The control concentration (T=0) was below detection limit for the whole experiment for all treatments.
Tests were of satisfying repeatability (Coeficient of Variation 5 -12% at 7d; 5% with 1mg L loading at 28 days).
The dissolution was proportional to loading at 1 mg/l and 100mg/l loading. For 10mg/l, a lower dissolution was observed. The higher dissolution rates were used for the assessment.
Applicant's summary and conclusion
- Conclusions:
- Test results of good quality and relevant for assessing the transformation/dissolution of metallic cadmium in aqueous solutions according to OECD.
- Executive summary:
The transformation/Dissolution of cadmium metal in massive form was assessed in a standard T/D test according to OECD, under conditions maximizing solubilisation (pH 6).
The dissolution was proportional to loading at 1 mg/l and 100mg/l loading. For 10mg/l, a lower dissolution was observed. The higher dissolution rates were used for the assessment.
