Additional information
For the evaluation of this endpoint data from two handbooks (CRC handbook and Merck index) and one database (Gestis database) were used as a weight of evidence.
According to ECHA, guidance on information requirements and chemical safety assessment – chapter R.7a, specific handbook data for physic-chemical properties are considered to be a reliable data source. Useful reference books and data compilations containing peer reviewed physico-chemical data include the Merck Index and the CRC Handbook of Chemistry and Physics.
Data available from these handbooks describe dibismuth trioxide as a yellow poder or monoclinic crystalline substance with no specific odour.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
