Abstract

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/$m^3$ with an average of 2.33 pg/$m^3$, 1.68~6.94 pg/$m^3$ with an average of 3.12 pg/$m^3$. These levels were lower than or similar to those of other countries.

본 연구에서 청주지역 대기 중 PFOA 및 PFOS의 오염수준을 조사하기 위해 공단, 주거/상업 및 농촌지역에서 각각 가스상 및 입자상 시료를 채취하였다. 또한 계절적 변화를 조사하기 위해 겨울철, 봄철 및 여름철에 각각 채취하였다. 대기 중 PFOA 및 PFOS의 농도는 각각 불검출~8.02 pg/$m^3$ (평균 2.33 pg/$m^3$)과 1.68~6.94 pg/$m^3$ (평균 3.12 pg/$m^3$)으로 검출되었다. 이들 농도는 외국과 유사하거나 낮은 수준을 보였다.
