Chemical compound

Tetrachlorvinphos is an organophosphate insecticide used to kill fleas and ticks.

History

Tetrachlorvinphos was initially registered for use in the United States in 1966 by the U.S. Department of Agriculture. Tetrachlorvinphos was originally registered for use on various food crops, livestock, pet animals, and in or around buildings. The crop uses were voluntarily canceled from product registrations in 1987. In 2014, the Natural Resources Defense Council (NRDC) filed lawsuits against the United States Environmental Protection Agency (EPA) seeking EPA to respond to NRDC’s petitions to ban tetrachlorvinphos in common pet flea treatment products.

Human health hazards

Symptoms of exposure to this material include increased perspiration, nausea, lachrymation, salivation, blurred vision, diarrhea, pulmonary edema, respiratory embarrassment and convulsions. The chemical material may be absorbed through the skin and is a lachrymator. It is a cholinesterase inhibitor and is a positive animal carcinogen.

Chemical properties

The substance is insoluble in water. Flash point data are not available for this chemical; however, it is probably combustible. Tetrachlorvinphos is slowly hydrolyzed in neutral and aqueous acidic media. Is rapidly hydrolyzed in alkaline media.
