TL;DR: In this article, the effects of several environmental parameters on bioaerosol concentrations were studied, such as rain events during monsoon and UV irradiation intensity during rain events, and the experimental measurements with limited variations of environmental conditions revealed that the phenomenon of the effect of rain on bio-aerosols might be caused by the transportation of bio-solols by falling raindrops from higher altitude to the ground, where the bio-osols accumulate, as well as by the decrease in UV irradiated intensity.
Abstract: Rain has been known to remove aerosol particles from the atmosphere; however, it was recently discovered that rain events during monsoon increase the concentrations of culturable bioaerosols in ground-level air environments. To explain this phenomenon, several hypotheses were tested via bioaerosol measurement experiments in this study. The experimental measurements with limited variations of environmental conditions revealed that the phenomenon of the effect of rain on bioaerosols might be caused by the transportation of bioaerosols by falling raindrops from higher altitude to the ground, where the bioaerosols accumulate, as well as by the decrease in UV irradiation intensity during rain events. We studied the effects of several environmental parameters on bioaerosol concentrations.

TL;DR: The results show that bioaerosol concentrations in hospitals were relatively high and in particular, the higher levels of bacteria than outdoor might be related to the presence of patients, their activity, unsuitable ventilation and disinfection.
Abstract: Background: Bioaerosol is defined as airborne particles such as living organisms include bacteria, viruses, fungi and their related metabolites, such as endotoxin. The exposure to bioaerosols in the hospital may causes infection especially in immunocompromised patients. The purpose of this study was to investigate the Bioaerosol concentrations in air of various parts of three hospitals of Isfahan University of medical sciences, Iran. Methods: An Anderson biosampler was used for the bacterial and fungal collection. The effect of factors such as humidity, temperature and outdoor Bioaerosol concentrations were also evaluated. Findings: The lowest mean of fungal and bacterial concentration was observed in hospital operating rooms and the highest concentration was detected in infectious diseases ward of hospital 1 and 2 and surgery ward of hospital 3. Significantly, bacterial levels were found to be higher in hospital wards than outdoor; except hospital operating rooms. Conclusion: Our results show that bioaerosol concentrations in hospitals were relatively high and in particular, the higher levels of bacteria than outdoor might be related to the presence of patients, their activity, unsuitable ventilation and disinfection. Therefore, environmental control measures are needed to assure hospital environmental quality especially in wards with immunocompromised patients.

TL;DR: A newly designed automatic bioaerosol sampler (ABS) was designed for studies of microbial bio-aerosols as discussed by the authors, which is the facility for unattended, microprocessor-controlled sampling with automatic replacement of the agar Petri dishes after each sample.
