Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Bioaccumulation is not relevant for lime (chemical) hydraulic. In the aquatic environment and in soil, exposure to lime (chemical) hydraulic actually comes down to exposure to calcium and hydroxyl ions. There will be no intake of lime (chemical) hydraulic as such from water or soil, nor will lime (chemical) hydraulic prevail under its original form in the organisms. Moreover, both the intake of the essential element calcium and the internal pH (hydroxyl ions) of an organism are actively regulated (homeostasis).

Similarly, calcium carbonate dissociates into the calcium Ca2+and carbonate CO32-ions at environmental pH. These are essential to all living organisms (flora and fauna) and their intracellular and extra-cellular concentrations are actively regulated. Bioaccumulation is thus not expected or relevant.
