National Institute of Radiological Sciences (NIRS) located in Chiba, where 220 km away from FDNPP, also had radioactive deposition from FDNPP in March. In newly emerged tree leaves collected at NIRS in late April 2011, radiocesium were found although they had not contaminated directly from the deposition. According to the previous reports and our observation, we concluded that radiocesium was absorbed from tree surface, e.g. leaves (old leaves of evergreen trees) and stems; radiocesium uptake through roots would be negligible.\nIn autumn, deciduous trees shed leaves, and a part of leaves fall from evergreen trees. It is known that some nutrients in grass leaves withdrawn before abscission, therefore, we thought it would be possible that leaves return radiocesium to tree stems and trunks before leaf-fall. If so, radiocesium remained in trees for a long time period.","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 6th SETAC World Congress","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":"Tagami, Keiko"}],"nameIdentifiers":[{"nameIdentifier":"636625","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uchida, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"636626","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上 恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"636627","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"636628","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":"Change of radiocesium concentration in tree leaves before and after abscission","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Change of radiocesium concentration in tree leaves before and after abscission"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-31"},"publish_date":"2012-05-31","publish_status":"0","recid":"64599","relation_version_is_last":true,"title":["Change of radiocesium concentration in tree leaves before and after abscission"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:09:47.906262+00:00"}
