Post-mortem uptake of trace metals into bone

Post-mortem uptake of trace metals into bone 

Three main mechanisms have been proposed for introduction of metal cations into bone, and each may play a part in incorporation of certain trace metals into bone under differing environmental conditions  

Adsorbtion of metal cations onto crystal surfaces (presumably displacing surface calcium). 

Growth of discrete trace metal-phosphate phases disseminated within the bone. 

Direct substitution of cations in pore waters for Ca in the apatite lattice is a third
