Conclusion on classification

With a lowest NOEC (Chronic Value) of 0.019 mg/l (fish) for three trophic levels, while being readily biodegradable (meeting the 10d-window), this substance must be classified as category chronic 2 (the ChV being between 0.1 and 0.01 mg/l) with M=1

With a short term EC50 (algae, 96h) of 0.192 mg/l (thus being below 1 mg/l) the substance must be classified as category acute 1 with M=1
