Abstract

Bioaerosols, a significant yet underexplored component of atmospheric particulate matter, pose substantial public health risks, particularly in regions with poor air quality. This study investigates the composition of bioaerosols in public spaces, specifically two interstate motor parks and two marketplaces in Osun State, Nigeria, over six months. Air samples were collected, and bacterial and fungal species were identified, focusing on pathogenic organisms. The results revealed the presence of well-known pathogens, including Staphylococcus aureus, Escherichia coli, Klebsiella sp., Pseudomonas aeruginosa, Aspergillus sp., and Fusarium sp., which are associated with respiratory and gastrointestinal infections, as well as antimicrobial resistance. Site-specific differences in microbial diversity were observed, with higher bacterial diversity in motor parks and greater fungal occurrence in marketplaces influenced by environmental factors such as waste management. The findings highlight the urgent need for microbial air quality monitoring in public spaces, alongside improved sanitation practices. This study provides critical insights into the public health risks posed by bioaerosols and calls for local and global interventions to mitigate the impact of airborne pathogens in urban environments.

尼日利亚西南部交通繁忙的城市地区生物气溶胶组成和公共卫生影响的评估。
生物气溶胶是大气颗粒物中一个重要但尚未得到充分探索的组成部分,对公共健康构成重大风险,特别是在空气质量差的区域。本研究调查了公共空间中生物气溶胶的组成,特别是在尼日利亚奥孙州的两个州际汽车停车场和两个市场,为期六个月。收集了空气样本,鉴定了细菌和真菌种类,重点是病原生物。结果显示,存在众所周知的病原体,包括金黄色葡萄球菌、大肠杆菌、克雷伯氏菌、铜绿假单胞菌、曲霉和镰刀菌,这些病原体与呼吸道和胃肠道感染以及抗菌素耐药性有关。观察到微生物多样性的具体地点差异,汽车停车场的细菌多样性较高,而受废物管理等环境因素影响的市场的真菌发生率较高。研究结果强调了在公共场所进行微生物空气质量监测以及改善卫生习惯的迫切需要。这项研究为生物气溶胶带来的公共卫生风险提供了重要见解,并呼吁采取地方和全球干预措施,以减轻城市环境中空气传播病原体的影响。
