Endpoint:
biodegradation in water: sediment simulation testing
Data waiving:
study technically not feasible
Justification for data waiving:
other:
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
In accordance with REACH Annex XI section 2, 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 this endpoint is not technically feasible.

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) is not required as the substance is inorganic and hence biotic degradation cannot occur. Thus measurement of this endpoint is not technically feasible.

Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
In accordance with REACH Annex XI section 2, 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.

Description of key 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), are 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.

Key value for chemical safety assessment
