Polycyclic aromatic hydrocarbon (PAHs) of 19 substances were determined by using the pressorized liquid extraction (PLE) method and GC-Ms to investigate the behavior of FAHs. New collection method of combining Quartz fiber filter paper (QFP), Emu-C18 disk (C18) and Active carbon fiber filter paper (ACEP) was employed for collecting atmospheric Pans in this work. The following matters have been mainly clarified from this work. (1) The atmospheric PAHs having more than 5 rings were corrected by QFP for 89. 8～100 %, the Pans having 4 rings were collected by C18 for 58.0～72. 3 %, and the FAHs having 3 rings were by ACFP for 41.6～73.6 % (though low recovery of FAHs having 3 tings in winter). (2) The annual average concentration of FAHs is 21 ng/m^3 at the urban region and 9. 9 ng/m^3 at the mountains area, In winter and spring, similar  concentration level of total PAHs were found between at the urban region and at the mountains area. On the other hand, in summer and autumn, the concentration of total PAHs at the urban region is 4～6 times larger than that at the mountains. area. (3) PAHs amounts in precipitation increased in winter at the mountains area. (4) The PAHs composition ratio in precipitation showed two composition patterns (i. e. in case of (I) summer and autumn, (II) winter and spring) at 2 sites in Niigata Prefecture. (5) Both the concentrations of PAHs in air and those in precipitation increased in winter, but no clear correlation was observed between them by correlation analysis.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "39432", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Oura, Kousuke"}]}, {"nameIdentifiers": [{"nameIdentifier": "39433", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Murayama, Hitoshi"}]}, {"nameIdentifiers": [{"nameIdentifier": "39434", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Yagoh, Hiroaki"}]}, {"nameIdentifiers": [{"nameIdentifier": "39435", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kano, Naoki"}]}, {"nameIdentifiers": [{"nameIdentifier": "39436", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Imaizumi, Hiroshi"}]}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "日本環境化学会"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN10547099", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "09172408", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "大浦, 孝祐"}], "nameIdentifiers": [{"nameIdentifier": "39427", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "村山, 等"}], "nameIdentifiers": [{"nameIdentifier": "39428", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "家合, 浩明"}], "nameIdentifiers": [{"nameIdentifier": "39429", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "狩野, 直樹"}], "nameIdentifiers": [{"nameIdentifier": "39430", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "今泉, 洋"}], "nameIdentifiers": [{"nameIdentifier": "39431", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-30"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "17_2_205-216.pdf", "filesize": [{"value": "1.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1300000.0, "url": {"label": "17_2_205-216.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2857/files/17_2_205-216.pdf"}, "version_id": "0873c70c-1f69-41d9-8443-933bedea9eed"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Polycyclic aromatic hydrocarbon (PAHs)", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Atmospheric and precipitation samples", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Niigata Prefecture", "subitem_subject_scheme": "Other"}, {"subitem_subject": "GC-MS", "subitem_subject_scheme": "Other"}]}, "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": "大気・降水中に含まれる多環芳香族炭化水素類(PAHs)の測定とその挙動", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "大気・降水中に含まれる多環芳香族炭化水素類(PAHs)の測定とその挙動"}, {"subitem_title": "大気・降水中に含まれる多環芳香族炭化水素類(PAHs)の測定とその挙動", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/21905", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-04-18"}, "publish_date": "2013-04-18", "publish_status": "0", "recid": "2857", "relation": {}, "relation_version_is_last": true, "title": ["大気・降水中に含まれる多環芳香族炭化水素類(PAHs)の測定とその挙動"], "weko_shared_id": null}
