Article Synopsis
- The study focuses on improving gunshot residue (GSR) detection by exploring organic compounds alongside traditional inorganic particles, especially relevant when using lead-free ammunition.
- The researchers developed a method for extracting and analyzing both types of GSR from a single sample, making it feasible for existing investigative practices.
- By utilizing techniques like SPME-GC-MS and SEM-EDX, they successfully identified specific organic compounds and inorganic particles, enhancing the overall chemical profile and importance of GSR evidence for investigations.
A review of the literature concerning the fate and behavior of gunshot residue (GSR) is presented. A number of concomitant parameters including firearm and ammunition type, plume and GSR material characteristics, travel distances, chemical composition and GSR morphology are critically discussed in relation to their effects on the distribution and deposition, transfer and persistence processes of GSR. The underlying mechanisms associated with such processes are also considered.
