Abstract

Conidia of molds within the Asian dust were captured in the ambient air of mid-west Korea, in springtime of 2000~2002. An eight-stage Cascade impactor and 0.22 $\mu\textrm{m}$ pore size membrane filters were used for the dust samples. Several kinds of molds grown from the samples were identified to the genus level. Those are Aspergillus, Basipetospora, Epicoccum, Fusarium, Monotospora and Penicillium. Relatively diversified mycelia of hyphomycetes were grown on the fine dust sample (1.1~2.1 $\mu\textrm{m}$) in the first year Asian dust episode (23~24 March, 2000). On the other hand, some fluffy molds and dark molds aggregations were grown on even the backup particle sample less than 0.43 $\mu\textrm{m}$ during the second year episode (24~26 April, 2001). The result of the last year episode (21~22 March, 2002) showed various mycelia grown on the sample contained from 1.1 to 2.1 $\mu\textrm{m}$ sized particles, just like the result of the first year episode (23~24 March, 2000). These variations between the episodes might be caused by the difference of the dust origins.
