Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
GLS in particulate form is immobile in soil and sediment. GLS is rich in calcium and carbonate, unburned coal and sodium. Calcium carbonate (“calcite” in pure crystalline form) is poorly soluble in water but reacts with strong acids, releasing carbon dioxide. Calcium carbonate reacts with water saturated with carbon dioxide and forms soluble calcium hydrogen carbonate (Ca(HCO3)2 “bicarbonate”. CaCO3(s) + CO2+ H2O <-> Ca(HCO3)2
Adsorption/desorption behavior of dissolved constituents is governed mainly by inorganic soil and sediment materials. Each constituent behave by a characteristic way depending highly on local environmental conditions. Generally the adsorption of the ionic constituents to organic materials is weak and adsorption to minerals is stronger and more pronounced. Adsorption/desorption of calcium and sodium and consequently their mobility and bioavailability is much related to the soil cation exchange capacity (CEC).
Key value for chemical safety assessment
Additional information
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.
