The polycyclic aromatic hydrocarbons (PAHs) and nitropolycyclic aromatic hydrocarbons (NPAHs) were determined by HPLC with fluorescence and chemiluminescence detections, respectively. The decreasing tendencies of the total concentrations of nine PAHs were observed at Noge and Kudan in the winter from 2006 to 2008. The decreasing tendencies of the total concentrations of three NPAHs were observed in both the summer and winter in Noge from 2006 to 2011. The decreasing tendencies of the NPAH concentrations were also observed in Kudan in the winter from 2006 to 2011 and in the summer from 2007 to 2009. The concentration ratio of 1-nitropyrene to pyrene also decreased in Noge and Kudan. As the main reason for the decrease in the urban atmospheric PAH and NPAH concentrations, the Japanese regulation of exhaust gas/particulates from automobiles was considered.","subitem_description_type":"Abstract"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"大気環境学会 = Japan Society for Atmospheric Environment"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.11298/taiki.50.117","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jsae-net.org/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/browse/taiki/-char/ja/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © Japan Society for Atmospheric Environment 大気環境学会"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN10512108","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1341-4178","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"鈴木, 元気"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森川, 多津子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"柏倉, 桐子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"唐, 寧"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"鳥羽, 陽"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"早川, 和一"}],"nameIdentifiers":[{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-05"}],"displaytype":"detail","filename":"OC-PR-HAYAKAWA-K-117.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"OC-PR-HAYAKAWA-K-117.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/29373/files/OC-PR-HAYAKAWA-K-117.pdf"},"version_id":"d27175ab-a1a4-4a47-9bca-7724c413f262"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"首都圏3地点における大気中PAH/NPAH濃度の長期変動","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"首都圏3地点における大気中PAH/NPAH濃度の長期変動"},{"subitem_title":"Variation of Polycyclic Aromatic Hydrocarbons and Nitropolycyclic Aromatic Hydrocarbons in Airborne Particulates Collected in Japanese Capital Area","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["1981"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-05"},"publish_date":"2017-10-05","publish_status":"0","recid":"29373","relation_version_is_last":true,"title":["首都圏3地点における大気中PAH/NPAH濃度の長期変動"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-27T20:36:34.290131+00:00"}
