Summary: Indoor fungal air concentrations are significantly correlated with outdoor concentrations, but a high surface fungal density does not necessarily lead to high airborne fungal concentrations. Therefore, quantification of the surface fungal area is recommended to assess the risk of surface fungi propelling into the air.

Summary: This study reveals the significant impact of vegetation and land use on airborne spore concentrations, especially in cases of long-medium distance transport. The results demonstrated spatial variation in spore concentrations between two close localities, attributed to prevailing winds and different land cover types. The importance of land cover and wind data for establishing spore transport routes and improving forecasting models is highlighted, emphasizing the need for local-level Alternaria aerobiological studies.

Summary: This study evaluated fungal aerospora in one outdoor and six indoor microenvironments in Kolkata, India using microscopy-based and culture-based methods. The correlation between environmental parameters and spore concentrations was assessed, and the impact on the local population was evaluated through a questionnaire survey and Skin Prick Test. The results revealed that outdoor spore concentration was the highest, and different major fungal taxa were identified using microscopy-based and culture-based methods. The association between spore concentrations and respiratory diseases provides insights into air quality and the increasing burden of airway diseases in the urban megacity of Kolkata.

Summary: Monitoring airborne inoculum can provide early warning of disease risk for growers, helping them adapt to changes in management tools and reduce fungicide use. Understanding particle transport in plant canopies and pathogen-specific biology is crucial for effective use of inoculum monitoring. The placement of air samplers should consider the complexity of the pathosystem and local environment.

Summary: This study investigated the vertical variations in the concentration and community structure of airborne bacteria at different heights in Xi'an, China. The results showed a decrease in microbial concentration with increasing height on polluted days, while no significant difference was observed at different heights on non-polluted days. Additionally, meteorological factors had a more significant impact on the bacterial community at higher altitudes compared to lower altitudes.

Summary: This study investigates the changes in airborne metal concentration in Baltimore, Maryland between 2001 and 2019, with a focus on the urban industrial community of Curtis Bay in South Baltimore. The findings indicate that industrial decline and proximity to traffic emissions are the main factors affecting metal concentration. The study also highlights the impact of municipal incinerators on metal concentration.

Summary: This study conducted a Quality Control exercise for fungal spore monitoring in Europe, suggesting that analyzing about 5% of the slide (two transects in this study) yields comparable results to analyzing five transects. The coefficients of variation for Alternaria and Epicoccum were within acceptable limits, with no significant differences observed between different numbers of transects analyzed.

Summary: Forest diseases caused by invasive fungal pathogens are on the rise, making the development of early detection systems crucial. Windborne spores play a key role in introducing fungal pathogens to new areas, and the design of spore trapping devices coupled with efficient molecular detection methods can help forest managers anticipate and prevent new disease outbreaks. Combining spore trapping with high-throughput sequencing for detection shows promise as a diagnostic tool for invasive fungal pathogens.

Summary: This systematic review analyzes the seasonality of outdoor fungal spores in Europe and its implications for health. The study found that Alternaria and Cladosporium were the most commonly reported genera, with longer seasons in Mediterranean regions. Meteorological variables and land-use were identified as the main factors influencing fungal seasonality. Further research is needed to address knowledge gaps and improve understanding and management strategies for fungal allergies.

Summary: This study found that individuals with higher CFU counts in the home had more severe MG dropout, after adjusting for age and other confounders. This finding suggests that home CFU exposure may impact MG dropout, one of the DE measures, and may be a target for intervention.

Summary: This study found that certain species of fungi are influenced by magnetic fields, and this should be considered in studies on airborne fungi and air quality. The research showed that the oscillating magnetic field significantly affected the colony size and mycelia pigmentation of Aspergillus niger, but had less impact on Cladosporium cladosporioides and Penicillium citrinum.

Summary: This study aimed to bridge the gap between lack of awareness and understanding of how occupant behavior affects indoor air quality (IAQ). An evaluation of IAQ awareness and an investigation of an eco-feedback strategy were conducted. The results showed that occupants were not properly aware of IAQ in their homes, but the eco-feedback strategy successfully promoted behavioral changes and reduced particle concentration during cooking activities.

Summary: This paper provides a review of indoor fungal contamination, specifically focusing on the aerosolization of fungal spores. It summarizes the current understanding and identifies the need for more information to predict spore aerosolization. Prediction methods for spore aerosolization are discussed, clarifying the current situation and future efforts required for accurate prediction. This information is valuable for forecasting and controlling the aerosolization of fungal spores.

Summary: The traditional wet dust removal technology is ineffective in removing fine particles with low concentration. Therefore, it is vital to explore a purification technology for low concentration of fine particles. A pilot-scale experimental system employing a cross-flow rotating packed bed was set up to explore the purification capacity of high gravity wet dust removal technology for low concentration fine particles.

Summary: The study evaluated the characteristics of particulate and gaseous pollutants produced by a household laser processing equipment, finding that the mode diameters of emitted particles decreased and particle number concentration increased with higher laser power. Additionally, increasing the sheath air flow rate resulted in a decrease in mode diameter of emitted particles but had little effect on particle number concentration.

Summary: This study aimed to quantitatively evaluate the effects of air purifiers on the spread of COVID-19 and suggested guidelines for their safe use. The results showed that while the air purifiers had little impact on the spread of simulated respiratory droplet nuclei, they significantly affected the spread of nano-sized virus aggregates. The constant operation of air purifiers with HEPA filters reduced the concentration of both simulated respiratory droplet nuclei and nano-sized aggregates, indicating their effectiveness in reducing airborne particles.
