The fish were divided into three groups based on their size and age and reared in 137-Cs-spiked water. The concentration of 137-Cs in the whole body of the live fish was measured at regular intervals up to 60 days. A significant accumulation of 137-Cs was found, but a steady state condition was not achieved by the end of the experiment. The bioaccumulation factors at steady state and the required time to reach steady state were estimated to be 1.55 and 255 days, 1.76 and\n180 days and 1.99 and 160 days for large, medium and small size fish, respectively.\nTo determine the effective half-life of 137-Cs, the fish were transferred and reared \nin the non-contaminated host water. The concentration of the remaining 137-Cs in the\nwhole body of the live fish was measured up to 66 days. The average effective half-\nlife of 137-Cs in the fish species was found to be ~142 days for fish of all sizes.\nThe distribution of 137-Cs in different organs/tissues of the fish was determined.\nAccumulation of 137-Cs in muscle/flesh of the fish was found to be ~75% of whole \nbody accumulation. The uptake rate and the retention capability of juvenile fish were\nfound to be higher and therefore, these were more susceptible to 137-Cs than adult and\nold fish, and could be an important source of 137-Cs in the human food chain.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0265-931X","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":"M., Abdul Malek"}],"nameIdentifiers":[{"nameIdentifier":"433072","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakahara, Motokazu"}],"nameIdentifiers":[{"nameIdentifier":"433073","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakamura, Ryouichi"}],"nameIdentifiers":[{"nameIdentifier":"433074","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中原 元和","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"433075","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中村 良一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"433076","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":"Uptake, retention and organ/tissue distribution of 137Cs by Japanese catfish (Silurus asotus Linnaeus)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Uptake, retention and organ/tissue distribution of 137Cs by Japanese catfish (Silurus asotus Linnaeus)"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-12-07"},"publish_date":"2004-12-07","publish_status":"0","recid":"43553","relation_version_is_last":true,"title":["Uptake, retention and organ/tissue distribution of 137Cs by Japanese catfish (Silurus asotus Linnaeus)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:25:51.493920+00:00"}
