- OECD Series on Testing and Assessment No. 29 (23-Jul-2001): Guidance document on transformation/dissolution of metals and metal compounds in aqueous media
- Version / remarks:
- 2001
- Deviations:
- yes
- Remarks:
- Bioaccessibility testing: loading of 100 mg/L; five artificial physiological media agitated at 100 rpm, at 37 °C ± 2 °C; sampling after 2h and 24h; determination of antimony, tin and vanadium concentrations after filtration by ICP-OES and ICP-MS.
- Principles of method if other than guideline:
- The test was performed on the basis of OECD Series on Testing and Assessment No. 29 as well as according to the bioaccessibility test protocol provided by the monitor. The bioaccessibility protocol has been developed on the basis of relevant published methods ([1], [2], [3], [4] and [5]).
The aim of this test was to assess the dissolution of the pigment IPC-2018-003 (tin antimony grey cassiterite) in the artificial physiological media GST, GMB, ALF, ASW and PBS. The test media were selected to simulate relevant human-chemical interactions (as far as practical), i.e. a substance entering the human body by ingestion or by inhalation.
Five different artificial physiological media with a single loading of test substance of 100 mg/Lwere used. The measurement of dissolved antimony, tin and vanadium concentrations after filtration were performed by ICP-OES and ICP-MS. Samples were taken after 2 and 24 hours agitation (100 rpm) at 37 ± 2 °C. The study was performed in triplicate with two additional method blanks per medium.

- Test principle in brief:
- five different artificial physiological media,
- single loading of test substance of 100 mg/L,
- samples taken after 2 and 24 hours agitation (100 rpm) at 37 ± 2 °C,

The aim of this test was to assess the dissolution of IPC-2018-003 (tin antimony grey cassiterite) in five artificial physiological media: Artificial lysosomal fluid (ALF, pH = 4.5), Artificial sweat solution (ASW, pH = 6.5), Gamble´s solution (GMB, pH = 7.4), Artificial gastric fluid (GST, pH = 1.5), Phosphate buffered saline (PBS, pH = 7.4). The test media were selected to simulate relevant human-chemical interactions (as far as practical), i.e. a substance entering the human body by ingestion into the gastrointestinal tract and by inhalation.

- Reagents
The water (resistivity >18 MΩ·cm.) used for this test was purified with a Pure Lab Ultra water purification system from ELGA LabWater, Celle, Germany.
- Nitric acid - “Supra” quality (ROTIPURAN® supplied by Roth, Karlsruhe, Germany).
- Hydrochloric acid – “instra-analyzed plus” quality (J.T. Baker, Griesheim, Germany).
- Sodiumhydroxide – pro Analysis quality (Chemsolute, Th. Geyer, Renningen, Germany)
Metal analysis
- Standards: single element standards were used as antimony, tin and vanadium standards (Merck Certipur Antimony ICP standard 1000 mg/L lot no. HC384311; Merck Certipur Tint ICP standard 1000 mg/L lot no. HC375770; Merck Certipur Vanadium ICP standard 1000 mg/L lot no. HC43452566; Darmstadt, Germany).
- Certified reference materials: quality control standards TM-25.4 (lot no. 0914) obtained from Environment Canada and multielement standards (Merck XVII, lot no. HC382226 – only antimony and tin; Merck XXI, lot no. HC42984673 – only vanadium, Darmstadt, Germany) were analyzed for total dissolved antimony, tin and vanadium by ICP-MS along with the samples to determine the accuracy of the applied analytical method. Furthermore the calibration solutions were measured along with the ICP-MS measurements as recalibration standards.
Instrumental and analytical set-up for the ICP-MS instrument:
Agilent 7700ce ICP-MS, Agilent Technologies, Waldbronn Germany
Nebulizer: Conical nebulizer, from Glass Expansion
Spray chamber: Scott Type spray chamber, from Agilent
Carrier gas flow: 0.93 L/min

RF power: 1500 W
Isotopes: 121Sb, 123Sb, 118Sn, 119Sn, 120Sn, 51V and 103Rh (internal standard)
The applied LOD/LOQs were calculated as follows:
LOD: 3 x standard deviation of calibration blank divided by the slope of calibration line;
LOQ: 3 x LOD.
Calibration: blank, 0.1 μg/L, 0.25 μg/l, 0.5 μg/L, 0.75 μg/L, 1 μg/L, 2.5 μg/L, 5.0 μg/L, 7.5 μg/L, 10 μg/L, 12.5 μg/L, 15 μg/L, 17.5 μg/L, 20 μg/L, 22.5 μg/L and 25 μg/L.

Correlation factors (r): at least 0.999047
Determination of mass balance
To the residual, undissolved test item in the vessels, 80 mL aqua regia (3 : 1 mixture of concentrated hydrochloric and nitric acid) were added to the flasks after the test. The filters used for sampling were extensively rinsed with aqua regia. Solutions were sampled after at least 24 h, antimony, tin and vanadium were measured in at least one mass balance sample (vessel and filter/syringes) for each medium by ICP-MS, and the mass balance was calculated. - Details on dosing and sampling:

#Solutions with concentrations below the LOD/LOQ were also fortified. However, a recovery of ± 15 % may not be realistic as concentrations in the original (unfortified) sample below the LOD may be lower than the noise ratio and concentrations below the LOQ are between the noise ratio and a real (quantifiable) signal. For solutions with concentrations below the LOD/LOQ, a recovery of ± 25 % - 30 % is more realistic.

- On the basis of OECD Series on Testing and Assessment No. 29 as well as according to a bioaccessibility test protocol, which has been developed on the basis of relevant published methods, the dissolution of the pigment IPC-2018-003 (tin antimony grey cassiterite) in the artificial physiological media (GST, GMB, ALF, ASW and PBS) with a single loading of 100 mg/L, agitation (100 rpm) at 37 °C ± 2 °C and sampling after 2 and 24 h, was determined. The measurement of dissolved antimony, tin and vanadium concentrations after filtration were performed by ICP-MS. The study was performed in triplicate with two additional method blanks per medium.
