Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
In the assessment of the ecotoxicity of this bismuth substance, a read-across approach has been used based on all information available for bismuth compounds. This grouping of bismuth compounds is based on the assumption that properties are likely to be similar or follow a similar pattern as a result of the presence of the common bismuth moiety. For most metal-containing compounds, it is the potentially bioavailable metal ion that is the moiety of toxicological concern. The ecotoxicity results selected for read-across among bismuth substances are all based on bismuth subnitrate, dibismuth trioxide or bismuth metal powder.
Conclusion on classification
The results triggered no classification under the CLP Regulation (EC No 1272/2008). No classification for environmental effects is therefore required.
The substance is therefore proposed to be “not classified” and appropriate comments are detailed within Section 2 of the registration dossier.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
