Materials and methods
- Principles of method if other than guideline:
- The report aims to describe the transformation/dissolution behaviour of copper intermediates through an experimental design that follows the recommendations of the OECD guidance document on transformation/dissolution (T/D) (OECD 2001) and the standard operating procedures (SOP) proposed by CANMET and LISEC for the Transformation / Dissolution protocol to the ad hoc OECD Validation Management Group (VMG) . The developed procedures, called SOP, provide a detailed methodology for T/D that includes instrumentation requirements, reagents quality, procedures for the seven-day and 28-days full test, chemical analyses and a quality assurance program (QA/QC standards).
The methods consists of a standardized shaking in "environmental relevant media" and sampling/measuring of the soluble metal ions at regular time intervals
The results of T/D tests can be compared with the eco-toxicity reference values to establish the aquatic hazard classification of the tested substance. - GLP compliance:
- no
- Remarks:
- other quality assurance
- Type of study / information:
- In accordance to CLP guidance chapter IV. The metal concentration released during the transformation/dissolution test are needed for a read-across of the ecotoxicity expressed as soluble metal ions (obtained from ecotoxicity tests with soluble metal compounds) to the ecotoxicity of the insoluble metal bearing materials (target substance).

Applicant's summary and conclusion
- Conclusions:
- The data are of good quality and critical to the assessment of the environmental hazards of the intermediate
- Executive summary:
Transformation/dissolution tests of B1 copper intermediates, anode copper, in 1 – 2 mm granules and massive form, were carried out to study its potential to release metals to the environment, in the context of the EU classification and labelling and REACH regulations.
Considering the composition of this complex material, a transformation / dissolution test was performed for 7 days at pH 6 and a loading of 100 mg/L, following the release of a broad range of metals from the samples. The results of the 7 days test for the 6 samples, identified by the European Copper Institute as B1, samples- Type I to Type IV, showed a copper release to the OECD media between 47 and 87 µg/L.
Only minor releases are recorded for some of the other metals: lead, nickel or arsenic (0 -10 µg/L). The sample 09TT03187 (Type IV, secondary anode) is an exception, with Lead and Nickel concentrations in the OECD media of 56.8 and 14.2 µg/L, respectively.
To assess the extrapolation of the results to all samples, across the industry the relative releases of respectively Cu, Pb, Ni were calculated as % metal released / % metal present (= potential release) at pH 6, during 7 days transformation/dissolution. The following values are recorded:
o Cu: 0.05 to 0.09%
o Ni: 0.06 to 0.3%
o Pb: 0.8 to 1 % except for the one secondary blister 09TT03187with 6.3% release
o As : 0.2 to 0.7%
