Parathion

Parathion (pronounced: /pəˈræθi.ɒn/), also known as ethyl parathion, is a highly toxic organophosphate compound that is used as an insecticide and acaricide.

Etymology

The term "parathion" is derived from the chemical name para-nitrophenyl diethyl thionophosphate.

Usage

Parathion is used in agriculture to control insects and mites on a variety of crops, including fruits, vegetables, and field crops. It is also used to control pests in home gardens and on ornamental plants. However, due to its high toxicity, its use is restricted in many countries.

Toxicity

Parathion is highly toxic to humans and animals. It inhibits the enzyme acetylcholinesterase, which is essential for normal nerve function. Symptoms of parathion poisoning include nausea, vomiting, abdominal pain, and in severe cases, seizures, respiratory failure, and death.
