Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Sediment toxicity
Administrative data
Link to relevant study record(s)
- Endpoint:
- sediment toxicity: long-term
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Justification for type of information:
- According to Annex X, Column 2, of REACH long-term toxicity testing shall be proposed by the registrant if the results of the chemical safety assessment indicates the need to investigate further the effects of the substance and/or relevant degradation products on sediment organisms. The chemical safety assessment did not identify any concern regarding the toxicity of the substance or its degradation products to the aquatic environment, it is therefore not considered relevant to perform a long-term toxicity study to the aquatic environment.
In addition Guidance R.7b: Endpoint specific guidance (Version 3.0 - February 2012) indicates a log Kow of ≥3 as a trigger value for assessing the effects of a substance to sediments. The purpose of the octanol-water partition coefficient is to determine the distribution of nonpolar organic compounds between water and natural solids (e.g. sediments) or organisms and is therefore not relevant for inorganic substances.

Additional information
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.
