Applicant's summary and conclusion

Interpretation of results:
Category 5 based on GHS criteria
Conclusions:
LD50 was considered to be 4800 mg/kg bw, when rats was treated with Acetohydroxamic acid (546-88-3) via oral route.
Executive summary:

In an acute oral toxicity study, rats were treated with Acetohydroxamic acid (546-88-3) at the concentration of 4800mg/kg bworally. 50% mortality was observed in treated rats at 4800 mg/kg bw. Therefore, LD50 was considered to be 4800 mg/kg bw, when rats was treated with Acetohydroxamic acid via oral route.
