Description of key information

The EC50 for growth rate inhibition (72h-ERC50) exceeded 100 mg/L. Based on extrapolation a value of 113 mg/L was calculated (95% confidence interval ranging from 108 to 120 mg/L).

The EC50 for yield inhibition (72h-EYC50) was 41 mg/L with a 95% confidence interval ranging from 36 to 46 mg/L.

The 72h-NOEC for both growth rate inhibition and yield inhibition was 10 mg/L.

Key value for chemical safety assessment

EC50 for freshwater algae:
100 mg/L
EC10 or NOEC for freshwater algae:
10 mg/L
