[Lead and arsenic resorption in the hard tissues (crystallochemical studies)].
Histologic-analytical observations on the resorption of lead and arsenic compounds are put into relationship with crystal-chemical analogies in the composition of hard tissue and the structure of calcium phosphate apatites with lead and arsenic substitution. Chemical analyses and x-ray diffraction of calcium and lead apatites with phosphate and arsenate represented as mixed precipitates in solution equilibrium show that - with the exception of calcium arsenate apatite - linear diadochocinetic substitution conditions are existing. The composition of calcium arsenate apatite is clearly shown to contain much less arsenic. This result is explained by the crystallographic laws of substitution in the crystal lattice (diadochocinetic laws). The clinical and physiological findings in lead and arsenic resorption are confirmed by the found distributional equilibria.
