We developed a sampler for collecting atmospheric polycyclic aromatic hydrocarbons (PAHs) and nitropolycyclic (NPAHs) by attaching glass column packed with XAD-4 resin to the gas sampling port of high-volume air equipped filter. When upper bottom layers were 64 g 32 resin, respectively, all PAHs NPAHs in phase quantitatively collected without any break through, while particle on samples at suburban downtown Kanazawa using proposed sampler. It was found that about 95% 2-3 ring more than 99% 2-ring existed chiefly phase, 4-ring such as fluoranthene (FR) pyrene (Pyr) 3-ring both phases other having 4-rings or except FR Pyr almost completely phase. Our data also indicated adsorption atmosphere is controlled same mechanism PAHs.
