Conclusion on classification

Fish acute data: 96-hour LC50 >100 mg/L.


Daphnia acute data: 48h-EC50 >100 mg/L.


Algae growth inhibition data: 72h-ErC50 value (growth rate): 350.32 mg/L; 72h-EyC50 value (yield): 197.37 mg/L; 72h No-Observed Effect Concentration (NOEC): 80 mg/L (growth rate and yield).


Also considering the substance is not readily biodegradable (persistent), therefore according to Regulation (EC) 1272/2008, amendment 286/2011, table 4.1.0, this substance shall not be classified for hazardous to the aquatic environment.
