Special Issue Information
Dear Colleagues,
Bioaerosols—biological particles suspended in the air—are central to various scientific fields, ranging from environmental science to public health and climate studies. Composed of microorganisms (bacteria, viruses, and fungi), fragments of biological material, and biogenic volatile compounds, bioaerosols influence numerous natural and human-made systems. Their emission, transportation, and fate have wide-reaching implications, from indoor air quality and disease transmission to ecological dynamics and atmospheric processes.
Despite significant advances, our understanding of the mechanisms underlying bioaerosol formation, release, and dispersion remains incomplete. Furthermore, new analytical techniques and innovations in computational modeling are unlocking previously hidden insights into their structure and behavior. This Special Issue seeks to highlight cutting-edge research that elucidates the emission pathways, complex characterization, interactions with particulate matter and mechanistic understanding of bioaerosols across various scales and environments.
Contributions featured in this issue explore the intersection of public health, ecology, chemistry, physics, and engineering. They examine topics such as the quantification of bioaerosol sources, the influence of environmental and anthropogenic factors on emission rates, and the molecular-level interactions driving bioaerosol aggregation and transport. This body of work also aims to advance methodologies for bioaerosol sampling and characterization, real-time monitoring, and high-resolution characterization through state-of-the-art tools such as next-generation sequencing, spectroscopy, mass spectrometry and bioinformatics.
Through these multidisciplinary perspectives, we aim to foster a deeper, systems-level understanding of bioaerosol dynamics. By addressing current knowledge gaps, this collection of studies can support the development of mitigation strategies for bioaerosol-related health risks, as well as inform policy and industrial practices across sectors like agriculture, healthcare, and environmental protection.
We are excited to present this Special Issue on "Bioaerosols: Emission, Characterisation, and Mechanisms", which brings together novel insights and emerging themes that will shape future research and applications. We invite readers to engage with the breadth and depth of work presented and contribute to this rapidly evolving field.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Atmosphere is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
