Source Identification and Characterization of Indoor Particulate Matter in Potala Palace Museum

Abstract

This study aims to determine the sources of indoor particulate matter at the Potala Palace Museum in Tibet, China and evaluate the potential hazards of these pollutants on cultural relics. Long-term monitoring of indoor and outdoor suspended particulate matter concentrations was conducted, and sediment particle samples were collected. The chemical composition of the deposited particles was determined using X-ray fluorescence analysis (XRF). The results showed that the outdoor suspended particulate matter concentration was much lower than that indoors, and the PM1-10 was less affected by outdoor sources, with concentrations much higher than those outdoors. The sources of indoor deposited particles in the high plateau museum can be classified into four categories: soil dust brought in by tourists from the outdoors, incense ash, pollution from human activities, and ores. Based on data analysis and discussion, installing air conditioning systems can dilute indoor suspended particulate matter through ventilation and regulate the museum's temperature and humidity to promote particle deposition.
