Additional information

To determine the toxicity of 1-Ethyl-3-methylimidazolium acetate to aquatic invertebrates, a GLP study following the method laid down in OECD guideline 202 using Daphnia magna was performed. The calculated EC50 (48h) value in this study was 190 mg/L, related to the analytically verified nominal concentrations (BASF SE 2011).
