摘要:	本研究是以北部環境之周界空氣品質、移動性污染源及固定性污染源所產生之PM2.5及PM2.5-10之PAHs進行採樣與分析，十六種PAHs以氣相層析質譜儀(GC/MS)分析，在新北市及桃園縣部分採樣地點選擇為: 周界空氣(同步採樣點、工業區)、交通密集區(各大轉運站、一般道路、公車專用道、地下停車場、地下道、隧道)及光化採樣點；桃園縣則為環保署一般人工空氣品質監測站(包含桃園、大園、平鎮、龍潭、蘆竹、板橋)。研究結果顯示，在桃園人工測站之PM2.5總PAHs濃度介於0.58~7.04 ng/m3之間，平均值為2.64 ng/m3，其中第二季總PAHs濃度為最高。縣市同步採樣PM2.5之總PAHs濃度介於0.77~9.54 ng/m3之間，平均值為2.33 ng/m3，在第三季PM2.5及PM2.5-10明顯與其他季高出許多。污染物傳遞採樣PM2.5之總PAHs濃度介於0.71~2.99 ng/m3之間，平均值為1.27 ng/m3，在第二季中IND及DBA濃度含量明顯偏高。工業區採樣PM2.5中之總PAHs濃度介於0.19~4.13 ng/m3之間，平均值為1.60 ng/m3，在龜山及土城各採樣點顯示第二季總PAHs濃度大於第一季。在交通密集區之一般道路採樣之總PAHs濃度介於4.38~18.3 ng/m3之間，平均值為10.2 ng/m3；轉運站PM2.5之總PAHs濃度介於1.39~42.3 ng/m3之間，平均值為15.35 ng/m3；公車專用道PM2.5之總PAHs濃度介於1.00~41.5 ng/m3之間，平均值為15.2 ng/m3；地下停車場之PM2.5總PAHs濃度介於5.33~15.8 ng/m3之間，平均值為9.00 ng/m3；隧道之PM2.5總PAHs濃度介於11.9~18.2 ng/m3之間，平均值為15.2 ng/m3。汽機車地下道PM2.5之總PAHs濃度介於5.05~24.3 ng/m3之間，平均值為14.5 ng/m3，在交通密集區之轉運站所測得之總PAHs為最高。光化學採樣PM2.5之總PAHs濃度介於0.47~1.62 ng/m3之間，平均值為1.00 ng/m3，具高致癌潛能之BbF+BaP+DBA，平均濃度範圍為0.01~0.74 ng/m3，平均濃度為0.14 ng/m3，在光化學採樣中，由於陽光照射之下，與周界空氣及交通密集區採樣之濃度有明顯之差異。 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.
