However, it is not well known that whether there are any climate change effects on TFs of Se and As or not. In this study, therefore, Se and As were measured in brown rice and soil collected from the northern and the southern parts of Japan considering cool and warm areas, respectively, and compare the obtained TF-Se and TF-As between warm and cool areas.\nFor sampling site selection, a criterion was set, that is, prefectures where temperature exceed more than 25 degrees C for 140 or more days were classified as warm areas, and less than 70 days were classified as cool areas. Seven and twelve samples were collected in the worm and the cool areas, respectively. The soil and crop samples were separately digested with mineral acids (a mixture of HNO3, HF and HClO4) using a microwave digester (CEM, Mars 5). After diluting the acid solutions to a suitable concentration, elements in both crop and soil samples were measured with a reaction cell type ICP-MS (Agilent 7500c).\nConcentrations of Se and As in soil ranged 0.24-0.58 and 4.1-8.3 mg/kg-dry in warm areas, respectively, and 0.39-1.2 and 8.6-19 mg/kg-dry in cool areas, respectively. For TFs, no significant difference was found for TF-As by areas, however, TF-Se was higher in warm areas.","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":"SETAC Asia Pacific 2012 Meeting","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":"Uchida, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"696870","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tagami, Keiko"}],"nameIdentifiers":[{"nameIdentifier":"696871","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"696872","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上 恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"696873","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":"The effect of climate differences on the transfer of selenium and arsenic from soil to brown rice in Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The effect of climate differences on the transfer of selenium and arsenic from soil to brown rice in Japan"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-09-29"},"publish_date":"2012-09-29","publish_status":"0","recid":"70920","relation_version_is_last":true,"title":["The effect of climate differences on the transfer of selenium and arsenic from soil to brown rice in Japan"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:57:18.033944+00:00"}
