Description of key information
The key value was derived from a study performed under GLP conditions and according to OECD 202. No immobilisation was observed throughout the study resulting in an 48-h EC50 for Daphnia magna of > 100 mg test item/L
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 100 mg/L
Additional information
The acute toxicity of the substance to the water flea Daphnia magna was investigated in a 48-hour static test (Parr, 2014) according to the OECD 202 guideline. This study was considered as key study for the PNEC derivation (K-score is 1). Daphnia magna were exposed to 100 mg/L of test substance during 48 hours. Analysis of the 100 mg/L test preparation at 0 and 48 hours showed measured concentrations of 97% and 95% of the nominal value respectively, so the results are based on nominal test concentrations. The results showed an 48-h EC50 >100 mg/L.
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).
