This study is aimed to estimate the <TEX>$PM_{2.5}$</TEX> source apportionment at Seoul intensive monitoring site located in metropolitan area. Time-resolved chemical compositions of are measured real time using ambient ion monitor, semi-continuous carbon and on-line XRF 2010. The mass concentration was simultaneously monitored with eight ionic species (<TEX>${SO_4}^{2-}$</TEX>, <TEX>$NO_3{^-}$</TEX>, <TEX>$Cl^-$</TEX>, <TEX>$NH_4{^+}$</TEX>, <TEX>$Na^+$</TEX>, <TEX>$K^+$</TEX>, <TEX>$Mg^{2+}$</TEX>, <TEX>$Ca^{2+}$</TEX>), two carbonaceous (OC EC), fourteen elements (Si, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, As, Se, Pb) 1-hr interval. data sets were then analyzed EPA PMF version 3 identify sources contributions mass. modeling identified PM2.5 sources, including soil dust, secondary sulfate, nitrate, motor vehicle, coal combustion, oil biomass burning, municipal incineration. found that average apportioned anthropogenic such as fuel burning (61%) aerosols, sulfate nitrate (38%).
