Cortical human bone samples from three tightly dated components of a single Sicilian site were chemically analyzed employing the highly sensitive technique of inductively coupled plasma emission spectroscopy. Although the skeletons appeared to be excellently preserved, significant diagenesis was detected. Moreover, a majority of the elements tested showed no constant or linear variation over time, implying that diagenetic change tends not to be a predictable function of duration of interment. Variation among major long bones of a single skeleton was quite high, as was variation across the cortex. The latter may reflect chemical inhomogeneity in bone tissue or may be an artifact of postmortem change. The results demonstrate the hazards of unsuspected and unpredictable diagenesis, which must be controlled before reliable dietary inferences can be drawn.
利用电感耦合等离子体发射光谱这种高灵敏度技术，对来自西西里岛一个单一遗址三个年代测定精确的组成部分的人类皮质骨样本进行了化学分析。尽管这些骨骼看起来保存得极为完好，但仍检测到了显著的成岩作用。此外，大多数测试元素并未显示出随时间的恒定或线性变化，这意味着成岩变化往往不是埋葬时间的可预测函数。单个骨骼的主要长骨之间的差异相当大，皮质层之间的差异也是如此。后者可能反映了骨组织中的化学不均匀性，或者可能是死后变化的人为产物。结果表明了未被察觉和不可预测的成岩作用的危害，在得出可靠的饮食推断之前，必须对其加以控制。
