| ABSTRACT |
|
In order to assess the pollution status and distribution characteristics of PM and PM-bound species, PM10 samples were collected using mini-volume air sampler at the subway cabin in Daejeon city. Measurements of about 24 elements including toxic metals (e.g., As, Cr, Mn, V, Zn) in PM10 were made by instrumental neutron activation analysis and X-ray fluorescence. The average PM10 concentration was 59.3 ± 14.5 µg/m3 in the subway cabin with a range of 42.2 to 97.4 µg/m3, while the associated elemental concentrations were varied in the range of 10-3 to 105 ng/m3. It was found that the concentration of Fe (12.5 µg/m3) was substantially higher than any other element. The Fe concentration was apportioned by about 20% of the PM10 concentration. The results of factor analysis indicate that there are no more than six sources in the cabin (e.g., brake-nonferrous metal particle, resuspended rail dust, fuel combustion, vehicle exhaust, black carbon, Cr-related). |
