We investigated pollutants from rivers and their main sources. Inflow BOD concentrations from rivers, a septage treatment facility, and a sewage treatment facility were stable and lower than water quality standards under the Water Pollution Prevention Law and environmental quality standards. Therefore, the high COD concentration in Kuji Bay was not explained by the direct inflow of organic matter. However, results revealed a high load of nitrogen from a septage treatment facility, and phosphorus from a sewage treatment facility. Phosphorus concentration was extremely high in the Tamanowaki River : the concentration recorded in February was 10 times higher than that during normal periods, indicating an upstream source. The COD concentration of Kuji Bay, which was in excess of environmental standards, was suggested to the reproduction of organic matter by phytoplankton in the water using terrigenous nitrogen and phosphorus, rather than the direct inflow of terrestrial organic pollutants. The rate of water flow blockage is expected to increase because of breakwater construction at the bay mouth. Point source measurements are expected to show great improvement, but nitrogen and phosphorus loads should be continuously studied.","subitem_description_type":"Other"}]},"item_7_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"6","subitem_description_type":"Other"}]},"item_7_description_16":{"attribute_name":"アクセション番号","attribute_value_mlt":[{"subitem_description":"KJ00009755239","subitem_description_type":"Other"}]},"item_7_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_7_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_7_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11348438","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13446347","subitem_source_identifier_type":"ISSN"}]},"item_7_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"岩手県立大学総合政策学部"},{"subitem_text_value":"久慈市総合政策部政策推進課"},{"subitem_text_value":"岩手県県北広域振興局保健福祉環境部"},{"subitem_text_value":"岩手県県北広域振興局保健福祉環境部"},{"subitem_text_value":"岩手県県北広域振興局保健福祉環境部"},{"subitem_text_value":"岩手県県北広域振興局保健福祉環境部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"辻,
