The polycyclic aromatic hydrocarbons (PAHs) and nitropolycyclic aromatic hydrocarbons (NPAHs) were determined by HPLC with fluorescence and chemiluminescence detections, respectively. The total concentration of six PAHs (pyrene, benz[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene and benzo[a]pyrene) decreased by the factor of 63.9% in the winter and 75.6% in the summer from 1999 to 2010. The total concentration of seven NPAHs (1,3-, 1,6-, 1,8-dinitropyrenes, 1-nitropyrene, 6-nitrochrysene, 7-nitrobenz[a]anthracene and 6-nitrobenzo[a]pyrene) significantly decreased by the factor of 88.0% in the winter and 89.2% in the summer during the same period. The concentration ratio of 1-nitropyrene to pyrene also significantly decreased in this period, suggesting a decrease in the emission amount. As the main reason for the significant decrease in the PAHs and NPAHs, the 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.47.1","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":"浜, 寛貴"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"徳田, 貴裕"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊崎, 陽彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大野, 友子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"渡辺, 有梨"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"神田, 哲雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"唐, 寧"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"亀田, 貴之"}],"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-1.pdf","filesize":[{"value":"574.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"OC-PR-HAYAKAWA-K-1.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/29386/files/OC-PR-HAYAKAWA-K-1.pdf"},"version_id":"3c7fab49-f44a-49e0-a20d-66a29a918811"}]},"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":"金沢市内における大気粉塵中多環芳香族炭化水素類およびニトロ多環芳香族炭化水素類の最近12年間の変遷","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"金沢市内における大気粉塵中多環芳香族炭化水素類およびニトロ多環芳香族炭化水素類の最近12年間の変遷"},{"subitem_title":"Variation in polycyclic aromatic hydrocarbons and nitropolycyclic aromatic hydrocarbons in airborne particulates collected in urban Kanazawa, Japan, in last 12 years","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":"29386","relation_version_is_last":true,"title":["金沢市内における大気粉塵中多環芳香族炭化水素類およびニトロ多環芳香族炭化水素類の最近12年間の変遷"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-27T20:36:26.279004+00:00"}
