Materials and methods
- Principles of method if other than guideline:
- Atmospheric saturation was obtained by placing 1.36 ml of the sample in an airtight twenty-litre chamber and allowing 24h for evaporation. The chamber was then momentarily opened to permit the quick insertion of mice. Exposure was terminated 1 h later and the animals were observed for 7 days.
- GLP compliance:
- no
- Test type:
- other: inhalation hazard test

Results and discussion
Effect levels
- Sex:
- male
- Dose descriptor:
- LC0
- Effect level:
- > 1.88 mg/m³ air
- Exp. duration:
- 1 h
- Remarks on result:
- other: inhalation hazard test
- Mortality:
- No mortality.
