Additional information
Conclusion on classification
Classification related key information
Biodegradation in water: under test conditions no biodegradation observed
Bioaccumulation: Bioaccumulation in organisms is negligible, based on the calculated log Pow of -2.90 to -2.08
Acute toxicity:
- to fish: LC50 (96h) = 330 mg/L (nominal)
- to aquatic invertebrates: EC50 (48h) = 31.1 mg/L (nominal)
- to algae: ErC50 (72h) = 20 mg/L (nominal)
Chronic toxicity:
- to fish: no data available
- to aquatic invertebrates: EC10 (21d) = 1.9 mg/L (nominal)
- to algae: ECr10 (72 h): 1.34 mg/L (nominal)
Classification justification according to CLP
According to the data listed above the substance is not rapidly biodegradable. The acute aquatic toxicity L(E)C50 is >1 mg/L. The chronic NOEC is > 1 mg/L. Based on the available data the self-classification for the substance is Aquatic Chronic 3 according to the consolidated version of Regulation (EC) No 1272/2008 (date: 01.03.2018) and further amendments (ATPs).
