- Test item treatment: For weighing out the test item was gently heated up to 40 °C to get it homogeneous liquid.
Stock solution: The stock solution (100 mg/L were weighed out) was freshly prepared with dilution water.
Dispersion treatment: Agitation
Limit concentration: 100 mg/L
Test duration 48 h, static
Test vessels Glass beakers (4 cm ID x 7 cm H), 50 ml capacity
Test volume 20 ml
Dilution water ISO Test water, according to OECD 202, Annex 3
Test organisms
- Test organisms (species):
- Daphnia magna
- Details on test organisms:
- Test organism: Daphnia magna STRAUS (Clone 5)
Reason for the selection of the test organism: Daphnia magna belongs, in accordance with the study guideline, to the suitable Daphnia types and is bred at the test facility.
Origin: lnstitut für Wasser-, Boden- und Lufthygiene (WaBolu)
Breeder: DR. U. NOACK-LABORATORIEN
Culture: In glass vessels (2- 3 L capacity) with approximately 1.8 L culture medium, at 20 ± 2 °C, in an incubator, 16 h illumination, illumination strength max. 20 µE.m-2.s-1.
Culture medium: Elendt M4, according to ELENDT (1990), modified to a total hardness of 160 to 180 mg CaCO3/L.
Feeding: At least 5 times per week ad libitum with a mix of unicellular green algae, e.g. Pseudokirchneriella subcapitata, Desmodesmus subspicatus and Chlorela vulgaris, with an alga cell density of> 10^6 cells/ml. The daphnids were not fed during the study.
Number of study organisms: 20 animals, divided into 4 parallel samples, each with 5 animals per limit concentration and control
Age of test organisms: 2 to 24 h old daphnids were used for the definitive study. They were obtained by removing the mother animals twice within 22 h.
Acclimatization: At least 2 h in dilution water

Applicant's summary and conclusion

- yes
- Conclusions:
- At the limit concentration of nominal 100 mg/L of the test item no effect to Daphnia magna was observed.
- Executive summary:
In the acute immobilization test with Daphnia magna (STRAUS) the effects of the limit concentration 100 mg/L of the test item were determined according to OECD 202 (2004) at DR.U. NOACK-LABORATORIEN, Kathe-Paulus-Str. 1, D-31157 Sarstedt. The limit test was conducted under static conditions over a period of 48 h from 2009-04-21 to 2009-04-23. 20 test organisms were exposed to the limit concentration and the control. The limit concentration 100 mg/L and the control were analysed via DOC analysis in the fresh media (0 hours) and in the old media (after 48 hours). All effect values are given based on the nominal concentrations of the test item Hostacerin SFO. Water quality parameters of pH-value and dissolved oxygen concentration, measured at 0 and 48 h, were determined to be within acceptable limits. The validity criteria of the test guideline were fulfilled.
At the limit concentration of nominal 100 mg/L of the test item no effect to Daphnia magna was observed.
