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
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.

This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
