Justification for type of information:
In accordance with section 1 of REACH Annex XI (testing does not appear scientifically necessary), the short-term toxicity to sediment organisms (required in section 9.5.1.) does not need to be conducted as 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. The available data is adequate for classification and labelling purposes and PBT assessment is not required for inorganic substances so no further testing is required. Furthermore, any ionic metal leaching out of the substance in environmental conditions is predicted to bind strongly to soil and sediments. On this basis the bioavailable concentration of manganese from the substances to terrestrial organisms is predicted to be much less than the background concentration of manganese in European soils (428.6 mg Mn/kg according to “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).
