中文摘要	本研究利用最先進的設備及技術進行了兩次道路旁、四次雪山隧道、一次新竹十八尖山、一TiO2粉體廠的周界及廠內各一次及一次溪頭森林的微粒採樣，採集的微粒包括PM10-2.5、PM2.5、PM0.18-0.1、PM0.1-0.056及PM0.056。除了分析微粒的濃度分佈，本研究亦分析微粒的化學成分，包括：有機碳、無機碳、水溶性離子及元素。學府路道路旁奈米微粒採樣的結果與Cass et al. (2000)在加州7個都會區做的實驗所得到的結果相近，奈米微粒的濃度約為1.5 mg/m3。雪山隧道的採樣及即時量測的結果顯示，奈米微粒的濃度在白天時高達20-40 mg/m3，凌晨降為5-15 mg/m3。台大溪頭實驗森林的PM0.1僅為0.99 mg/m3，且從即時微粒粒徑分佈的結果可研判溪頭森林明顯具自然奈米微粒產生源的特徵。TiO2粉體廠周界與廠內的奈米微粒濃度相近且不高，分別為8.1及9.4 mg/m3，可研判該廠奈米微粒的逸散情形很不明顯。微粒成分分析的結果顯示學府路及十八尖山微粒的成分以離子為主，前兩次雪山隧道(2008/11/15之前)則是以有機碳為主(汽油車為主)，後兩次的微粒成分以元素碳為主(柴油車為主)，可能是因為雪隧開放大客車通行及國內柴油車大幅增加，造成碳黑的排放量增加。溪頭森林的奈米微粒成分以離子為主，有機碳成分不高，僅佔總質量11.3 %，此值可能明顯低估。知識缺口部份，本研究已經回顧了十大主題，並已透過10場次座談會，參考專家學者的意見，除原本所詳列的技術面建議外，已增列可行的政策面、執行面等實質之具體建議，並納入在此期末總報告中，供執行EHS之相關部會參考。

摘要	Ambient particles (PM10-2.5、PM2.5、PM0.18-0.1、PM0.1-0.056及PM0.056) were studied at the road side of Poai Street and in the Eighteen-Peak mountain in Hsinchu, in the Syueshan high-way tunnel in Taipei, in the Experimental Forest of NTU in Nan-Tou and a TiO2 powder manufacturing factory in Kaohsiung, Taiwan, using a TSI model 3936 SMPS, two MOUDIs (MSP Model 110) and two Dichots (Thermo Scientific SA 241) in parallel. As well as particle size distribution, chemical compositions were analyzed by ICP-MS for elements, ion chromatograph for ions and Thermo-Optical Reflection (TOR) method for OC and EC. The road side sampling showed similar results with those of Cass et al. (2000) who measured the mass concentration of nanoparticles at seven urban areas in California. The average concentration of two road side sampling was 1.5 mg/m3. The high-way tunnel sampling and real-time measurement showed the concentration of nanoparticles at day time was 20-40 mg/m3 while it decreased to 5-15 mg/m3 at night time. Nanoparticle concentration of the NTU experimental forest was as low as 0.99 mg/m3 (MOUDI). Meanwhile from the real-time concentration distribution (SMPS) of nanoparticles, it is concluded that the NTU Experimental Forest is a specific biogenetic source of nanoparticles. Similar and low concentrations of nanoparticle were observed at the ambient and workplace of the TiO2 powder factory, indicating that nanoparticle emission was not severe. Chemical analysis showed ions were the most abundant species at the road side and the eighteen-peak mountain. The first two high-way tunnel samplings (before 2008/11/15) showed that OC was the most abundant component while the third and fourth tunnel samplings showed the most abundant species was EC. This was mainly due to the admission of bus driving in the tunnel from Nov. 15, 2008 and an substantial increase of diesel vehicles after that. Ions were the main component of nanoparticles in the forest, on the other hand the proportion of OC was only 11.3 %. This value indicates the OC might have been underestimated. This study also reviewed the latest papers about ten nanotechnolgy knowledge gaps, including the measurement methods of environmental nanoparticles, the protection instrument and equipment of manufactured nanomaterials, and developing the assessment methods of the toxicity of manufactured nanomaterials in water, etc. On the ten topics, ten seminars were held and the comments from the attending experts were collected. We summaried the suggestions in this report both on the technical and policy aspects of the nanotechnology knowledge gaps.
