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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water and sediment: simulation tests
Administrative data
Link to relevant study record(s)
Description of key information
The performance of simulation tests for biodegradation in water and sediment is scientifically unjustified.
Regulation (EC) No 1907/2006 (REACH), Annex IX, Sect. 9.2.1.2 and Sect. 9.2.1.4, Col. 2, states as follows:
“9.2.1.2/9.2.1.4: The study need not to be conducted:
– the substances is highly insoluble in water; or
– the substance is readily biodegradable.
and
- if the substance is readily biodegradable; or
– if direct and indirect exposure of sediment is unlikely."
The test substance is practically insoluble in water. In addition, low exposure is guaranteed, as no sludge application from STP on soil will be done and aerial deposition is negligible. Thus, simulation testing for biodegradation in water and sediment was considered not scientifically justified.
Key value for chemical safety assessment
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.
