Description of key information

The EC50 for growth rate inhibition (72h-ERC50) was 26 mg/L with a 95% confidence interval ranging from 17 to 38 mg/L.

The EC50 for yield inhibition (72h-EYC50) was 16 mg/L with a 95% confidence interval ranging from 13 to 19 mg/L.

The 72h-NOEC for growth rate inhibition was 4.7 mg/L, based on both statistical significance and biological relevance.

The 72h-NOEC for yield inhibition was 1.6 mg/L based on statistically significance and 4.7 mg/L based on biologically significance.

Key value for chemical safety assessment

EC50 for freshwater algae:
26 mg/L
EC10 or NOEC for freshwater algae:
4.7 mg/L
