Applicant's summary and conclusion
- Interpretation of results:
- other: Not classified
- Conclusions:
- The acute inhalation toxicity study in rat by using the test chemical was considered to be >1000 mg/m3.
- Executive summary:
The acute inhalation toxicity study was conducted by using the given test chemical in rats at the concentration of 1000 mg/m3. No mortality was observed at 1000 mg/m3.
Therefore, the LC50 was considered to be >1000 mg/m3, when rats were treated with test chemical by inhalation.
