Applicant's summary and conclusion
- Conclusions:
- The i.p. LD 50 values in rats were found to be 254 mg/kg (50% Na3NTA) and 446 mg/kg (20% Na3NTA). No unusual symptoms were observed in any ot the animals following injection. All surviving animals appeared normal 24 h after dosing. I.p. injection is not considered relevant for human hazard assessment.
