CAS number: -
The acute toxicity of the test substance to Daphnia magna was determined in a 48-hour static test according to the OECD Guideline for Testing of Chemicals, Section 2, No. 202, adopted 4 April 1984 ( issued 1993 ) and EU-Guideline 92/69, EEC Nr. L 383 A, C. 2, (29th Dec. 1992 ). The study was performed under Good Laboratory Practice (GLP) conditions in Switzerland.
The nominal concentrations tested were 45, 100 and 220 mg test article/l, a vehicle and a blank control without any addtions. The test concentrations were prepared from a 1 g/l stock solution. In all test concentrations non alteration of the test substance was observed after 48 hours. During the test the test article concentrations in the analysed test media were in the range of 87 - 95 % of the nominal values. Therefore, the reported results are related to the actual mean values of the analysed concentrations of the test article in the test medium, measured at the beginning and at the end of the test.
No immobilization and abnormal behaviour of the Daphnia was observed in the controls.
EC0 = 39 mg/L
EC50 = 146 mg/L
EC100 > 203 mg/L
