Key value for chemical safety assessment

Additional information

The chemical safety assessment according to Annex I indicates that it is not necessary to conduct the simulation test on ultimate degradation in surface water and the sediment simulation test, or to identify degradation products. Sediment simulation testing is not considered necessary because the risk characterisation ratios (RCRs) for the sediment compartment, based on the assumption that the substance is not biodegradable, are <1.
