【摘要】 采用等离子体质谱(ICPMS)法对三峡地区及长江下游地区出土的古墓中的人体骨骼中的微量元素Zn、Sr、Ba、Ca进行了分析,并与原子吸收光谱(AAS)对照,结果表明ICPMS是骨化学微量元素分析很好的方法,它相对FAAS,具有灵敏度高,检出限低,可快速进行多元素检测等优点,对溶液中元素的检出限可达到ng/L数量级,对元素的高含量和低含量都能进行准确测量。本实验以Zn、Sr、Ba、Ca为指示剂,根据其测量结果,还对上述两地区的古人类食谱进行了初步探讨。更多还原

【Abstract】 Inductively coupled plasma mass spectrometry (ICP-MS) was used to detect trace elements in ancient human bones from Sanxia and lower areas of Yangzi river. The results show that ICP-MS is a powerful technology in the analysis of bone chemistry. Compared with flame atomic absorption spectrometry (FAAS), ICP-MS is much more sensitivity. The limit of detection to elements in solution can be up to ng/L level. And the method can accurately detect both of high concentration elements and low concentration elements at the same time. Using Zn, Sr, Ba, Ca as indicators, some paleodietary information were obtained from the ~analytical results.更多还原
