Source estimation of anthropogenic aerosols collected by a DRUM sampler during spring of 2002 at Gosan, Korea
AbstractContinuous measurements of trace elements in size-segregated aerosols were performed by X-ray fluorescence analysis in order to assess the transport of natural and anthropogenic aerosol sources to Gosan site in springtime 2002. Various aerosol elemental components (such as Al, Ca, Si, K, Ti, and Mn) had low enrichment factors close to one and exhibited a similar temporal variation in coarse particle range (2.5–12μm) indicating the dominant influence of soil dust. On the other hand, in the fine particle size range (0.09–2.5μm), several anthropogenic elements in ambient particles (such as As, Se, Zn, Pb, and Cu) revealed high enrichment (100Factor analysis was conducted with the size- and time-resolved aerosol composition data in order to identify anthropogenic sources of aerosols during non-Asian dust (NAD) period. As a result, it was found that the coarse particles were mainly influenced by soil, seasalt, coal combustion, and metallurgical emission and fine particles were significantly attributed to several anthropogenic sources, such as oil combustion, nonferrous metal source, and municipal incineration. Especially, submicron particles (0.09–0.56μm) were further impacted by motor vehicles and field burning emissions in addition to those sources.
