Additional information
The acute immobilisation of the test item to Daphnia magna (STRAUS) was determined according to OECD Guideline 202 / EEC Directive 92/69/EEC Method C.2 .The study was conducted under static conditions over a duration of 48 hours. 20 test organisms were exposed to each test concentration and control. The test item dilutions were clearly dissolved after filtration of the saturated solution in all tested concentration levels throughout exposure. The real test concentrations were calculated based an DOC-analysis: 1.2 - 2.2 - 5.8 - 11.5 - 17.9 mg/L. The EC10 and EC50 values were calculated by probit analysis in the tested concentration range. The EC50 value of the test item was determined to be 9.1 mg/L (nominal value) after 48 h.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
