Abstract

For public-use facilities in urban centers with high occupancy, it is imperative to effectively manage opportunistic pathogenic bacteria due to the diverse range of users, including the immunocompromised population, such as the elderly, children. Therefore, we investigated the concentration of airborne bacteria at several public-use facilities in urban centers in South Korea. The level of total airborne bacteria in the facilities was positively correlated with user density and CO2 levels. Notably, subway compartments demonstrated particularly high levels of airborne bacteria. Subway compartments and daycare centers contained opportunistic pathogenic bacteria associated with antibiotic resistance. The relative abundance of genera associated with these species showed minor differences by season and facility; the genera Klebsiella and Staphylococcus showed high relative abundance in subway compartments and daycare centers, respectively. Based on our findings, we recommend enhancing management strategies targeting opportunistic pathogenic bacteria related to antibiotic resistance in the air of subway compartments and daycare centers.

以影响因素和机会致病菌为重点,评估公共设施室内空气中的细菌
对于入住率较高的城市中心公共设施而言,由于使用者的多样性,包括老人、儿童等免疫力低下的人群,有效管理机会性致病菌势在必行。因此,我们对韩国城市中心几处公共设施的空气细菌浓度进行了调查。这些设施中的空气细菌总数与使用者密度和二氧化碳水平呈正相关。值得注意的是,地铁车厢内的空气传播细菌含量特别高。地铁车厢和日托中心含有与抗生素耐药性相关的机会致病菌。与这些物种相关的菌属的相对丰度因季节和设施的不同而略有差异;克雷伯氏菌属和葡萄球菌属分别在地铁车厢和日托中心显示出较高的相对丰度。根据我们的研究结果,我们建议针对地铁车厢和日托中心空气中与抗生素耐药性有关的机会致病菌加强管理策略。

期刊介绍: Air Quality, Atmosphere, and Health is a multidisciplinary journal which, by its very name, illustrates the broad range of work it publishes and which focuses on atmospheric consequences of human activities and their implications for human and ecological health. It offers research papers, critical literature reviews and commentaries, as well as special issues devoted to topical subjects or themes. International in scope, the journal presents papers that inform and stimulate a global readership, as the topic addressed are global in their import. Consequently, we do not encourage submission of papers involving local data that relate to local problems. Unless they demonstrate wide applicability, these are better submitted to national or regional journals. Air Quality, Atmosphere & Health addresses such topics as acid precipitation; airborne particulate matter; air quality monitoring and management; exposure assessment; risk assessment; indoor air quality; atmospheric chemistry; atmospheric modeling and prediction; air pollution climatology; climate change and air quality; air pollution measurement; atmospheric impact assessment; forest-fire emissions; atmospheric science; greenhouse gases; health and ecological effects; clean air technology; regional and global change and satellite measurements. This journal benefits a diverse audience of researchers, public health officials and policy makers addressing problems that call for solutions based in evidence from atmospheric and exposure assessment scientists, epidemiologists, and risk assessors. Publication in the journal affords the opportunity to reach beyond defined disciplinary niches to this broader readership.
