Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- sediment toxicity: long-term
- Data waiving:
- exposure considerations
- Justification for data waiving:

- Justification for type of information:
- There is no concern for relevant exposure of sediment organisms to the test substance. As calculated by EUSES, if 2-EHMA is released into water, it mainly remains in the water and is predicted to partition only to a small degree into sediment. Therefore, the expected hazard to sediment organisms is low due to the level of ecotoxic potential derived from tests with aquatic organisms compared to the expected exposure concentration calculated by EUSES. Furthermore, data of structural analogues methyl methacrylate and the common metabolite methacrylic acid indicate low toxicity to sediment microorganisms. Moreover, 2-EHMA is readily biodegradable and was demonstrated experimentally to have no potential for bioaccumulation (BCF = 37). Therefore, it is not expected to persist in soil.

Applicant's summary and conclusion
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.
