The water quality of Kitakata Lake has been chronically eutrophic. Over the last 20 years, Chemical Oxygen Demand (COD), Total Nitrogen (T-N) and Total Phosphorus (T-P) concentrations have remained on the same level, which violate the water quality standard imposed to the lake (classified as the type B and IV). The seasonal variation has shown that, in summer, pH, COD and T-P increase whereas Dissolved Oxygen (DO) and T-N decrease, which may be typical for eutrophic lakes. The analysis of incoming loads to the lake revealed that approximately 60% of COD, T-N and T-P originates from non-point sources like rice field, farm and forest, indicating the importance of measures against those sources.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.57375/00000481","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"福井工業大学"}]},"item_10002_relation_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"TF00008940","subitem_relation_type_select":"NCID"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2868571","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"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":"高島, 正信"}],"nameIdentifiers":[{"nameIdentifier":"10134","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takashima, Masanobu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"10135","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":"2023-04-12"}],"displaytype":"detail","filename":"KJ00004766989.pdf","filesize":[{"value":"589.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004766989.pdf","url":"https://fut.repo.nii.ac.jp/record/487/files/KJ00004766989.pdf"},"version_id":"543c3b0c-0dae-4901-9adf-5edab2ab0e61"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"北潟湖の水質改善に関する調査研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"北潟湖の水質改善に関する調査研究"},{"subitem_title":"Study for water quality improvement in Kitakata Lake","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"2","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-04-04"},"publish_date":"2009-04-04","publish_status":"0","recid":"487","relation_version_is_last":true,"title":["北潟湖の水質改善に関する調査研究"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-06-20T14:31:27.223617+00:00"}
