A preliminary study sought to determine whether particles generated from the combustion of fireworks had any resemblance to actual particles from gunshot residue.
Abstract
The research was prompted by recognition that the fireworks industry uses compounds of lead, barium, and antimony in the manufacture of a variety of pyrotechnic devices. Some devices contain all three elements. Thus, the possibility exists that some of these devices produce particulars with some similarity to gunshot residue. The research used residues from combusted fireworks available only to licensed professionals, as well as the uncombusted composition and combusted residues from consumer fireworks. The samples were analyzed using scanning electron microscopy/energy-dispersive x-ray techniques. Results revealed that some fireworks generate particles similar to gunshot residue. Such particles were found both on the hands of professional fireworks technicians and in the combustion plume of consumer fireworks devices. Further research is needed to determine the impact that such fireworks might have on the analysis and interpretation of gunshot residue. Figures, tables, and 12 references (Author abstract modified)
