Description of key information
In accordance with column 2 of Annex X of the Regulation (EC) No 1907/2006 REACH concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), the study does not need to be conducted, if no considerable exposure of sediment organisms is to be expected.
The test substance is not supposed to be directly applied to sediment and an indirect exposure to sediment is unlikely since the substance is readily biodegradable. For substances being considered as „readily biodegradable“, it can be assumed that they will be biologically degraded within the STP-process. In special cases, if the substance is not entering the STP-process but is readily biodegradable, it can be assumed that it will be rapidly biological degraded in the surface water. In both cases, a transfer to the sediment compartment is unlikely. As a consequence, no tests on sediment organisms are provided.
No adequate data available (not necessary).

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.
