Description of key information
Tantalum is insoluble in water and not bioavailable to aquatic species. As an inorganic substance without any bioavailability, Ta cannot be metabolised. Under physiological conditions, Ta metal cannot be absorbed via skin or the gastrointestinal tract. Even in the case of administration via the oral route and ingestion, Ta will be eliminated via faeces without prior absorption (see also IUCLID section 7.1). Thus, there is no potential for bioaccumulation and testing is scientifically unjustified.
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.

This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
