The long and continuous coastal line is the most precious natural resource of Kaohsiung, forming as it does the port culture and the unique expression of the river and the sea. Every day, cargo ships from around the globe bustle in and out of Kaohsiung Port. We has made a great effort to redevelop available space in order to cultivate a unique oceanic culture in Kaohsiung, such as, the docks and coastal scenic spots, can be developed. Furthermore, Kaohsiung clinched the opportunity to host the 2009 World Games. At that time, athletes, tourists, and the media will flock into the city and bring Kaohsiung into the global limelight. It's hard to define the beauty of Kaohsiung. There are so many extraordinary scenes in Kaohsiung such as Tzaishan, Lotus Lake, Chichin Island, The Hawaii of Kaohsiung and so forth. Just follow your heart and you will find Kaohsiung a fascinating city whether it's at the harbor or in downtown. The thriving and colorful scenery of the Love River and the romantic love boats are the most beautiful attraction for both the people of Kaohsiung and tourists. Kaohsiung, an industrial city, after winning over the right to host the eighth World Games in 2009, has been through from an "changing city" to a "healthy and exercise-friendly city." Under the emission reduction actions taken by the environment authorities, the unhealthy air quality days percentage (i.e., the air pollution standard index, PSI > 100) in Kaohsiung was 12% in 1998, descending annually to 7.34% in 2006. The monitoring station showed the same tendency especially for the main pollutant PM10 and O3,but we still need more stringent emission reduction actions to improve air quality. “2007 The 5th Asian Aerosol Conference” brings together researchers from many countries to sharing knowledge and experience and demonstrating innovative ways to improve air quality. I’m glad to welcome all the practitioners to visit Kaohsiung City, and enjoy the short stay in Ocean Capital of Taiwan. Chen Chu Kaohsiung City Mayor 3 高雄市長書面賀詞 高雄市位於台灣的南部，是台灣的第二大城，擁有陽光、海洋及優越港 灣條件是世界第六大貨櫃港，高雄市的地景、人文、建築、飲食與休閒，都與海 洋產生了密不可分的關係，高雄港的碼頭從哨船頭、哈瑪星、漁人碼頭、駁二藝 術特區、真愛碼頭到新光碼頭和主要的商業和遊憩地帶緊密銜接，營造出一條浪 漫的水岸，加上流域面積還蓋整個市區的愛河，沿著河畔的燈光與藝人的樂聲， 也成了高雄市最大的特色。 工業曾是高雄經濟發展的動脈，高雄市過去也長期面臨空氣品質改善的問 題， 2009 世界運動會為高雄的建設帶來國際性的視野，無論景觀地貌的改造、國 際地位的提升、低污染運輸系統的啟動，重新塑造高雄成為「海洋首都、清徹大 地」的都市。空品改善歷年已有重大的成果，空氣品質不良率由 1998 年的 12%到 2006 年的 7.34%改善幅度接近 40%，主要空氣汙染物濃度也大幅下降。 「2007 年第五屆亞洲氣膠研討會」來自各國的專家學者共同為空氣污染物質 的研究進行交流，高雄市政府環境保護局也藉著這個場合，展示歷年來空氣污染 管制的成果，也期望得到各位前瞻性的建言，藉由理論與實務的結合提升本市的 空氣品質。最後敬祝各位身體健康，精神愉快！竭誠的歡迎各位來到台灣的海洋 首都的高雄市。 高 雄 市 長 陳菊 謹致 4 Preface Aerosol science has progressed over the last few decades into increasingly wider areas of societal relevance. Starting with study of natural phenomena, it is now playing a pivotal role in the areas of environmental health, climate and materials technology. The interconnectedness of the environmental issues transcending national barriers has given truly a global dimension to the subject. These global concerns can only be addressed by joint international ventures and international organizations. The Asian Aerosol Conferences (AACs) held under the aegis of Asian Aerosol Research Assembly (AARA) constitute major efforts in this direction bringing together aerosol scientists from across the globe. Beginning with the first AAC in Nagoya, Japan in 1999, the successive AACs have grown in terms of the spectrum of international participation and the depth of the specialized topics covered under the conferences. In addition to the plenary lectures which review the current status of a particular area of aerosol specialization, it has become traditional to have special tutorial sessions as part of the conference technical programme. These have attracted several students and aerosol researchers and helped them to sharpen their base in the subject. Both modes of presentations, namely, the platform and the poster, have been used effectively by the conference attendees in putting across their ideas and methodologies. With strong foundations laid by the previous four conferences, the AAC-2007 being organized by CAART at Kaohsiung, Taiwan, promises to carry forward this tradition with greater vigor. At this juncture, I would specially like to remember Late Dr. Sheldon Friedlander who was a special keynote speaker at the 4thAAC-2005, held in Mumbai, India. It was a moment of great pride for delegates of AARA member associations to have interacted with him and witnessed his enthusiasm for aerosol science. I take this opportunity to thank the organizers of the AAC-2007 for putting their best efforts in leading this conference to a successful finale. This pre-proceedings volume, summing up the current scenario in aerosol research, is a proof of the success of their team work. I wish the delegates of the AAC-2007 a comfortable stay, stimulating technical deliberations and enriching experiences of the socio-cultural heritage of Taiwan. I wish the conference a big success. Y.S. Mayya President, AARA 5 Preface Hosted by the Chinese Association for Aerosol Research in Taiwan (CAART) under the auspices of the Asian Aerosol Research Assembly (AARA), the 5th Asian Aerosol Conference (AAC-2007) will be held in Kaohsiung, Taiwan on August 26-29, 2007. The AAC-2007 brings together the aerosol scientists working in the field of aerosol science and technology both here in Asia and around the world. The Conference aims to focus on the problems and resolutions of aerosol related issues of major concern in the world. It is hoped that this conference will provide valuable answers to many unresolved aerosol related questions through the discussion of research and technical papers among different research groups and individuals here in Taiwan and abroad. The Proceedings of AAC-2007 include 5 invited papers and 379 submitted abstracts arranged in 6 plenary sessions, 41 regular oral sessions, 5 special oral sessions, and 4 poster sessions. The conference program runs over three and half days, whereby the oral sessions are held with 5-6 sessions running in parallel. A total of 15 issues will be discussed during the Conference, including aerosol physics and chemistry, coarse and fine aerosols, Asian dust storm, PM in Asia, air pollution and atmospheric aerosols, aerosol sampling, aerosol measurement and instrumental analysis, global warming and atmospheric aerosols, nanoparticle synthesis and applications, indoor aerosols, bioaerosols, radioactive and nuclear aerosols, health effect of aerosols, environmental and health impact, and aerosol generation. Besides, there are two special symposiums devoted to PM Supersites and Atmospheric Observations and Advanced Measuring Techniques in the Remote Areas. Moreover, a one-day tutorial course including 3 topics is also arranged for young scientists and graduate students. I would like to express my sincere appreciation to the members of the Technical Program Committee and the Local Organization Committee, who were involved in reviewing the abstracts and organizing the Conference for their time and efforts. Special thanks also go to Prof. Wen-Jhy Lee (Co-Chair of AAC-2007), Prof. Yu-Chen Chang (Secretariat of AAC-2007), Prof. Long-Full Lin (Treasurer of AAC-2007), Prof. Chitsan Lin (Chair of Student Assistance Committee), Prof. Ying-I Tsai (Chair of Exhibits Committee), and Dr. Hsun-Yu Lin (AAC-2007 Assistant) for their great contribution to the Conference.
