Additional information

Key study: The acute toxicity of the test substance on Daphnia magna was assessed in an Acute immobilisation test, over an exposure period of 48 hours in a static system, in accordance with OECD Guideline 202 (GLP study). Because no toxic response was observed during the preliminary range-finding test, a limit test was carried out using only one test concentration (100 mg/L) and one control group in the definitive study under static conditions. Twenty animals, divided into four groups (glass beaker) of five animals each were used at the test concentration and for the control. The EC50 (48 h) value was determined to be > 100 mg/L based on immobilization. The LOEC (48 h) was > 100 mg/L and the NOEC (48 h) was 100 mg/L.
