“…Future research also needs to complement metagenomically identified bacteria and fungi by monitoring culturability to better assess microorganisms’ role in ecosystem, human, plant, and animal health. ,,,,− Such studies should also measure other water-soluble aerosol components and metal speciation, some of which might affect viability. Additionally, airborne pollutants have the capacity to influence aerobiome abundance, diversity, transport, and deposition, and conversely, bioaerosols can facilitate the transport and deposition of airborne pollutants. , The interplay between bioaerosols and anthropogenic emissions is complex and dependent on multiple factors, including pollutant type, concentration levels, and meteorological parameters. Longer-term measurements, including microbial viability, can provide clues to such interactions.…”

Although airborne bacteria and fungi can impact human, animal, plant, and ecosystem health, very few studies have investigated the possible impact of their long-range transport in the context of more commonly measured aerosol species, especially those present in an urban environment. We report first-of-kind simultaneous measurements of the elemental and microbial composition of North American respirable airborne particulate matter concurrent with a Saharan−Sahelian dust episode. Comprehensive taxonomic and phylogenetic profiles of microbial communities obtained by 16S/18S/ITS rDNA sequencing identified hundreds of bacteria and fungi, including several cataloged in the World Health Organization's lists of global priority human pathogens along with numerous other animal and plant pathogens and (poly)extremophiles. While elemental analysis sensitively tracked long-range transported Saharan dust and its mixing with locally emitted aerosols, microbial diversity, phylogeny, composition, and abundance did not well correlate with the apportioned African dust mass. Bacterial/fungal diversity, phylogenetic signal, and community turnover were strongly correlated to apportioned sources (especially vehicular emissions and construction activities) and elemental composition (especially calcium). Bacterial communities were substantially more dissimilar from each other across sampling days than were fungal communities. Generalized dissimilarity modeling revealed that daily compositional turnover in both communities was linked to calcium concentrations and aerosols from local vehicles and Saharan dust. Because African dust is known to impact large areas in northern South America, the Caribbean Basin, and the southern United States, the microbiological impacts of such long-range transport should be assessed in these regions.

“…The bioaerosols, in their airborne state, engage in dynamic interactions with particulate matter, subsequently integrating into water droplets present in cloud formations, precipitation, and fog (Fröhlich-Nowoisky et al, 2016;Shammi et al, 2021;Sajjad et al, 2023). The phenomenon of advection further facilitates the extensive transportation of these bioaerosols across considerable distances, culminating in their re-deposition onto terrestrial surfaces through dry and wet deposition processes (Petroselli et al, 2021;Xie et al, 2021).…”

The outbreak of the coronavirus disease 2019 (COVID-19) pandemic has sparked significant concerns regarding the significance of bioaerosols . Assessing air quality and identifying microbial pollution is crucial for estimating health risks and establishing air quality control standards. This research aimed to comprehensively investigate the microbial composition of the air at selected sites in Nigeria, focusing on the presence of potential pathogenic organisms. Over a duration of six months, from October 2019 to March 2020, samples were collected using settle plates employing the open-plate method. Standard Petri dishes containing culture media were exposed to the air for 10 to 15 minutes, facilitating the collection of settled biological particles. The designated locations included two interstate travel motor parks and two marketplaces situated in Ede and Osogbo, Osun State, Nigeria. The isolates underwent preliminary identification tests, followed by further identification of bacterial isolates using molecular techniques were employed including DNA amplification of the 16S rDNA gene using polymerase chain reaction (PCR), agarose gel electrophoresis of PCR amplicons, Sanger sequencing of bacterial 16S rDNA gene, and subsequent phylogenetic and evolutionary analysis using MEGA X. The results revealed the presence of diverse microorganisms, including pathogenic species, highlighting the importance of monitoring air quality for public health. This study contributes to the understanding of microbial pollution in the air and provides valuable insights for air quality management strategies.
