Description of key information
Relevant distribution into the sediment compartment and exposure of sediment organisms is not expected.
Key value for chemical safety assessment
- EC50 or LC50 for marine water sediment:
- 875.47 mg/kg sediment dw
Additional information
Since the physicochemical data indicate that the substance is not very adsorptive or bioaccumulative, a relevant distribution into the sediment compartment and a considerable exposure of sediment organisms is not expected.
Supporting
The sediment toxicity was tested in a short term sediment toxicity study according to US EPA 600/4-85/013. The test organisms Corophium volutator was collected from a site in the Bay of Suckquoy, near Sebay farm in Orkney and acclimated to laboratory conditions for seven days prior to testing. The exposure time was 10 days. The test substance exhibited a 10 day LC50 value of 875.47 mg/kg sediment dw.
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.
