Is it true that restoring old books poses specific chemical and biological risks?

Yes. Restoring and handling old books and documents exposes workers to chemical and biological hazards, including toxic mold, bacteria, and volatile organic compounds.

Verdict: SUPPORTED · 4 sources for, 0 against · Last checked 4 Aug 2026

The analysis

The retrieved papers provide robust, multi-disciplinary evidence documenting both the biological risks (mold, bacteria, mycotoxins) and chemical risks (volatile organic compounds, residues from treatments) associated with archival materials and book restoration, thereby supporting the claim.
