Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Sediment toxicity is considered not to be relevant for assessment since tantalum is not exposed to this compartment and the substance is in addition not considered to be environmentally toxic.
Key value for chemical safety assessment
Additional information
Elemental tantalum is insoluble in water and thus not bioavailable, it is physiologically inert and harmless. Due to the low bioavailability the bioaccumulation potential is negligible and tantalum metal is considered not to cause any hazardous effects. Furthermore, entry into the environment, from industrial use, is unlikely to occur. Thus, long-term testing with sediment organisms is considered to be scientifically unjustified.
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.
