PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Green liquor sludge is primarily an inorganic UVCB substance. PBT/vPvB properties are relevant only for organic substances/constituents. Green liquor sludge contains small quantities of organic constituents from wood raw material and from incomplete burning processes of black liquor fuel.
Green liquor is known to contain < 0.1 % organic PAH trace constituents, some of which may be classifiable as PBTs. However, the concentration of these PAHs remain at very low 0.0001 % wt. level and therefore green liquor sludge need not to be classified as a PBT/vPvB substance.
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.
