Applicant's summary and conclusion
- Conclusions:
- Under the conditions of the study, the concentrations of Mn, Co, Li and Ni measured in solution following a 7 day agitation period at the test material loading rate of 1 mg/L were 3.0, 2.6, 4.1 and 2.8 µg/L, respectively.
The concentrations of Mn, Co, Li and Ni measured in solution following a 7 day agitation period at the test material loading rate of 10 mg/L were 37.4, 40.5, 52.3 and 42.9 µg/L, respectively.
The concentrations of Mn, Co, Li and Ni measured in solution following a 7 day agitation period at the test material loading rate of 100 mg/L were 223.6, 254.0, 374.7 and 268.2 µg/L, respectively. - Executive summary:
The extent of transformation/dissolution of each individual constituent metal from the test material was investigated in a study which was conducted in accordance with the standardised guideline OECD 29.
A screening test was first conducted to ascertain the pH of maximum metal release. The test material was introduced into the aqueous media (pH 6, 7 and 8) at a single loading of 100 mg/L. After 24 and 48 hours of agitation, the dissolved metal ion concentrations were measured. The highest level of release of the metals was from the pH 6 solution and so the definitive study was conducted at this pH.
In the definitive study, three different test material loadings were investigated (1, 10 and 100 mg/L). The level of release of the metals was measured after a 7 day agitation period at all three loading rates.
Under the conditions of the study, the concentrations of Mn, Co, Li and Ni measured in solution following a 7 day agitation period at the test material loading rate of 1 mg/L were 3.0, 2.6, 4.1 and 2.8 µg/L, respectively.
The concentrations of Mn, Co, Li and Ni measured in solution following a 7 day agitation period at the test material loading rate of 10 mg/L were 37.4, 40.5, 52.3 and 42.9 µg/L, respectively.
The concentrations of Mn, Co, Li and Ni measured in solution following a 7 day agitation period at the test material loading rate of 100 mg/L were 223.6, 254.0, 374.7 and 268.2 µg/L, respectively.
