The purpose of this study is to understand the impact that temperature and relative humidity have on the volatilization loss of particulate nitrate $(NO_3^-)$ from Teflon filters during measurements of ambient fine particles $(PM_{2.5})$. Fine particles $(d_p<2.5{\mu}m)$ were measured using an annular denuder system (ADS) at four representive areas in Seoul. The measurements were made during 28 different days at 24-hr sampling intervals from February 14 to October 15, 1997. In this study, nitrate losses. calculated by the ratio of nitrate on the nylon filter to their sum in both Teflon and nylon titters, varied seasonally in the following order: summer (45.5%) > spring (23.8%) > fall (20.6%) > winter (19.7%). The results showed strong correlations with temperature, but we did not observe any significant effects of relative humidity. However, we observed that both temperature and relative humidity influenced the ambient gas/particle nitrate ratio in a different case study using a denuder.
