Applicant's summary and conclusion
- Interpretation of results:
- other: Not classified
- Conclusions:
- The acute inhalation toxicity dose (LC50) was considered to be 550000 mg/m3, when rats were exposed with test chemical via inhalation route for 30 min.
- Executive summary:
The acute inhalation toxicity study was conducted by using test chemical in rats at the concentration of 550000 mg/m3. 50% mortality was observed at 550000 mg/m3. Therefore, LC50 was considered to be 550000 mg/m3, when rats were treated with test chemical by inhalation for 30 min exposure.
