Screening of gunshot residues using desorption electrospray ionisation-mass spectrometry (DESI-MS) [PDF]
, 2012 Several studies have indicated that there are potential environmental sources of particles resembling inorganic primer found in gunshot residues (GSR); as a consequence examiners are reluctant to unambiguously assign the origin of inorganic particles. If

Time since discharge of 9mm cartridges by headspace analysis, part 1: Comprehensive optimisation and validation of a headspace sorptive extraction (HSSE) method. [PDF]
, 2017 Estimating the time since discharge of spent cartridges can be a valuable tool in the forensic investigation of firearm-related crimes. To reach this aim, it was previously proposed that the decrease of volatile organic compounds released during ...

The relationship between gunshot-residue particle size and Boltzmann distribution
Forensic Sciences Research, 2020 Gunshot-residue (GSR) particles usually form spherical structures, have special dimensions, and a composition that consists of burned and partially unburned matter with a 0.5–50-µm diameter (sometimes larger).

An Examination of Gunshot Residue and Lead Exposure
Proceedings of the West Virginia Academy of Science, 2023 This study examines the longevity of gunshot residue (GSR) for lead-based and lead-free ammunition and verifies that lead-free ammunition is truly lead-free. While a GSR presumptive test is not a definitive answer to whether GSR is explicitly present, it

Scanning electron microscopy and energy-dispersive x-ray spectroscopy (SEM-EDX) confirms shooting of a hen harrier (Circus cyaneus) [PDF]
, 2015 The hen harrier (Circus cyaneus) remains severely restricted as a breeding species in England despite sufficient habitat for over 300 breeding pairs. Human persecution is the main limiting factor and in the UK, there have been 45 confirmed incidents of ...
