Monitoring and Mitigating Particulate Matter Deposition on Decorative Surfaces: Current and Future Approaches in the Palace of Westminster

A new method for monitoring dust deposition on vertical surfaces, using imaging and open-source software (CHIJ workflow in ImageJ), was successfully trialled at the Palace of Westminster. This approach revealed significant discrepancies between data collected directly on wall paintings and traditional horizontal glass slide proxies, offering a more accurate assessment of particulate matter deposition trends. The study identified anthropogenic, geogenic, and biological sources of dust, highlighting seasonal variations and works-related impacts. Mitigation measures implemented to protect decorative surfaces demonstrated effectiveness in reducing dust diffusion. This low-tech yet robust method provides conservationists with data-driven tools for informed decision-making in heritage preservation.
