ACUTE EXPOSURE INFORMATION
- Gallium arsenide is poorly absorbed from the gastrointestinal tract. Acute toxicity is unlikely and has not been reported. Gallium arsenide components are used in the semiconductor industry and are unlikely to produce acute symptoms.
- Chronic toxicity is possible from occupational exposure, but has not been reported. Any anticipated toxicity would most likely be due to the arsenic component.
- Chronic health effects due to inorganic arsenic include: primarily cancers {i.e., lung cancer}, perforation of the nasal septum, laryngitis, pharyngitis, bronchitis, peripheral neuropathy, and encephalopathy.
- Dermatologic exposure to inorganic arsenic has resulted in hyperkeratosis of the palms and skin cancer.
- Under certain conditions arsine gas may be liberated from gallium arsenide.
- For further information on arsenic and arsine gas please refer to the ARSENIC or ARSINE managements.
