Conclusion on classification
No adverse effects could be demonstrated Daphnia magna and on the growth of Desmodesmus subspicatus after exposure to a saturated NbO solution for up to 48 h and 72 h, respectively. The tests were conducted under GLP and according to EC Directive 92/69/EC method C.2. and C.3, respectively. In both tests the saturated solutions were prepared at a nominal loading level of 100 mg/L in the respective test media, and were used in the tests after shaking for 24 h and subsequent filtration. The actual concentration of Nb in both test solutions was verified to be below 1 mg/L.
Therefore, it is concluded that the test substance is not toxic to freshwater algae and aquatic invertebrates. A classification for aquatic toxicity is not warranted.
This information is used in a read-across approach in the assessment of the target substance.
For details and justification of read-across please refer to the attached report in section 13 of IUCLID.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
