Abstract
In this study, the characteristics of $\small{PM_{2.5}}$ and $\small{PM_{2.5-10}}$ concentrations were identified in two different functional areas including Chuncheon and Youngwol, Korea. Even though the anthropogenic emission rates of $\small{PM_{2.5}}$ and $\small{PM_{10}}$ are approximately four times higher in Youngwol than in Chuncheon their atmospheric concentrations were statistically higher in Chuncheon. In Chuncheon, both $\small{PM_{2.5}}$ concentrations and the ratio of $\small{PM_{2.5}/PM_{10}}$ increased as relative humidity (RH) increased possibly because the inorganic and/or organic secondary aerosols were actively formed at high RH. This result was also supported by that $\small{PM_{2.5}}$ concentration was enhanced under the fog and mist conditions in Chuncheon. On the other hand, both $\small{PM_{2.5}}$ and $\small{PM_{2.5-10}}$ concentrations clearly increased with the southerly winds blown from the cement production facility in Youngwol. In addition, high $\small{PM_{2.5-10}}$ concentrations were observed with high wind speed, low relative humidity, and high $\small{NO_2}$ concentrations in Youngwol, suggesting that $\small{PM_{2.5-10}}$ was generated through the physical process including crushing and packing procedures followed by resuspension from cement and lime factory.
