Additional information

Conclusion on classification

Based on the available data (L(E)C 50 values between 1.8 and 11 mg/L), the substance is not classified for acute aquatic toxicty. Since the substance is not readily biodegradable and the lowest chronic toxicity value was 0.3 mg/L, classification as Aquatic Chronic 2 is required in accordance with Regulation EC No 1272/2008.
