Forensic Soil Analysis is the use of soil sciences and other disciplines to aid in criminal investigation. Soils are like fingerprints because every type of soil that exists has unique properties that act as identification markers. This means that the origin of the soil sample can be identified. For example, clay embedded in the sneaker…
7. Density Analysis of Soil. Density (Volumetric Mass Density) denotes the ratio of the mass of a body to its volume. Inorganic particles in soil, such as minerals and rocks, and other geological materials have densities dependent on the spatial distribution of their atoms. Forensic Laboratory Techniques for Soil Density Analysis
However, despite initial studies demonstrating the potential of soil DNA analysis to assist forensic investigations, the authors emphasize that further research is required to explore the use of indicator taxa for identifying the likely origin of an unknown soil to evaluate the strength of a soil comparison using large reference databases and, ultimately, to integrate this analysis into ...
Dec 5, 2023 · Soil analysis serves various critical purposes in forensic investigations. It helps delineate the geographical extent of a crime scene, assesses the likelihood of a burial or clandestine grave, and even aids in tracking the movement of scents using human remains detection dogs. Furthermore, soil analysis can determine the soil type from an ...
The present review highlights various analytical techniques (ATR-FTIR, pyGC-MS, SEM-EDX, ICP-MS/OES and XRD) for soil analysis (colour comparison, texture and particle size determination, density gradient methods and organic matter estimation) and discusses some of the famous cases solved with soil trace evidence.
