概要
Gallium phosphide is a phosphide of gallium. It is a semiconductor and optical material that is used for manufacture of low and standard brightness red, orange, and green light-emitting diodes. Metal phosphides are hydrolysed to phosphine upon contact with water or stomach acid. Phosphine is a colorless, flammable, explosive, and toxic gas. (L980, L985)

毒性情報
TreatmentAs there is no antidote for phosphine poisoning, treatment is mainly symptomatic. Artificial respiration, gastric lavage, and/or administration of activated charcoal may be necessary. (L982)
Health Effects
Inhalation of phosphine may cause severe pulmonary irritation leading to acute pulmonary oedema, cardiovascular dysfunction, CNS excitation, coma and death. Gastrointestinal disorders, renal damage and leukopenia may also occur. Chronic exposure to phosphine can result in anemia, bronchitis, gastrointestinal effects, and visual, speech and motor problems. (L980, L982)
化学と産業
薬理情報
Metabolism/Metabolites
Phosphine and metal phosphides may be absorbed following ingestion or inhalation, then distribute to the nervous system, liver, and kidney. In the body, metal phosphides are hydrolysed to phosphine, and phosphine is oxidized to hypophosphite and phosphite. Metabolites are excreted in the urine, while unchanged phosphine is exhaled. (L982)
