Conclusion on classification
Daphnia
48 -h EC50 (mobility) > 97 mg/L (geom. mean measured)
Algae
72 -h EC50 (growth rate) = 68 mg/L (geom. mean measured)
72 -h EC10 (growth rate) = 18 mg/L (geom. mean measured)
The test item is not readily biodegradable.
Algae was chosen as most sensitive species. Since the EC50 value is greater than 1 mg/L, the test item is not classified for acute aquatic toxicity. However, the test item is classified for chronic aquatic category 3 and labelled with H412 based on the 72 -h EC50 value of 68 mg/L (growth rate).
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.
