This study developed a method for an improved measurement of PAHs concentrations in the atmosphere using two PUF PAS and two low-volume air samplers (LVAS), and thereby measured and characterized the seasonal concentrations of PAHs in the atmosphere of Anseong area using PUF PAS. It was better to use correlation between the concentrations from LVAS and those from PUF PAS, whereby analysis errors were reduced, than to use sampling rates (m3/day), in the procedure of determining PAHs concentrations in the atmosphere using PUF-PAS. The seasonal PAHs concentrations in the atmosphere were 7.77 ng/m3 in winter, 3.72 ng/m3 in spring, 2.86 ng/m3 in fall and 1.78 ng/m3 in summer, and peak concentrations of Pen, Flt, and BbF were shown. The seasonal toxic equivalency (TEQ) were 0.1625 ng-TEQ/m3 in spring, 0.0826 ng-TEQ/m3 in winter, 0.0499 ng-TEQ/m3 in fall and 0.0481 ng-TEQ/m3 in summer, the order of which was different from that of concentrations, and peak TEQs of Flt, BbF, BaP, and DahA were shown. Because PAHs are a toxic issue, it is considered better to write their TEQ than their concentration, just like PCDD/Fs. Comparing the results of this study with the PAHs concentrations measured by the Ministry of Environment in Anseong as this study in the same period, confirmed that collecting atmospheric samples in a short period using HVAS would be greatly affected by local pollution.
