Any other information on results incl. tables
The quantification of the ammonium of the test item was performed using ion chromatography with conductivity detection (IC-CD).
At the start of the test 98%of the nominal test concentration was found. After 48 hours test duration, 93% of the nominal value was determined. During the test the Daphnia were exposed to a mean of 95 % of nominal. Therefore, all reported results refer to nominal concentrations.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- The toxic effect of the test item Ammoniumhexafluorosilicate to Daphnia magna was assessed in a static limit-test. The 48-hour NOEC was determined to be >= 100 mg test item/L. The 48-hour LOEC was determined to be > 100 mg test item/L The 48-hour EC5o value was determined to be > 100 mg test item/L.
- Executive summary:
The purpose of this study was to evaluate the influence of the test item Ammoniumhexafluorosilicate on the mobility ofDaphnia magna.Young daphnids (< 24 hours old) were exposed in a static test for 48 hours to test water containing the test item at the concentration of nominal 100 mg test item/L. This limit test was performed in compliance with the test guidelines to demonstrate that the test item has no toxic effect on daphnids up to at least the test concentration of 100 mg test item/L.
