“…On the other hand, the next most frequently detected genera Acremonium, Paecilomyces, Cladosporium, Rhizopus predominated only in one season (Figure 4). Larsen and Gravesen [33] recorded the same seasonal patterns of genera Penicillium, Aspergillus and Cladosporium in the long-term study which was conducted in an outdoor environment.…”

“…The species composition may be influenced by microscopic fungi from waste as well as airborne fungi from the outside environment, that penetrate through doors and windows. The most frequently isolated fungi from outside environment are those of the genera Penicillium, Aspergillus, Cladosporium and Alternaria [33][34][35]. Genera Penicillium and Aspergillus dominated in this study in all seasons.…”

Background: In working environment of waste treatment facilities, employees are exposed to high concentrations of airborne microorganisms. Fungi constitute an essential part of them. This study aims at evaluating the diurnal variation in concentrations and species composition of the fungal contamination in 2 plastic waste sorting facilities in different seasons. Material and Methods: Air samples from the 2 sorting facilities were collected through the membrane filters method on 4 different types of cultivation media. Isolated fungi were classified to genera or species by using a light microscopy. Results: Overall, the highest concentrations of airborne fungi were recorded in summer (9.1×10 3 -9.0×10 5 colony-forming units (CFU)/m

“…The dominance of this genus over other spores has been observed in many locations, including Denmark (Larsen, 1981;Larsen & Gravesen, 1991), Spain (Infante & Dominquez, 1988;Infante et al, 1992), Italy (Cosentino et al, 1990;Marchisio et al, 1997), Austria (Ebner et al, 1992), Jordan (Shaheen, 1992), Sweden In bold -highest monthly concentrations.

“…Alternaria spore levels are relatively high compared to most other spore types and their numbers were highest during July and August. The highest numbers of Alternaria spores are usually encountered during the summer in Poland (Gaweł et al, 1996;Kasprzyk et al, 2004;Konopiń ska, 2004;Stępalska & Wołek, 2005), Denmark (Larsen & Gravesen, 1991) and Sweden (Hjelmroos, 1993).…”

The investigation of airborne fungal spore concentrations was carried out in Szczecin, Poland between 2004 and 2006. The objective of the studies was to determine a seasonal variation in concentrations of selected fungal spore types due to meteorological parameters. The presence of spores of ten taxa: Cladosporium, Ganoderma, Alternaria, Epicoccum, Didymella, Torula, Dreschlera-type, Polythrincium, Stemphylium and Pithomyces was recorded in Szczecin using a volumetric method (Hirst type). Fungal spores were present in the air in large numbers in summer. The highest concentrations were noted in June, July and August. The peak period was recorded in August for most of the studied spore types: Ganoderma, Alternaria, Epicoccum, Dreschlera-type, Polythrincium and Stemphylium. Cladosporium and Didymella spores reached their highest concentrations in July while concentrations of Torula were highest in May and Pithomyces in September. Multiple regression analysis was performed for three fungal seasons: 2004, 2005, and 2006. Spore concentrations were positively correlated with minimum temperature for seven spore types in 2004, for five spore types in 2005, and for eight spore types in 2006 (significance level of a50.05). Some spore types are also significantly correlation among their concentrations, pressure, relative humidity and rain. Minimum temperature appeared to be the most influential factor for most spore types.

“…May be it is a reason why we found a significantly lower concentration of Cladosporium in autumn, in comparison with the spring. Seasonal differences in outdoor spore concentrations have been observed by others authors (Larsen and Gravesen, 1991;Mitakakis et al, 1997;Fernández et al, 1998;MedrelaKuder, 2003).…”

Samples of house dust from 18 flats in Warsaw (Poland) were collected from five environments: floor, shelves with books, kitchen, bathroom, and bed. Penicillium, Aspergillus, Cladosporium and Alternaria were the most common genera identified in house dust samples. The highest culturable fungal concentrations were recorded in dust from shelves (median value 8.2 × 10 4 CFU/g of dust), and the least one from beds (median value 8.0 × 10 3 CFU/g of dust). Differences in CFUs between environments were statistically significant for Penicillium, Aspergillus and Alternaria. Concentrations of Penicillium and Aspergillus were significantly higher in autumn than in spring, whereas that of Cladosporium was significantly lower in autumn than in spring. The efficiency of ventilation in the bathroom had a significant effect on Cladosporium counts. Certain relationships between the concentrations of culturable fungi and some customs of the occupants are discussed.
