This research was aimed at the central region of Taiwan, to explore the PM2.5 and the corresponding relationship between air pollutants. To avoid thediscrepancy between the terrain and the meteorological conditions, we select the only industrial testing station called Xianxi station, also chose the other two general stations which stands in the same county, Changhua station and Erlin station. Analyzed the statistics gathered from 2013 to2015,using SPSS to analyzed the data in order to understand the correlation between the change of air pollutants and the concentration of particles matter. Erlin station shows that all the air pollutants have high related to PM2.5, and there is a clear regression relationship. Changhua station shows the same result except for the NOX and THC shows negative correlation. Xianxi industrial testing station indicated that only NMHC shows negative correlation with PM2.5 According to the research, the main sources of PM2.5 in the Changhua station and Xianxi industrial testing station might be the activity of the mobile vehicles; as to the main sources of PM2.5 in the Erlin station might be caused by construction or raise dust.
