Description of key information
Key data: EC10 >1 mg/L (nominal for reproduction and immobilitsation effects); NOEC: 0.316 mg/L (nominal); LOEC: 1 mg/L (nominal)
Key value for chemical safety assessment
Additional information
The long-term toxicity test to aquatic invertebrates (Caspers & Müller, 1998) performed according to OECD 211 and GLP was rated with RL=2 (reliable with restrictions) and used as a key study. At test concentrations of 0.316 and 0.1 mg test item/L, significant effects could not be observed.
The EC10 value is estimated at >1 mg/L (nominal for reproduction and immobilitsation effects) as a mean reproduction of 92.3 % was observed at the highest tested concentration of 1 mg/L. The No Observed Effect Concentration (NOEC) and the Lowest Observed Effect Concentration (LOEC) were as follows:NOEC: 0.316 mg/L (nominal)
LOEC: 1 mg/L (nominal).
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.
