Description of key information
The EC50 for growth rate inhibition (72h-ERC50) exceeded 84 mg/L, being the Time Weighted Average (TWA) concentration measured in the highest concentration tested.
The EC50 for yield inhibition (72h-EYC50) equalled a TWA concentration of 30 mg/L with a 95% confidence interval ranging from 27 to 33 mg/L.
The 72h-NOEC for growth rate inhibition was below a TWA concentration of 7.7 mg/L based on statistical significance or 29 mg/L when based on biological relevance.
The 72h-NOEC for yield inhibition was below a TWA concentration of 7.7 mg/L based on both statistical significance and biological relevance.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 84 mg/L
- EC10 or NOEC for freshwater algae:
- 29 mg/L
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
