Ethion (C9H22O4P2S4) is an organophosphate insecticide. Ethion is known to affect a neural enzyme called acetylcholinesterase and prevent it from working.

Review[edit]

Ethion was one of many substances that was approved for use based on data from Industrial Bio-Test Laboratories, which prompted the Food and Agriculture Organization and World Health Organization to recommend its reanalysis in 1982.[3]
