Results and discussion
- Results:
- Human volunteers exposed to ethanethiol at 10 mg/m3 (4 ppm) 3 hours daily during 5 to 10 days produced effects that included a rise in the olfactory threshold and altered taste reaction to bitter and sweet substances; periodic nausea; irritation of mucous membranes of the lips, mouth, and nose; and a sensation of fatigue. Exposure at 1 mg/m3 (0.5 ppm) produced no unpleasant symptoms.
