| description | <p dir="ltr">The airborne <u>microbiome</u> significantly influences human health and <u>atmospheric processes</u> within Earth's troposphere and is a crucial focus for scientific research. This study aimed to analyze the composition, diversity, distribution, and spatiotemporal characteristics of airborne microbes in Qatar's ambient air. Air samples were collected using a sampler from ten geographically or functionally distinct locations during a period of one year. Spatial and seasonal variations significantly impacted microbial concentrations, with the highest average concentrations observed at 514 ± 77 CFU/m<sup>3</sup> for bacteria over the dry-hot summer season and 134 ± 31 CFU/m<sup>3</sup> for fungi over the mild winter season. Bacterial concentrations were notably high in 80% of the locations during the dry-hot summer sampling period, while fungal concentrations peaked in 70% of the locations during winter. The microbial diversity analysis revealed several health-significant bacteria including the genera <u>Chryseobacterium, Pseudomonas, Pantoea, </u><i><u>Proteus, Myroides,</u></i><u> Yersinia, Pasteurella, Ochrobactrum, Vibrio</u>, and fungal strains relating to the genera <u>Aspergillus, Rhizopus Fusarium, </u>and<u> Penicillium</u>. Detailed biochemical and microscopic analyses were employed to identify culturable species. The strongest <u>antibiotic resistance</u> (ABR) was observed during the humid-hot summer season, with widespread resistance to <u>Metronidazole</u>. Health risk assessments based on these findings indicated potential risks associated with exposure to high concentrations of specific <u>bioaerosols</u>. This study provides essential baseline data on the natural background concentrations of <u>bioaerosols</u> in Qatar, offering insights for <u>air quality</u> assessments and forming a basis for <u>public health policy</u> recommendations, particularly in arid regions.</p><h2>Other Information</h2><p dir="ltr">Published in: Environmental Research<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.envres.2024.119879" target="_blank">https://dx.doi.org/10.1016/j.envres.2024.119879</a></p> |
