Environmental transfer\nparameters such as sediment-water distribution coefficients (Kd) and concentration factors (CFs) for marine\norganisms are useful in mathematical models for the assessment. However, due to its low concentration in estuarine\nwater, Kd and CF data for U are scarce. Thus we studied a rapid method for separation and concentration of U from\nestuarine water samples using NOBIAS-CHELATE PA1 resin columns followed by inductively coupled plasma mass\nspectrometry (ICP-MS) for U measurement. Chemical recovery was about 100% at pH of 5.7 from the water\nsamples and alkali and alkaline earth metals were removed. The method was used to measure U concentrations in\nestuarine water samples collected at eight Japanese estuarine areas; they ranged from 0.1 to 3.8 ug/L. We also\nmeasured U concentrations in sediment and marine organism samples by ICP-MS after acid digestion. Using these\nvalues, we observed Kd (range: 39-284 L/kg) and CFs (0.86-52 L/kg for macroalgae, 0.087-15 L/kg for\ncrustaceans, and 0.52-93 L/kg for molluscs).","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"The Fifth International Symposium on Radiation Safety and Detection Technology (ISORD-5)","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Takata, Hyoe"}],"nameIdentifiers":[{"nameIdentifier":"685507","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Aono, Tatsuo"}],"nameIdentifiers":[{"nameIdentifier":"685508","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tagami, Keiko"}],"nameIdentifiers":[{"nameIdentifier":"685509","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uchida, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"685510","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高田 兵衛","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"685511","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"青野 辰雄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"685512","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上 恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"685513","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"685514","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Determination of naturally occurring uranium concentrations in seawater, sediment, and marine organisms in Japanese estuarine areas","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Determination of naturally occurring uranium concentrations in seawater, sediment, and marine organisms in Japanese estuarine areas"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-07-28"},"publish_date":"2009-07-28","publish_status":"0","recid":"69817","relation_version_is_last":true,"title":["Determination of naturally occurring uranium concentrations in seawater, sediment, and marine organisms in Japanese estuarine areas"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:10:05.178162+00:00"}
