Results and discussion
Effect levels
- Sex:
- male
- Dose descriptor:
- LC50
- Effect level:
- 329.6 mg/kg bw
- Based on:
- element
- 95% CL:
- >= 308.8 - <= 350.4
- Remarks on result:
- other: 329.6 mg/kg bw Mn corresponds to 329.6 x 389.1/55 = 2332 mg EDTA-MnNa2 per kg bw
Applicant's summary and conclusion
- Conclusions:
- The test material, a 1:1 mixtrure of MnSO4.H2O and EDTA-H2Na2/EDTA-Na4 was not acutely toxic via the ip route.
- Executive summary:
In acute study in Swiss mice both MnSO4.H2O and a 1:1 mixture of MnSO4.H2O and EDTA-Na4 were tested via a single intraperitoneal injection. The animals were observed for 30 days. The LD50 of the 1:1 mixture (resulting in EDTA-MnNa2) turned out to be 329.6 mg Mn per kg bw corresponding to 2332 mg EDTA-MnNa2 per kg bw. On a molar basis EDTA-MnNa2 was 7.5 times less toxic than the corresponding salt MnSO4.H2O, on a mg/kg bw basis EDTA-MnNa2 was 19 times less toxic.
