“…The airflow in crowed archeological sites contains a high amount of fungal spores including the Aspergillus genus, Malassezia [ 109 , 112 ], and these genera are often the dominant genera on the surface of the murals and can lead to biodeterioration of the murals [ 109 , 113 ]. Without adequate protection measures, airborne fungi are an important source of contamination on the murals, and some murals can be seriously contaminated and even damaged after a large number of visitors come [ 114 ]. Inappropriate restoration interventions can directly remove the materials from the murals and may result in secondary damage to the murals [ 115 , 116 ].…”

“…However, visitor walking can increase the bioaerosols particles. Although the installation of glass barriers near the wall can decrease the deposition number of bioaerosols particles and thus can protect murals from the deposition of bioaerosols particles, visitors can still change the moisture and air flow, thus leading to further deterioration of murals [ 114 ]. It has been well recognized that it is important to preserve the cultural landscape of mural destinations, and strict measures should be performed.…”

As non-renewable cultural heritages, murals have important implications in historical customs, religions, and philosophy as well as their aesthetic values. Recently, many murals are threatened by natural factors and human activities. During the past decades, there are increasing interest in the investigation of murals. Here we review the current status of murals and provide an up-to-date summary of achievements related to murals. The murals that draw the most attention are distributed in Mexico, Ireland, China, and Spain. The aesthetics, history, cultural, educational, and economic values of murals are comprehensively analyzed. The main research technologies used to detect the chemical compositions and physical structures of murals are also summarized. The restoration of murals includes several procedures such as stabilization, repair, surface cleaning, and pigment reconversion. Emerging technologies such as computer science benefit the research and conservation of murals. We also propose that tourism management and climate change should be incorporated into the conservation of murals in the future.

“…Various research fndings, conclusions, and recommendations regarding the enhancement of air quality in diferent areas have provided outstanding contributions. By reviewing and summarizing the research methods used by international and professional scholars investigating topics related to air quality, we found that international methods for examining IAQ typically involve the following procedures: an exploration and review of previous research, relevant data analysis, experimental collection of air bioaerosol samples, selection of suitable mediums for sample cultivation, and fnally, use of microscopes for determining the number of bioaerosols in the culture medium, which is then used to calculate the concentration of bioaerosols in 1 m 3 of air [12,[22][23][24][25][26][27][28][29][30][31][32][33][34][35].…”

Key Elements Affecting the Library’s CFU Concentration in Taiwan

et al. 2023

Public libraries are popular gathering places, so understanding the factors that contribute to colony-forming unit (CFU) concentrations and how to minimize them is essential. This study aimed to investigate the factors that affect CFU concentrations in a public library, using air sampling (Bioluminescent ATP-assay) and statistical analysis software (SPSS) to collect and analyze data. The findings indicated that the CFU concentration in the library was significantly influenced by the air quality surrounding the building, the number of library visitors, and the hygiene and health of both visitors and employees. Additionally, indoor temperature and humidity were found to be key factors affecting CFU concentration. These findings suggest the need for better ventilation and air filtration systems, as well as regular cleaning and disinfection in public libraries. Furthermore, research is recommended to investigate other potential factors that may impact indoor air quality in public spaces.
