The particle‐bound composition of polycyclic aromatic hydrocarbons (PAHs) associated with size distribution were measured for the ambient air of a bus station, an urban and a rural site with two MOUDIs and a NRI from April to September 1996 in Ping Tung area of Southern Taiwan. Twenty one individual PAH were analyzed primarily by using a gas chromatograph/ mass spectrometer (GC/MS). In the ambient air of bus station, the particle size distribution of particle‐bound total‐PAH composition was dominant in the submicron particles. In general, a smaller size particle has a higher total‐PAH composition. This is due to the fact that a smaller size of particle has a higher specific area and may therefore contain a greater amount of organic carbon which allows more PAH adsorption. These results showed that the values of total‐PAH composition in the fine particle mode (Dp < 1.0 μm) for bus‐station atmosphere averaged 2.2 and 9.0 times of magnitude higher than those measured in the urban and rural atmospher... |
