TL;DR: In this paper, the authors evaluated whether the visible growth of mold indoors influences the concentration of fungal spores in the air as well as the variety of their species, and found that the extent of visible mold growth is significantly correlated with both the fungal species and the amount of spores.

TL;DR: The content of fungal spores in air is characterized by a specific seasonal and diurnal cycle which depends on climate and weather conditions, on the accessibility of fresh substrates for the development of the fungus, circadian cycle of light and darkness, and other environmental hardly definable factors.
Abstract: Fungal spores occur very numerously in the air and, on account of their di- mensions (several micrometers), are classed as bioaerosols. They are always observed in natural air and their concentration changes depending on environmental conditions. Aero- mycology investigates their occurrence in the air of the indoor-outdoor environment. The methods of sampling can be divided into the gravimetric method when the spores fall onto a catching surface by force of gravity, and the volumetric method consisting of analysis of spores contained in a given air unit. The content of fungal spores in air is characterized by a specifi c seasonal and diurnal cycle. Among other things, these cycles depend on climate and weather conditions, on the accessibility of fresh substrates for the development of the fungus, circadian cycle of light and darkness, and other environmental hardly defi nable factors. Many fungi undesirably affect human health, cause immunotoxic diseases, and are a frequent cause of allergic diseases. Knowledge of concentrations of airborne fungal spores is especially important for agricultural and occupational medicine. Aeromycology has its application in agrobiology, particularly with respect to pathogenic fungi, and in the conservation of the artistic heritage.

TL;DR: Analysis of the partitioning behavior of two pathogens and several common indicator organisms in natural waters under both dry and wet weather conditions found the highest microbial concentrations, in both particle-associated and free phase, occurred during the earlier stages of a storm.

TL;DR: In this paper, the authors investigated the physical and biological parameters affecting overall performance of portable microbial samplers when collecting different bioaerosol species, including impaction velocity from 1 to 15m/s and jet-to-plate distance from 1.7 to 6mm.

TL;DR: In this paper, the authors assess worker and community exposure to bioaerosols emitted from a suburban yard waste composting facility in northern Illinois, USA through a total of 288 on-and off-site Andersen samples conducted over 10 sampling days.
Abstract: The purpose of this study was to assess worker and community exposure to bioaerosols emitted from a suburban yard waste composting facility in northern Illinois, USA. Characterization of on- and off-site viable bioaerosols was undertaken through a total of 288 on- and off-site Andersen samples conducted over 10 sampling days. A total of 46 dust samples and 38 Kramer-Collins spore samples were also collected in this period. Evaluation of the impact of the facility on community bioaerosol concentrations was undertaken by comparing on- and off-site measurements by sampling locations, wind direction, and site activity. On-site concentrations of total spores, Aspergillus/Penicillium spores, total bacteria, Gram-positive bacteria, Gram-negative bacteria, actinomycetes, total SDUWLFXODWHVHQGRWR(LQDQG-1,3 glucans were higher than off-site concentrations. Total fungal spores averaged 13,451 spores/m 3 (range 5,223-26,067) on-site and 8,772 spores/m 3
