- Details on test solutions:
- PREPARATION AND APPLICATION OF TEST SOLUTION (especially for difficult test substances)
- Method: Preparation of test solutions started with an aqueous mixture prepared at 100 mg/L. The mixture was magnetically stirred for 3 days to ensure maximum dissolution in test medium. The resulting dispersion was filtered through a 0.45 µm membrane filter (Whatman; RC55) to remove the undissolved test item. The lower test concentrations were prepared by subsequent dilutions of the filtered Saturated Solution (SS) in test medium. Note that weighing and formulation were performed under dimmed light conditions.

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Remarks:
- 1) No mortality was observed in the control. 2) Test conditions were maintained constant 3) Dissolved oxygen concentration has been at least 60% of the air saturation (> 5mg/L at 22°C). 4) Results were based on the average concentrations
- Conclusions:
- No effects were observed in any of the concentrations tested up to and including the limit of solubility. The 96h-LC50 exceeded 0.011 mg/L, being the average measured concentration in a filtered saturated solution initially prepared at a loading rate of 100 mg/L. This concentration was considered the limit of solubility in test medium. Due to the low solubility of the test item in test medium, concentrations toxic for carp could not be reached.
- Executive summary:
This study was performed to assess the effect of the test substance on the mortality of carp (Cyprinus carpio) after 96 hours of exposure. The study was conducted in accordance with OECD Guideline for Testing of Chemicals No. 203 and GLP, under semi-static conditions.
A static range-finding test was performed to determine nominal concentrations for the final test. Three fish per concentration were exposed to 1.0, 10 and 100% of a SS prepared at a loading rate of 100 mg/L. Based on the results of the range-finding test, the following nominal concentrations were tested in the definitive test: 10, 18, 32, 56 and 100% of a SS prepared at a loading rate of 100 mg/L.
For each concentration and control group, 7 carps were exposed to the test substance and an untreated control for 96 hours in all-glass, open vessels. Test solutions were renewed every 24 hours. Mortality was recorded for each test and control group at 3¼ h, 24 h, 48 h, 72 h and 96 h. Samples taken from fresh and 24h spent solutions, for the 0% and 100% SS concentrations, were analysed to determine the test concentrations. Measured concentrations of the freshly prepared 100% SS solutions were 0.013 mg/L for both the first and last renewal interval. Measured concentrations of the 24 -hour spent 100% SS solutions were 0.0074 and 0.010 mg/L for the first and last renewal period respectively. The average exposure concentration was calculated to correspond with 0.011 mg/L.
The 96h-LC50 exceeded 0.011 mg/L, being the average measured concentration in a filtered saturated solution initially prepared at a loading rate of 100 mg/L. This concentration was considered the limit of solubility in test medium. Due to the low solubility of the test item in test medium, concentrations toxic for carp could not be reached.
