Sex Differentiation from Human Scent Chemical Analysis
Original language description
Human scent traces are often the only pieces of evidence providing information aboutindividuals that were present at a crime scene. In this study, the possibility of sex differentiation usingdetailed chemical analyses of human scent samples for forensic purposes is discussed. The humanscent samples were analyzed through the use of headspace-gas chromatography/mass spectrometry(HS-GC/MS). The results of these chemical analyses were evaluated using several data processingapproaches (Linear Support Vector Machine, Quadratic Discriminant Analysis, and Ridge Regression),which were applied to distinguish between sexes from the human scent samples obtained from thepalms of six volunteers for twelve weeks. This study indicates that sex differentiation based onthe chemical analysis of human scent samples using HS-GC/MS is possible. The best results wereobtained using the Ridge Regression with thresholding providing accuracy and a critical sensitivityof the sex differentiation of better than 91%.
