Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Endpoint:
- sediment toxicity: long-term
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Justification for type of information:
- In accordance with Column 2 of REACH Annex X, information requirement section 9.5.1, this study does not need to be conducted as the chemical safety assessment concluded that there is no hazard. The assessment indicated that there is low potential for the substance to adsorb to sediment. The Kow is -0.19 and as such it is consiered hydrophillic. It is not a PBT or vPvB substance. A number of sediment biodegradation studies show that the the test material is degraded in both aerobic and anaerobic sediments. In particular, a sediment biodegradation study (Bieber and Krohn, 1991) showed that the microorganisms involved in the breakdown of the herbicide containing the registered substance used the solvent (methanol) or the active ingredient as a carbon source. Furthermore, Williams et al. (2003) showed that the microbial community adapted relatively quickly to degrade the test material. As such it is considered unnecessary to conduct further testing.

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.
