A Recovery Method for Airborne Gunshot Residue Retained in Human Nasal Mucus
Each living person is equipped with their own personal particle filter, a nose. The human nose is capable of filtering and trapping airborne gunshot residue (AGSR) from discharged firearms. An extraction/concentration technique has been developed to recover the AGSR retained in human nasal mucus. The technique has successfully recovered abundant AGSR from 48 hours post-firing sample collection times. The AGSR particles were characterized by a JEOL™ 6400 scanning electron microscope coupled with a Noran™ Voyager energy dispersive X-ray spectrometer.
