Chlorpyrifos
Chlorpyrifos
Chlorpyrifos (pronounced: klor-PEER-ih-fos) is a crystalline organophosphate pesticide that is commonly used in agriculture to control a variety of insects. It was first registered for use in the United States in 1965 and is sold under many brand names, including Dursban and Lorsban.
Etymology
The term "chlorpyrifos" is derived from the chemical compound's systematic name, which is O,O-diethyl O-3,5,6-trichloropyridin-2-yl phosphorothioate. The name is a combination of the Greek words for "green" (chloros), "fire" (pyr), and "bearing" (phoros), referring to the compound's appearance and its use as a pesticide.
Usage
Chlorpyrifos is used to control many different kinds of pests, including termites, mosquitoes, and roundworms. It is used in settings such as golf courses, greenhouses, and in non-structural wood treatments such as utility poles and fence posts. It is also registered for direct use on turkeys and cauliflower.
Health Effects
Exposure to chlorpyrifos can cause a range of health effects, from mild effects such as headaches and dizziness, to more serious effects such as seizures and paralysis. It can also affect the respiratory system, the cardiovascular system, and the nervous system.
Regulation
In the United States, the Environmental Protection Agency (EPA) regulates the use of chlorpyrifos. In 2015, the EPA proposed to revoke all food residue tolerances for chlorpyrifos, but this proposal was not finalized.
