- Results with reference substance (positive control):
- The percentage immobility for the reference item was determined after 24 h. The EC50-value with 95 % confidence interval (CI) was calculated by sigmoidal dose-response regression. The EC50-value for the most recent of the monthly performed reference tests was:
EC50: 2.1 mg/L (CI 1.8 - 2.4 mg/L)
The EC50-value of the reference item potassium dichromate after 24 h is within the prescribed concentration range of 0.6 - 2.4 mg/L of quality criteria according to AQS P 9/2 (02/2000) for daphnids clone 5 cultured in Elendt M4 medium. The EC50-value of the reference item is also within the recommended range of 0.6 - 2.1 mg/L according to OECD-Guideline 202.
Any other information on results incl. tables
During the test, the incubator temperature was 19°C.
The water quality parameterswere within the acceptable limits.

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- At the saturated solution with a geometric mean measured concentration of 1.17 mg/L of the test item , no effects were observed on Daphnia magna.
- Executive summary:
In the acute immobilisation test with Daphnia magna (STRAUS), the effects of the saturated solution* with 5 mg/L of the test item was determined according to OECD 202 (2004). The limit test was conducted under static conditions over a period of 48 h .
A saturated solution was prepared by stirring with approximately 1100 rpm for 48 h at room temperature. After completion of stirring, undissolved test item was removed by centrifugation for 10 minutes at 18533 g. Twenty daphnids were exposed to the saturated solution concentration and the control.
The saturated solution of the test item and the control were analytically verified by HPLC-DAD at the start of the exposure (0 h) and at the end of the exposure (48 h).
The measured concentration of the test item was 1.16 mg/L at the start of the exposure (0 h) and 1.18 mg/L at the end of the exposure (48 h). The geometric mean measured test item concentration was calculated to be 1.17 mg/L.The effect values given are based on the geometric mean measured concentrations of the test item .
The water quality parameters (i.e. pH-value and dissolved oxygen concentration), measured at the start (0 h) and at the end of the exposure (48 h), were within the acceptable limits. The validity criteria of the test guideline were fulfilled.
At the saturated solution* with a geometric mean measured concentration of
1.17 mg/L of the test item ,
no effects were observed on Daphnia magna.
