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.
