In the test vessels with a loading of 100 mg/L rhenium powder, average dissolved rhenium concentrations of 338 μg Re/L with a variation coefficient of 2% and of 390 μg Re/L with a variation coefficient of 4% were measured in the test medium at pH 6 and pH 8 respectively after a exposure of 24 h.
Applicant's summary and conclusion
- Conclusions:
- In the test vessels with a loading of 100 mg/L rhenium powder, average dissolved rhenium concentrations of 338 μg Re/L with a variation coefficient of 2% and of 390 μg Re/L with a variation coefficient of 4% were measured in the test medium at pH 6 and pH 8 respectively after a exposure of 24h.
- Executive summary:
The experiments of the study (dissolution characteristics of rhenium powder) have been performed according to the instructions of the OECD Test Guideline No 29 (2001), the study plan and the SOPs to be applied. The determination of the concentration of dissolved rhenium has been delegated to the ISO 9001:2008 accredited Test Site CANMET-MMSL, Canada.
The pH measured in the test media and in the blank and test item vessels at pH 6 and pH 8 varied from 5.99 to 6.02 and from 7.96 to 8.00. All measured data were within the specifications of ± 0.2.
The measured dissolved oxygen concentrations in the test medium and in the blank controls and test vessels at pH 6 and 8 varied between 8.39 and 8.55 and were higher than the value of ± 6 mg O2/L which is considered as 70% of the saturation concentration in contact with the air.
The concentration rhenium (Re) in the test media and in the blank control vessels at pH 6 and pH 8, were always below the limit of detection (0.1 μg Re/L).
In the test vessels with a loading of 100 mg/L rhenium powder, average dissolved rhenium concentrations of 338 μg Re/L with a variation coefficient of 2% and of 390 μg Re/L with a variation coefficient of 4% were measured in the test medium at pH 6 and pH 8 respectively after a exposure of 24h.
Based on the results of the experiments we may conclude that rhenium showed dissolution above detection limit and therefore, may be important in the design of a full test with the objective for classification purposes according to the EU-CLP and UN-Globally Harmonized System. However, as the level of dissolution in the screening study is well below the ERV a full T/D test is not required for this substance.
