Description of key information
Since no effects were observed, a NOEC cannot be derived and the effect concentrations causing a 50% effect were estimated to be higher than 1000 mg/kg DW.
Key value for chemical safety assessment
Additional information
The long-term toxicity (assessed by reproduction) of the test item to sediment organisms (Lumbriculus variegatus) was assessed according to the OECD Guideline 225 for a duration of 28 days. According to the preliminary test, worms were exposed to 62.5, 125, 250, 500 and 1000 mg/kg DW of the test item.
No mortality and no effects on reproduction and on biomass increase were observed at all the concentrations tested.
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.
