Bioaerosol concentrations generated from toilet flushing in a hospital-based patient care setting

Antimicrobial Resistance and Infection Control, 2018
Background In the United States, 1.7 million immunocompromised patients contract a healthcare-associated infection, annually. These infections increase morbidity, mortality and costs of care.

Atmospheric Microbial Transport to Antarctica and Its Ecological Implications: A Systematic Review

Environmental Microbiology, Volume 28, Issue 9, September 2026.
Atmospheric transport to Antarctica operates via long‐range advection, marine aerosolization, and local resuspension, acting as a strict ecological filter. This selective barrier could actively shape local ecosystems by seeding them with functionally distinct, stress‐adapted microbial pioneers capable of surviving extreme conditions.

Hidden Mould in the Air: A Practical Narrative Mini‐Review of Invasive Mould Infection Prevention for High‐Risk Patients and Clinicians

Mycoses, Volume 69, Issue 9, September 2026.
ABSTRACT Airborne mould spores, including those of the Aspergillus species, are ubiquitous both indoors and outdoors. While they are generally harmless, inhaled spores can cause severe infections, particularly invasive pulmonary aspergillosis, in patients with impaired immune defences.

Characterization and parameters for the effectiveness of a UV‐C device for infection control in dental clinics

Photochemistry and Photobiology, Volume 102, Issue 5, Page 1100-1111, September/October 2026.
Purpose‐built UV‐C device achieves over 90% disinfection of high‐touch dental clinic surfaces. Abstract Healthcare‐associated infections (HAIs) remain a significant concern in dental settings, especially in light of increasing antimicrobial resistance.

Lidar Ratios and Fluorescence Properties of Stratospheric Volcanic Sulfate

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract From January to June 2025, a stratospheric sulfate layer originating from the eruptions of the Ruang volcano in April 2024 could be observed with a multi‐wavelength Raman and fluorescence lidar over Leipzig, Germany. The aerosol‐optical depth of the stratospheric volcanic sulfate was <0.02 ${< } 0.02$, decreasing with time.

Exploring toilet plume bioaerosol exposure dynamics in public toilets using a Design of Experiments approach

Scientific Reports
Bioaerosols generated during toilet flushing can contribute to the spread of airborne pathogens and cross-contamination in indoor environments. This presents an increased risk of fomite-mediated or aerosol disease transmission.
