The purpose of this study was to investigate the characteristics of air quality using data from which obtain local air quality monitoring system for cohort study in Chungju, Korea. We analyzed the concentration data of , and in Chungju and industrial cities in 2006. We compared a industrial area with a cohort study area using by bicluster algorithm. In the case of , the rate of the cluster time was and the cluster time number of two areas was similar. In the case of and , the number of cluster time between a industrial area and cohort study area was clearly different.
