Toxicity Profile
Route of ExposureInhalation
Mechanism of ToxicityArsine enters the bloodstream and crosses the alveolo-capillary membrane into red blood cells. Here it preferentially binds to hemoglobin and is oxidized to an arsenic dihydride intermediate and elemental arsenic, both of which are hemolytic agents. Arsine also depletes the reduced glutathione content of the red blood cells, resulting in the oxidation of sulfhydryl groups in hemoglobin and red cell membranes. These effects produce membrane instability, resulting in hemolysis. Arsine may also inhibit catalase, which leads to the accumulation of hydrogen peroxide. This destroys red cell membranes and may contribute to arsine-induced conversion of Fe+2 to Fe+3, which also impairs oxygen transport. (3)
MetabolismArsine is gradually converted to arsenite (As3+), then methylated into monomethylarsonic and dimethylarsinic acids. It is primarily excreted in the urine. (1)
Toxicity ValuesLD50: 2.5 mg/kg (Intraperitoneal, Mouse) (2) LC50: 20 ppm over 1 hour (Inhalation, Rat) (5)
Lethal Dose3 ppm for an adult human.
Carcinogenicity (IARC Classification)1, carcinogenic to humans. (4)
Uses/SourcesExposure to arsine usually occurs in an industrial setting, as it is often produced as a byproduct during the smelting and refining of metals. It is also used in the manufacture of semiconductors and crystals for fiberoptics and computer chips.
Minimum Risk LevelChronic Inhalation: 0.016 mg/m3 (6)
Health EffectsArsine exposure causes haemolytic anaemia, polyneuropathy, hypotension, and damage to the lungs, kidneys, liver, nervous system, heart, and blood-forming organs. (3)
SymptomsThe first signs of arsine exposure are difficultly breathing, headaches, vertigo, nausea, vomiting, abdominal pain, skin discoloration, and haemoglobinuria. (3)
TreatmentThere is no antidote for arsine. Treatment is symptomatic and consists of measures to support respiratory, vascular, and renal function. Whole blood transfusions may be effective if significant haemolysis has occurred. (3)
