WebPhosphine (PH 3) is a toxidrome-spanning chemical that is widely used as an insecticide and rodenticide. Exposure to PH 3 causes a host of target organ and systemic effects, … WebAcute toxicity occurs primarily by the inhalation route when aluminum phosphide decomposes into the toxic gas, phosphine. The human median lethal dose for aluminum phosphide has been reported to be 20 mg/kg. Rated as super toxic: probable oral lethal dose is less than 5 mg/kg or less than 7 drops for a 70 kg (150 lb.) person. (EPA, 1998)
