The study on biodegradation in water and sediment simulation tests shall be waived.

Key value for chemical safety assessment

Additional information

Based on REGULATION (EC) No 1907/2006, Annex VII, column 2 (section 9.2.1) and ECHA Endpoint Specific Guidance Chapter R.7B (Nov-2012, page 208), the simulation testing on ultimate degradation in surface water needs not be conducted if the substance is readily biodegradable. Study waived as ready biodegradability applies to the test item. Likewise sediment simulation testing needs not be conducted if the substance is readily biodegradable.
