Conclusion on classification
Studies performed with the substance
In 3 short-term studies performed in accordance with the current OECD guidelines, up to a concentration present in a 0.45 μm filtered solution prepared at a loading rate of 100 mg/L, the substance did not induce visible or lethal effects in carp, did not induce acute immobilisation of Daphnia magna and did not reduce the growth rate of Pseudokirchneriella subcapitata.
Metals strategy
The substance is an inorganic metal substance. Consequently any classification based on the metals strategy presented in the Guidance on the Application of the CLP criteria should also be investigated. Following the guidance, consideration should be given to the level of the metal ion which may be present in solution following the addition of the metal compound. In case of this particular substance there are three metals to consider, Ca, Sb and Mn. The acute toxicity values for calcium ion are greater than 100 mg/L. Based on this information, any classification based on Mn and/or Sb ion needs to be investigated only. The rate and extent of transformation of these 2 elements from the substance must be considered.
The water solubility data show that the concentration of Sb and Mn in a with the substance saturated water phase is below 1 µg/L (the detection limit). From the ecotoxicity studies followed that the concentration of Sb and Mn remained low (below 10 µg/L) and constant over time (<1 µg Mn/L at t=0 up to 2.22 µg Mn/L at t=48 hours and 5.74 µg Sb/L at t=0 up to 7.23 µg Sb/L at t=96 hours). It must be noted that Sb and Mn are measured in these studies as part of the substance, in their non-dissociated form, as well as dissociated ions, if applicable, because the used analytical method (ICP-MS) does not distinguishes their forms as present in water. The measured Sb and Mn concentrations may therefore also origin from the substance.
Based on this supportive data, showing that the rate and extent of transformation of these metal ions from the substance is low (and slow), if any, it is not considered needed to obtain more information, by following the Transformation/Dissolution Protocol. It is concluded that there is enough information to assess the environmental classification of the substance.
Conclusion
Based on all the available information, the substance does not need to be classified for the environment and performing a study with the substance using the Transformation/Dissolution Protocol is not regarded needed. The rate and extent of transformation of the relevant ions Mn and Sb from the substance has been shown to be negligible, if any, based on the already available information.Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
