Handswap analysis is carried out in criminal laboratories in order to illuminate the crime scenes in which firearms are used. The reliability of the results obtained from the analyzes is the subject of the chemistry department and is based on sample reliability. In this study, the hand swabs of people working in fifteen various business lines were obtained using transfer kit in order to acquire a scientific response to the issue of whether there would be shot residues in the hands of people in everyday life. Collected samples were first examined by Scanning Electron Microscopy (SEM-EDS). The elements of Sb&Ba&Pb, as well as their combinations, were investigated in the samples. After SEM-EDS analysis, all samples were analyzed using graphite furnace atomic absorption spectrometry (GFAAS) method to determine the amount of antimony element. According to the results, antimony element was detected on the surface of the caliper used in the printing house via GFAAS. Sb&Ba&Pb particles were also detected by SEM-EDS analysis in the swabs taken from the hands of the automobile battery repairman and the market cashier.

Öz

Ateşli silahların kullanıldığı polisiye olayların aydınlatılması için kriminal laboratuvarlarında el svap analizi yapılmaktadır. Analizlerden elde edilen sonuçların güvenilirliği, kimya anabilim dalının konusu olup örneklem güvenilirliğine dayalıdır. Bu çalışmada, insanların günlük hayatta ellerinde kurşun kalıntısı olup olmayacağı konusuna bilimsel bir cevap verebilmek için on beş farklı iş kolunda çalışan kişilerin el sürüntüleri transfer kiti kullanılarak elde edilmiştir. Toplanan numuneler ilk olarak Taramalı Elektron Mikroskobu (SEM-EDS) ile incelenmiştir. Numunelerde Sb&Ba&Pb elementleri ve bunların kombinasyonları incelenmiştir. SEM-EDS analizinden sonra tüm numuneler GFAAS yöntemi kullanılarak antimon element miktarının belirlenmesi için analiz edilmiştir. Elde edilen sonuçlara göre matbaada kullanılan kumpasın yüzeyinde GFAAS aracılığıyla antimon elementi tespit edildi. Otomobil akü tamircisi ve market kasiyerinin ellerinden alınan sürüntülerde ayrıca SEM-EDS analizi ile Sb&Ba&Pb partikülü tespit edildi.
