Volume: 1.5 mL from the approximate centre of the test vessels
Storage: Samples were stored in a freezer (≤-15°C) until analysis at the analytical laboratory of the Test Facility.
Additionally, reserve samples of 1.5 mL were taken from all test solutions for possible analysis. If not already used, these samples were stored in a freezer (≤-15°C) for a maximum of three months after delivery of the draft report, pending on the decision of the sponsor for additional analysis. - Vehicle:
- no
- Details on test solutions:
- The batch of Octopamine hydrochloride tested was a white to off-white powder with a purity of 99.8% and completely soluble in test medium at the concentrations tested. No correction was made for the purity/composition of the test item. Preparation of test solutions started with the highest concentration of 100 mg/L applying a 15-16 minute period of magnetic stirring to accelerate dissolution of the test item in test medium. Lower test concentrations were prepared by subsequent dilutions of the highest concentration in test medium. All test solutions were clear and colorless at the end of the preparation procedure. Any residual volumes were discarded.

- Range-Finding Test A range-finding test was performed to provide information about the range of concentrations to be used in the final test. Test procedure and conditions were similar to those applied in the final test with the following exceptions:
Three fish per concentration were exposed to a range of nominally 0.10 to 100 mg/L increasing by a factor of 10.
Temperature and pH were only measured in the lowest and the highest test concentration. Dissolved oxygen concentrations were measured in the lowest and the highest test concentration at the start of the test and after 24, 48 and 96 hours of exposure. After 72 hours of exposure, dissolved oxygen concentrations were measured in all test concentrations.
Aeration was introduced after 72 hours of exposure, after dissolved oxygen was observed to be below 5 mg/L in the two highest test concentrations
Test Concentrations: Octopamine hydrochloride 100 mg/L, the regulatory limit concentration. Control Test medium without test item or other additives.

- Dose descriptor:
- LC50
- Effect conc.:
- > 100 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mortality (fish)
- Details on results:
- Range-Finding test
No mortality or clinical effects were observed at any of the test concentrations during the test period. Based on these results, samples taken from nominal 100 mg/L were analysed. The initial concentration was 103 mg/L. This concentration decreased to 73% of the initial concentration at the end of the test (see also Table 2 of the appended Analytical Report). All test conditions were generally maintained within the limits prescribed by the study plan. After 72 hours of exposure, the dissolved oxygen was below 5 mg/L at the two highest test concentrations. It was consequently decided to introduce aeration for the remaining test period.
Final Test
Measured Test Item Concentrations
Samples taken from the control and the limit concentration were analysed. The measured concentrations were at 97-105% of the nominal concentration throughout the test duration. Based on these results, the nominal exposure concentrations were used to express the effect parameters.
Mortality and Other Effects
No mortality or clinical effects were observed at any of the test concentrations during the test period. The responses recorded in this test allowed for reliable determination of an LC50 and were in agreement with the results of the range-finding test.
Experimental Conditions
All test conditions remained within the ranges prescribed by the study plan (pH: 6.0-8.5, constant within 1 unit; temperature 20-24°C, constant within 2°C; oxygen > 60% of air saturation). - Results with reference substance (positive control):
- Incidence of mortality observed in the reference study:
PCP Nominal conc. (mg/L) Initial number Of fish Cumulative number of dead fish recorded at various time points after start of exposure Total Mortality (%)
2½h 24h 48h 72h 96h
0.10 5 0 0 0 0 0 0
0.22 5 0 5 5 5 5 100
0.46 5 0 5 5 5 5 100 - Reported statistics and error estimates:
- No LC50 could be calculated because the test item proved to be non-toxic (LC50 > maximum concentration).
- Validity criteria fulfilled:
- yes
- Conclusions:
- In conclusion, the 96h-LC50 was beyond the range tested, i.e. exceeded an analytically confirmed nominal concentration of 100 mg/L.
- Executive summary:
The objective of the study was to evaluate Octopamine hydrochloride for its ability to generate acute toxic effects in Cyprinus carpio during an exposure period of 96 hours and, if possible, to determine the LC50 at all observation times. The study procedure described in this report was based on the OECD guideline No. 203, 1992. The batch of Octopamine hydrochloride tested was a white to off-white powder with a purity of 99.8% and completely soluble in test medium at the concentrations tested. A final test was performed based on the results of a preceding range-finding test. Seven carps per test group were exposed to an untreated control and to nominally 100 mg/L. The total exposure period was 96 hours, test solutions were renewed after 48 hours of exposure and samples for analytical confirmation of exposure concentrations were taken from fresh and old solutions of both refreshment periods. No mortality or clinical effects were observed at any of the test concentrations during the test period. Samples taken from the control and the limit concentration were analysed. The measured concentrations were at 97-105% of the nominal concentration throughout the test duration. The study met the acceptability criteria prescribed by the study plan and was considered valid. In conclusion, the 96h-LC50 was beyond the range tested, i.e. exceeded an analytically confirmed nominal concentration of 100 mg/L.
