Abstract
The distribution of PM10 was investigated using its measurement data collected from a total of 152 AQM stations located across South Korea from 1998 to 2003. It was found that PM10 concentration reaches its peak in the springtime due to massive wind-blown dusts during the Asian Dust (AD) period. Then the concentration level decreases in the summertime, after the rain shower season. When the PM10 data sets were compared across different cities, their patterns contrasted sharply. The highest PM10 concentration was measured in Seoul $(68.2{\mu}g/m^3)$, while the lowest PM10 concentration was measured in Jeju $(39.2{\mu}g/m^3)$. The results of our analysis indicate that PM10 concentrations exhibit a strong proportional relationship with respect to the size of the city. With respect to the correlation analysis of our results, it was evident that PM10 concentrations of nearby cities were found to affect each other.
