Usually this water does not enter the body, but there have been cases where people have caught infectious diseases through inhalation of aerosols during bathing. In this study, as a model case of circulating bath, we examined the change in hygiene and chemical composition of the bathtub water in various conditions. To investigate the potential for bacterial growth in domestic bath water in Japan, changes in the concentrations of metal and non-metal inorganic compounds were studied as the number of days the water was re-used for increased. With re-use of bath water over 1 week, the concentrations of most of the compounds increased. However, the concentration of phosphorus decreased, and the concentrations of manganese and titanium showed both increases and decreases. Increasing concentrations could be attributed to sweat secreted from the skin of the bather, compounds eluted from the water heater as the bath water was re-heated, and dissolution of added bath salts. Consumption of inorganic compounds by bacteria and precipitation of metal hydr oxides could contribute to the decreasing concentrations. Common bacteria and coliform bacteria were measured simultaneously, and only the coliform bacteria increased in the water on the second day the water was used for bathing. Bacteria probably grew in the pipes between the water heater and the bat htub.\n","subitem_description_type":"Abstract"},{"subitem_description":"入浴は，身体を温めたり，石鹸などの成分を皮膚から取り除くために行われる。通常，浴槽水は体内に入ることはないが，入浴中のエアロゾルの経気道的吸入により，感染症を引き起こすことが知られている。本研究では，循環型風呂のモデルとして，衛生学的に浴槽水の成分が様々な使用条件でどう変化するかを調べた。日本における家庭用浴槽水中での微生物繁殖の可能性を調べるため，金属，非金属無機化合物の日ごとの濃度変化を追跡した。浴槽水の再利用を1 週間行ったところ，多くの化合物濃度は増加した。リンのみが減少し，マンガンやチタンは増加と減少の両方が観察された。これらの変化において，増加は入浴者の皮膚から排泄された汗，風呂釜からの溶出，入浴剤からの混入が考えられた。減少は浴槽水中細菌による消費と金属水酸化物の沈殿析出が考えられた。同時に一般細菌や大腸菌群についても測定したが，大腸菌は入浴2 日目に増加し，風呂釜中に生育場所がある可能性が示唆された。","subitem_description_type":"Abstract"}]},"item_10002_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"105","nameIdentifierScheme":"WEKO"}],"names":[{"name":"小林, 淳"}]},{"nameIdentifiers":[{"nameIdentifier":"106","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000090453597","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}],"names":[{"name":"池田, 啓一"}]},{"nameIdentifiers":[{"nameIdentifier":"139","nameIdentifierScheme":"WEKO"}],"names":[{"name":"杉山, 英男"}]}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18827314","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小林, 淳"}],"nameIdentifiers":[{"nameIdentifier":"105","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"池田, 啓一"}],"nameIdentifiers":[{"nameIdentifier":"106","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000090453597","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]},{"creatorNames":[{"creatorName":"杉山, 英男"}],"nameIdentifiers":[{"nameIdentifier":"139","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":"2016-06-10"}],"displaytype":"simple","filename":"小林　淳_1.pdf","filesize":[{"value":"2.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PDF","url":"https://nvlu.repo.nii.ac.jp/record/100/files/小林　淳_1.pdf"},"version_id":"65b35df5-08b1-4d9d-b0e7-c4ab494fca0c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"bathing","subitem_subject_scheme":"Other"},{"subitem_subject":"coliform group","subitem_subject_scheme":"Other"},{"subitem_subject":"inorganic compound","subitem_subject_scheme":"Other"},{"subitem_subject":"入浴","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"大腸菌群","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"無機化合物","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":"Changes in the Concentrations of Inorganic Compounds in Domestic Bath Water in Japan with Re-use of the Water","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Changes in the Concentrations of Inorganic Compounds in Domestic Bath Water in Japan with Re-use of the Water"}]},"item_type_id":"10002","owner":"14","path":["21"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-06-10"},"publish_date":"2016-06-10","publish_status":"0","recid":"100","relation_version_is_last":true,"title":["Changes in the Concentrations of Inorganic Compounds in Domestic Bath Water in Japan with Re-use of the Water"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2023-06-19T09:10:24.719622+00:00"}
