Introduction
Cultural Heritage sites such as museums, historical buildings, and monuments are vital to preserving the tangible expressions of human history and culture.These sites attract millions of visitors annually, contributing significantly to education, tourism, and local economies.They are not just spaces that house historical artifacts; they are also venues where cultural narratives are interpreted and understood.The conservation of these sites is a complex task that involves maintaining their architectural integrity, protecting their artifacts, and providing a safe environment for visitors.
The COVID-19 pandemic highlighted the vulnerabilities of indoor spaces in transmitting infectious diseases [1,2].Cultural Heritage sites, with their enclosed environments and high foot traffic, faced unique challenges [3].The pandemic necessitated a reevaluation of health safety measures and operational protocols to mitigate the spread of the virus among visitors and staff [4][5][6].Researchers have identified indoor air quality as a critical factor in the transmission dynamics of SARS-CoV-2, the virus responsible for COVID-19.Studies have shown that poor ventilation can significantly increase the risk of airborne transmission, especially in densely populated indoor settings [1,2,7,8], with respiratory conditions and allergic reactions being particularly relevant in the context of COVID-19.This concern is amplified in historical buildings that function as both workplaces and major tourist attractions, drawing crowds who may be unaware of the potential risks of airborne disease transmission in addition to the existing biological and biochemical hazards.The goal is to effectively mitigate these health risks, including those posed by pandemic, while preserving the historical and cultural integrity of these sites [9].
Protecting the health of individuals who frequent or work in these historical settings has become even more imperative in the face of the pandemic [10].This includes a diverse group of individuals such as museum curators, conservation experts, researchers, and administrative staff, who face continuous exposure not only to traditional indoor environmental pollution risks but now also to the added threat of new airborne viruses [11].The prolonged exposure to biological agents and biochemical pollutants, compounded by the risk of airborne viral transmission, underscores the need for comprehensive health protection strategies [1,2,6,12,13].
In response to these challenges, Artificial Intelligence (AI) has emerged as a potent tool for enhancing public health measures in these culturally significant spaces.AI's application spans several dimensions, from predictive modeling and visitor behavior analysis to environmental monitoring and automated management systems.By leveraging AI, site managers can not only track and predict potential health risks but also implement more effective disease prevention strategies [4, 5,12,14].For instance, AI-driven models have been used to simulate the spread of airborne pathogens in enclosed spaces, providing valuable insights that inform ventilation improvements and crowd management.
Furthermore, AI technologies such as machine learning algorithms [15] and IoT-based sensors [16] can be integrated to monitor air quality in real-time, detect the presence of pathogens, and even control visitor flows based on real-time data.This approach not only enhances the responsiveness of health safety protocols but also ensures that these measures are based on accurate and timely information, thereby minimizing disruptions while maintaining public safety.
The integration of AI into the management of Cultural Heritage sites has led to innovative applications that address both health safety and operational efficiency.For example, smart HVAC systems [17][18][19][20] equipped with AI can optimize air filtration and circulation, reducing the risk of airborne diseases.Additionally, AI-enabled surveillance systems can analyze visitor density in real time, triggering alerts when social distancing thresholds are breached, and guiding the deployment of staff to manage crowds effectively.In the battle against airborne diseases, leveraging bioremediation stands out as an innovative and strategic approach.This method utilizes both naturally occurring and engineered systems to effectively neutralize or eliminate airborne pollutants, including pathogens.By integrating bio and photochemical remediation [21][22][23] with advanced AI-driven analytics, it is possible to enhance the detection, monitoring, and management of biological contaminants.This synergy significantly mitigates the presence of hazardous chemical and biochemical agents, as well as infectious aerosols, thereby improving air quality and reducing health risks in various environments, in particular for those artifacts standing in a very delicate equilibrium [24].
AI also plays a crucial role in the post-visit analysis by providing insights through data collected on visitor movements and interactions within the site.This data is invaluable for continuous improvement of safety measures and for planning future exhibits and events to ensure they meet health guidelines without compromising the visitor experience.
