초록

PIXE( Proton Induced X- ray Emission ) analysis has been applied to the analysis of aerosol for the Purpose of pollution monitoring. Coarse and fine Particle fractions were sampled selectively, using Nuclepore filter in stacked filter units, once a month from February to September in 1993 at urban and rural sites. Concentration of 9 elements, Si, S, K, Ca, Mn, Fe, Cu, Zn and Pb was determined without Pretreatment of Samples. Comparison of data between urban and rural site revealed higher elemental concentration level in urban aerosol. From April to May aerosol sampling was carried out daily to observe the effect of Yellow Sand on the composition of aerosol in the Korean Peninsula. During the Yellow Sand period, Si, Ca, Fe content level in aerosol became more than 5 times higher than normal. The elemental concentration of the aerosol samples of Daejeon City was compared with that of two foreign cities. S and Pb( which are fuel- derived elements) levels in Daejeon City aerosol appeared to be lower than those of foreign cities. And it may be due to the leaded-fuel restriction policy of Korean government since 1987.
