Dichlorvos
Health Effects
EPA's Integrated Risk Information System classifies Dichlorvos as: B2; probable human carcinogen. EPA's stated basis: "Significant increases in forestomach tumors in female and male B6C3F1 mice and leukemias and pancreatic acinar adenomas in Fischer 344 rats. Supporting evidence included observation of tumors at other sites in the rat and observation of mutagenicity for both dichlorvos and a major metabolite dichloroacetaldehyde. A structurally related material, dichloropropene, also induces forestomach tumors in rodents." EPA has not set a federal drinking-water limit (MCL or MCLG) for Dichlorvos; IRIS assesses a chemical's toxicity, not the amount permitted in tap water.
