- Species, age: Juvenile Daphnia magna, 4 – 24 hours old.
Origin: German Federal Environment Agency, Institut für Wasser-, Boden- und Lufthygiene. Specimens used in the test are bred in the laboratory of the Fraunhofer IME.
Pre-Treatment: Adult Daphnia, at least 3 weeks old, were separated from the stock population by sieving. Batches of 30 to 50 animals were held at room temperature in ca. 1.8 L dilution water for one week. During this week the daphnids were fed daily with an algal suspension (Desmodesmus subspicatus) and ArtemioFluid (JBL). Algae growing in the log-phase were centrifuged and the pellet was re-suspended in a few mL of medium. 5 mL of this suspension was given to 1.8 L Daphnia medium. The water (“ISO water”, pH 6.5, see Table 2) was changed three times per week. Newborn D. magna were separated by sieving, the first generation was discarded. Individuals applied in the test were transferred with a bore Pasteur pipette a few hours after sieving to ensure applying only healthy specimens. - Test type:

During observations of immobility after 24 and 48 hours, all living daphnids were comparable active. No signs of disease or stress were observed in any replicate. - Validity criteria fulfilled:
- yes
- Remarks:
- The test fulfilled all validity criteria. No loading-dependent immobilization effect was observed over the range of the tested nominal loading rates.
- Executive summary:
The 48-hours toxicity of the test item pNCM-111 1100, an UVCB substance, to the daphnid Daphnia magna was determined in a static system (OECD 202) exposed to nominal loading rates of control, 4.27, 9.39, 20.7, 45.5 and 100 mg test item/L.
The test fulfilled all validity criteria. No loading-dependent immobilization effect was observed over the range of the tested nominal loading rates.
Based on the recommendations of the OECD 23 chapter 7.9.2.5 “Water-accommodated fractions reporting of results”, paragraph 153) the evaluation of the biological results was based on nominal loading rates of the test item.
The concentrations of dissolved cobalt, nickel and manganese in the media were measured by ICP-OES (LOQ = 3 µg Co/L, 6 µg Ni/L and 3 µg Mn/L) at test initiation and test termination after 48 hours to improve the interpretation of the observed effects as outlined in the OECD 23.
The 48-hour EL50 and EL10 values for immobilization were determined to be > 100 mg test item /L. The NOELR was ≥ 100 mg test item/L.
