Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Tantalum metal is not considered to cause toxic effects in birds.
Key value for chemical safety assessment
Additional information
As the test substance is not classified as toxic or harmful to mammals, the substance is also not considered to cause toxic effects in birds. Elemental tantalum is physiologically inert and harmless.
Additionally, due to the low bioavailability (tantalum is insoluble) the bioaccumulation potential is negligible and thus the test material is considered not to cause any hazardous effects to predators like birds. Thus, a study with birds is scientifically unjustified. Taking also in consideration animal welfare reasons, testing with birds will be omitted.
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.
