Emissions of Bioaerosols from Composting Facilities
… major public health concerns is the emissions of bioaerosols from the composting sites. Bioaerosol dispersion across composting facilities, due to operational activities, may have significant effects on human health due to the fact that they can penetrate into the human respiratory system leading …

Catching a glimpse: the visualization of Mycobacterium tuberculosis from TB patient bioaerosols
Transmission between hosts is crucial for the success and survival of the obligate human pathogen and aetiological agent of tuberculosis (TB), Mycobacterium tuberculosis (Mtb). Despite this, little is known about how and when Mtb is aerosolized nor the key metabolic and morphological determinants …

Matrix-assisted laser desorption/ionization mass spectrometry for the analysis of collected bioaerosols
… and identification of microorganisms from bioaerosols using offline matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) for the analysis of proteins. MALDI-MS intact bacteria techniques were adapted for use with an orthogonal MALDI quadrupole-time-of-flight mass …

Development and Characterization of an Inexpensive Single-Particle Fluorescence Spectrometer for Detection and Classification of Pollen and Other Bioaerosols
<p>Atmospheric aerosols are ubiquitous throughout the Earth’s atmosphere and can be important with respect to environmental systems and human health. Pollen particles are a class of primary biological aerosol particles (PBAPs) that cost the United States billions of dollars a year in loss of …

Fluorescent Biological Aerosol Particles in Coastal Canada and the Link to Atmospheric Ice Nuclei
<p>Bioaerosols are a subgroup of atmospheric aerosols and are often linked to the spread of human, animal and plant diseases. Bioaerosols also may play an indirect effect on environmental processes, including the formation of precipitation and alteration of the global climate through their role as …

Quantification of Airborne Fungal Spores Comparing Molecular Tracers via Ion Chromatography and UV-LIF Methods
… spores represent an understudied subcategory of bioaerosols that can impact human health as pathogenic and allergenic particles. Fungal spores also have been shown to act as effective ice nuclei and giant cloud condensation nuclei in some cases. This has implications on the hydrological cycle on …

Bioaerosol Dispersal Across Scales: Regional Patterns, Field Study, and Model Evaluation
Bioaerosols--including seeds, pollen, fungal spores, bacteria, and viruses--are fundamental agents connecting atmospheric processes to agriculture, ecosystem function, and human and animal health. This dissertation uses Lagrangian stochastic (LS) models to simulate how these particles travel and …

Airflow in Interior Spaces: Implications on Comfort and Health
… Finally, this work looks at dispersion of bioaerosols within a classroom environment. Via simulations, this work contributes through the quantification of different ventilation approaches and generalizable recommendations for contaminant control at the breathing zone.

Comparative analysis of bacterial and fungal communities in two dairy parlors through the use of pyrosequencing, riboprinting, culture techniques, and microscopic analysis
The purpose of this study was to compare three different analysis techniques used to characterize and identify bacteria and fungi. Pyrosequencing, culture techniques, and riboprinting were compared for all of the bacterial samples and pyrosequencing; culture techniques; and microscopic analysis was …

Spray Aerosols From Saltwater to Freshwater Breaking Waves
While sea spray aerosols (SSAs) generation by oceanic breaking waves continues to be an active research area, lake spray aerosols (LSAs) production by freshwater breaking waves is an emerging research field. Recent studies have linked LSAs to regional cloud processes and the aerosolization of …
