This research classifies the physical morphology (form and structure) of bioaerosols emitted from open windrow composting. Aggregation state, shape and size of the particles captured are reported alongside the implications for bioaerosol dispersal after release. Bioaerosol sampling took place at a composting facility using personal air filter samplers. Samples were analysed using scanning elect...

Exposure to bioaerosol from the premises of veterinary clinics poses a significant threat health staff and patient animals. Because pathogens airborne infections can be transmitted through it. The aim work was determine number mesophilic aerobic microorganisms in various during their operation under influence disinfection. Bioaerosol samples were collected using sedimentation method. seeded Pet...

Naturally occurring bioaerosol environments may present a challenge to biological detection-identification-monitoring (BIODIM) systems aiming at rapid and reliable warning of bioterrorism incidents. One way to improve the operational performance of BIODIM systems is to increase our understanding of relevant bioaerosol backgrounds. Subway stations are enclosed public environments which may be re...

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 in atmosphere.

conclusions the world health organization (who) has suggested relatively relaxed limits of 100 cfu/m3 for bacteria and 50 cfu/m3 for fungi in the hospital air. therefore, quantitative and qualitative outcomes of this study demonstrate that contamination level and bacterial variety in surgery rooms and emergency departments is high and effective measures must be taken to control the possible hea...
