Additional information

In the Klimisch 1 GLP study the acute toxicity of test item on Daphnia magna was determined in an 48 hour static test according to OECD 202 and EU method C.2. A semi-static range-finding test with concentrations of 0, 0.100, 1.00, 10.0 and 100 mg/L was performed. As no immobilisation was observed in the range-finding test up to 100 mg/L no main test was performed. The measured concentration of the test item in the test item solutions was between 96 – 99 % of nominal concentration. A mean value of 98 % was calculated. Since the mean measured concentration of the test item was between 80 – 120 %, the toxicological endpoints were evaluated using nominal concentrations of the test item. The EC50 is > 100 mg/L.
