Any other information on results incl. tables
The pH measured in the medium at the start of the test, and in the blank and test item vessels during the test varied from 6.01 to 6.05. All measured data were within the specifications of pH 6 ± 0.2. For the test at pH 8 the pH moved from 7.95 at the start of the test to 7.29 after 24 hours of extraction and so didn’t meet the ± 0.2 criterion.
The measured TOC of the medium was below the reporting limit of the analytical laboratory ( <1 mg C/L), and so fulfilled <2 mg C/L criterion as laid down in the OECD Guidelines.
The temperature of the test solutions fluctuated between 21.5 and 22.8°C and corresponded to the required test conditions of 20 – 23°C.
The dissolved oxygen concentration measured in the blank and test item vessels varied from 8.39 to 8.48 mg O2/L. These values were higher than the target value of ± 6 mg O2/L at 22°C which means more than 70% of the saturation concentration was in contact with the air (± 8.5 mg O2/L).
The test medium at the start of the test and the blank control vessels during the test showed no significant concentrations of copper.
For the test at pH 6 at a loading of 100 mg/L Copper(I) iodide an average dissolved copper concentration of 3643 ± 49 µg Cu/L was found.
For the test at pH 8 at a loading of 100 mg/L Copper(I) iodide an average dissolved copper concentration of 2201 ± 34 µg Cu/L was measured.
Based on the results of the experiments we may conclude that pH 6 is the pH were the highest copper concentrations were measured.
