Sediment toxicity
Administrative data
- Endpoint:
- sediment toxicity: long-term
- Type of information:
- experimental study planned
- Justification for type of information:
- In accordance with the ECHA Guidance R.7b, the equilibrium partitioning method is not applicable to poorly water soluble substances for which no effects are observed in aquatic studies. For such substances, at least one sediment study has to be performed for a more realistic sediment risk assessment.
As the registered substance was tested for short-term and long-term hazards to fish, aquatic invertebrates and algae and no significant effects were detected, the EPM is not a viable method to derive sediment PNECs. Therefore, one long-term toxicity to sediment organisms is proposed. As the substance has a log Kow value greater than 5 and log Koc > 4, it is expected to be strongly adsorbing. Consequently, a long-term toxicity study on a sediment-dwelling organism (Lumbriculus variegatus - OECD 225) is considered more relevant.

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.
