Mimic pbotodegradation experiments on DOM in Lake Biwa showed that solar irradiation caused a decreaseinthe both UV and fluorescence intenslty. The decreaslng trends of the ratio between peak area of peak2　and peak3 With photodegradtion process indicated that large photo sensitive molecules are fragmented into small molecules dming photodegradation, The flrStl0rder reaction kinetics was applied toanalyze the photodegradation of DOM. Two-step photodegradation was suggested forthefluorescent DOM with different rate constant values, Results obtained in the present study suggested that fluorescent DOM is susceptible to photodegradation and fragmented to relatively smaller size molecllles with the progress of photodegradation,","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学山地水環境教育研究センター研究報告 6: 29-34(2010)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学山地水環境教育研究センター"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1348-7612","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11887942","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"attribute_name":"出版タイプ","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":"Tareq,  Shafi M","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Maruo,  Masahiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nagahuchi,  Osamu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ohta,  Keiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"Inlandwater06-008.pdf","filesize":[{"value":"322.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Inlandwater06-008.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/16317/files/Inlandwater06-008.pdf"},"version_id":"b062ee60-587f-497e-b8a5-59ed64a3f5c3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Humic substance","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"HPSEC","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Lake Biwa","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Biogeochemistry","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Molecular changes in dissolved organic matter during photodegradation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Molecular changes in dissolved organic matter during photodegradation","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1602"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-07-21"},"publish_date":"2010-07-21","publish_status":"0","recid":"16317","relation_version_is_last":true,"title":["Molecular changes in dissolved organic matter during photodegradation"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-09T01:43:53.492208+00:00"}
