    Abstract

    This is the second paper in a series describing the photoluminescence technique for detection of gunshot residue. It presents results of a substantial number of analyses of samples obtained for a variety of handguns and cartridges and collected under various conditions. A primary objective of the second study has been to evaluate factors which affect the utility of the method, such as the persistence of residue on the hand after firing, the effect of activity on retention of residue, and the possible presence of identifiable residue on surfaces other than the hand. The data represent an extensive addition to existing information on lead in gunshot residue and samples from several environmental conditions. A new method of residue collection, based on an adhesive layer, was used to collect samples from hands. It was found to be superior to the wash procedure used in the previously reported work [1]. For background information on the luminescence method the reader is referred to the earlier report.
