碩士 === 嘉南藥理科技大學 === 環境工程與科學系 === 100 === This study was depending on the perimeter of environmental air quality, PM2.5 and PM2.5-10 of PAHs of arising mobile and stationary pollution sources were sampling and 16 kinds of PAHs were analyzed by gas chromatography mass spectrometry (GC/MS). Monitoring sites were New Taipei City and Taoyuan County; the sampling sites were industrial areas, traffic intensive areas (transfer stations, roads, bus lanes, underground car parking, subways or tunnels) and outdoor area; this study would compared between the results and Environmental Protection Department monitoring stations (including Taoyuan, Da-yuan, Ping-zhen, Long-tan, Lu-zhu and Ban-qiao). The results show that PM2.5 at Taoyuan sampling site was range 0.58-7.04 ng/m3 and the average was 2.64 ng/m3 which that at the second of sampling time the highest total concentration of PAHs was obtained. PM2.5 concentration at New Taipei City sampling site was range 0.77-9.54 ng/m3 and the average was 2.33 ng/m3 which that at the third of sampling time, higher value of PM2.5 and PM2.5-10 concentration was observed. PM2.5 of PAHs of random sampling source was range 0.71-2.99 ng/m3 and the average was 1.27 ng/m3 which that the value was significantly lower than IND and DBA. About the industrial zone, PM2.5 of PAHs was range 0.19-4.13 ng/m3 and the average was 1.60 ng/m3 and the weather effected with the total PAHs concentration in Gui-shan and Tu-cheng by in winter was higher than summer PM2.5 of PAHs concentration in traffic intensive areas (roads) was range 4.38-18.3 ng/m3 and the average was 10.2 ng/m3. At the transfer station was range 1.39-42.3 ng/m3 and the average was 15.35 ng/m3, at the bus lanes was range 1.00-41.5 ng/m3 and the average was 15.2 ng/m3, underground car parking was range 5.33-15.8 ng/m3 and the average was 9.00 ng/m3, the subways or tunnels was range 11.9-18.2 ng/m3 and the average was 15.2 ng/m3 and tunnel sampling site was range 5.05-24.3 ng/m3. The highest average of total PAHs at traffic intensive areas was 14.5 ng/m3. About outdoor area, PM2.5 of total PAHs was range 0.47-1.62 ng/m3 and the average was 1.0 ng/m3. High carcinogenic potential of BbF+BaP+DBA concentration was range 0.01-0.74 ng/m3 and the average was 0.14 ng/m3.
