“…The harmfulness of biological factors in the Polish regulatory context is set out in the regulation dated 22 April 2005 on harmful biological factors for health in the work environment and the health protection of employees exposed to these factors [23]. On the other hand, the employer is obliged to assess occupational risk [24]. Workers in waste-sorting plants represent a group exposed to a particularly high health-risk associated with the presence of high concentrations of fungi and mesophilic bacteria [25].…”

An increased understanding of airborne microorganism populations should enable a better interpretation of bioaerosol exposure found in a working environment. An assessment of the contamination levels of mesophilic bacterial aerosol (MBA) and fungal aerosol (FA) was carried out using two evaluation indices for microbiological pollution—the total index of microbiological contamination per cubic meter (TIMC/m3) and the indoor–outdoor index (IOI). An advantage of selected indices is the inclusion of several co-existing factors that have an impact on the formation of bioaerosol. When properly used, they also highlight the low efficiency of the ventilation system caused by an insufficient air exchange. In this study, the microbial air quality (MAQ) of the working environment was assessed during the spring season at a sorting plant located in Southern Poland. Sampling was undertaken in the plant using an Andersen six-stage impactor which allows the obtainment of information about the size distribution of the air microflora. The value of average concentrations of MBA and the average concentration of FA collected in the preliminary cabin of the sorting plant (PCSP) and the cleaning cabin of the sorting plant (CCSP) were analyzed. The obtained values of MBA were 1.6 times higher indoors, compared to outdoors, while FA was 1.7 times higher outdoors than indoors. The maximum TIMC/m3 value was obtained in PCSP (2626). The calculated IOI in this study suggests that MBA concentrations are influenced by internal sources, as opposed to FA. The purpose of this work was to present the usefulness of using indices in assessing air quality.

“…The results hold that there are not only viruses and bacteria in the air with potential health risks, but also that both the mobility of air and air pressure make it more difficult to prevent these diseases. Due to the complexity and diversity of air microorganisms and their potential impact on air quality and human health (Brągoszewska, Biedroń, & Hryb, 2019), the topic of airborne microorganisms is very important and deserves more attention.…”

Bioaerosols are airborne particles of biological origin. In recent years, exposure to bioaerosols has caused significant public health concerns. This study aimed to provide a bibliometric analysis on global research trends of airborne microorganisms in recent ten years (2011-2020). Base on the web of Science (WoS) database, a total of 1087 papers in recent ten years are selected for analysis. Firstly, by analyzing the co-citation, 11 clusters were obtained, including potential pan microbiome, bioaerosol Science, beneficial microbe, urban area, Fungal microbiota, wastewater treatment plant, airborne microbial aerosol, modern practice, composting facilities-a review, airborne microbial biodiversity, and acidic electrolyzed water. Secondly, through the co-occurrence analysis of the keywords in the literature, it was proposed that particle-attached microorganisms, the community structure of urban air microbes, and biological aerosols are the research hotspots in recent years. This suggested that bioaerosol is a hotspot and current trend in the field of airborne microbiology, and the most studied airborne microorganisms are bacteria. In addition, we have also studied COVID-19 in particular, and found that the attention of COVID-19 has continued to rise in the past eight months, and the number of articles on the topic of COVID-19 has reached more than 19880 in the past eight months. Among them, 106 were highly cited. The co-occurrence analysis of COVID-19 was carried out with 500 articles published recently. Besides COVID-19, pandemics and coronavirus, the co-occurrence frequency of anxiety, depression and stress was high. Moreover, according to the number of published papers in this field,

International interests in biological air pollutants have increased rapidly to broaden the pool of knowledge on their identification and health impacts (e.g., infectious, respiratory diseases and allergies). Antibiotic resistance and its wider implications present us with a growing healthcare crisis, and an increased understanding of antibiotic-resistant bacteria populations should enable better interpretation of bioaerosol exposure found in the air. Waste sorting plant (WSP) activities are a source of occupational bacterial exposures that are associated with many health disorders. The objectives of this study were (a) to assess bacterial air quality (BAQ) in two cabins of a WSP: preliminary manual sorting cabin (PSP) and purification manual sorting cabin (quality control) (QCSP), (b) determine the particle size distribution (PSD) of bacterial aerosol (BA) in PSP, QCSP, and in the outdoor air (OUT), and (c) determine the antibiotic resistance of isolated strains of bacteria. Bacterial strains were identified on a Biolog GEN III (Biolog, Hayward, CA, USA), and disc diffusion method for antimicrobial susceptibility testing was carried out according to the Kirby–Bauer Disk Diffusion Susceptibility Test Protocol. A large share of fecal bacteria, Enterococcus faecalis and Alcaligenes faecalis spp. feacalis, was found in the tested indoor air, which is a potential health hazard to the workers of the monitored WSP. Our results demonstrate the necessity to take into account fecal air pollution levels to avoid making erroneous assumptions regarding the environmental selection of antibiotic resistance. Total elimination of many anthropogenic sources is not possible, but important findings of this study can be used to develop realistic management policies methods to improve BAQ.
