Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The effects of the test item on the bacterivorous nematode Caenorhabditis elegans in a sediment system were determined in the year 2012. In this study the test item did not induce significant mortality of C. elegans at all test item concentrations after an exposure for 96 hours. Also, adult nematode fertility as well as nematode reproduction per inserted female test organism was not affected at all test item concentrations.
No reduction of growth was observed at all test item concentrations after four days of exposure to the test item compared to the control.
Thus, the Lowest Observed Effect Concentration (LOEC) concerning all test parameters was set at > 1000 mg test item/kg sediment dry weight. TheOverall No Observed Effect Concentration (NOEC) was determined to be 1000 mg test item/kg sediment dry weight. All effect levels given are based on the nominal concentrations of the test item.
Key value for chemical safety assessment
- EC10, LC10 or NOEC for freshwater sediment:
- 1 000 mg/kg sediment dw
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.
