Calcium oxide - Wikipedia

Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound.It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term "lime" connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate.

Calcium-dependent cyto- and genotoxicity of nickel …

The authors speculated on the mechanisms by which divalent ions such as Ni 2+ enter cells and suggested that calcium channels may be transducers of Ni due to metal ion ‘mimicry’. The involvement of Ca 2+ signaling in the present model appeared plausible since we noted an increase in intracellular Ca 2+ as a result of the Ni exposures.
