Conclusion on classification

According to EC 1272/2008 and related amendment II EC 286/2011, the substance has to be classified for acute aquatic toxicity if 96 hr LC50 (for fish)≤ 1 mg/l and/or 48 hr EC50 (for crustacea)≤ 1 mg/l and/or 72 or 96 hr ErC50 (for algae or other aquatic plants) ≤ 1 mg/l. Since EC50 daphnia = 0.22 mg/l the substance has to be classified for acute aquatic toxicity, H400. Adequate chronic toxicity data are not available, but Category Chronic 1 is not warrated because the substance is rapidly degradable and the log Kow<< 4
