传统上，法医土壤样本是通过物理或化学方法检查颜色、质地和矿物质含量来分析的。这些方法没有检查任何有机或水溶性组分。一系列分析技术已应用于该领域，并且最近对这些程序进行了审查。本研究使用拉曼光谱来评估土壤样品中的矿物和水溶性有机部分。土壤样本是从城市和农村环境中收集的，包括英格兰布拉德福德市和林肯郡的一个耕地农业区。这项研究展示了如何通过使用氧化制备方法，拉曼光谱可以利用矿物学成功区分土壤类型以及土壤的有机部分和水溶性部分。版权所有 (C) 2011 John Wiley & Sons, Ltd.
Forensic soil samples have been traditionally analysed via examinations of colour, texture and mineral content by physical or chemical methods. These methods leave any organic or water-soluble fractions unexamined. A range of analytical techniques have been applied in this area and these procedures have been reviewed recently. This study uses Raman Spectroscopy to assess both the mineralogical and the water-soluble organic fractions in soil samples. Soil samples were collected from both urban and rural environments comprising the city of Bradford, England, and an arable farming district in Lincolnshire. This study demonstrates how, with the use of oxidative preparation methods, Raman spectroscopy can be used to successfully discriminate between soil types using mineralogy as well as the organic and water-soluble fractions of soils.
