Protection Résumé : After confirming the presence of arsenic and lead in selected nineteenth-century books using XRF, the UC Berkeley Library Preservation Department and the UC Berkeley Office of Environment, Health and Safety conducted an exposure test to evaluate the risk of handling books for patrons and library staff. This test was designed to replicate a patron or conservator’s exposure levels while reading or mending a book that contains arsenic and lead. It involved handling one book for an hour, wearing fitted personal protective equipment (PPE), while taking air samples near the handler’s breathing zone, and subsequent wipe samples taken from the underlying surface and gloves used to handle the book. Results were compared with the CAL/OSHA action levels, the California Department of Health standard for lead contaminated dust, and the ‘World Trade Center Indoor Environment Assessment’ guidelines. Despite being anecdotal evidence, this case study contributes to an information gap that cannot be easily filled given that individual libraries do not have the resources to undertake a large-scale analysis of nineteenth-century materials.

Risk-based Decision-making Informed by Analysis of an Early Nineteenth-century Manuscript Containing Smalt in Studies in conservation, Vol.70 N°7-8(2025; October-November) (2025-10-01)

Conservation. Protection Résumé : This paper reviews a collaborative examination and analysis of an early nineteenth-century music manuscript at the Canadian Conservation Institute. Collaboration between conservation scientists and conservators helped process scientific information, hazards, and treatment decisions to complete the arc of planning, treatment execution, and future care recommendations for the client. An unexpected result during the initial analysis of the pigments flagged the presence of arsenic on the painted and unpainted areas of the textblock. Initial hypotheses were that it could have derived from an application of pesticide on the binding or that it was part of the papermaking process. To characterize the nature of the arsenic more fully and to attempt to understand the level of risk during handling, further analysis was carried out. Through the analysis, it was determined that the source of arsenic in the manuscript is smalt – a blue glassy colourant, added to the paper during manufacture to make it appear whiter; there was no indication of an arsenical pesticide found. This case study provoked interesting discussions regarding the contextualizing of risk and analysis results when working with an unexpected finding of potential hazards, both during the execution of a conservation treatment, and in recommending care during handling and storage.

Toxic Tales: Arsenic’s Legacy in Nineteenth-century Green Book Bindings at Northwestern University Libraries in Studies in conservation, Vol.70 N°7-8(2025; October-November) (2025-10-01)

Conservation. Protection Résumé : Northwestern University Libraries (NUL), partnering with the Northwestern University – Art Institute of Chicago Center for Scientific Studies in the Arts (NU-ACCESS), identified nineteenth-century green books that were created using arsenic and other heavy metals. Various analytical techniques have revealed that arsenical pigments were used in the USA and Europe on cloth and paper book covers, page edges, and labels producing a range of green hues and tints. Previous research has shown that over time, the pigments transform into degradation products, can migrate to non-pigmented areas, and transfer to adjacent books. As a result of these findings, NUL investigated potential hazards to users and caretakers and concluded that handling these materials presented possible health risks. NUL took steps to reduce risks to patrons and library staff including staff training, removal of suspected volumes containing arsenical materials from the open stacks, updating the reader agreement, establishment of an off-site hazardous materials storage area, creation of standard operating procedures, and development of a housing and labeling system. By sharing these activities, Northwestern hopes to build awareness of potential hazards in cultural institutions, provide safe access to the rare original materials, and provide a model for other organizations who may hold similar materials.
