Conclusion on classification

Considering the 33d-NOEC = 0.20µ/L measured for fish and the results of the ready biodegradability study, the substance should be classified as H400 (Aquatic Chronic 1), with a chronic M-factor = 100. No acute hazard classification is warranted, considering the results of the acute aquatic toxicity studies (no effects up to the water solubility limit).
