The aim of this work was to study the diversity and spatiotemporal fluctuations of airborne fungi in the National Library of Greece after its relocation from the Vallianeio historic building in the center of Athens to entirely new premises at the Stavros Niarchos Foundation Cultural Center, and also to compare the fungal aerosol in between the two sites. The air mycobiota were studied by a volumetric culture-based method, during the year 2019 in order to assess their diversity and abundance and to compare with those previously reported in the historic building. Twenty-eight genera of filamentous fungi were recovered indoors and 17 outdoors, in addition to yeasts registered as a group. The number of fungal genera recovered was almost similar in both premises, whereas seventeen genera indoors were identical, dominated by , and . The mean daily fungal concentration was found to be 66 CFU m indoors and 927 CFU m outdoors in the new location 293 and 428 CFU m indoors and 707 and 648 CFU m outdoors in the previous one. The mean daily concentration indoors was consistently and significantly lower ( < 0.05) in the new building than in the historic one, although it was higher outdoors. The indoor/outdoor ratio for the total fungi was 0.07 in the new 0.41 and 0.66 in the previous one and reveals a superior indoor air quality in the new site. Air temperature and occupancy had a statistically significant impact on the concentration of indoor fungi. The remarkably reduced concentration of the mycobiota in the new premises indicated a considerable decline in fungal burden, mainly due to technological excellency of the facility and continuous preventive measures to ensure an enhanced indoor air quality in the National Library of Greece. This case study provides a paradigm about upgrading of indoor air after re-establishment of a facility in another setting.
这项工作的目的是研究希腊国家图书馆从雅典市中心的瓦利亚内奥历史建筑迁至斯塔夫罗斯·尼亚尔霍斯基金会文化中心全新馆舍后，空气中真菌的多样性和时空波动情况，并比较这两个地点的真菌气溶胶。为了评估空气真菌群落的多样性和丰度，并与历史建筑中先前报告的情况进行比较，于2019年采用基于体积培养的方法对空气真菌群落进行了研究。室内共分离出28个丝状真菌属，室外17个，此外还有作为一组记录的酵母。在两个馆舍中回收的真菌属数量几乎相似，而室内有17个属相同，主要由 、 和 属主导。新馆舍室内真菌平均日浓度为66 CFU/m³，室外为927 CFU/m³；前一个馆舍室内为293和428 CFU/m³，室外为707和648 CFU/m³。新建筑室内平均日浓度始终显著低于历史建筑（<0.05），尽管室外浓度更高。新馆舍中总真菌的室内/室外比值为0.07，前一个馆舍为0.41和0.66，这表明新馆舍的室内空气质量更好。气温和人员占用情况对室内真菌浓度有统计学上的显著影响。新馆舍中真菌群落浓度显著降低，表明真菌负荷大幅下降，这主要归因于该设施的卓越技术以及为确保希腊国家图书馆室内空气质量得到改善而采取的持续预防措施。本案例研究为在另一环境中重新设立设施后室内空气升级提供了一个范例。
