[Ecological distributions of airborne fungi in outdoor environments in Beijing, China].
An investigation on fungal types, concentrations, and their dynamic variation in outdoor environments was carried out in three different functional areas around one year in Beijing. Results show that the fungal concentrations varied widely and the average was (1164.8 +/- 73.2) CFU x m(-3), ranging from 23.6CFU x m(-3) to 13 959.5 CFU x m(-3). The most common culturable airborne fungi in all seasons and all functional areas were Cladosporium , nonsporulating fungi, Alternaria, Penicillium and Aspergillus. The most dominant fungus was Cladosporium, which contributed to more than 1/3 of the total. The fungal levels in culture and education region (CER) and garden green region (GGR) were highest in the fall and summer, and lowest in the winter and spring, while the seasonal variation in main traffic line (MTL) was not significant. The fungal concentrations in CER and GGR were significantly higher than in MTL (p <0.05). No statistically significant difference exists between CER and GGR.
