Conclusion on classification

Based on both the fish and daphnia acute toxicity values being less than 1 mg/L, the substance warrants a classification as Category Acute 1 (H400: Very toxic to aquatic life).

 

Based on the lowest of the two long term toxicity study values (i.e. EC10 from short term toxicity to aquatic algae study = 139.8 µg/L), the substance warrants a classification as Category Chronic 2 (H411: Toxic to aquatic life with long lasting effects).
