- Duplicate samples from the freshly prepared test media of all test concentrations and the control were taken at the start of the test
- For the determination of the stability of the test item under the test conditions and of the maintenance of the test item concentrations during the test period, duplicate samples from the test media of all test concentrations and the control were collected at the end of the test (after 48 hours) by pouring together the contents of the test beakers of each treatment
- All samples were diluted by a factor of 2 with acetonitrile
- Additional samples of the control and the dilution solvent were taken at each sampling test start and test end without any sample treatment
- One sample from the freshly prepared stock solution and duplicate samples from the freshly prepared test media of all test concentrations and the controls were taken at the start of the test - Vehicle:
- no
- Details on test solutions:
- - supersaturated stock suspensions of the test item was prepared separately by suspending test item in test water at concentrations of 10, 4.5, 2.1 and 0.9 mg test item/L
- suspensions were stirred separately for approximately 24 hours to dissolve as much test item as possible
- test solutions were extracted from below the water surface. An adequate volume of the water accommodated fraction of 0.9 mg test item/L was mixed into test water to obtain the desired dilution of nominal 0.4 mg test item/L.

- Age at study initiation (mean and range, SD): From 0 to 0 hours old
- Source: taken from ibacon's in house laboratory culture.
- Feeding during test : no
ACCLIMATION
- Acclimation period: Was not necessary, since the test was performed in the same medium as the culturing
- Acclimation conditions (same as test or not): The daphnids were bred in the laboratories of ibacon under similar temperature and light conditions as used in the test. The cultivation of the parental daphnids was performed in Elendt M4 medium (see 6.5). The test organisms were not first brood progeny.

8.6 to 9.0 mg/L in the aged test media - Nominal and measured concentrations:

- Details on test conditions:
- TEST SYSTEM
- Test vessel: Glass beakers of 100 mL volume containing approximately 60 mL of test medium
- Type: closed (test vessels were covered with a lid to reduce the loss of water due to evaporation and to avoid the entry of dust into the solutions)
- Aeration: no
- No. of organisms per vessel: 5
- No. of vessels per concentration (replicates): 4
- No. of vessels per control (replicates): 5
- No. of vessels per vehicle control (replicates): 4

- Conclusions:
- For the conducted semi-static acute immobilization test with Daphnia magna, applying nominal concentrations of 0.4 to 10 mg/L jasmine absolute, effect concentrations were determined on basis of measured concentrations:
- 48 h EC50: 0.705 mg/L
- 48h LOEC: 0.9 mg/L
- 48h NOEC: 0.4 mg/L - Executive summary:
The 48-hr-acute toxicity of jasmine absolute to Daphnia magna (Straus) was studied under semi-static conditions. Daphnids were exposed to control and test chemical at nominal concentrations of 10, 4.5, 2.1, 0.9 and 0.4 mg test item/L for 48 hr. Immobilisation and sublethal effects were observed daily. The 48-hour EC50 was 0.705 mg/L. The 48-hr NOEC based on immobilization was 0.4 mg/L
Based on the results of this study, jasmine absolute would be classified as toxic to D. magna in accordance with the EU CLP Regulation.
This study is classified as acceptable and satisfies the guideline requirements for an acute toxicity study with freshwater invertebrates.
Reference
After 48 hours of exposure no immobilisation of the test animals was observed in the control and the lowest test item concentration of 0.4 mg test item/L. At the concentration of 0.9 mg test item/L, 18 animals were immobile and 20 animals were immobile at the concentrations of 4.5 and 10 mg test item/L.
