Additional information

Conclusion on classification

Three acute aquatic toxicity studies are available. The L(E)C50 for all three trophic levels were between 1 and 10 mg/L and the NOErC algae was 0.39 mg/L. Based on these data, the substance does not have to be classified for acute aquatic hazard. For long-term aquatic hazard, the substance should be classified as Category Chronic 2 (H411), based on both chronic effect data and on acute effect data.
