“…In this scenario, spectroscopic techniques, such as inductively coupled plasma optical emission spectrometry (ICP‐OES) or inductively coupled plasma coupled to mass spectrometry (ICP‐MS), appear to be valid alternatives due to their wide availability in most analytical laboratories , rapid response, and lower cost per analysis. Although they do not provide morphological information and only bulk analyses are possible, these techniques are accepted by ASTM for the analysis of IGSR . The suitability of these methods in the search for IGSR on different types of substrates has been demonstrated in the literature ; this work supports their use as a tool for the detection of IGSR and to estimate the distance from which the weapon was discharged.…”

This study concentrates on samples of bare pork skin, with and without bristles, and dried bovine ribs shot with a semi-automatic pistol to find the best methodology and sampling surface in the search for inorganic gunshot residues (IGSR). Four quadrants of known surface areas were sampled at different distances from the bullet's hole with different swabs: tapes in graphite, Leukosilk® white tape, 3M® transparent tape, and a cotton swab to assess the technique able to collect the highest amounts of IGSR with the lowest contribution of the blank. The cotton swab wet in 10% HNO gave the best results. The highest amounts of IGSR, measured by ICP-OES and MS, were detected on a surface of 3-cm radius from the bullet's edge. The amount of metals collected decreased with the firing distance between 20 and 60 cm. The procedure was efficient for sampling different tissues like skin and bones.

Laburpena: Azken urteotan, su-armen erabilera nabarmen handitu da gure gizartean eta horrek tiro egin ondoren sortutako partikulen analisirako metodologia berriak garatzea ekarri du. Krimenaren gertalekuan tiro-aztarnak (gunshot residue, GSR) osatzen dituzten konposatuen detekzioak eta identifikazioak su-armen erabileraren ebidentzia fidagarria eskaintzen dute. Tiro-aztarnak erretako eta erre gabeko partikulen multzoa dira, munizioa erretzen denean sortutakoak eta su-armak berak, jaurtigaiak eta kartutxoak askatutako konposatuez osatuak. Tiro egin ostean, partikulak tiroa gertatu den tokiaren inguruan jalkitzen dira, baina, batez ere, tiratzailearen gorputzean (eskuak, sudurra eta ilea) eta arropetan. Gaur egun, GSR partikulen ohiko analisia konposatu ez-organikoen identifikazioan oinarritzen da. Konposatu organikoen azterketak (organic gunshot residues, OGSR) lagin baten froga-balioa indartu dezake. Hala ere, gutxi dira OGSRen dudarik gabeko identifikaziorako guztiz sentikorrak diren metodoak. Lan honetan, beraz, tiro-aztarnen lagin-biltzea eta analisirako teknika aipagarrienak laburbildu eta berrikusten dira.

Abstract:In the last years, the use of firearms has increased considerably in our society which has raised the development of new analytical methodologies in order to detect the particles formed during shooting. The detection and identification of compounds consistent with gunshot residues (GSR) in a crime scene provides forensic evidence of the use of firearms. These particles are a set of burned and unburned particles formed as a result of the combustion process of ammunition and contain components expelled from the firearm itself, the projectile and the cartridge case. After the discharge, particles are deposited on all surfaces in the vicinity where the shot has taken place but mainly in shooter's body (hands, nose and hair) and clothing. Currently, conventional analysis of GRS is focused on inorganic components. The study of organic components may strengthen the probative value of a sample. However, only a few studies propose analytical methods sensitive enough to identify OGSR. The cur-

“…In this context, the use of analytical techniques in forensic analysis to GSR identification is becoming increasingly important in the replacement of traditional qualitative methods as colorimetric assays [7][8][9][10][11][12]. The inductively coupled plasma-optical emission spectrometry technique (ICP OES) [13,14] becomes promising in this sense because it has good sensitivity in the analysis of metals in addition to being multielement, simple, quick, and cheap when compared with other techniques such as scanning electron microscopy with X-ray energy dispersive detector (MEV/EDX) [12,[15][16][17] and inductively coupled plasma mass spectrometry (ICP-MS) [18][19][20].…”

Lead (Pb), barium (Ba), and antimony (Sb) concentrations were monitored in flies larvae (immatureChrysomya albiceps) contaminated with gunshot residue (GSR) from .40 caliber Taurus pistols during the period of 2 to 12 days after the death of a female pig in decomposition, during the winter, under the influence of rain and high relative humidity. The samples were also analyzed by the colorimetric test using sodium rhodizonate (Feigl-Suter reaction). It was possible to detect and quantify the three metals of interest by inductively coupled plasma-optical emission spectrometry (ICP OES), where the concentrations of all three elements kept practically constant during the putrefaction stage. Minimum ([Pb] = 382.26 μg L−1; [Ba] = 140.50 μg L−1; [Sb] = 39.18 μg L−1) and maximum ([Pb] = 522.66 μg L−1; [Ba] = 190.30 μg L−1; [Sb] = 56.14 μg L−1) concentrations were found during the third and fifth days after death, respectively. ICP OES presented higher sensitivity in metals determination when compared to the conventional colorimetric test, which showed negative result for the GSR extracts obtained from the immatureChrysomya albiceps.
