- experimental study
- Adequacy of study:
- key study
- Study period:
- September-October 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- 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:
- not applicable
- Principles of method if other than guideline:
- OECD 29 (2001) is a guidance document on transformation/dissolution of metals and metal compounds in aqueous media. The protocol included in the guidance is being considered for formal validation.
An experiment based on the 'dissolution screening test - sparingly soluble metal compounds' as described in OECD 29 (2001) was performed. Nominal substance concentrations of 1 mg/L were agitated for 24 hours (at pH 1) or 28 days (at pH 7) with aqueous dissolution media. After centrifugation, a sample from each test solution was analysed for bismuth by ICP analysis. - GLP compliance:

- Conclusions:
- An experiment based on the 'dissolution screening test - sparingly soluble metal compounds' as described in OECD 29 (2001) was performed. Nominal substance concentrations of 1 mg/L were agitated for 24 hours (at pH 1) or 28 days (at pH 7) with aqueous dissolution media. After centrifugation, a sample from each test solution was analysed for bismuth by ICP analysis. At pH 7, the amount of (dissolved and/or dissociated) bismuth is below the limit of detection. This corresponds with a substance concentration of < 8 µg/L. At pH 1, very small amounts of (dissolved and/or dissociated) bismuth were measured corresponding with a substance concentration of 154 µg/L. Based on all results the water solubility of the substance was concluded to be very low (< 0.1 mg/L).

Description of key information
The water solubility of the substance was visually determined to be < 1 mg/L at 20°C.
From the results of an experiment based on the 'dissolution screening test - sparingly soluble metal compounds' as described in OECD 29 (2001) it can be concluded that the water solubility of the substance is very low. At pH 7, the amount of (dissolved and/or dissociated) bismuth is below the limit of detection. This corresponds with a substance concentration of < 8 µg/L. At pH 1, very small amounts of (dissolved and/or dissociated) bismuth were measured corresponding with a substance concentration of 154 µg/L.
Key value for chemical safety assessment
Additional information
The water solubility of 3 different batches of the substance was visually determined. With all 3 batches, the same result was obtained.
