Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Rationale for read-across:
In soil as well as in sediment-water systems, dolomite calcined will react and release calcium ions, magnesium ions and hydroxyl ions. Therefore, relevant information on adsorption/desorption of dolomite calcined can be broadened to data on adsorption/desorption of calcium and magnesium. The behaviour of hydroxyl ions depends on the pH buffer capacity of the tested medium. The pH buffer capacity is controlled by a whole range of processes (mineral dissolution/precipitation, protonation/deprotonation of pH dependent charge sites, reaction with CO2, biological processes etc.) and as such, Kd values are not relevant for the fate and behaviour of OH- in soils or sediment.
