Key value for chemical safety assessment
Acute toxicity: via oral route
Endpoint conclusion
- Dose descriptor:
- LD50
- Value:
- 2 000 mg/kg bw
Acute toxicity: via inhalation route
Endpoint conclusion
- Dose descriptor:
- LC50
- Value:
- 5 000 mg/m³
Additional information
Justification for classification or non-classification
The LD50 was greater than 2000 mg/kg for the oral route. The acute inhalation result from Mn3O4 (> 5000 mg/m3) shows no classification is justified. No dermal absorption is expected for an inorganic substance.
