Paper
Antimicrobial activity of safe concentrations of ozone, hydrogen peroxide, and triethylene glycol in air and surfaces
The application of low and non-toxic concentrations of antimicrobial compounds in indoor air is an interesting strategy to reduce airborne bacteria and fungi thereby reducing infection risk.
Paper
Nycterohemeral airborne fungal and bacterial communities and health risks of potential pathogens in Shanghai
Urbanization-influenced airborne microorganisms and megacity bioaerosols have garnered particular attention due to their importance in the atmospheric environment.
Paper
Size dependent effectiveness of engineering and administrative control strategies for both short- and long-range airborne transmission control
Using a size-dependent transmission model linking short- and long-range airborne transmission, we re-estimate the effectiveness of control strategies in mitigating airborne transmission, while concurrently underscoring the need to consider droplet size in airborne transmission dynamics.
Paper
Negligible increase in indoor endotoxin activity by 222 nm far-UVC illumination on bioaerosols
Far-UVC irradiation (222 nm) is an emerging approach for disinfection due to its effectiveness and potentially harmless nature to humans by direct irradiation compared with other UV wavelengths.
Paper
Resolving the controls over the production and emission of ice-nucleating particles in sea spray
Oceans emit ice-nucleating particles (INPs) which freeze supercooled cloud droplets, modifying clouds. We added dead biomass of three phytoplankton to seawater. Each time, this stimulated INP production in the water and INP emissions in sea spray.
Paper
Assessing the efficiency of water-soluble organic compound biodegradation in clouds under various environmental conditions
Biodegradation is competitive with photochemistry, especially in summer and at night. Formic acid is the most impacted compound.
Paper
Drone-based particle monitoring above two harmful algal blooms (HABs) in the USA
Little is known about the transport and fate of aerosolized particles associated with harmful algal blooms (HABs).
Paper
Emission of primary bioaerosol particles from Baltic seawater
Bioaerosols within sea spray are particles of biological origin with various important atmospheric implications. These particles were characterized here using novel single-particle spectroscopy and microbial community composition analysis.
Paper
Characterization of single fungal aerosol particles in a reactive atmospheric environment using time-resolved optical trapping-Raman spectroscopy (OT-RS)
We applied a time-resolved, optical trapping-Raman spectroscopy (OT-RS) technique to characterize single, trapped bioaerosol particles under well-controlled reactive conditions that mimic the native state of particles in the atmosphere.
Paper
Speech-generated aerosol settling times and viral viability can improve COVID-19 transmission prediction
Speech generates droplets averaged 6 μm in size. Their settling time and SARS-CoV-2 viral viability inside those droplets, both calculated from temperature and relative humidity, predict COVID transmission rates within one-sigma interval.
About this collection
In this gold open-access themed collection, we focus on bioaerosols, which are airborne particles that are living or originate from living organisms , such as bacteria, viruses, fungalspores and pollen.
Guest-edited by Cindy Morris (INRAE, Avignon), Xiaole Zhang (ETH Zurich), Malin Alsved (Lund University), Joshua Santarpia (University of Nebraska Medical Center), this broad collection highlights how bioaerosols can have significant impacts on human health, agriculture and ecosystems.
