Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
STABILITY:
In accordance with EC 1907/2006, Annex VIII, point 9.2.2.1, column 2, hydrolysis investigations as a function of the pH are not required since the substance is basically insoluble in water.
BIODEGRADATION:
In accordance with column 2 of REACH Regulation (EC) No. 1907/2006, Annex VII, section 9.2.1.1, the studies on biodegradation does not need to be conducted as dibismuth trisulfide is an inorganic compound. This applies for the endpoints "biodegradation in water: screening tests", "biodegradation in water and sediment: simulation tests" and "biodegradation in soil".
In addition, in accordance with column 2 of REACH Regulation (EC) No.1907/2006, Annex IX ,section 9.2.1.2, 9.2.1.4 tests on "biodegradation in water and sediment" do not need to be conducted as dibismuth trisulfide is basically insoluble in water and neither direct nor indirect exposure is expected. The log Pow is not sufficient for an inorganic compound to estimate the potential of accumulation in sediment.
In addition, in accordance with column 2 of REACH Regulation (EC) No. 1907/2006, Annex IX, section 9.2.1.3, the study "biodegradation in soil" does not need to be conducted as neither direct nor indirect exposure of the soil compartment with dibismuth trisulfide is expected. The log Pow is not sufficient for an inorganic compound to estimate the potential of accumulation in soil.
BIOAKKUMULATION:
In accordance with EC 1907/2006, Annex VIII, point 9.3.2, column 2, bioaccumulation in aquatic species (water and sediment) is not required due to the fact that the substance has a log Kow of <<3, as an inorganic solid which is basically in soluble.
TRANSPORT AND DISTRIBUTION: ADSORPTION/DESORPTION:
The substance is an inorganic chemical and its Log Koc is considered arbitrarily as 0, i.e. the substance is considered mobile (worst case).
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.
