SELECTION OF DAPHNIA
- Experiment 1: 18 hours 40 minutes before the start of the test, the adult animals were separated from the young. 0.75 hours before test start, the adults were caught with the help of a glass tube, and the newborn daphnia, aged between 0 and 17 hours 55 minutes, were sieved from the medium and immediately placed into a beaker containing dilution water. After the settling-in period, animals which showed no apparent damage were used for the test.
- Experiment 2: 18 hours before the start of the test, the adult animals were separated from the young. 1 hour before test start, the adults were caught with the help of a glass tube, and the newborn daphnia, aged between 0 and 17 hours, were sieved from the medium and immediately placed into a beaker containing dilution water. After the settling-in period, animals which showed no apparent damage were used for the test.

- IMMOBILITY
- Experiment 1: All concentrations showed toxicity between 95 and 100 % immobilisation. Trapping on the surface or clotting was not observed. None of the animals was immobilised in the blank control.
- Experiment 2: The two highest concentrations showed toxicity between 90 and 100 % immobilisation. None of the animals was immobilised in the lower concentrations and in the blank control.
ANALYTICAL DETERMINATIONS
- Experiment 1: 123 - 135 % of the nominal concentrations at the beginning of the test and 108 - 131 % of the nominal concentration after 48 hours.
- Experiment 2: 79 - 110 % of the nominal concentrations at the beginning of the test and 76 - 115 % of the nominal concentration after 48 hours. - Results with reference substance (positive control):
- - Results with reference substance valid?
yes
- Relevant effect levels: 24h-EC50: 1.6 mg/L - Reported statistics and error estimates:
- Since immobility in experiment 1 was observed from 95 to 100% in all treatments, no statistical evaluation was conducted. However biological results were given in a range of concentrations or determined as lower orlower as or higher than a certain concentration. The estimation of the biological results from experiment 2 was accomplished using the software ToxRat® Professional, version 3.2.1.

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- The EC50 (48 h) for immobilisation was determined to be 0.795 mg/L. The corresponding NOEC (48 h) was 0.5 mg/L.
- Executive summary:
The short term toxicity of test item to Daphnia magna STRAUS was assessed according to OECD 202 resp. EU C.2 over a period of 48 hours.
Two valid experiments were performed. In the first experiment all concentrations showed toxicity between 95 and 100 % immobilisation. In the second experiment the two highest concentrations showed toxicity between 90 and 100 % immobilisation.
The content of the test item in the test solutions was analytically verified using LC-MS-MS-determination. The determination of the biological results was based on the geometric mean of the measured concentrations.
The EC50 (48 h) for immobilisation was determined to be 0.795 mg/L. The corresponding NOEC (48 h) was 0.5 mg/L.
