Abstract
Air samples were collected at various altitudes (from 165 to 1153 m) to observe vertical distribution of
particulate PAHs concentrations using a very compact and light particle sampling package developed by Eun et
al.(2013). TD‐GC‐MS developed by Hwang et al.(2014) was applied to PAHs analysis for effective analysis of
PAHs contained trace amounts in the samples. The ranges of total PAHs concentrations were from 6.95 to 96.0 ng
m‐3 on the ground and from 3.75 to 21.74 ng m‐3 at high altitude, respectively. All of particulate PAHs
concentrations measured on the ground were higher than those measured at high altitude, while, the profile of
individual PAH compounds between the ground and high altitude samples were similar. It means the distribution
of particulate PAHs concentrations at high altitude were affected by the emission of PAHs emitted from ground.
