A comparison of the distribution of some halide ions in the body

The distribution of the halide ions F −, Br −, I − and tentatively Cl −, and the pseudo-halide ion SCN − has been studied in mice and rats. Whole body autoradiography, microautoradiography, double tracer autoradiography, and scintillation counting methods have been used. Similarities and dissimilarities in the distribution pattern of the various ions are described and discussed. Although the chemical and physical properties are similar for the elements studied—with some notable exceptions for fluorine—their distribution patterns in the body show pronounced dissimilarities.
