摘要
氢、氧稳定同位素作为一类化学示踪物质,在地理科学、环境生态和法庭科学等领域均有应用。在法庭科学研究领域,指甲作为一种记录人在不同时段内摄入氢、氧稳定同位素情况的载体,在推断人的生活地域变化轨迹方面具有很大的潜力,具有广阔的应用前景。本文从氢、氧稳定同位素溯源的基本原理,人指甲中氢、氧稳定同位素前处理方法和检验方法,人指甲氢、氧稳定同位素溯源技术的法医学应用等方面展开综述,并对稳定同位素溯源技术的发展等方面做了简要展望。
As an emerging chemical tracer technology,the hydrogen and oxygen stable isotopes have a wide range of applications in geoscience,environmental ecology and forensic science.The fingernail,a new type of biomarker,possess a high evidence and application value in forensic science and its analytical potential is gradually being tapped.The paper conducted a review from basic principle of hydrogen and oxygen stable isotopes traceability,pretreatment methods and determination methods in human fingernails and the application in forensic science.Besides,a brief prospect was also given about its development.
