On average, the nominal water soluble and exchangeable Pu fractions in upland soils were 0.07% and 0.02%, respectively, while those fractions in the rice paddy soils were 0.10% and 0.03%, respectively. Sequential extraction results indicated that the dominant sinks of Pu in both upland and paddy soils were the immobile organic matter fraction, Fe-Mn oxides and the residual fraction. Both the water soluble and NH4OAc exchangeable Pu percentages showed a significant negative correlation with the exchangeable Ca2+ concentration in the soils. Regarding the potential plant bioavailability of Pu, a significant correlation (r=0.55, p<0.05) was observed between the Pu concentration in rice and the water-soluble Pu concentration in the corresponding rice paddy soils, and that illustrated the water-soluble Pu fraction was likely to be available for rice plant uptake. This bioavailable fraction was further applied in evaluating the available transfer factor (ATF) of Pu by dividing the Pu concentration in rice with the bioavailable Pu concentration in the soil. We consider the ATF to be more representative to illustrate the transfer ability of Pu from soil to rice plant.","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":"日本放射化学会65回討論会","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":"Ni, Youyi"}],"nameIdentifiers":[{"nameIdentifier":"1003314","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zheng, Jian"}],"nameIdentifiers":[{"nameIdentifier":"1003315","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Guo, Qiuju"}],"nameIdentifiers":[{"nameIdentifier":"1003316","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Huang, Zhaoya"}],"nameIdentifiers":[{"nameIdentifier":"1003317","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Keiko, Tagami"}],"nameIdentifiers":[{"nameIdentifier":"1003318","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shigeo, Uchida"}],"nameIdentifiers":[{"nameIdentifier":"1003319","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zheng, Jian","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1003320","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Keiko, Tagami","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1003321","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shigeo, Uchida","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1003322","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":"Extractability of Pu from agricultural soils and its indication of bioavailability","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Extractability of Pu from agricultural soils and its indication of bioavailability"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-07-26"},"publish_date":"2021-07-26","publish_status":"0","recid":"83410","relation_version_is_last":true,"title":["Extractability of Pu from agricultural soils and its indication of bioavailability"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:30:41.699181+00:00"}
