The annular denuder system (ADS) was used to quantitatively determine the relationship between indoor and outdoor air. All indoor and outdoor measurements were done simultaneously using the ADS in Chongju, Korea during the summer season. The data set was collected on eight different days with a 24 hour sampling period from July 27, 1995 through August 27, 1995. The chemical species measured were HNO{sub 3}, HNO{sub 2}, SO{sub 2} and NH{sub 3} in the gas phase and PM{sub 2.5} (d{sub p:}< 2- 2.5 {mu}m), SO{sup 2-}{sub 4}, NO{sub 3}{sup -} and NH{sub 4}{sup +} in the particulate phase. Outdoor air quality was of 4 major significant influence on the indoor environment during the summer season in Korea. Indoor concentrations for HNO{sub 3}, SO{sub 2}, PM{sub 2.5}, SO{sub 4} and NH{sup +}{sub 4} were significantly related to the corresponding outdoor concentrations.
