Conclusion on classification

Classification and labelling according to acute aquatic toxicity data

Justification for classification or non classification

Three acute tests have been performed with fish, daphnia and algae. The effect with the lowest concentration has been observed in a fish study (LC50 (96 h): 1.1 mg/L). Therefore, classification for acute effects is not required.

Classification and labelling according to chronic toxicity data

Justification for classification or non classification

The lowest effect values in chronic value is a NOEC of 0.6 mg/L (daphnia).

The substance is readily biodegradable and has a log Pow<3. Therefore, the hazard category Aquatic Chronic 3 toxicity applies.
