We conducted a principal component analysis of PM2.5 (particles with a diameter ≤ 2.5 μm) at four sites locatedin Chungcheongnam-do, a province of South Korea, to determine the level of pollution and characteristics ofPM2.5 components at each emission source. The four monitoring sites included a steel complex near Songsanmyeon(SS) area, a petrochemical complex near Dokgot-ri (DG) area, a residential complex near Mojong-dong(MJ) area, and a village near Naepo (NP) area. Samples collected at these sites were analyzed and the concentrationsof mass, ion, carbon, and element in PM2.5 were compared. The mass concentrations were found tobe the highest in SS, followed by MJ, DG, and NP. The concentration of dominant ion species were recorded ina ascending order of NO3- > SO42+> NH4+ in MJ and SO42- > NO3- > NH4+ in SS, DG, and NP. The results indicatethat MJ had the highest NOx concentration, which is emitted by automobiles. Moreover, MJ exhibited the highestorganic carbon concentration of 5.67 μg/m3 and elemental carbon concentration of 0.51 μg/m3. The analysis ofthe elemental composition of PM2.5 indicated a significantly higher concentration of Fe, Zn, and Mn in SS andAs, V, and Ni in DG. Different component analysis results from each emission source suggest the need to understandthe distribution of pollutants in each region while establishing measures to reduce PM2.5 levels.
Abstract
We conducted a principal component analysis of PM2.5 (particles with a diameter ≤ 2.5 μm) at four sites locatedin Chungcheongnam-do, a province of South Korea, to determine the level of pollution and characteristics ofPM2.5 components at each emission source. The four monitoring sites included a steel complex near Songsanmyeon(SS) area, a petrochemical complex near Dokgot-ri (DG) area, a residential complex near Mojong-dong(MJ) area, and a village near Naepo (NP) area. Samples collected at these sites were analyzed and the concentrationsof mass, ion, carbon, and element in PM2.5 were compared. The mass concentrations were found tobe the highest in SS, followed by MJ, DG, and NP. The concentration of dominant ion species were recorded ina ascending order of NO3- > SO42+> NH4+ in MJ and SO42- > NO3- > NH4+ in SS, DG, and NP. The results indicatethat MJ had the highest NOx concentration, which is emitted by automobiles.
