Dimethoate is a widely used organophosphorus (OP) insecticide applied to kill mites and insects systemically and on contact(1). It was introduced in the 1950s, originally patented by American Cyanamid(2), and is now produced by 39 companies around the world(3).s with all OPs, dimethoate is rapidly absorbed through the skin, and easily absorbed through the lungs(20). The population as a whole is not generally subject to exposure to dimethoate from air, water or food(21); however occupational exposure may occur during manufacture, formulation and use.
