- TOC analysis
- Details on sampling:
- Samples for possible analysis were taken from all test concentrations and the control according to the schedule below.
Frequency at t=0 h and t=48 h
Volume 50 mL
Storage Samples were stored in a refrigerator (2 - 8°C) until analysis.
At the end of the exposure period, the replicates were not pooled at each concentration before sampling. Instead samples were taken from one vessel of each group.
Additionally, reserve samples of 50 mL were taken for possible analysis. If not used, these samples were stored in a refrigerator (2 - 8°C) for a maximum of three months after delivery of the draft report, pending on the decision of the sponsor for additional analysis.
No. of repeats: at least 3
Test solutions
- Vehicle:
- no
- Remarks:
- Water Accomodated Fractions (WAFs) were used
- Details on test solutions:
- The batch of GURJUN BALSAM OIL tested was a clear colourless to pale yellow liquid. The item was a UVCB substance poorly soluble in test medium at the loading rates initially prepared. No correction was made for the purity/composition of the test item.
Preparation of test solutions started with loading rates individually prepared ranging between 1.0 and 100 mg/L in the combined limit/range-finding test and between 0.10 and 2.2 mg/L in the final test. A 2-day period of magnetic stirring in closed vessels with minimal headspace and in the dark was applied to ensure maximum dissolution of the test item in medium. The obtained mixtures were allowed to settle overnight. Thereafter, the aqueous Water Accommodated Fractions (WAFs) were collected by means of siphoning and used as test concentrations. As the two highest concentrations in the combined limit/range-finding test contained undissolved test material when observed under microscope and the highest concentration was hazy, it was decided to use glass wool to siphon test solutions in the final test. All test solutions prepared for the final test were clear and colorless at the end of the preparation procedure. In addition, microscopic observation of WAFs showed that they did not contain undissolved test material.
Any residual volumes were discarded.
Test organisms
- Test organisms (species):
- Daphnia magna
- Details on test organisms:
- Species: Daphnia magna (Crustacea, Cladocera) (Straus, 1820), at least third generation, obtained by a cyclical parthenogenesis under specified breeding conditions.
Source: In-house laboratory culture with a known history.
Reason for selection: This system has been selected as an internationally accepted invertebrate species.
Validity of batch: Daphnids originated from a healthy stock, 2nd to 5th brood, showing no signs of stress such as mortality >20%, presence of males, ephippia or discoloured animals and there was no delay in the production of the first brood.
Characteristics: For the test, young daphnids were selected with an age of < 24 hours from parental daphnids older than two weeks.
Start of each batch: With newborn daphnids, i.e. less than 3 days old, by placing about 250 of them into 5 litres of medium in an all-glass culture vessel.
Maximum age of the cultures: 4 weeks
Renewal of the cultures: After 7 days of cultivation half of the medium twice a week.
Temperature of medium: 18-22°C
Feeding: Daily, a suspension of fresh water algae.
Medium: M7, as prescribed by Dr. Elendt-Schneider (Elendt, B.-P., 1990: Selenium deficiency in Crustacea. An ultrastructural approach to antennal damage in Daphnia magna Straus. Protoplasma 154, 25-33).

- Details on results:
- The measured TOC concentrations were below 1.0 mg/L at the start of the test. This value is considered a sensitivity limit of the method, and therefore, obtained values should be considered indicative. The values measured at the start of the test showed slight increase with the applied dose. A concentration of approximately 0.40 mg/L was measured at the two highest concentrations tested indicating a possible solubility limit in test medium.
At the end of the test a significant decrease of the measured TOC concentrations was observed at the two highest loading rates.
No immobility was observed in the control and at the two lowest test concentrations during the entire exposure period. At 24 hour of exposure 11 and 15% of daphnids were immobilized in WAFs of 1.0 and 2.2 mg/L, respectively.
At the end of the test, the observed effects were not increasing with the applied dose; in contrary, immobilization decreased with applied dose after reaching 100% at WAF of 0.46 mg/L. One possible explanation for the observed effects can be the decrease of the concentration in the two highest groups at the end of the test. Nevertheless, the immobilization observed at WAF of 1.0 mg/L was above 50% in both, the combined limit/range-finding test and the final test. Therefore, for the worst-case-scenario the effects parameters were calculated after exclusion of the highest WAF. - Results with reference substance (positive control):
- In conclusion, the actual responses in this reference test with K2Cr2O7 are within the ranges of the expected responses at the different concentrations, i.e. the 48h-EC50 was between 0.3 and 1.0 mg/L. Hence, the sensitivity of this batch of D. magna was in agreement with the historical data collected at Charles River Den Bosch.
The 24h-EC50 was 0.95 mg/L with a 95% confidence interval between 0.85 and 1.1 mg/L.
The 48h-EC50 was 0.59 mg/L with a 95% confidence interval between 0.52 and 0.66 mg/L. - Reported statistics and error estimates:
- Calculation of EL50:
The 24- EL50-value could not be calculated as the effects observed at 24 hour of exposure were below 50%. The 48h-EL50-value was calculated with the Spearman-Karber procedure. The highest WAF was not included in the analysis .
ToxRat Professional v 3.2.1 (ToxRat Solutions® GmbH, Germany) was used to perform the analyses.

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Remarks:
- In the control, no daphnids became immobilised or showed other signs of disease or stress. The oxygen concentration at the end of the test was ≥3 mg/L in control and test vessels.
- Conclusions:
- The 48h-EL50 for Daphnia magna exposed to GURJUN BALSAM OIL was 0.40 mg/L (95% confidence interval between 0.34 and 0.48 mg/L).
- Executive summary:
A full OECDTG 202 GLP test was performed with daphnia magna, based on the results of a preceding limit/range-finding test. Water Accommodated Fractions (WAFs) of GURJUN BALSAM OIL oil were prepared and used as test concentrations.Twenty daphnids per group (5 per replicate, Quadruplicate) were exposed to an untreated control and to Water Accommodated Fractions (WAFs) individually prepared at loading rates of 0.22, 0.46, 1.0, 2.2 and 4.6 mg/Lunder static conditions. The total exposure period was 48 hours and samples for Total Organic Carbon (TOC) analyses were taken at the start and at the end of the test. The exposure was performed in airtight closed vessels with headspace reduced to minimum. The measured TOC concentrations were below 1.0 mg/L at the start of the test. This value is considered a sensitivity limit of the method, and therefore, obtained values should be considered indicative. The values measured at the start of the test showed a slight increase with the applied dose. A concentration of approximately 0.40 mg/L was measured at the two highest concentrations tested indicating a possible solubility limit in test medium. Since TOC-analysis is a non-specific method, the effect parameters were reported in terms of loading rates initially prepared. In conclusion, the 48h-EL50 for Daphnia magna exposed to GURJUN BALSAM OIL was 0.40 mg/L (95% confidence interval between 0.34 and 0.48 mg/L).
