Potential effects of atmospheric aerosols vary according to their chemical composition, diameter and mixing states. In order to investigate the different aerosol sources and their effect on aerosol chemical composition, the variation of atmospheric aerosol was measured with an Aerosol Mass Spectrometer (AMS) at a suburban area in winter. Three trends were observed, under high NO, Ox concentrations and under high WS. When comparing those three variables with gaseous NO and Ox, particulate nitrate, oxygenated organic aerosol (OOA), and hydrocarbon-like organic aerosol (HOA) and with wind speed and direction. High peaks on the m/z 43, 57 corresponded to high NO levels, as a result of increments in the emission from fuel combustion. Meanwhile, a decrease on those peaks corresponded to high Ox levels, on periods with higher photochemical oxidation activity. However, the aerosol size distribution on both, high NO and high Ox levels were similar, indicating that emissions from combustion under high NO periods do not affect the size distribution directly. The results of back trajectory analyses under high WS conditions suggest that high OOA and sulphate levels are brought by air masses from continental China.","subitem_description_type":"Abstract"}]},"item_113_description_25":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"指導教員: 埼玉大学大学院理工学研究科教授 坂本和彦","subitem_description_type":"Other"}]},"item_113_description_33":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_113_description_34":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_113_other_language_26":{"attribute_name":"その他の言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_113_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"埼玉大学大学院理工学研究科"}]},"item_113_record_name_8":{"attribute_name":"書誌","attribute_value_mlt":[{"subitem_record_name":"平成19年度環境制御システムコース修士論文発表会要旨集"}]},"item_113_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"KUBOTA, Tsutomu"}]},"item_113_text_36":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"GM0000008"}]},"item_113_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学大学院理工学研究科環境制御システムコース循環システム講座循環制御研究室"}]},"item_113_text_5":{"attribute_name":"著者 所属（別言語）","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"窪田, 勉"},{"creatorName":"クボタ, ツトム","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-23"}],"displaytype":"detail","filename":"GM0000008.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"GM0000008.pdf","url":"https://sucra.repo.nii.ac.jp/record/10475/files/GM0000008.pdf"},"version_id":"bdfe64f2-74ac-41f3-be69-2e95c8b5e675"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Aerosol Mass Spectrometer","subitem_subject_scheme":"Other"},{"subitem_subject":"suburban area","subitem_subject_scheme":"Other"},{"subitem_subject":"primary and secondary aerosol","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"エアロゾル質量分析計を用いた大気中微小粒子の挙動調査","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"エアロゾル質量分析計を用いた大気中微小粒子の挙動調査"}]},"item_type_id":"113","owner":"3","path":["434"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-03-07"},"publish_date":"2008-03-07","publish_status":"0","recid":"10475","relation_version_is_last":true,"title":["エアロゾル質量分析計を用いた大気中微小粒子の挙動調査"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-15T18:49:43.953888+00:00"}
