Abstract

The most pivotal approach to improve subway indoor air quality (IAQ) is to examine the emission sources and particulate behavior. Therefore, the main objec-tive of this study is to investigate the particulate be-havior in the subway. In order to examine IAQ in the subway, a sampling and measurement campaign was carried out for 35 sites during the summer and winter seasons from May, 2005 to February, 2006. In case of 24 hour measurement, the mean concen-trations (PM₁₀-24 hr) of platform and waiting room were 156.18±53.79 μg/m³ and 111.00±53.31 μg/ m³. Besides, as a result of 20 hour measurement, the mean concentrations (PM₁₀-20 hr) of platform and waiting room were 146.09±53.71 μg/m³ and 99.08±42.77 μg/m³, respectively. In general, PM₁₀-24 hr was higher than PM₁₀-20 hr, and both PM con-centrations showed a high correlation coefficient (r== 0.803). It was found that the PM_2.5 concentration (109.56±28.24 μg/m³) in winter was higher than that (83.66±57.82 μg/m³) in summer.
