“…3). After referring to Khattab and Levetin (2008) regarding sampling height difference and fungal spore concentration, the Aspergillus/Penicillium concentration in the present study was expected to be lower because of the higher sampling height (15 m above the ground) than that used by Chen et al (2.5 m above the ground); however, our results revealed a higher Aspergillus/Penicillium concentration. The possible reasons for this result include different sampling locations, nearby land utilization, and changes in meteorological and environmental conditions over the past few years, as has been reported by many studies (Ding et al, 2016;Kuo et al, 2016;TCCIP, 2016;Tung et al, 2016).…”

Ambient particles comprise approximately 25% of fungal spores, which cause adverse health outcomes such as respiratory diseases, allergy, and infection. In this study, we investigated temporal variations and distributions of ambient fungal spores in an urban area of the Taipei metropolis for over 1 year. A Burkard 7-day volumetric spore trap was used to collect air samples. Samples collected daily were stained, counted, and identified on the basis of morphological characteristics. The associations between fungal spores and environmental parameters were then evaluated through multiple regression analysis. Daily monitoring data revealed a large variation in fungal spore concentrations. Specifically, fungal spores peaked during summer months (June-August) and declined during winter months (December-early March); moreover, the average concentration of total fungal spores was 3,607.97 ± 3,181.81 spores m -3 . Ascospores were the most prevalent taxon that was recovered from the samples, followed by basidiospores, Aspergillus/Penicillium, and Cladosporium. Multiple regression analysis revealed that meteorological parameters were the main predictors of fungal concentrations. Temperature, wind speed, and humidity were consistently correlated with total fungi and major fungal taxa, and sunlight had a negative association with ascospores. Among the atmospheric pollutants, particulate matter with an aerodynamic diameter ≤ 10 µm (PM 10 ) and ozone were positively associated with fungal spores. Carbon monoxide (CO) at lag day 1 had a negative association with basidiospores. This is the first study to characterize daily concentrations and determinants of ambient fungal spores in an urban area of Taipei metropolis. The obtained data can be used to evaluate the health impact of fungal spore exposure on the residents of the Taipei metropolitan area.

“…In Al-Subai (2002) study, 1% glucose-Czapek's agar + 0.05% yeast extract culture medium, while in this study Potato Dextrose Agar (PDA) was used as a culture medium. Both, the height level of collection and culture media used are considered variables that affected the species composition and abundance of air mycoflora (Burge et al, 1977;Herrero et al,.1996;Khattab & Levetin, 2008 ). The above differences in the methodology of the two studies as well as the long Abdel-Hafez, 1984;Al-Subai, 2002;Sen & Asan, 2009;Abu-Dieyeh et al, 2010;Quintero et al, 2010;Shams-Ghahfarokhi et al, 2014).…”

“…Pollen ratio higher than 1 were 230 expected according to the reviewed literatureXiao et al, 2013), as pollen 231 concentrations decrease with height. However, this behavior was not observed for all reviewed 232 cases, possibly due to the influence of other factors than height as discussed below(Borycka and 233 Kasprzyk, 2018;Bryant et al, 1989;Khattab and Levetin, 2008). 234235Not only the height difference between paired pollen stations is important.…”
