Applicant's summary and conclusion
- Conclusions:
- Amorphous barium copper zinc borobismuthate was measured for Bi, Cu and Zn solubility in a 24 h transformation/dissolution test at pH 6 and pH 8.
The highest concentration of Bi was 83.68 ug/L (pH 8) after 24h.
The highest concentration of Cu was 5.54 ug/L (pH 6) after 24h.
The highest concentration of Zn was 40.01 ug/L (pH 8) after 24h.
The highest concentration of Bi was 51.55 ug/L (pH 6) after 7d.
The highest concentration of Cu was 5.53 ug/L (pH 8) after 7d.
The highest concentration of Zn was 33.18 ug/L (pH 8) after 7d.
The highest concentration of Bi was 6.2 ug/L (pH 6) after 28d.
The highest concentration of Cu was 6.05 ug/L (pH 8) after 28d.
The highest concentration of Zn was 40.74 ug/L (pH 8) after 28d. - Executive summary:
Table below compares the acute and chronic ERVs for Zn and Cu in the EU with the 7 and 28 d release rates measured by the transformation dissolution protocol for a dosing of 1 mg/l at pH 8.
The values in green would correspond with no hazard classifications, Acute and Chronic, due to a lower TDp release than the corresponding ERVs values.
