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
