Study of possible contamination of police officers and service vehicles with gunshot residues

Abstracts

EN

The hereby article presents the analysis of data from literature of the subject, as well as of analyses of material recovered onto microscope stubs from hands of 59 police officers and traces collected from 38 police cars backseats onto ELEVAK instrument cartridges. The stubs were checked for presence of GSR particles and the filters of ELEVAK cartridges – for O-GSR and other substances. Traces were recovered at seven district police stations within Warsaw Municipal area. The analyses were performed with two analytical techniques: SEM/EDX and GC/MS. From 1 to 27 characteristic GSR particles were found on hands of 18% officers. Between 1 and 11 of such particles were detected on the surfaces of 24% car backseats. Traces of diphenylamine, a chemical substance used as a stabiliser in smokeless powders were detected in 13 vehicles, cocaine traces were found in 3 vehicles and THC was found in one vehicle.

W artykule przedstawiono analizę danych literaturowych oraz wyniki badań mikrośladów zabezpieczonych na stoliki mikroskopowe z dłoni 59 policjantów, a także mikrośladów pobranych z 38 kanap radiowozów na ładunki ELAVAK. Stoliki przebadano pod kątem obecności cząstek GSR, natomiast filtry ładunków analizowano pod kątem obecności O-GSR oraz innych substancji chemicznych. Mikroślady zabezpieczono w siedmiu rejonowych komendach Policji garnizonu stołecznego. Badania przeprowadzono dwoma technikami analitycznymi: SEM/EDX i GC/MS. Na dłoniach 18% funkcjonariuszy stwierdzono charakterystyczne cząstki GSR w liczbie od 1 do 27 sztuk, a na powierzchniach 24% kanap ujawniono od 1 do 11 takich cząstek. W przypadku 13 pojazdów na kanapach ujawniono ślady difenyloaminy – substancji chemicznej wykorzystywanej jako stabilizator w prochach bezdymnych, w trzech ślady kokainy, a w jednym THC.
