Dioxathion, systematically known as p-dioxane-2,3-diyl ethyl phosphorodithioate, is an organophosphate pesticide. It is used as an insecticide on livestock and as an acaricide on citrus fruits, deciduous fruits and nuts. Dioxathion is an Extremely Hazardous Substance,it continues to see use in some other countries. It has been known to cause inhibition of the enzyme cholinesterase in rats, and it is recommended that people who have exposure to dioxathion regularly get their plasma and red blood cell cholinesterase levels assessed. Persons exposed to other chemicals which affect cholinesterase levels, e.g. other organophosphates or carbamates, may be at an increased risk. There are no known carcinogenic or reproductive effects, but long term exposure may result in nerve damage, poor motor coordination, and personality changes of anxiety, depression or irritability.
