Therefore,239Pu and 237Np are important radionuclides in the safety assessment related to geological disposal of radioactive waste because of the possibility of long-term exposure to humans. Mobilities of these radionuclides in the environment are of interest, therefore, in this study, for the first time, soil-soil solution distribution coefficient (Kd, L/kg) was determined using global fallout 239Pu and 237Np in soil. The Kd values were determined by extracting these radionuclides from 23 soil samples using a laboratory batch method. The desorption Kd values of 239Pu are found to vary from 3.2×103 to 1.4×105 L/kg, and its geometric mean (GM) and arithmetic mean (AM) are 2.3×104 L/kg and 3.2×104 L/kg, respectively. The desorption Kd values of 237Np range from 8.9×102 to 2.1×104 L/kg, and its GM and AM are 4.1×103 L/kg and 6.4×103 L/kg, respectively. A comparison between the obtained Kd of 239Pu and 237Np indicated that 239Pu Kd were about 6-fold higher than 237Np in Japanese paddy field soils. Pearson’s correlation analysis suggested that the main factors contributing to the sorption/desorption of Pu isotopes in Japanese paddy soils were related to the amounts of Fe and Mn oxides, while the sorption/desorption of 237Np in Japanese paddy soils would be controlled by an ion-exchange reaction, and/or complex-formation with organic matter, especially in Fluvisols.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.chemosphere.2021.132775","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0045-6535","subitem_source_identifier_type":"ISSN"}]},"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":"Zheng, Jian"}],"nameIdentifiers":[{"nameIdentifier":"1040969","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Keiko, Tagami"}],"nameIdentifiers":[{"nameIdentifier":"1040970","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shigeo, Uchida"}],"nameIdentifiers":[{"nameIdentifier":"1040971","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shibutani, Sanae"}],"nameIdentifiers":[{"nameIdentifier":"1040972","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishida, Keisuke"}],"nameIdentifiers":[{"nameIdentifier":"1040973","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hamamoto, Takafumi"}],"nameIdentifiers":[{"nameIdentifier":"1040974","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zheng, Jian","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1040975","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Keiko, Tagami","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1040976","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shigeo, Uchida","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1040977","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Soil-soil solution distribution coefficients of global fallout 239Pu and 237Np  in Japanese paddy soils","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Soil-soil solution distribution coefficients of global fallout 239Pu and 237Np  in Japanese paddy soils"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-08-23"},"publish_date":"2021-08-23","publish_status":"0","recid":"84965","relation_version_is_last":true,"title":["Soil-soil solution distribution coefficients of global fallout 239Pu and 237Np  in Japanese paddy soils"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T17:24:12.120830+00:00"}
