- Details on test solutions:
- Standard Solutions used for Sample Quantification
The test item (44.5 mg) was dissolved in purified water and made up to the mark in a 100 mL volumetric flask to prepare a stock solution of 445 mg/L. Defined volumes of this stock solution were diluted with purified water to obtain standard solutions of the test item in the range of 3.34 to 111 mg/L. These solutions were used to calibrate the HPLC-system. - Test organisms (species):

- Dose descriptor:
- LC50
- Effect conc.:

- Nominal / measured:
- nominal
- Conc. based on:

- Basis for effect:
- mobility
- Duration:
- 96 h
- Dose descriptor:
- LC100
- Effect conc.:
- > 100 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mortality (fish)
- Details on results:
- The LOEC, the LC100 and the LC50 at the observation times could not be quantified due to the absence of a toxic effect of the test item at the tested concentration.
- Validity criteria fulfilled:
- yes
- Conclusions:
- The test substance did not show any mortality towards zebra fish up to 100 mg/l. Thus, the substance is considered to be of low toxicity to fish.
- Executive summary:
A GLP-compliant study was performed to determine the toxic effects of test substance to zebra fish during 96 hours according to OECD TG 203. For this purpose, zebra fish (Brachydanio rerio) were exposed in a static non-renewal test to an aqueous test medium at the nominal concentration of 100 mg/L under defined conditions. The decision to perform a limit test was based on the results of a range-finding test. 100 mg/L of test substance and a control were applied in the limit test. The LC50, LOEC and LC100 could not be quantified due to the absence of a toxic effect of the test item at the tested concentration. But it indicated LC50, LC100 and NOEC of the test substance were all above 100mg/L. Thus, it can beconsidered the test substance is low toxicity to zebra fish and is not classified according to EU CLP (Regulation (EC) No 1272/2008).
