Conservation. Protection Résumé : Public perception of arsenic in nineteenth-century Britain encompassed a variety of things: criminal poison, useful medicine, and a raw material for manufacturing an array of goods. During this era, Henry Carr tested wallpaper and fabric samples sent in by private individuals and manufacturers, as part of an early effort in gathering scientific data to inform and protect consumers against chronic arsenic poisoning. In 2022, eight wallpaper samples that Carr had tested were acquired by Winterthur Library. These samples were analyzed by polarized light microscopy, scanning electron microscopy with energy dispersive X-ray spectroscopy, X-ray fluorescence, and Raman spectroscopy to identify the presence of arsenic. Of the eight wallpaper swatches, seven suggested trace-to-elevated levels of both arsenic and copper. Two swatches were confirmed as having the arsenical pigment emerald green (copper acetoarsenite) specifically. Research into these wallpaper samples furthers the legacy of knowledge gathering and sharing in order to protect everyday users by contributing to toxicology research in library and archives materials.

Multi-Analytical Investigation of Arsenical Transfer and Remediation on Nineteenth-Century Green Books in Studies in conservation, Vol.70 N°7-8(2025; October-November) (2025-10-01)

Conservation. Protection Résumé : Books containing heavy metals, specifically nineteenth-century green arsenical books, have been identified at Northwestern University Libraries, raising health and safety concerns related to handling. Copper acetoarsenite pigments, such as emerald green, were detected on book covers, decorative page edges, labels, and other components using noninvasive analytical techniques including X-ray fluorescence (XRF), Raman spectroscopy, and Fourier-transform infrared (FTIR) spectroscopy. Further examination of selected volumes using synchrotron radiation (SR) techniques revealed pigment migration, degradation, and arsenic transfer to adjacent books. This paper expands on initial findings through two related experiments. The first explored the transfer of arsenic using mechanical friction; Staedtler Mars® white vinyl erasers rubbed on arsenical books generated crumbs which were analyzed via scanning electron microscopy–energy-dispersive X-ray spectroscopy (SEM-EDX). Results confirmed the transfer of arsenic, copper, and lead, with decorative page edges being particularly prone to shedding arsenic onto other materials. The second experiment tested remediation methods on a book contaminated by prolonged exposure to an arsenical neighbor. Surface cleaning using erasers and a vacuum removed flecks of pigment but did not eliminate non-chromophoric arsenic as confirmed by SR analyses, which highlights its presence either as a degradation product embedded within the paper or present in the paper as part of its production process. Findings demonstrate the acute toxicity risk posed by arsenical books and support the need for safe handling protocols. However, materials with only trace levels of arsenic embedded during production may pose a lower risk of transfer. Cross contamination beyond prolonged direct contact appears limited. These results highlight critical considerations for library preservation practices and future research on arsenic in historical materials.

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.
