Applicant's summary and conclusion
- Interpretation of results:
- other: Not classified
- Conclusions:
- The acute dermal LD50 value was considered to be 2190 mg/kg bw, when rabbits were treated with the given test chemical by dermal route.
- Executive summary:
Acute dermal toxicity study of the given test chemical was conducted in rabbits at the dose concentration of 2190 mg/kg bw.
The animals were observed for mortality. 50% mortality was observed at 2190 mg/kg bw in treated animals.
Hence, the LD50 value was considered to be 2190 mg/kg bw, when rabbits were treated with the given test chemical by dermal route.
