Description of key information

No studies to investigate biodegradation in water and sediment have been conducted as the substance is inorganic so no degradation will occur.

Key value for chemical safety assessment

Additional information

In accordance with section 2 of REACH Annex XI, the simulation testing on ultimate biotic degradation in surface water (required in section 9.2.1.2) and sediment simulation testing (required in section 9.2.1.4), is not required as the substance is inorganic and hence biotic degradation cannot occur. Thus measurement of these endpoints is not technically feasible. Moreover, the identification of degradation products (required under section 9.2.3) does not need to be conducted as the substance is inorganic and hence neither biotic nor abiotic degradation will occur. There will therefore be no degradation products.
