Conclusion on classification

According to Regulation (EU) No 286/2011, the test substance was classified as "Very toxic to aquatic life" (Acute 1; H400) with an M-factor of 10 and "Toxic to aquatic life with long lasting effects" (Chronic 1; H410) based on the lowest effect concentrations available (EC50= 0.0139 mg/L and EC10= 0.0062 mg/L for algae) and the test substance having a log Kow > 4.
