Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
No toxic effect on fish is expected since niobium is insoluble in water.
Key value for chemical safety assessment
Additional information
In accordance with column 2 of Annex VII and VIII of Regulation (EC) No 1907/2006, short-term studies for the aquatic ecotoxicity do not need to be conducted if there are mitigating factors indicating that aquatic toxicity is unlikely to occur, for instance if the substance is highly insoluble in water. However, a study on the long-term toxicity according to OECD guideline 210 is ongoing for niobium metal to fulfill the demands that are described in the ECHA decision (Communication number CCH-D-2114517391-56-01/F). This information will be submitted later based on ECHA communication/decision number TPE/CCH/SEV-CCH-D-2114517391-56-01/F. Reasons for this delay are summarized in the attached status report (Status of Aquatic Toxicity Tests (OECD 201, 210 and 211) with Niobium metal powder).
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.
