Bursting bubbles are one of the most common mechanisms in aerosols’ formation from natural and artificial waterbodies. The presence microbial materials liquid could cause their aerosolization generation bioaerosols. process depends on a number parameters gas involved. This project investigated influence air flow, bubble size, temperature its surface tension efficiency bioaerosol generation. It ...
Intensive poultry production, implying large densities of animals in small areas, is a significant source of air pollution which may constitute a considerable health hazard to the birds, farmers and those living in the proximity of the farm (Lonc & Plewa, 2009). On the other hand, the spread of bioaerosols on the outside of animal housing may result in local or even more extensive environmental...
The use of biological safety cabinets (BSCs) in laboratories has greatly increased over the last few decades. BSCs are used in laboratories to protect both the scientists and the experiments from contamination by biological hazards during tissue culture procedures. The function of BSCs depends upon the HEPA filtration, the fan performance and the airflow patterns in the cabinet. To ensure BSCs ...
We propose using the surface of pine trees needles to biomonitor the bioaerosol emissions at a composting plant. Measurements were based on 16S rRNA gene copy numbers of Saccharopolyspora rectivirgula, a bioindicator of composting plant emissions. A sampling plan was established based on 29 samples around the emission source. The abundance of 16S rRNA gene copies of S. rectivirgula per gram of ...
Air is filled with numerous tiny organisms, with sizes ranging from 50 nm to 10 μm. These organisms are called airborne biological particles or bioaerosols. In the human history of investigating the origin of life and fighting against contagious diseases, the recognition of bioaerosols and the development of control methods against them have played crucial roles. The pandemic outbreak of flu du...
