An analytical approach for forensic comparison of soil samples of Delhi region

Soil serves as valuable trace evidence in forensic investigations due to its unique properties and transferability Soil is important trace evidence due to its unique geo-marker property and morphological structure because each type of soil has precise habitats that act as identification markers. This heterogeneity is the ability to compare and identify two different soil types. Hence, the availability of soil databases of different areas of a particular region can be of utmost importance in the crime scene investigation.

Soil samples were collected from representative locations in each region. Analysis included preliminary and confirmatory tests followed by instrumental techniques.

Compiled data created comprehensive soil profiles for each region. Comparative analysis highlighted distinct characteristics and identified geomarkers and morphological structures unique to each area.

Soil profiling of the four Delhi regions provided valuable insights for forensic investigations. Databases can be established using the discussed analytical techniques that can aid in geographical location determination and differentiation of soil samples.
