Sampling and analysis
- Analytical monitoring:
- yes
Test solutions
- Vehicle:
- yes
- Details on test solutions:
- During validation of the analytical method, the maximal solubility in Danio rerio test medium was determined as 1.6 mg/L. Because stability in test medium after 48 hours was only 81.4 % no saturated solution prepared Acetone was used as solvent to prepare the test solutions .at the limit of solubility directly before the start of the test and at medium renewal after 48 hours.
A stock solution containing 1600 ± 8mg/L in acetone was prepared. The concentration of the stock solution was 1000-fold higher than the concentration in the treatment (1.6 mg/L resp. the estimated maximal solubility in Danio test medium). For the solvent control, acetone in a concentration of 1 mL/L was used.
Test organisms
- Test organisms (species):
- Danio rerio (previous name: Brachydanio rerio)
- Details on test organisms:
- Species: Danio rerio
Variety: Hamilton-Buchanan
Age: sexually immature young fish, length 2 ± 1 cm
Origin:
The original animals were obtained from Umweltbundesamt (UBA) and used for breeding and production of eggs. The offspring of the original animals is used in the test.
Husbandry:
Danio rerio is routinely used for toxicity tests.
Before being used for the test, the fish are kept for twelve days under test conditions. During this period, mortality must stay below 5 %.
Food:three times a day; warm-water fish food and daphnids
Medium renewal: twice a week
Photo period: 12/12 hours, using neon tubes
Temperature: 23 ± 2 °C

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- The following results for the test item Ukanol FR 70 could be determined:
96h NOEC ≥ 0.85 mg/L
96h LC50 > 0.85 mg/L - Executive summary:
The acute toxicity of Ukanol FR 70 against Danio rerio Hamilton Buchanan was determined following EU-Method C.1 resp. OECD Guideline 203.
The main study was performed as semi-static limit test using a concentration of 1.6 mg/L, representing the maximal solubility in test medium. The maximal solubility in test medium was determined during validation of the analytical method. Acetone was used as solvent to prepare the test solutions at the limit of solubility. Seven fish were exposed to the test item for 96 hours. After 48 hours the test medium was renewed. In the solvent control and in the treatment no significant mortality was observed. The pH and the oxygen value of the water were normal. During validation of the analytical method, the test item had shown insufficient stability. The recovery after four days had been 68.2 %. Therefore, the study was performed under semi-static conditions. The content of the test item in the test solutions was determined at the beginning and at the end of the test and after 48 h before and after medium renewal using HPLC. The correlation between nominal and measured concentration in the freshly prepared test solution was good (85 % after 0 hours and 99 % after 48 h). The recovery of measured start concentration was 38 % after 48 hours and 29 % after 96 hours. The unexpectedly poor recovery means that the characteristic of the test medium in presence of the animals is not identical with the medium without fish, used during validation of the analytical method. Without much doubt, the loss of test item was caused by ingestion by the fish or adsorption on to the animals or the excrements of the animals. Therefore, the determination of the results was based on the geometric mean of the measured concentrations. The following results for the test item Ukanol FR 70 could be determined:
96h NOEC ≥ 0.85 mg/L
96h LC50 > 0.85 mg/L
