Additional information

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