At 1, 3, 7, 14, 30, 60 and 180 days, three soil fractions, (a) water soluble and ion exchangeable, (b) specifically adsorption, and (c) organically bound fractions, were determined by selective extraction methods with 0.05M calcium chloride (CA), 0.5M acetic acid and 0.1M sodium pyrophosphate, respectively.\nThe results showed that the relative amount (Qra) of CA extractable Cs decreased rapidly to almost zero within a few days after being freshly introduced to the soil samples. The Qra of CA extractable Sr in all the samples was almost the same during 6-month. For Mn, the Qra of CA-Mn in Gray lowland soils decreased throughout the experiment, but the soil redox conditions did not affect on the change. the Qra of CA-Mn in Andosol was much lower than that in Gray lowland soils. Interestingly, for Tc, the Qras of CA-Tc was lower in the anaerobic condition than in the aerobic conditions in both soils. Due to the reduce of the amounts of water soluble and exchangeable forms of these elements in soils, the amounts of these elements entering the food chain probably decrease gradually with time.","subitem_description_type":"Abstract"}]},"item_10003_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japan Atomic Energy Research Institute"}]},"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":"Tagami, Keiko"}],"nameIdentifiers":[{"nameIdentifier":"547848","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uchida, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"547849","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上 恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"547850","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"547851","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 paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Time dependence on Tc, Mn, Sr and Cs behaviors in agricultural soils under aerobic and anaerobic conditions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Time dependence on Tc, Mn, Sr and Cs behaviors in agricultural soils under aerobic and anaerobic conditions"}]},"item_type_id":"10003","owner":"1","path":["2"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-06-05"},"publish_date":"2006-06-05","publish_status":"0","recid":"53681","relation_version_is_last":true,"title":["Time dependence on Tc, Mn, Sr and Cs behaviors in agricultural soils under aerobic and anaerobic conditions"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:09:50.240508+00:00"}
