Due to its long half-life (30.17 y), the fate of 137Cs in the marine biota is of great interest. This study aims to evaluate, using food monitoring data, ecological half-lives (Teco) of 137Cs in marine biota caught offshore of Fukushima. The data were categorized into two regional groups (north and south) with respect to the FDNPP site, and the regional 137Cs concentration trend and estimated Teco in the marine biota were appraised. Although 137Cs concentration in the seawater in the south was higher than that in the north, Teco values remained relatively consistent among common species of both regions. Teco was then compared with biological half-life (Tb) estimated in laboratory settings. The ratios of Teco to Tb were inconsistent among different groups of marine species. The ratios of Teco to Tb for brown seaweed and bivalves were approximately 1, and for demersal fish ranged from 4.4 to 16.1. The reasons for different ratios of Teco and Tb values may be attributed to environmental and ecological factors, such as different trophic levels.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0013-936X","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":"Iwata, Kayoko"}],"nameIdentifiers":[{"nameIdentifier":"465476","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tagami, Keiko"}],"nameIdentifiers":[{"nameIdentifier":"465477","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uchida, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"465478","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岩田 佳代子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465479","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上 恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465480","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"465481","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":"Ecological half-lives of radiocesium in 16 Species in marine biota after the TEPCO's Fukushima daiichi nuclear power plant accident","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Ecological half-lives of radiocesium in 16 Species in marine biota after the TEPCO's Fukushima daiichi nuclear power plant accident"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-12-16"},"publish_date":"2013-12-16","publish_status":"0","recid":"46684","relation_version_is_last":true,"title":["Ecological half-lives of radiocesium in 16 Species in marine biota after the TEPCO's Fukushima daiichi nuclear power plant accident"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:48:50.403343+00:00"}
