Sampling and analysis
- Analytical monitoring:
- yes
- Details on sampling:
- - Concentrations:
* 0 mg/l (control)
* 1.00 mg/L of test item
* 3.16 mg/L of test item
* 10.0 mg/L of test item
* 31.6 mg/L of test item
* 100 mg/L of test item
- Sampling method:
Each loading level and the control will be analytically verified via HPLC-DAD at least at the start of the exposure (0 hours).
At the start of exposure (0 hours), sampling was carried out after preparation of the loading levels.
At test start the measured test item concentrations were below the LOD in all loading levels. Therefore no analytical monitoring was carried out at the end of exposure (72 hours), all test loadings can be considered to be below the LOD in the aged media too and the method was not validated.
- Preparation of samples: The control and all samples were analysed undiluted.
- Sample storage conditions before analysis: all samples were stored at 6 +/- 2°C until the start of the analysis, if necessary. Pepared samples were stored in the autosampler at room temperature until analysis.

- PREPARATION AND APPLICATION OF TEST SOLUTION (especially for difficult test substances)
- Method:
*Water Accommodated Fraction: In view of the difficulties associated with the evaluation of aquatic toxicity of poorly water soluble test items, a modification of the standard method for the preparation of aqueous media was performed. An approach endorsed by several important regulatory authorities in the EU and elsewhere (ECETOC 1996 and OECD 2000), is to expose the organisms to a Water Accommodated Fraction (WAF) of the test item in cases where the test item is a complex mixture, an UVCB substance and is poorly soluble in water and in the permitted solvents.
Using this approach, aqueous media will be prepared by mixing the test item with water for a prolonged period sufficient to ensure equilibration between the test item and the water phase.
*Preparation of the WSF: Five water accommodated fractions (WAFs) were prepared with a nominal loading of the test item of 1.00 - 3.16 - 10.0 - 31.6 - 100 mg/L(spacing factor √10). The loading levels are based on the results of a preliminary range finding test. For each loading level, an appropriate amount of the test item was weighed out. The test item was applied onto a glass slide. The glass slide with the test item was inserted in a glass flask with an appropriate amount of demineralized water. These dispersions will be shaken at 20 rpm for 24 hours at room temperature. Undissolved particles will be removed by membrane filtration (membrane filter 0.20 µm, RC, MACHEREY-NAGEL). The filter was saturated in order to avoid adsorption during the filtration. The first 25 mL of the filtrate will be discarded. The filtration was interrupted for 15 minutes to allow adsorption and saturation of the filter material with dissolved test item. Thereafter, the filtration was continued. The next 25 mL were discarded. The following water soluble fractions (WSFs) were used in the test. During filtration, the filter was always be kept covered. The solutions were checked via laser beam (Tyndall effect) for undissolved test item.The Tyndall effect was negative. The components of the dilution water were added to the WSFs.
Replicates: 3 replicates per loading level.
- Controls: 6 replicates (without test item) will be incubated under the same test conditions as the test item replicates.

*Chlorophyll a-fluorescence: The cell density was measured daily via chlorophyll a- fluorescence, excitationat 436 nm, emission at 685 nm. Fluometer: Microplate Reader chameleon V (HIDEX) with software Micro Win 4.41 (MIKROTEC LABORSYSTEME GMBH) No self-fluorescence was found in the preliminary range finding test at the loading level of 100 mg/L.
- Microscopic evaluation: Microscopic evaluation of the cells at the start and the end of exposure was carried out. The cells were checked for unusual cell shapes, colour differences, differences in chloroplast morphology, flocculation, adherence of algae to test containers and agglutination of algae cells.
