Useful:

• Chemical Classes: Metals -> Arsenic Compounds, Inorganic
• Canonical SMILES: O=[As]O[As]=O
• Inhalation Risk: Evaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.
• Effects of Short Term Exposure: The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. The substance may cause effects on the blood, cardiovascular system, nervous system and liver. Inhalation may cause lung oedema. Exposure could cause death. The effects may be delayed. Medical observation is indicated.
• Effects of Long Term Exposure: Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the bone marrow (hematopoietic changes), cardiovascular system, central nervous system, peripheral nervous system, kidneys and liver. This may result in anaemia and impaired functions. This substance is carcinogenic to humans. Causes toxicity to human reproduction or development.
