Applicant's summary and conclusion
- Conclusions:
- The acute inhalation toxicity of acetic acid in the rat, following a 4 hour exposure, was > 16000ppm, equivalent to > 40 mg/L
- Executive summary:
A group of 6 rats was exposed to a concentration of 16,000 ppm acetic acid for 4 hours and was then observed for up to 14 days. One out of 6 rats died within 14 days of exposure. The acute inhalation toxicity of acetic acid in the rat, following a 4 hour exposure, was > 16000ppm, equivalent to > 40, 000 mg/m3.
