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.
