Is consumption of chlorine harmful to bones ?

I know fluorine consumed with water can cause fluorosis to bones and joints.

Can chlorine, a similar halogen like fluorine, also cause damage to bones and bone joints?

• Are you talking about chlorine gas or the chlorine ion? – CoffeeIsLife Jun 3 '17 at 9:16

• I'm voting to close this question as off-topic because the OP wishes to know the medical complications associated with the "consumption of chlorine". I second what @porphyrin said: This question is better suited on the Health.SE. – paracetamol Jun 11 '17 at 6:45

Bones are largely composed of calcium compounds (mainly hydroxyapetite, $\ce{Ca5(PO4)3(OH)}$). The calcium salts of bone are very slightly soluble, and thus they are in an equilibrium between the solid form and the dissolved aqueous form. Because calcium fluoride is extremely insoluble, fluoride can displace the naturally occurring anions to form water-insoluble calcium fluoride. This results in weaker, more easily fractured bones, which is the condition known as skeletal fluorosis.
