Sampling and analysis
- Analytical monitoring:
- yes
- Details on sampling:
- - Concentrations, sampling method, sample storage conditions before analysis:
Composite samples (about 150 mL in duplicate) of each test concentration were drawn by mixing identical volumes of the test solutions taken from the approximate center of the test vessels. They were taken immediately before exposure and after 48 hours exposure and kept at - 18°C to - 22°C until analysis.
Test solutions
- Vehicle:
- yes
- Details on test solutions:
PREPARATION AND APPLICATION OF TEST SOLUTION (especially for difficult test substances)
- Method: 2 g of the test substance were mixed with 18 g of a water solution containing 0.4% lecithin and then diluted at 1 : 100
- Controls: Blank, water and 3.6 mg lecithin/L
- Chemical name of vehicle (organic solvent, emulsifier or dispersant): lecithin
- Concentration of vehicle in test medium (stock solution and final test solution): 4 %
- Evidence of undissolved material (e.g. precipitate, surface film, etc): at the start of exposure small parts of the test substance were observed at the surface of the test solution at test concentrations of nominal 58 and 100 mg/L. A slight deposit was observed at nominal 10 - 58 mg/l and a strong deposit at nominal 100 mg/l at the end of exposure.

- Details on test organisms:
- TEST ORGANISM
