Applicant's summary and conclusion

Interpretation of results:
other: Not classified
Conclusions:
The acute inhalation toxicity dose (LC50) value was considered to be 20000 mg/m3, when rats was treated with the given test chemical via inhalation route for 8 hours exposure.
Executive summary:

Acute inhalation toxicity study was conducted in rats using the given test chemical at the dose concentration of 20000 mg/m3 via inhalation route for 8 hours exposure.

Animals were observed for mortality. 50% mortality observed at 20000 mg/m3.

Hence, the LC50 value was considered to be 20000 mg/m3, when rats was treated with the given test chemical via inhalation route for 8 hours exposure.
