法庭科学中泥土物证检验的意义与方法

The Significance and Method of Soil Evidence Examination in Forensic Science

综述了通过物理、化学和生物学手段来检验泥土物证中无机成分、有机成分和生物物证的方法,以期更好地发挥泥土物证在案件侦破和法庭诉讼过程中的作用。

Soil is a complex system that exists on the surface of the earth.In criminal activities,soil material evidence is often left behind or transferred,so soil material evidence occupies a very important position in forensic science.Soil physical evidence generally has the characteristics of trace,complex composition and poor uniformity,which brings difficulties to the examination of soil physical evidence.In this paper,the methods of examining inorganic components,organic components and biological material evidence in soil material evidence by means of physical,chemical and biological methods are summarized,so as to better play the role of soil material evidence in case detection and court proceedings.
