Abstract PAHs have been considered as one of Persistent Organic Pollutants (POPs) in the world because of their toxic, persistent and semi-volatile properties. Therefore, the Ministry of Environment in Korea has monitored PAH compounds in the atmosphere since 2003 in order to evaluate temporal and spatial distributions and to assess the impact of PAHs concentrations to the human health. In this study, we will statistically analyze PAH time trend data from the thirty one sampling sites (Toxic Air Pollutants Monitoring Stations) which consist of various urban and rural sites in Korea and show the characteristics of the temporal and spatial trends of atmospheric concentrations of PAHs in Korea. Also, based on the measured data, toxicity equivalency factors (TEFs) and mutagenic equivalency factors (MEQs) of PAHs will be produced and the major factor determining high TEFs and MEQs values will be discussed.
