Test solutions
- Vehicle:
- no
- Details on test solutions:
- PREPARATION AND APPLICATION OF TEST SOLUTION (especially for difficult test substances)
- Method: The test solutions were prepared separately for each test concentration, following general
guidance provided in OECD 23, as the test substance is a UVCB.
The test substance was weighed in and made up with test medium to reach the
nominal concentrations of 0, 4.8, 8.6, 15.4, 27.8 and 50 mg/L.
Undissolved test substance was removed by twofold filtration with a membrane filter
(pore size 0.2 μm).

Results and discussion
Effect concentrations
- Duration:
- 48 h
- Dose descriptor:
- EC50
- Effect conc.:
- 11.6 mg/L
- Nominal / measured:
- meas. (geom. mean)
- Conc. based on:
- test mat.
- Basis for effect:
- mobility
- Details on results:
- The measured concentrations (geometric mean) of the main constituent of the test substance in the test water were in a range of 40-64% of the nominal concentrations. This was most likely due to limited
solubility of the test substance in the test medium, and an additional decrease of the test substance over 72 h. Moreover, the test substance is a UVCB and as such every constituent contributes to a different degree to overall solubility, depending on its own individual solubility and its mass fraction in the test substance. Thus, for an evaluation of the results the nominal concentrations should be used and were considered to be an accurate representation of exposure levels throughout the experiment.
