Study Reveals Ancient Books May Harbor Toxic Dyes: A Call for Safe Handling Practices

A recent study from Lipscomb University warns that ancient books may contain toxic dyes, posing health risks to library visitors. With findings of heavy metals like lead and chromium, the university is taking steps to ensure safe handling while raising awareness globally.


A recent study from Lipscomb University has raised alarming concerns regarding the safety of ancient books found in libraries worldwide. These antique books, particularly those with brightly colored cloth covers, may harbor toxic dyes that pose serious health risks to library visitors. The research, which utilized advanced spectroscopic techniques, revealed that a significant percentage of these books are unsafe to handle in their current condition, primarily due to the presence of harmful pigments such as copper acetoarsenate, historically used for its vibrant emerald green color in the Victorian era.

The investigation was initiated after librarians at Lipscomb University expressed concerns about the potential dangers of the dyes used in book covers. As a result, a comprehensive project was launched to evaluate the toxicity of these books under the guidance of Assistant Professor Joseph Weinstein Webb. The research team employed three primary spectroscopic methods—X-ray analysis, inductively coupled plasma optical emission spectroscopy, and X-ray diffraction—to assess the presence of heavy metals and toxic dye molecules.

Preliminary findings indicated the presence of lead and chromium in several books, with lead concentrations exceeding acceptable limits for chronic exposure as defined by the Centers for Disease Control and Prevention. In some instances, lead levels were found to be more than double the permissible limit, while chromium levels were six times higher. In response to these critical findings, Lipscomb University has taken immediate action by wrapping potentially hazardous books in plastic to ensure safe handling and storage, while also removing those confirmed to contain dangerous dyes from public access.

The research team is committed to raising awareness about these risks, aiming to inform librarians and users globally through various publication platforms. This initiative highlights the importance of preserving historical literature while ensuring the safety of those who interact with these artifacts.

  • The study's findings were shared at the annual meeting of the American Chemical Society, emphasizing that the risks associated with these books extend beyond physical contact. Inhalation of the toxic dyes can also pose serious health threats. As libraries continue to house these historical collections, the need for thorough evaluation and safe handling practices becomes increasingly critical.
  • The use of toxic materials in art and literature from past eras reflects a broader issue concerning the preservation of cultural heritage. While these books are invaluable resources for research and education, the potential health risks they carry necessitate a balanced approach to their conservation and accessibility.
