- Abstract
For forensic purposes, sometimes, it is necessary to analyze the soil few years after the initial case has been closed. Soil can leave traces on any item such as shoes, car tires, clothes etc. In this paper 60 soil samples are analyzed. 48 soil samples were taken in three locations in the city of Tetovo in 2016. Three years later (in 2019) 12 additional soil samples from the same locations were collected. All samples were dried at 110 °C, and then their infrared spectra (IR) were recorded. The infrared spectra were recorded on Fourier-transform infrared spectrophotometer Perkin-Elmer System 2000. The collected IR spectra we analyzed carefully analyzed in the part of the fingerprint region (in the range 1450-450) in order to examine the changes in the spectra which have resulted from the changes of the weather and the anthropogenic influence. The detailed examination of all spectra showed that no visible changes were found in the newly collected spectra.
