Abstract
An X-ray fluorescence analysis study of iron, zinc, rubidium, strontium, and lead in ashed vertebral column whole bone samples of 51 sudden death victims in Western Australia gave median values of 893, 213, 25,108, and 25 ppm, respectively. Highly significant concentrationage Spearman correlations were observed for iron-age (r s = 0.45, P< .004), Zn-age (0.43, P< .006), and lead-age (0.63, P< .001), the mean per annum rates of increase being 26, 0.4, and 0.8 ppm, respectively, and marked concentrationconcentration correlations were found for iron-lead (0.44, P< .01) and zinc-lead (0.29, P< .10). Other notable correlations are the concentration-sex values for zinc (-0.47, P< .003) and strontium (0.30, P < .06). The median zincconcentrations for the male and female subsets are 216 and 205 ppm, respectively; the corresponding values for strontium are 100 and 120 ppm.
