Visual disturbances after experimental human exposure to triethylamine.
British Journal of Industrial Medicine
|December 1, 1985
Summary
Exposure to triethylamine (TEA) at 18 mg/m3 for eight hours caused visual disturbances and corneal swelling in volunteers. These effects resolved within hours but pose risks for workplace and traffic safety.
Area of Science:
- Occupational Health
- Toxicology
- Ophthalmology
Background:
- Triethylamine (TEA) is an industrial chemical with potential health effects.
- Understanding the ocular and visual impacts of TEA exposure is crucial for worker safety.
Purpose of the Study:
- To investigate the visual and ocular effects of airborne triethylamine exposure in human volunteers.
- To determine the concentration and duration of TEA exposure that elicits adverse effects.
Main Methods:
- Two volunteers were exposed to controlled airborne concentrations of triethylamine.
- Subjective visual symptoms and objective corneal changes were assessed.
Main Results:
- Exposure to 18 mg/m3 of TEA for eight hours induced subjective visual disturbances like haze and halos.
- Objective findings included corneal edema, which resolved within hours post-exposure.
Conclusions:
- Airborne triethylamine can cause transient visual disturbances and corneal edema.
- These effects may impair vision, increasing accident risk in occupational and traffic settings after exposure cessation.
