In this study, various techniques for measurement and analysis of PAHs in the ambient air were verified in order to select a more reliable method. Sampling and analysis of PAHs were done by the EPA TO-13a method. QA/QC of the measurement was conducted to minimize errors in sampling and analyzing processes. The linearity of calibration curve of the PAH standards was good (R²≥0.99). Audit accuracy was evaluated using 5 internal standards of PAHs (Naphthalene-d?, Acenaphthene-d<SUB>10</SUB>, Phenanthrene-d<SUB>10</SUB>, Chrysene-d<SUB>12</SUB>, Perylene-d<SUB>12</SUB>). Relative standard deviations of the internal standard of the PAHs were ranged from 6.22% for acenaphthene-d10 to 8.11% for chrysene-d<SUB>12</SUB>. To evaluate the surrogate recoveries, two field surrogate standards of PAHs (fluoranthene-d<SUB>10</SUB>, benzo(a)pyrene-d<SUB>12</SUB>) and two extract surrogate standards of the PAHs (fluorene-d<SUB>10</SUB>, pyrene-d<SUB>12</SUB>) were spiked into all samples before field sampling and sample extraction, respectively. Recoveries of field the surrogate standards ranged from 80.4±12.2% for fluoranthene-d<SUB>10</SUB> to 66.2±12.8% for benzo(a)pyrene-d<SUB>12</SUB>. Extraction recoveries of the surrogate standards ranged from 70.4±10.2% for fluorene-d<SUB>10</SUB> to 77.6±10.8% for pyrene-d<SUB>10</SUB>. The detection limit of benzo(a)pyrene among 16 PAHs standards for quantitation was 20 pg.
