Additional information
Conclusion on classification
Classification related key information
Biodegradation in water: under test conditions no biodegradation observed
Bioaccumulation: Bioaccumulation in organisms can be expected to be low, based on the experimental log Pow of 3.6
Acute toxicity:
- to fish: LC50 (96h) = 0.067 mg/L (nominal)
- to aquatic invertebrates: EC50 (48h) = 0.15 mg/L (nominal)
- to algae: ErC50 (72h) = > 1.68 mg/L (measured)
Chronic toxicity:
- to fish: no data available
- to aquatic invertebrates: EC10 (21d) = 0.00264 mg/L (measured)
- to algae: ECr10 (72 h): 1.05 mg/L (measured)
Classification justification according to CLP
In accordance to the classification criteria stated in Regulation (EC) No 1272/2008 (CLP), this substance is classified in the Acute hazard category, H400 Very toxic to aquatic life and Aquatic Chronic 1 Category, H410 Very toxic to aquatic life with long lasting effects. M-factors of 10 were derived for acute and chronic classifications.
