The quality of artificial substrate is an important factor for denitrification rate in a river bed sample. The denitrification rate per unit area in the river bed composed of concrete (13.8gN m⁻² year⁻¹) was higher than that in the gravel and sand (7.4gN m⁻² year⁻¹ ) river bed. The proportion of denitrificated nitrogen to the input nitrogen in the river was calculated. The average value for the concrete river bed was 0.3%, and 7.4% in the river bed of gravel and sand. From these results, if all area of Nogawa River was changed to a concrete bed, the proportion of denitrificatied nitrogen to input nitrogen is estimeted to be 1.7%, and about 3.1% in the case of a gravel and sand. Denitrification activity in the river bed of a small urban river was found to be dependent on the type of river bed.","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":"信州大学理学部付属諏訪臨湖実験所報告 7: 47-53(1991)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学理学部"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00089817","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":"Jong, Min, Oh","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ueda,  Shingo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ogura,  Norio","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":"Suwa07-06.pdf","filesize":[{"value":"385.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Suwa07-06.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/16439/files/Suwa07-06.pdf"},"version_id":"bd671e6a-e5df-40aa-bf56-b4f30ce63eac"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"denitrification","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"acetylene inhibition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"natural purification","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"attached microbial community","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Nogawa River","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":"MEASUREMENT OF DENITRIFICATION ACTIVITY OF THE BOTTOM SEDIMENT AT NOGAWA RIVER (Natural purification of an urban river ecosystem)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"MEASUREMENT OF DENITRIFICATION ACTIVITY OF THE BOTTOM SEDIMENT AT NOGAWA RIVER (Natural purification of an urban river ecosystem)","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1614"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-02-27"},"publish_date":"2009-02-27","publish_status":"0","recid":"16439","relation_version_is_last":true,"title":["MEASUREMENT OF DENITRIFICATION ACTIVITY OF THE BOTTOM SEDIMENT AT NOGAWA RIVER (Natural purification of an urban river ecosystem)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-09T02:01:26.076490+00:00"}
