EPA Sets New Restrictions on Phosphine Fumigants to Reduce Poisonings

(Beyond Pesticides, April 8, 2010) The U.S. Environmental Protection Agency (EPA) is requiring new restrictions on aluminum and magnesium phosphide products in an attempt to better protect people, especially children, from dangerous exposures. The new restrictions prohibit all uses of the products around residential areas and increase buffer zones for treatment around non-residential buildings that could be occupied by people or animals from 15 feet to 100 feet. Human exposure to these toxic chemicals, though slightly minimized, would nevertheless continue because of their continued availability for use on athletic fields and playgrounds, around non-residential buildings, and in agricultural production. Phosphide fumigants are known to be highly acutely toxic when ingested or inhaled. Symptoms of mild to moderate acute exposure include nausea, abdominal pain, tightness in chest, excitement, restlessness, agitation and chills. Symptoms of more severe exposure include diarrhea, cyanosis, difficulty breathing, pulmonary edema, respiratory failure, tachycardia (rapid pulse) and hypotension (low blood pressure), dizziness and/or death. Aluminum and magnesium phosphide fumigants are used primarily to control insects in stored grain and other agricultural commodities. They also are used to control burrowing rodents in outdoor agricultural and other non-domestic areas. The fumigants are restricted to use by specially trained pesticide applicators. […]
