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)

Phosphine inhibits cytochrome c oxidase, preventing mitochondrial oxidative phosphorylation. This non-competitive inhibition prevents cellular respiration and leads to multi-organ dysfunction. Phosphine can also react with hydrogen peroxide to form the highly reactive hydroxyl radical, which can cause lipid peroxidation. (A291, A292)

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.
