Additional information
Aquatic
A standard acute toxicity study with Daphnia was conducted as a limit test at 100% v/v saturated solution (equivalent to 0.022 mg/l) and showed no effects. Therefore the 48 Hour EC50 was greater than 0.022 mg/l, and the NOEC was 0.022 mg/l. A standard acute toxicity study with fish was conducted withMn3O4as a limit test at 100% v/v saturated solution and showed no effects. Therefore the 96 Hour LC50 was greater than 100 %v/v and the NOEC was 100 %v/v (equivalent to 0.022 mg/l). Similar results were obtained in a standard chronic limit test study on Algae, resulting in 72h EC50 > 100% v/v saturated solution, and NOEC = 100% v/v saturated solution. An 8 day chronic study on Daphnia gave NOEC = 33% v/v saturated solution. It should be noted that these values are much lower than the background concentration of manganese in European environments (15.9 µg Mn/L in surface water; “Probabilistic Distribution of Manganese in European Surface Water, Sediment and Soil and Derivation of Predicted Environmental Concentrations (PEC)”, Parametrix, 2009 and supported by GEMAS data) and hence have very limited relevance for assessment of any potential risk from Mn3O4Sediment
No experimental data on sediment toxicity exist. The data are not requiredas the hazard assessment performed during the chemical safety assessment concludes that the substance is not classified and is of no immediate concern to the environment.PNEC sediment is calculated by the equilibrium partitioning method.
It should be noted that this value is considerably lower than the background concentration of manganese in European environments (452 mg/kg in sediment; “Probabilistic Distribution of Manganese in European Surface Water, Sediment and Soil and Derivation of Predicted Environmental Concentrations (PEC)”, Parametrix, 2009 and supported by GEMAS data) and hence has little relevance for assessment of any potential risk from Mn3O4
Terrestrial
No experimental data on terrestrial toxicity exist. The data are not requiredas the hazard assessment performed during the chemical safety assessment concludes that the substance is not classified and is of no immediate concern to the environment.PNEC soil is calculated by the equilibrium partitioning method.
It should also be noted that this value is considerably lower than the background concentration of manganese in European environments (428.6 mg/kg in soil; “Probabilistic Distribution of Manganese in European Surface Water, Sediment and Soil and Derivation of Predicted Environmental Concentrations (PEC)”, Parametrix, 2009 and supported by GEMAS data) and hence has little relevance for assessment of any potential risk from Mn3O4
STP
No effects on sewage sludge were observed in a standard 3hr study on Mn3O4. Hence the NOEC for Mn3O4is 1000mg/l.Conclusion on classification
