Arsenic in collections of the 19th century
Graz University Library is aware of the ongoing worldwide discussions about the handling and use of books containing arsenic. In this context, it must be noted that only about 10% of the books tested appear to contain arsenic (usually on cloth bindings/papers in various shades of green, for more information: https://sites.udel.edu/poisonbookproject/). Arsenic becomes dangerous when it comes into contact with water or moisture, for example through damp/sweaty hands.
Some libraries have currently taken drastic measures by denying users access to potentially affected collections. We believe that a reasonable level of precautions is the better way to ensure that both our users and our colleagues are completely safe when handling this stock.
The University Library therefore recommends the following to its users and staff:
- Wearing nitrile gloves and a mask when handling suspicious books from the 19th century.
- After using such books, hands must be washed thoroughly with soap.
- Users should not touch their face or eat/drink without first washing their hands thoroughly, as arsenic may have gotten onto their hands through handling.
- If there are residues on the work surfaces/tables, these must be wiped off with a damp disposable cloth.
