Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: OECD 29, 2001, Guidance on transformation /dissolution of metals and metal compounds in aqueous media
- Deviations:
- yes
- Remarks:
- mesocosm pond water used instead of standard media
- Principles of method if other than guideline:
- Transformation/dissolution behavior of copper slag was assessed through an experimental design that follows recommendations of the OECD 29 guidance document on transformation/dissolution (T/D) (OECD , 2001)
Release study was conducted on 5 different slag materials in 4 loadings for 7 days, stirring rate (100rpm).
As the study aim at “bridging” the results from the slag mesocosm study to other slag, copper smelting materials, the conditions of the copper slag mesocosm study (AUR-001/4-52) were adapted concerning water quality (mesocosm pond water, pH 8), and presence of basalt material.
Three basalt controls with the highest loading of 12500 mg/L were run additionally to two mesocosm water controls. All loadings of all slag materials were added by control basalt fines to a total loading of 12500 mg/L.
This test protocol is based on an experimental procedure of agitating various quantities of different slag crushed fines in control mesocosm water, and sampling and analyzing the solutions after filtration at specific time intervals to determine the concentrations of dissolved metal ions in the water. - GLP compliance:
- yes (incl. QA statement)
Test material
- Reference substance name:
- Slag, copper smelting
- IUPAC Name:
- Slag, copper smelting
- Details on test material:
- This test protocol is based on an experimental procedure of agitating various quantities of different slag crushed fines in control mesocosm water, and sampling and analyzing the solutions after filtration at specific time intervals to determine the concentrations of dissolved metal ions in the water.
Test materials were tested in bulk (original particle size) or crushed/sieved to 1-2 mm (massive materials) as follows;
3512 (bulk)
2987(bulk)
3821 (bulk)
5244 (1-2 mm, mesocosm reference sample)
3181 (1-2mm)
The materials were selected based on the following criteria, applied to the hazard characterisation of the various slags:
-Selection of different material types produced by the industry (granules, stones, fines)
-Selection of materials produced during primary and secondary copper productions
-Selection of materials with relative high measured metal releases during 7 days transformation/dissolution tests, carried out at pH 6 and a loading of 100 mg/l , standard media (Rodriges et al, 2010)

Applicant's summary and conclusion
- Conclusions:
- The data are of good quality and critical for extrapolation from slag used in mesocosm study to other slags
- Executive summary:
Transformation/dissolution test (7 days, 4 loadings, pH around 8) was carried out using a range of slags exposed to the water used for a meosocosm ecotoxicity study on one slag material.
The following metal releases (µg/g slag material) were observed corrected by subtraction of basalt control concentrations The metal releases are expressed per gram slag material.
Cu 2.1 – 63.07 µg/g
Zn 1.2 – 21.8 µg/g
Pb 1.2 – 1.3 µg/g
Ni 0.6 – 6.5 µg/g
The data indicate usually lower release rates from the slags then the ones observed during the classic T/D tests at pH6 (Rodriguze et al., 2010). The difference in solubility could not be entirely explained by differences in pH. Other differences, such as slag-specific characteristics (eg particle sizes and crystalline structure) and medium-specific characteristics (eg DOC) may be responsible for the observed differences among materials and test media.
