Additional information

Short-term toxicity tests are available for all three trophic levels (fish, invertebrates and algae). The 96 -hour LC50 in

zebra fish is 100 mg/L, the 48 -hour EC50 in Daphnia magna is >100 mg/L, and the 72 -hour ErC50 and ErC10 values in algae are >100 mg/L and 100 mg/L, respectively. In an activated sludge respiration inhibition test a 3-hour IC50 value of >1000 mg/L was observed.

Conclusion on classification

Based on all available data for fish, aquatic invertebrates and algae, the test substance needs not to be classified according to Directive 67/548/EEC - Classification, Packaging and Labelling of Dangerous Substances or according to Regulation (EC) No. 1272/2008 on Classification, Labelling and Packaging of Substances and Mixtures (CLP))
