Test organisms
- Test organisms (species):
- Daphnia magna
- Details on test organisms:
- During breeding, daphnids were generally fed three times a week with an algal suspension of the green algae Desmodesmus subspicatus supplied by the Collection of Algal Cultures (SAG, Institute for Plant Physiology, University of Göttingen, 37073 Göttingen / Germany) and cultivated at IES Ltd Laboratories under standardized conditions or a mixture of this algal suspension and a commercial fish diet (Tetra Min® Hauptfutter, supplied by TETRA-GmbH, 49324 Melle / Germany).
At the start of the test, the organisms used in the test were 6 24 hours old and were not first brood progeny.
For evaluation of the quality of the daphnia clone and the experimental conditions, potassium dichromate is tested as a positive control twice a year. The result of the latest positive control test in October 2017 (24-hour EC50: 1.3 mg/L, IES Laboratories Study 20170366) showed that the sensitivity of the test organisms was within the range given by the guideline (24-hour EC50: 0.60 2.1 mg/L).
The test method and the test species are recommended by the international test guidelines.
Study design
- Test type:
- static
- Water media type:
- freshwater
- Limit test:
- yes
- Total exposure duration:
- 48 h
- Post exposure observation period:
- The immobility of the daphnids was determined by visual inspection after 24 and 48 hours of exposure. Those daphnids not able to swim within 15 seconds after gentle agitation of the test vessel were considered to be immobilized.
Observations were also performed for other non-lethal effects (e.g. abnormal behavior or appearance).
Test conditions
- Hardness:
- 250 mg/L as CaCO3
- Test temperature:
- The test was performed in a temperature controlled room with continuous monitoring of the room temperature. The test water temperature was maintained between 20 and 21 °C.
- pH:
- 7.8-7.9
- Dissolved oxygen:
- 8.6-8.7 mg/L
- Salinity:
- 0.8
- Nominal and measured concentrations:
- Nominal Test Item Concentration 1, 10, 100 mg/L
- Reference substance (positive control):
- yes
- Remarks:
- potassium dichromate is tested as a positive control twice a year

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Remarks:
- In the control no daphnids showed immobilization or other signs of disease or stress (e.g., discoloration or unusual behavior such as trapping at the surface water).
- Conclusions:
- The test item Sodium Tetrafluoroborate had no acute toxic effects on Daphnia magna in a static 48-hour test up to the nominal concentration of 100 mg/L under the conditions of the test.
