Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
Waiving argument:
In accordance with column 2 of REACH Annex X, the study on sediment organisms does not need to be conducted as direct and indirect exposure of the sediment compartment is unlikely.
A supporting argument is that for substances being considered as „readily“, it can be assumed that they will be completely biologically degraded within the STP process. Furthermore, for substances not passing the STP-process but being readily, it can be assumed that they will be also biological degraded in the surface water within a short time. PNECs for sediment organisms have been derived using the EPM method.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
