The concentrations of gas-phase and particle-bound polycyclic aromatic hydrocarbons (PAHs) were measured simultaneously at an industrial area (Taichung Industrial Park) and a suburban area (Tunghai University Campus) in Taichung, Taiwan. Twenty-four hours samplings for two consecutive days were performed between August and December 2002 at both sampling sites. Ambient air particle-bound PAHs were collected on quartz filters and gas-phase PAHs were collected on glass cartridges using a PUF Sampler, respectively. Both types of samples were extracted with a DCM/n-hexane mixture (50/50, v/v) for 24 h, then the extracts were subjected to gas chromatography-mass spectrometric (GC-MS) analysis. Total PAHs concentrations at the Taichung Industrial Park (TIP) sampling site and the Tunghai University Campus (THUC) sampling site were found to be 1232.3+/-963.6 and 609.8+/-356.3 ng/m(3), respectively. Stationary combustion processes were mainly responsible for PAHs sources at the TIP sampling site, while traffic vehicle exhaust was the largest contributor for PAHs sources at the THUC sampling site.
在台湾台中的一个工业区（台中工业园区）和一个郊区（东海大学校园）同时测量了气相和颗粒结合态多环芳烃（PAHs）的浓度。2002年8月至12月期间，在两个采样点连续进行了两天的24小时采样。环境空气中颗粒结合态PAHs分别用石英滤膜采集，气相PAHs用PUF采样器在玻璃滤筒上采集。两种类型的样品均用二氯甲烷/正己烷混合物（50/50，v/v）萃取24小时，然后将萃取物进行气相色谱 - 质谱（GC - MS）分析。台中工业园区（TIP）采样点和东海大学校园（THUC）采样点的总PAHs浓度分别为1232.3±963.6和609.8±356.3 ng/m³。固定燃烧过程是TIP采样点PAHs的主要来源，而交通车辆尾气是THUC采样点PAHs的最大贡献源。
