Description of key information
An algal (Selenastrum capricornutum) study was performed with Glycidol. Selenastrum capricornutum were expopsed to Glycidol for a period of 96 hours. The study was carried out in accordance with ERL-C standard operating procedure with specified modifications as requested by OTS. The nominal concentrations used were: 500, 250, 125, 62.5, 31.25 mg/L. The 96-hour EC50 was 144.7 mg/L (based on nominal concentrations).
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 144.7 mg/L
Additional information
An algal (Selenastrum capricornutum) study was performed with Glycidol.Selenastrum capricornutum were exposed to Glycidol for a period of 96 hours. The study was carried out in accordance with ERL-C standard operating procedure with specified modifications as requested by OTS. The nominal concentrations used were: 500, 250, 125, 62.5, 31.25 mg/L. The 96-hour EC50 was 144.7 mg/L (based on nominal concentrations).
Based on the result above and as the substance is readily biodegradable, the substance 2,3-Epoxypropanol (Glycid) is not classified for toxicity to the aquatic environment according to Regulation (EC) No. 1272/2008 or Directive 67/548/EEC.
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.
