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 <I>ΔE</I> 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 <I>ΔE</I> > ∼ 7.7 J.
