(Book & Paper + Research & Technical Studies) - Contacts that leave traces: investigations into the contamination of paper surfaces from handling

The contamination of paper surfaces during the process of handling documents is a significant issue for forensic scientists and conservators. In the forensic context, it has been found that polyvinyl chloride and latex gloves would leave handprints on porous and non-porous surfaces after 20-40 minutes of wear by a subject.[1] Anecdotally, it has been seen by both forensic practitioners and by fingerprint researchers at Curtin University that nitrile gloves can also leave fingermarks on paper after periods of wear. The issue of whether to wear gloves or not to wear gloves when handling documents has also been a matter of controversy in the conservation and archivist community.[2] Prue McKay at the National Archives of Australia carried out some preliminary studies to determine the potential for contamination from gloved and non-gloved hands when handling paper items.[3] However other than the papers mentioned above there is a paucity of published research in this area. A research project has been initiated at Curtin to explore this issue by using a range of forensic fingerprint techniques to investigate the level of fingermark contamination on paper items handled with bare and covered hands. Subsequently, the effect of latent fingermarks on paper items will be investigated using artificial aging. This presentation will give an overview of the background of the methods to be used as well as presenting some of our initial results.
