- Details on sampling:
- Chemical analysis of the test item to determine exposure concentration and stability of the test item during test duration was performed at the test site biochemA, Im Oberwald 19b, D-79359, Riegel a.K., Germany. Samples were taken in 2 replicates from the test concentrations (A, B, C, D and E) and the control (NC) at 0 h, 24 h (before/after renewal) and 48 h from the separate test vessels without daphnids. For stabilisation 4 ml acetonitril was submitted in 8 mL glass vials. With every sampling 1 mL of the test solution was taken and filled into the glass vials. This resulted in a dilution of test solution by factor 5. The samples were kept in the freezer at < -18°C. After the experimental phase one replicate of every sampling was sent to the analytical laboratory. The second replicate was kept in the freezer as retain sample until finalization of the study. Proper departure and arrival of the samples was documented.
The sampling and documentation was conducted according to the following specification:
- After 0 h exposure, two replicates per treatment group of NC, A (6.25 mg/l), B (12.5 mg/l), C 25 mg/l, D (50 mg/l) and E (100 mg/l) are sampled;
- After 24 h exposure:
Before renewal of the test solutions, two replicates per treatment group of NC, A, B, C, D and E are sampled. After renewal of the test solutions, two replicates per treatment group of NC, A, B, C, D and E are sampled.
- After 48 h exposure, two replicates per treatment group of NC, A, B, C, D and E are sampled - Vehicle:
- no
- Test organisms (species):
- Daphnia magna
- Details on test organisms:
- The test organism Daphnia magna Straus originates from the clone breeding of the Federal Environment Agency, department IV 2.4, Berlin, and was cultivated at Hydrotox GmbH since October 2012. The daphnids are cultured at 20 2 °C with 16 h light : 8 h dark and placed into fresh M4 medium twice a week. They are kept at approx. 10 animals / 200 mL and fed on workdays with Desmodesmus subspicatus algae corresponding to 0.1 mg C × daphnid-1 × day-1. The test organisms used were 3.25 – 22.5 h old at the start of the test.

- Results with reference substance (positive control):
- Quality assurance takes place at regular intervals by testing the sensitivity of the test organisms to the reference item potassium dichromate (Sigma, Steinheim, Germany; Lot no.: MKBF2111V, expiration date: January 2019). The recent quality testing was performed in October 2017 with EC50 = 1.77 mg/l (1.63 – 2.05 mg/L Cl-95%) (24 h) which is in the declared range of 0.6 - 2.1 mg/L (24 h) according to OECD 202.
- Reported statistics and error estimates:
- The effect occurrence after 24 h and 48 h exposure was calculated. With the statistical software ToxRat Professional 2.10.05 (ToxRat Solutions GmbH, Alsdorf, Germany), EC and LOEC/NOEC were determined as far as mathematically possible.
- Validity criteria fulfilled:
- yes
- Conclusions:
- The Daphnia magna acute immobilisation test was performed with five loading rates between 6.25 mg/L and 100 mg/L of the test item. The following results were obtained: ELR50 (48 h) > 100 mg/L and NOELR (48 h) >= 100 mg/L.
- Executive summary:
The Daphnia magna acute immobilisation test was performed with five loading rates between 6.25 mg/L and 100 mg/L of the test item. The insolubility of the test item, resulting in no detection of the test item. Therefore all results are given in relation to the nominal test item concentrations. The test is valid according to OECD Test Guideline 202 (13 April 2004). The following results were obtained: ELR50 (48 h) > 100 mg/L and NOELR (48 h) >= 100 mg/L.

Results
The Daphnia magna acute immobilisation test was performed with five loading rates between 6.25 mg/L and 100 mg/L. The insolubility of the test item, resulting in no detection of the test item. Therefore all results are given in relation to the nominal test item concentrations. The test is valid according to OECD Test Guideline 202 (13 April 2004). Substance-specific chemical analysis was based on the detection of the test item, which has a purity of 100%. In the control, the test item was not detected. In all test item treatments the test item was below the Limit of Detection (LOD = 0.0310 mg/L).
Effect concentrations
The effect concentrations after 24 h and 48 h exposure were calculated with the statistical software ToxRat Professional 3.2.1 (Table 3; Appendix II). Because the measurements of the chemical analysis were below the limit of detection, it is not feasible to conduct the data evaluation based on the measured test item concentrations. Therefore all results are given in relation to the nominal test item concentrations.
Test parameters
- The pH was 7.3 – 8.2 in the control and 7.5 – 8.3 in the test item treatments.
- The dissolved oxygen concentration was 7.2 – 8.5 mg/L in the control and 7.7 – 8.5 mg/L in the test item treatments.
- The temperature during the exposure was 19.9 – 21.0 °C (required 18 - 22 °C, constant within +- 1 °C).
Criteria of validity
- Immobilisation of the test organisms in the control at the end of the test was 0 % and therefore ≤ 10 %.
- Dissolved oxygen concentrations at the end of the test in the control and the test item treatment were ≥ 7.2 mg/L and therefore ≥ 3 mg/L.
