Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The particle size distribution study indicated a D50 of 5.16 µm for flue dust.
Additional information
The particle size distribution of flue dust was determined in an experimental study (Outotec 2010) using a laser diffraction system.
The study is not GLP, but followed sound scientific principles, is well documented and is considered suitable for use as a key study for this endpoint. Another sample of flue dust was tested (Johnson Matthey 2014) and the study measured a D50: 8.820 µm.
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.
