pests in home gardens and on ornamental plants.

Health effects

Exposure to parathion can cause a range of adverse health effects, including nausea, vomiting, abdominal pain, and diarrhea. In severe cases, it can cause seizures, respiratory failure, and death.

Environmental impact

Parathion is highly toxic to birds, fish, and bees. It can also contaminate water supplies and harm non-target insects and other wildlife.

Regulation

Due to its high toxicity and environmental impact, the use of parathion is heavily regulated in many countries. In the United States, the Environmental Protection Agency (EPA) has classified parathion as a Restricted Use Pesticide (RUP).
