Three Poisonous Books Discovered in the University of Southern Denmark’s Library Collection

From an Article on The Conversation by a Research Librarian and an Associate Professor in Physics, Chemistry and Pharmacy at the University of Southern Denmark:

We found that three rare books on various historical topics in the University of Southern Denmark’s library collection contain large concentrations of arsenic on their covers. The books come from the 16th and 17th centuries.

The poisonous qualities of these books were detected by conducting a series of X-ray fluorescence analyses (micro-XRF). This technology displays the chemical spectrum of a material by analysing the characteristic “secondary” radiation that is emitted from the material during a high-energy X-ray bombardment. Micro-XRF technology is widely used within the fields of archaeology and art, when investigating the chemical elements of pottery and paintings, for example.

Now, the library stores our three poisonous volumes in separate cardboard boxes with safety labels in a ventilated cabinet. We also plan on digitising them to minimise physical handling
