Visual disturbances after experimental human exposure to triethylamine.
Two volunteers were exposed to various airborne concentrations of triethylamine. Levels of 18 mg/m3 for eight hours caused subjective visual disturbances (haze and halos) and objective corneal oedema. The effects faded within hours after the end of exposure. The visual disturbances are unpleasant and may cause accidents at work and in traffic after the end of work.
