Abstract

The aim of this study was to identify and quantify the airborne fungal spore content in the Cathedral of Jaén (South Spain). The evaluation of the microclimatic conditions and their relationship with the presence of airborne fungal spores in different indoor areas was also tested. Airborne fungal spores were recorded during 2019 by using a volumetric sampler. The Choir was the study area with the maximum airborne fungal spore concentrations, representing 55% of the total compared to the minimum representation of 12% sampled in the Museum. Regarding the seasonality, winter records represented only 20% of the total the airborne spore monitoring. Peaks in the daily spore concentrations were mainly recorded in the first half of spring and during the middle of the summer. A total of 29 taxa were identified. Cladosporium and Aspergillus/Penicillium were the potentially biodeteriogen fungal spores that were more frequently recorded in all of the study areas. Of the total airborne fungal spores recorded in the indoor environment, 82.5% belong to biodeteriogen fungi that, under suitable conditions for their germination, could have a negative effect on the preservation of artistic-historical heritage. The installation and correct maintenance of air-conditioning systems and the aeromycological analysis in suspected places would be recommended.

Jaén大教堂（西班牙南部）不同室内微环境中空气传播真菌孢子含量的分析

本研究的目的是确定和量化Jaén大教堂（西班牙南部）空气中真菌孢子的含量。还对不同室内区域的小气候条件及其与空气传播真菌孢子存在的关系进行了评估。2019年，通过使用体积采样器记录了空气中的真菌孢子。合唱团是空气中真菌孢子浓度最高的研究区域，占总数的55%，而博物馆采样的真菌孢子浓度最低，为12%。就季节性而言，冬季记录仅占空气传播孢子监测总量的20%。孢子日浓度峰值主要出现在春季前半段和仲夏。共鉴定出29个分类群。枝孢菌和曲霉菌/青霉是潜在的生物定源真菌孢子，在所有研究领域都有更频繁的记录。在室内环境中记录的空气传播真菌孢子总数中，82.5%属于生物定源真菌，在适当的发芽条件下，这些真菌可能会对艺术历史遗产的保护产生负面影响。建议在可疑地点安装和正确维护空调系统，并进行空气真菌学分析。

期刊介绍： Associated with the International Association for Aerobiology, Aerobiologia is an international medium for original research and review articles in the interdisciplinary fields of aerobiology and interaction of human, plant and animal systems on the biosphere. Coverage includes bioaerosols, transport mechanisms, biometeorology, climatology, air-sea interaction, land-surface/atmosphere interaction, biological pollution, biological input to global change, microbiology, aeromycology, aeropalynology, arthropod dispersal and environmental policy. Emphasis is placed on respiratory allergology, plant pathology, pest management, biological weathering and biodeterioration, indoor air quality, air-conditioning technology, industrial aerobiology and more. Aerobiologia serves aerobiologists, and other professionals in medicine, public health, industrial and environmental hygiene, biological sciences, agriculture, atmospheric physics, botany, environmental science and cultural heritage.
