Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The acute fish toxicity, acute Daphnia toxicity, algae toxicity and ASRI studies were all conducted with bismuth subnitrate.

In the assessment of the ecotoxicity of this bismuth substance, a read-across approach has been used for some endpoints 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 are based on dibismuth trioxide and 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.
