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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
