Description of key information

In accordance with column 2 of REACH Annex X, the long-term toxicity to sediment organisms study does not need to be conducted as the chemical safety assessment according to Annex I has not indicated a need to investigate further the effects of the substance and/or degradation products on sediment organisms.

Sediment effect values have been derived from a validated TLM-EqP modeling framework to provide additional data even though testing is not required. These data were considered reliable; however, were not used in the hazard assessment. The PNECs and hazard to sediment organisms was assessed by applying the equilibrium partitioning method (EqP) to the experimentally derived aquatic effect concentrations.
