Additional information

Conclusion on classification

Aquatic acute toxicity

96 h, LC50 (Danio rerio): ≥ 3mg/L (nominal concentration)

48 h, EC50 (Daphnia magna): 44.3 mg/L (nominal concentration)

72 h, ErC50 (Pseudokirchneriella subcapitata): 2.71 mg/L (nominal concentration)

 

Aquatic chronic toxicity

72 h, ErC10 (Pseudokirchneriella subcapitata): 0.96 mg/L (geometric mean measured concentration)

 

Biodegradation: not readily biodegradable

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The ErC50 was smaller than 10 mg/L and the substance is not readily biodegradable. As a result the substance has to be classified as hazardous to the aquatic environment: Aquatic Chronic 2 with H411: "Toxic to aquatic life with long lasting effects" under Regulation (EC) No 1272/2008, as amended for the ninth time in Regulation (EU) No 2016/1179.
