EFFECT PARAMETERS MEASURED (with observation intervals if applicable):
Observations were made after 1 ± 0.5 h, 4 ± 1 h and 24 ± 2 h after the start of the exposure (day 0-1). On days 2-4 of the test, all vessels with living fish were inspected twice per day (morning and afternoon). Test criterion is the death of the fish (=mortality).
TEST CONCENTRATIONS
- Spacing factor for test concentrations: none, only one test concentration
- Range finding study
- Test concentrations: The concentration to be tested was based on the result of a non-GLP pre-test. In the non-GLP pre-test, no toxicity
was observed. Therefore, a limit test was conducted. - Reference substance (positive control):
- no
- Key result
- Duration:
- 96 h
- Dose descriptor:
- LC50
- Effect conc.:
- > 100 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mortality (fish)
- Details on results:
- - No mortality was observed in any treatment at any time during the test.
- Other biological observations: No abnormal behaviour of the surviving fish was observed.
- Mortality of control: no mortality
- Other adverse effects control: none
- At the beginning and at the end of the test, the content of the test item in the test solutions was determined using HPLC-determination. The measured concentration was 105 % of the nominal concentration at the beginning and 109 % at the end of the test.
Therefore, the determination of the biological result was based on the nominal concentration (see Guidance Doc. No.23 (§176)). - Reported statistics and error estimates:
- No statistical analysis was performed, since no effects were observed in the treatment.
- Validity criteria fulfilled:
- yes
- Remarks:
- Did the mortality in the blank control exceed 1 fish at the end of the test? No. Has the dissolved oxygen concentration been at least 60% throughout the test? Yes (93.5% at a minimum).
- Conclusions:
- An acute toxicity study was performed with the zebrafish (Danio rerio) exposed to 5-sulfosalicylic acid for a test duration of 96 hrs using static test conditions. The study was performed in accordance with OECD TG 203, wherefore it is considered to be acceptable for the assessment of the acute toxicity of the test substance to fish.
Under the conditions used for the test no toxicity of 5-sulfosalicylic acid to zebrafish was observed. Thus, the 96h-LC50 for 5-salicylic acid is given as >100 mg/L.
No observations were made which might cause doubts concerning the validity of the study outcome. All validity criteria were met. The result of the test is considered valid. - Executive summary:
The acute toxicity of the test substance to fish was investigated in this study according to OECD TG 203 and GLP. Danio rerio (zebra fish) was used as test organism and exposed to one nominal test concentration (100 mg/L) for 96 hours of test duration under static test conditions. A blank control was running in parallel containing dilution water only. The test was carried out at a temperature between 21.1 and 22.7°C, with a pH range of 7.0-8.3 and an oxygen concentration above the saturation concentration (≥ 90% ASV) throughout the test. In the treatment and in the control, no fish died or showed abnormal behaviour. Based on the obtained results, the 96h-LC50 was determined to be nominal >100 mg/L. At the beginning and at the end of the test, the content of the test item in the test solutions was determined using HPLC-determination. The measured concentration was 105 % of the nominal concentration at the beginning and 109 % at the end of the test. Therefore, the biological result was based on the nominal concentration.
