title: Cartridge discharge residue contamination--the search for the source.
abstract: The detection of cartridge discharge residue (CDR) particles on some control samples in a firearms case started an extensive search to discover their origin. Investigation of potential sources of the contamination showed that it was airborne but random in nature, and it is recommended that frequent examination of air control samples should be made in contamination-sensitive areas.
