To investigate pollution level of PFOA and PFOS in ambient air, Cheongju city, gaseous and particulate samples were collected at industrial, residential/commercial, and rural region, respectively. Samples were collected in winter, spring, and summer season in order to examine seasonal variation of PFOA and PFOS. The concentration range of PFOA and PFOS was presented as N.D.~8.02 pg/㎥ with an average of 2.33 pg/㎥, 1.68~6.94 pg/㎥ with an average of 3.12 pg/㎥. These levels were lower than or similar to those of other countries.
