Methyl Parathion: an Organophosphate Insecticide Not Quite Forgotten
Reviews on Environmental Health, 2006Methyl parathion (MP), a toxic organophosphate insecticide approved for outdoor use only, is classified by the World Health Organization (WHO) as a Category Ia (extremely toxic) and by the United States Environmental Protection Agency (U.S. EPA) as a Toxicity Category I (most toxic) insecticide. In several U.S. states in the late 1980s and early 1990s,

Sorption-desorption characteristics of methyl parathion by clays
Archives of Environmental Contamination and Toxicology, 1979Methyl parathion (O,O-dimethyl O-(4-nitrophenyl) phosphorothioate) adsorption was studied on montmorillonite, kaolinite, halloysite, natural zeolite, ion exchange resins and calcium carbonate. Methyl parathion was highly adsorbed by montmorillonite, followed by zeolite, and very little adsorption was obtained on kaolinite and halloysite.

Pharmacokinetics and pharmacodynamics of methyl parathion.
Zhonghua yi xue za zhi = Chinese medical journal; Free China ed, 2002Methyl parathion and other organophosphorus insecticides are widely used in agriculture. Poisonings to this class of compounds are common and exerted primarily through inhibition of acetylcholinesterase. Methyl parathion became a major health concern when it was illegally sprayed in private homes.

DNA damaging activity of methyl parathion.
Research communications in chemical pathology and pharmacology, 199114C-methyl parathion was covalently bound to DNA, RNA and proteins of various rat and mouse organs 22 hr after i.p. injection. Covalent binding index (CBI) to liver DNA was low in both species and typical of weak initiators. The labelings of RNA and proteins from different organs of both species was slightly higher than DNA binding. No interaction with
