Additional information

In the Klimisch 1 GLP study the acute toxicity of test item on Oncorhynchus mykiss was determined in an 96 hour semi-static test according to OECD 203 and EU method C.1. The test was performed with concentrations of ontrol and 0.512, 1.13, 2.48, 5.45 and 12 mg/L.The mean measured content of the test item in fresh test solutions was 100 % of nominal concentration. The mean measured content of test item in aged test solutions was 99 % of the nominal concentration. Therefore toxicological endpoints were evaluated using nominal concentrations of the test item. The LC50 is 10.1 mg/L.
