Conclusion on classification
Based on the available data, the substance is classified as acute category 1 according to CLP Regulation (EC) no. 1272/2008 as values LC50-96 h (for fish) and also EC50-48h (for crustacea) are <1mg/L. The substance is also classified as aquatic chronic 1, taken the lowest value of available chronic toxicity NOEC (for algae) and acute aquatic toxicity values according to CLP Regulation (EC) no. 1272/2008.
