This study attempted to evaluate the bioaerosol exposure of apartment residents at high-rise apartment buildings in a Korean city. The characteristics associated with the bioaerosol exposure included the apartment floor, seasonal variation, summer survey period (seasonal rain-front period (SRFP) or no rain-front period (NRFP)), and room location inside an apartment. Four most prevalent fungal genera detected in both the indoor and the outdoor air were Cladosporium, Penicillium, Aspergillus, and Alternaria. The outdoor bacterial concentrations were significantly higher in the low-floor apartments than in the high-floor apartments. However, the bacterial and fungal concentrations in the interior air of the apartments were not significantly different between the low- and the high-floor apartments. The current bioaerosol concentrations were comparable to those in other reports, with geometric mean (GM) bacterial values between 10 and 10(3) CFU m(-3) and fungal aerosol concentrations in homes ranging also from 10 to 10(3) CFU m(-3). The indoor and outdoor fungal concentrations and the outdoor bacterial concentrations were usually higher in the summer than in the winter. The indoor and outdoor bioaerosol concentrations were both higher for the SRFP than for the NRFP. The difference in the total bacterial concentrations was not significant among the surveyed five rooms. The GM total fungal and Cladosporium concentrations, however, were significantly higher for the kitchen than for the other rooms.
本研究旨在评估韩国某城市高层公寓楼居民的生物气溶胶暴露情况。与生物气溶胶暴露相关的特征包括公寓楼层、季节变化、夏季调查期（季节性雨锋期（SRFP）或无雨锋期（NRFP））以及公寓内房间位置。在室内和室外空气中检测到的四种最常见真菌属为枝孢属、青霉属、曲霉属和链格孢属。低层公寓的室外细菌浓度显著高于高层公寓。然而，低层和高层公寓室内空气中的细菌和真菌浓度没有显著差异。当前的生物气溶胶浓度与其他报告中的浓度相当，细菌几何平均值（GM）在10至10³ CFU m⁻³之间，家庭中的真菌气溶胶浓度也在10至10³ CFU m⁻³之间。室内和室外真菌浓度以及室外细菌浓度通常夏季高于冬季。SRFP期间的室内和室外生物气溶胶浓度均高于NRFP期间。在所调查的五个房间中，总细菌浓度差异不显著。然而，厨房中真菌和枝孢属的GM总浓度显著高于其他房间。
