Description of key information

The adsorption-desorption behaviour cannot be tested due the insolubility of niobium.

Key value for chemical safety assessment

Additional information

The adsorption-desorption study according to OECD TG 106 is technically not feasible. Due to the high insolubility of niobium in water analytical measurements cannot be performed with sufficient accuracy.
