Description of key information
Significantly different effects were observed between effects to growth rate and biomass. Based on geometric mean measured concentrations the ErC50 is 54.8 mg/l and the EbC50 is 7.0 mg/l
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 54.8 mg/L
- EC10 or NOEC for freshwater algae:
- 1 mg/L
Additional information
ErC50 values are used for CSA in compliance with the thresholds expressed in CLP (regulation 1272/2008).
The substance does not meet the criteria for classification as Acute Category 1.
Furthermore, the substance is not classified for Chonic Category 3 due to the rapid biodegradation observed in the ready biodegradation test, meaning that the substance does not meet the criteria for classification expressed in CLP.
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.
