AB  - Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous pollutants worldwide; 
      currently, they are being described as potential persistent organic pollutants 
      (POPs). This study is aimed to identify sources of PAHs in the atmosphere around 
      the Sihwa and Banwol industrial area by using diagnostic ratios and multivariate 
      factor analysis such as principal component analysis/absolute principal component 
      score (PCA/APCS) and positive matrix factorization (PMF). The atmospheric PAHs 
      level was 8.07-177 ng/m(3) (gaseous phase: 5.93-68.4 ng/m(3); particulate phase: 
      1.85-128 ng/m(3)) and PAHs concentration in the warm period was lower than the 
      cold period. As a result of the examination of relative BaP concentration, 
      photodecomposition was found not to be an important factor in the seasonal 
      difference of PAHs concentration in this study. Source identification was first 
      carried out through a double ratio plot. As a result of double ratio plots, 
      atmospheric PAHs in this study were found to stem from the combination of 
      vehicular emission, combustion (coal or biomass-wood or grass), and petroleum. 
      Moreover, PCA/APCS and PMF showed that the main sources were vehicular emission 
      and coal combustion and and incineration-related source with a summed 
      contribution of about 72.6-86.7%. Finally, the fitness of the two models was very 
      good; the estimated values were highly correlated with the measured values (R(2) 
      = 0.991-0.999, p < 0.05).
