Handling Books That May Contain Heavy Metals
Certain colorful 19th-century book covers can hide traces of heavy metals. Learn what’s at risk, and how to safely handle these historic volumes, while protecting yourself and the collection.
Some materials in the UCLA Library system’s 19th-century print collection may have book covers that contain heavy metals. Heavy metals were previously used to embellish book covers with colorful, decorative pigments; however, this practice was discontinued before the end of the 19th-century. A group of universities performed an independent study of their book collections featuring cloth and leather bindings, and found small amounts of arsenic in emerald-green books, mercury in red books, chromium in yellow books and lead in a variety of book cover colors. These heavy metals were found on a case-by-case basis for certain publications, and many 19th-century publications will not actually contain heavy metal content.
If you need to use a 19th-century book (publication date: 1800-1899) which contains its original cloth or leather cover, first ask a librarian to help you find a digitized copy. If the text has not been digitized and you want to use the hardcopy book, additional safety precautions are recommended out of an abundance of caution for library users.
Heavy metals from textiles and leather are not airborne and do not readily transmit through the skin. The potential risk primarily comes from ingestion of small pieces of pigment that may flake off the cover during handling.
If you choose to use these suspected volumes, it is best practice to observe the following precautions:
Wear nitrile gloves (available at circulation desks and in Library Special Collections).
Place the book on a hard, flat surface (such as a table). Avoid upholstered furniture.
Do not eat, smoke or touch your face. Limit contact with other surfaces (such as personal items).
Note: Gloved hands can make it more difficult to properly grip book pages. To prevent pages from tearing, turn the book pages more slowly, carefully and deliberately.
Place the book in a clear, re-sealable, storage bag (such as a Ziploc bag) at all times when not in use. Keep the book away from children and pets.
Use a damp, disposable cloth to wipe down the area where the book was placed. Also wipe down any other surfaces that were touched with gloved hands (such as personal items).
Wash your hands thoroughly with soap and water immediately after removing and disposing your gloves.
Do not place the book in the book drop. Instead, return the item to circulation staff in a clear re-sealable storage bag.
