- Conclusions:
- The LD50 was considered to be 2340 mg/kg bw, when male rat was treated with the given test chemical via oral route.
- Executive summary:
Acute oral toxicity test was conducted using the given test chemical in male rat at the concentration of 2340 mg/kg bw. 50% mortality was observed at 2340 mg/kg bw.
Hence, the LD50 was considered to be 2340 mg/kg bw, when male rat was treated with test chemical via oral route.
