We investigated these factors in Omura Bay from May 2008 to May 2010, in order to clarify the relationship between them. Samples were collected from four depths(0, 2, 6, and 10 m)at five sites. The COD values ranged from 0.68 to 3.94 mg/L with a mean value of 1.95 mg/L, while the TOC values ranged from 0.811 to 2.170 mg/L with a mean value of 1.345 mg/L. Although half of the samples showed high COD values(>2.0 mg/L), most of the samples showed low TOC values(<2.0 mg/L). The samples from the upper layer showed higher COD and TOC values than the samples from the middle or bottom layers. A significant positive correlation between the COD and TOC values was obtained(0.604); furthermore, a strong correlation between these parameters was observed for the samples obtained from the inner bay. These results suggest that measuring TOC may be useful for estimating the degree of pollution in enclosed coastal sea areas.","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"抄録","attribute_value_mlt":[{"subitem_description":"化学的酸素要求量(COD)と全有機炭素量(TOC)を測定することにより､大村湾における有機汚濁ﾚﾍﾞﾙを評価した｡本研究では､2008年5月から2010年5月にかけ､水深別(0､2､6､10m)に5地点(湾口部､湾央部､湾奥部3地点)より採水し､両者を測定した｡その結果､COD は 0.68～3.94mg/L(平均 1.95mg/L)､TOC は 0.811～2.170mg/L(平均 1.345mg/L)となり､COD では試料の約半数が環境基準の 2mg/L 以上を示したのに対し､TOC ではほぼ全試料で 2mg/L 以下となり､COD と比べて低値を示した｡両者とも表層で高く､深度とともに低い傾向を示した｡Pearson の積率相関分析を行った結果､両者の間には正の相関がみられた(相関係数:0.604)｡また､海水交換が十分でないと示唆される湾奥部ほど､両者の相関性が高くなる傾向がみられた｡以上の結果より､閉鎖性海域ほど両者の相関性が高く､TOC の測定は水質汚濁を把握するには有効であることが示唆された｡"}]},"item_10_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎国際大学"}]},"item_10_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11766493"}]},"item_10_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-4094"}]},"item_10_subject_25":{"attribute_name":"Keyword","attribute_value_mlt":[{"subitem_subject":"chemical oxygen demand, total organic carbon, correlation, Omura Bay","subitem_subject_scheme":"Other"}]},"item_10_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"出口, 雄也"},{"creatorName":"ﾃﾞｸﾞﾁ, ﾕｳﾔ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"岸, 智裕"},{"creatorName":"ｷｼ, ﾄﾓﾋﾛ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長岡(浜野), 恵"},{"creatorName":"ﾅｶﾞｵｶ(ﾊﾏﾉ), ﾒｸﾞﾐ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小野寺, 祐夫"},{"creatorName":"ｵﾉﾃﾞﾗ, ｽｹｵ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長岡, 寛明"},{"creatorName":"ﾅｶﾞｵｶ, ﾋﾛｱｷ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-05-14"}],"displaytype":"detail","filename":"RN12-017.pdf","filesize":[{"value":"287.0 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"RN12-017","url":"https://niu.repo.nii.ac.jp/record/837/files/RN12-017.pdf"},"version_id":"6b10b943-ea46-46a1-bca4-bddea8d1a176"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"化学的酸素要求量"},{"subitem_subject":"全有機炭素"},{"subitem_subject":"相関"},{"subitem_subject":"大村湾"}]},"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"}]},"item_title":"大村湾海水における過ﾏﾝｶﾞﾝ酸ｶﾘｳﾑ消費量と全有機炭素の比較検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"大村湾海水における過ﾏﾝｶﾞﾝ酸ｶﾘｳﾑ消費量と全有機炭素の比較検討"},{"subitem_title":"Comparative Study of Chemical Oxygen Demand and Total Organic Carbon in Omura Bay","subitem_title_language":"en"}]},"item_type_id":"10","owner":"3","path":["23"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-04-01"},"publish_date":"2015-04-01","publish_status":"0","recid":"837","relation_version_is_last":true,"title":["大村湾海水における過ﾏﾝｶﾞﾝ酸ｶﾘｳﾑ消費量と全有機炭素の比較検討"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-21T06:15:28.059719+00:00"}
