土壤是微量物证的一种。土壤的证据价值在于它本身组成部分的复杂性,如物理性质上在颜色、密度、粒径方面的差异,化学性质上在各元素含量方面的差异以及在地质学上矿物组成的差异等等。通过对土壤的这些复杂特性的分析检验我们可以区分不同地区的土壤。在实际工作中发现,很多犯罪现场都存在土壤物证。对犯罪现场泥土的分析检验,可以为查找第一犯罪现场,判断犯罪现场内的活动及侦查破案提供更多的线索和依据。
Soil is a kind of trace evidence. The evidence for soils lies in the complexities of its own components, such as physical differences in color, density, particle size, chemical differences in elemental content, and differences in geologic mineral composition, to name but a few. By analyzing these complex characteristics of soils we tested that we can distinguish soils from different regions. In practical work found that many soil evidence of crime scene. Analysis of the crime scene soil test, you can find the first crime scene, to determine the activities of the crime scene and provide more clues to detect and solve the case.
