Abstract Bioaerosol particles in the stratosphere are topics of interest for aerobiological and astrobiological studies. Although various studies have succeeded sampling bioaerosol stratosphere, limited research has been conducted to evaluate how why these can lift up as high stratospheric level. This study tested different driving forces acting on order simulate motion with characteristics. Th...

INTRODUCTION As bioaerosol research attracts increasing attention, there is a need for additional efforts that focus on method development to deal with different environmental samples. Bioaerosol environmental samples typically have very low biomass concentrations in the air, which often leaves researchers with limited options in choosing the downstream analysis steps, especially when culture-i...

Work-associated lower airway inflammation in waste collectors was examined by induced sputum and correlated with the bioaerosol exposure. Organic waste collectors (n=25) underwent induced sputum collection and spirometry before work on Monday and the following Thursday. Total cells, cell differentials, interleukin (IL)-8 and eosinophilic cationic protein were determined. Personal full-shift exp...

OBJECTIVES The aim of this study was to assess exposure to airborne endotoxins and peptidoglycans (PGs) as well as possibility of using PGs as a surrogate measure of bacterial exposure in workplaces in a metal processing plant. MATERIAL AND METHODS Personal dosimetry (N = 11) was used to obtain data on concentrations of viable bacteria, total number of bioaerosol particles, endotoxins and pep...

As a bioaerosol sampling standard, Andersen type impactor is widely used since its invention in 1950s, including the investigation of the anthrax attacks in the United States in 2001. However, its related problems such as impaction and desiccation stress as well as particle bounce have not been solved. Here, we improved its biological collection efficiencies by plating a mineral oil layer (100 ...

Abstract. Bioaerosols are usually defined as aerosols arising from biological systems such bacteria, fungi, and viruses. They play an important role in atmospheric physical chemical processes including ice nucleation cloud condensation. As such, their dispersion affects not only public health but also regional climate. Lidar is effective technique for aerosol detection pollution monitoring. It ...

Bioaerosol research often requires stable and reliable aerosol generators that could produce high particle concentrations. However, there is still a lack of information about the effect of aerosolization on the physiological status of microorganisms. Here we tested the performance of several liquid bioaerosol generators including a Collison nebulizer, a LiquidSparging Aerosolizer (LSA), a C-flo...

AIMS The aim of this project was to validate a method to deliver a reproducible, selected dose of infective bioaerosol through a respiratory protective technology to an animal that exhibits a proportional clinical response. METHODS AND RESULTS The Controlled Aerosol Test System (CATS) was designed to generate and condition a viable infective aerosol, pass it through a treatment technology and...

background: most rural carpet weaving workshops are part of the house and sanitary conditions of the workshop not only affect the weaving but also other family members this study aimed to determine the aerosol and bioaerosols concentration in the rural household carpet weaving workshops in isfahan. methods: in this this study is a cross - sectional study and was performed in 92 rural household ...
