Annotation

THIS IS THE SECOND PAPER IN A SERIES DESCRIBING THE TECHNIQUE, PRESENTING RESULTS OF A NUMBER OF ANALYSES OF SAMPLES OBTAINED FOR A VARIETY OF HANDGUNS AND CARTRIDGES AND COLLECTED UNDER VARIOUS CONDITIONS.

Abstract

A PRIMARY OBJECTIVE OF THIS SECOND STUDY WAS 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 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 FORM HANDS. IT WAS FOUND TO BE SUPERIOR TO THE WASH PROCEDURE USED IN A PREVIOUSLY REPORTED WORK.(AUTHOR ABSTRACT MODIFIED)..TWH
