- Remarks:
- TOC content measurement
- Details on sampling:
- - Preparation of test solutions started with a loading rate of 100 mg/L applying a three-day period of magnetic stirring to reach the maximum dissolution of the test substance in medium. Thereafter, the aqueous Saturated Solution (SS) was collected by means of filtration through a 0.45 μm membrane filter (RC55, Whatman) and used as the highest test concentration. Lower concentrations for the range-finding test were prepared by subsequent dilutions of the SS in test medium. All test solutions were clear and colorless at the end of the preparation procedure.
- Samples for possible analysis were taken from the limit concentration and the control according to the schedule below. In addition, the filter used to prepare the SS was retained in a freezer (≤ -15°C) for possible analysis of the residue.
Frequency: at t=0 h, t=24 h and t=96 h
Volume: 40 mL
Storage: Samples were stored in a refrigerator (2-8°C) until analysis.
Additionally, reserve samples of 40 mL were taken from all test solutions for possible analysis. If not already used, these samples were stored in a refrigerator (2-8°C) for a maximum of three months after delivery of the draft report. - Vehicle:
- no

- Key result
- Duration:
- 96 h
- Dose descriptor:
- LL50
- Effect conc.:
- > 100 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mortality (fish)
- Remarks on result:
- other: the 96h-LL50 was above 100% of a saturated solution prepared at a loading rate of 100 mg/L
- Details on results:
- No mortality or clinical effects were observed at the limit concentration and the control during the test period. The responses recorded in this test allowed for reliable determination of an LL50. The responses recorded in 100% of the SS were in agreement with the results of the range-finding test.
- Results with reference substance (positive control):
- Under the conditions of the present test, all carp exposed to a PCP concentration of 0.46 mg/L died within 24 hours, while no mortality occurred at 0.10 and 0.22 mg/L. The 96h-LC50 for carp exposed to PCP was 0.32 mg/L (95 % confidence interval between 0.22 and 0.46 mg/L). This effect was already reached within 24 hours of exposure.
- Validity criteria fulfilled:
- yes
- Conclusions:
- Under the study conditions, the 96h-LL50 of the test substance in carp was above 100% of a saturated solution prepared at a loading rate of 100 mg/L.
- Executive summary:
A study was conducted to determine the acute toxicity of the test substance, mono- and di- C12-18 PSE, Na+, to fish according to OECD Guideline 203 and EU Method C.1, in compliance with GLP. Seven fish (Cyprinus carpio) per group were exposed to a control and to 100% of the saturated solution (SS) of the test substance. The total exposure period was 96 h and the experiment was realised under static conditions. Due to the complex nature of the test substance, specific analyses proved to be difficult to obtain and it was decided to analyse the Total Organic Carbon (TOC) concentration as a surrogate measure. Samples for TOC concentrations were taken at the start and after 24 and 96 h of exposure. The TOC analysis performed on samples taken from 100% of the SS were regarded as indicative because of the low carbon concentrations. Effect parameters were based on the percentages of the saturated solution prepared at a loading rate of 100 mg/L. No mortality or clinical effects were observed at the limit concentration and the control during the test period. The responses recorded in this test allowed for reliable determination of an LL50. The study met the acceptability criteria prescribed by the study plan and was considered valid. Under the study conditions, the 96 h-LL50 of the test substance was above 100% of a saturated solution prepared at a loading rate of 100 mg/L (Bouwman, 2017).
