Description of key information
Additional information
Due to the inorganic character of the substance and the absence of chemical groups susceptible to hydrolysis biodegradation is not a concern. Elemental sulphur which is partially leached out by water and dissociates forming HS−, HSO4−and SO4=the species that predominate in the environment that might be found in nature. However, the elemental content of sulphur in the ferronickel slag is not significant (maximum 0,6 w/w %) therefore is not expected pH contribution to the local environment from the sulphur ions, which are integrated into the various mineral species present in the environment.
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.
