Description of key information
Significant inhibitory effects were determined for growth rate and yield at test item concentrations of 0.298 mg/L (nominal) and 0.0563 mg/L (actual) and above. The overall LOEC was determined to be 0.298 mg/L (nominal) and 0.0563 mg/L (actual), the corresponding NOEC was not determinable. The EC10-value for growth rate (ErC10) was determined to be 1.64 mg/L (nominal) and 0.401 mg/L (actual). The EC10-value for yield (EyC10) was 0.193 mg/L (nominal) and 0.0407 mg/L (actual).The EC50-value for growth rate (ErC50) was determined to be 10.7 mg/L (nominal) and 2.45 mg/L (actual). The EC50-value for yield (EyC50) was 2.32 mg/L (nominal) and 0.516 mg/L (actual).
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 2.45 mg/L
- EC10 or NOEC for freshwater algae:
- 0.401 mg/L
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.
