“…As such, an European project involving many forensic institutes aimed to examine the prevalence of IGSR in different groups of interest, namely the general population, car mechanics, arresting police officers and firearm owners. This study was conducted between 2017 and 2018 and was published in 2019 [ 35 ]. Statistical processing of the data was then carried out.…”

“…In a Polish study, only one characteristic particle was found on the hands of one person out of 100 persons declaring no contact with firearms (Brozek-Mucha, 2014). A recent international study investigated the prevalence on the hands of more than 1300 persons and found that the mean probability of finding at least one PbBaSb particle for a low-risk population (i.e., general population and car mechanics, n = 752 persons) was 1.7% (Stamouli et al, 2021). More than 10 PbBaSb particles were detected only on the hand of one person in the general population.…”

“…Indeed, police officers proceeding to a complicated arrest may be contaminated for example through shooting training sessions or regular contact with contaminated surfaces (e.g., police vehicles, special unit equipment, and firearms; Berk et al, 2007; Cook, 2016; Gassner & Weyermann, 2020; Gerard et al, 2013; Gialamas et al, 1995). Background samples taken at the scene and from similar materials to those under investigation are, therefore, very important to account for the risk of secondary transfer in the investigation of firearm incidents (Feeney et al, 2021; Lucas et al, 2019; Manganelli et al, 2019; Stamouli et al, 2021). For example, in Box 2, it would have been important to collect background samples from the scene of the shooting (e.g., very close to the bodies, and also further away to evaluate the “overall levels of gunshot residues in the immediate environment” as well as on the people having handled the bodies and in the vehicles used to transport them).…”

Gunshot residues (GSR) are routinely exploited by forensic scientists in the investigation of firearm-related events. While many new techniques are daily reported in the literature for the analysis of GSR, there is still a significant lack of data on the transfer, persistence, and prevalence of GSR. Such fundamental knowledge is essential to fully exploit the information potential of GSR for investigation or in Court. This article provides an overview of the relevant questions related to GSR, more particularly to infer about the trace's origin (i.e., is it from a firearm discharge?) and the activity that caused transfer (e.g., primary, secondary, or subsequent transfer). GSR production and composition will be briefly described, considering both inorganic and organic components. Then, the available knowledge about the primary transfer, the secondary transfer, and the persistence of GSR will be outlined, as well as the prevalence (background level) of the targeted elements and/or compounds in the environment, more particularly on the hands of people unrelated to firearm incidents. Finally, the methods developed for the collection, analysis, and interpretation of GSR will be discussed. A holistic approach combining fundamental forensic science knowledge about GSR transfer, persistence, and prevalence together with other available information is discussed as a path forward to increase the relevance and value of the GSR trace in practice.

“…Although these particles are found in GSR, people hands may be contaminated by Sb, Ba and Pb, depending on the working environment in different business lines (Costa et al, 2016). As a result, these three elements, particularly Sb, were given considerable attention in the study of criminal (Di Maio, 1999;Yüksel et al, 2016;Stamouli et al, 2021;Tahirukaj et al, 2021). It is known that Sb is used in some Pb alloys, as well as Sb, Ba and Pb components in the hands of people working in certain professions such as electrical installers and car mechanics (Romolo and Margot, 2001;Romolo et al, 2019) .…”

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.
