The purpose of this study was to characterize background mass concentration of PM₁?, PM<SUB>2.5</SUB> and metallic composition from June 2004 to June 2005 in comparison with Seoul and Asan city.
The results were as follows:
1. Annual mean of PM₁₂ concentrations in Seoul and Asan were 56.95(±25.63)㎍/㎥, 57.02(±27.22)㎍/㎥ respectly.
2. Annual mean of PM<SUB>2.5</SUB> concentrations in Seoul and Asan were 46.97(±40.36)㎍/㎥, 42.16(±21.79)㎍/㎥ respectly.
3. The average PM<SUB>2.5</SUB>/PM₁? ratio was 0.82 in Seoul and 0.74 in Asan city.
4. The concentration of PM₁?, PM<SUB>2.5</SUB> were the highest in spring and the lowest in summer. Asan was higher than Seoul in spring and summer.
5. The results showed that average PM₁? composition order as Si>Fe>Pb>Zn>]Mn in Seoul and Si>Fe>Zn>Pb>Mn in Asan. The concentration of metals in PM₁? of Seoul that Cr, Cu, Fe, Mn were high in spring and Zn was low in Fall. Fe, Mn were high in spring of Asan.
6. The results showed that average PM<SUB>2.5</SUB> composition order as Si>Pb>Fe>Zn>Mn in Seoul and Si>Fe>Pb>Zn>Cr in Asan. The concentration of metals in PM<SUB>2.5</SUB> of Seoul that Cr was high in spring.
7. The result showed that relation between Cr and Cu, Cu and Fe, Fe and Mn, Mn and Zn, Zn and Si in Seoul, Cr and Zn, Cu and Pb, Zn and Pb, Pb and Mn in Asan.
The result showed that PM₁? concentration exceeding 50㎍/㎥(US-EPA Standard) and PM<SUB>2.5</SUB> concentration exceeding 15㎍/㎥(US-EPA Standard).
In urban area, the monitoring of PM<SUB>2.5</SUB> permits the anthropogenic sources and the interference of natural sources with respect to PM₁? measurements.
