Additional information

Conclusion on classification

The following data are available for the evaluation of the aquatic toxicity


Short-term toxicity


Fish: LC50 >1000 mg/l


Aquatic invertebrates: EC50 - Daphnia magna > 1000 mg/l.


Algae: ErC50 (72h) > 126 mg/l (nominal); NOEC (72h, growth rate) = 126 mg/l (nominal)


Long-term toxicity


Fish: NOEC (fry length, fry weight) = 4.41 mg/l (TWA, mean measured)


Aquatic invertebrates: NOEC (21d, overall threshold effects) = 1.10 mg/l (nominal)


The substance is not rapidly biodegradable and it not bioaccumulative considering its LogPow. No acute aquatic toxicity was observed. Valid chronic toxicity data are available for daphnids and fish where the NOEC determined is >1 mg/l. Therefore, the substance is not classified for the aquatic toxicity according to the criteria of Regulation (EC) No.1272/2008 (CLP).
