Tetrachlorvinphos is anorganophosphateinsecticide used to killfleas andticks.[2]
Tetrachlorvinphos was initially registered for use in the United States in 1966 by theU.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.[5] In 2014, theNatural Resources Defense Council (NRDC) filed a lawsuit against theUnited States Environmental Protection Agency (EPA) seeking EPA to respond to NRDC's 2009 petition to ban tetrachlorvinphos in common pet flea treatment products.[6][7]
Symptoms of exposure to this material include increasedperspiration,nausea,lachrymation,salivation, blurred vision,diarrhea,pulmonary edema,respiratory depression andconvulsions. The chemical material may be absorbed through the skin and is a lachrymator. It is acholinesterase inhibitor and is a positive animalcarcinogen.[3]
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.[3]
