As the lowest chronic toxicity result, the 21 d-NOEC (reproduction) of Daphnia magna (0.32 mg/l) was adopted.

On the basis of the results noted in the study, classification under the Dangerous Substance Directive (67/548/EEC) and the CLP Regulation (EC No 1272/2008 stands as per the acute studies as follows:

N; R51/53 Dangerous for the environment; Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment.
