Decomposition characteristics of fifteen different poly-cyclic aromatic hydrocarbons (PAHs) in the ambient particles by soft X-rays were experimentally investigated by irradiating the soft X-rays onto ambient particulates collected on silica fibrous filters. Influences of irradiating duration, distance between a soft X-ray tube and filter sample and energy of soft X-rays on the decomposed fraction of PAHs were discussed. Properties of PAHs such as boiling temperature and molecular band gap energy ΔE were related to the decomposed fraction of each PAH.<BR>PAHs with 2-6 aromatic rings were decomposed by the soft X-ray irradiation but a maximum decomposed fraction was found to exist. The maximum decomposed fraction and decomposing rate constant increased with the irradiation energy of soft X-rays. The maximum decomposed fraction seems to decrease for PAHs with 4-aromatic rings such as Chrysene and increase for ΔE > ∼ 7.7 J.
