Description of key information

The 72h-NOEC for growth rate inhibition was 100 mg/L when based on biological relevance and <10 mg/L when based on statistical significance.

The 72h-EC10 for growth rate inhibition (ERC10) was 82 mg/L with a 95% confidence interval ranging from 54 to 194 mg/L.

The 72h-EC50 for growth rate inhibition (ERC50) was >100 mg/L.

The 72h-NOEC for yield inhibition was 18 mg/L when based on biological relevance and <10 mg/L when based on statistical significance.

The 72h-EC10 for yield inhibition (EYC10) was 26 mg/L with a 95% confidence interval ranging from 5 to 40 mg/L.

The 72h-EC50 for yield inhibition (EYC50) was >100 mg/L.

Key value for chemical safety assessment

EC50/LC50 for freshwater algae:
100 mg/L
EC10, LC10 or NOEC for freshwater algae:
