Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
During the production and the industrial use of dibismuth trisulfide there is no release into the waste water. Therefore, an input via sludge application on agricultural soil is considered to be negligible. In addition, bismuth and bismuth compounds are not listed on the list of regulated heavy metals in the EEC directive 86/278/EEC on the protection of the environment, and in particular of the soil, when sludge is used in agriculture.
The vapour pressure of this inorganic compound is expected to be very low and particles tend to agglomeration and disposition on surfaces, thus, also the exposure via air is considered to be negligible.
Acute tests on water organisms of three trophic stages showed no toxicity up to limit concentration. Moreover, no inhibition of activated sludge respiration up to limit concentration was observed.
Taken together, due to the ecotoxicological data on water organisms and activated sludge it is concluded that tests on terrestrial organisms, plants and microorganisms will not provide additional information for the ecotoxicological risk assessment. Moreover, the exposure via different pathways is limited. Consequently the terrestrial studies are waived.
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.
