Abstract

The purpose of this research was to study elements in soil samples and compare the characteristics of soil sources and samples by investigating five groups of soil series in Surin Province: No. 17 (Salakdai Sub-District), No. 33 (Sawai Sub-District), No. 22 (Piaram Sub-District), No. 38 (Kho Kho Sub-District), and No. 40 (Ta-Ong Sub-District). The soil samples from these groups of soil series were analyzed using the Energy Dispersive X-Ray Fluorescence technique. The analysis revealed the presence of nine soil elements, including silicon (Si), iron (Fe), titanium (Ti), and zirconium (Zr), in all the groups. To compare the results of each element's content in the soil samples, Duncan's New Multiple Range Test (DMRT) method was utilized at a 95 percent confidence level. The content of elements in each soil sample was found to be significantly different. Next, the content of trace elements identified in the different groups of soil series was compared to the groups of soil series sampled from shoes using the T-Test method. The study results indicated that there was no statistically significant difference between the average elemental content of each group of soil series and the soil series collected from the shoes. Therefore, this analysis method may be used in combination with related evidence to link suspects to specific locations.
