Useful:

Chemical Classes:Toxic Gases & Vapors -> Acids, Inorganic
Canonical SMILES:OP(=O)(O)O
Inhalation Risk:A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20 °C.
Effects of Short Term Exposure:The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation may cause asthma-like reactions (RADS). Exposure could cause asphyxiation due to swelling in the throat. Inhalation of high concentrations may cause lung oedema, but only after initial corrosive effects on the eyes and the upper respiratory tract have become manifest. Inhalation of high concentrations may cause pneumonitis.
Effects of Long Term Exposure:The substance may have effects on the upper respiratory tract and lungs. This may result in chronic inflammation and reduced lung function . Mists of this strong inorganic acid are carcinogenic to humans.
