Analysis of airborne fungal spore content in different indoor microenvironments in the Cathedral of Jaén (South Spain)

Key Points

• Airborne fungal spore content varied significantly across different indoor microenvironments, indicating specific ecological niches.
• The highest spore concentrations observed reached up to 300 spores per cubic meter, emphasizing variability in indoor air quality.
• Environmental sampling employed standardized methods to analyze spore content in multiple areas of the Cathedral over a month-long period.
• Findings highlight the need for improved indoor air quality management strategies to mitigate potential health impacts, particularly in religious and public spaces.
