Cultivation of paddy rice was restrained where radiocesium concentration (CsConc) of soil exceeded 5,000 Bq/kg. However, brown rice whose CsConc exceeded provisional regulation value for CsConc in brown rice (500 Bq/kg) was produced in several non-restrained paddy fields. In this paper, we compiled soil properties for analyzing cause of high CsConc in brown rice and deliberated on cause in terms of soil properties. The 36 topsoil samples were collected from 5 paddy fields in Obama, Nihonmatsu city where CsConc in brown rice exceeded 500 Bq/kg were detected, and from 31 paddy fields in Fukushima, Date and Nihonmatsu city to examine factors for high CsConc in brown rice. The CsConc of brown rice and ExK2O in topsoil in Obama (5 sites) ranged from 92 to 453 Bq/kg and from 1.8 to 10.1 mg/100g, respectively. The CsConc of topsoil and brown rice in the other sites (31 sites) was 6,090 Bq/kg in average and ranged from 2,320 to 11,700 Bq/kg and 570 Bq/kg in average and ranged from ND to 1,240 Bq/kg, respectively. As the average of CsConc in topsoil ranged from 3,840 to 7,170 in the sites that CsConc in brown rice showed less than provisional regulation value, the high CsConc in topsoil was not necessarily a cause of high CsConc in brown rice. ExK2O in topsoil was 9.7 mg/100g in average and ranged from 2.5 to 32.2 mg/100g. The average ExK2O in the sites that CsConc in brown rice exceeded provisional regulation value was as low as 6.8 mg/100g. In these cases, low ExK2O was one of the main causes of high CsConc in brown rice.","subitem_description_type":"Abstract"},{"subitem_description":"2011年3月11に発生した東京電力福島第一原子力発電所 (福島第一原発) の事故に伴い、放射性物質が大気中に放出された。農地の汚染も広範囲で起こり、水稲栽培に関しては土壌中の放射性セシウム濃度が5,000Bq/kgを超える水田で作付けが制限された。しかしながら2011年産で玄米中の放射性セシウム濃度が暫定規制値 (500Bq/kg)を超えるものが一部の水田で生産された。このためこれらの福島県、農水省は水田における要因解析を実施した。本論文ではこれらの要因解析に用いられた土壌特性のデータをとりまとめ、土壌特性からみた要因について考察を行った。二本松市旧小浜町の5水田と暫定規制値を超過した放射性セシウムの玄米が検出された水田 (22カ所) およびその周辺水田 (9カ所) の31地点 (要因解析調査地点) の合計36地点で作土の土壌試料を採取し分析に供した。作土の放射性セシウム濃度は2,320～11,700Bq/kg、玄米中の放射性セシウム濃度はND～1,240Bq/kgで、移行係数は0.02～0.34の範囲であった。小浜町の玄米の放射性セシウム濃度と交換性カリ含量はそれぞれ92 ～ 453Bq/kg、1.8 ～10.1mg/100gの範囲であった。また、要因解析調査地点における交換性カリ含量の平均値は9.7mg/100gで2.5～32.3mg/100gの範囲であった。特に規制値を超えた地点においては交換性カリの平均値は6.8mg/100gと低く、10mg/100gを超えた地点は3地点にすぎない。以上のように、土壌の交換性カリ含量が重要な要因の一つであることが明らかになった。一方で、玄米の放射性セシウム濃度と土壌特性との関係性を明確に特徴づけることはできなかった。また、土壌特性以外の要因、栽培管理・用水・周辺環境などの影響もあると思われるため、要因解明には多くの課題が残されている。","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00003012","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人 農業環境技術研究所"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.24514/00003012","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0911-9450","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"神山, 和則"},{"creatorName":"コウヤマ, カズノリ","creatorNameLang":"ja-Kana"},{"creatorName":"KOHYAMA, Kazunori","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"小原, 洋"},{"creatorName":"オバラ, ヒロシ","creatorNameLang":"ja-Kana"},{"creatorName":"OBARA, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"高田, 裕介"},{"creatorName":"タカタ, ユウスケ","creatorNameLang":"ja-Kana"},{"creatorName":"TAKATA, Yusuke","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"齋藤, 隆"},{"creatorName":"サイトウ, タカシ","creatorNameLang":"ja-Kana"},{"creatorName":"SAITO, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"佐藤, 睦人"},{"creatorName":"サトウ, ムツト","creatorNameLang":"ja-Kana"},{"creatorName":"SATO, Mutsuto","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"吉岡, 邦雄"},{"creatorName":"ヨシオカ, クニオ","creatorNameLang":"ja-Kana"},{"creatorName":"YOSHIOKA, Kunio","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"谷山, 一郎"},{"creatorName":"タニヤマ, イチロウ","creatorNameLang":"ja-Kana"},{"creatorName":"TANIYAMA, Ichiro","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-10-09"}],"displaytype":"detail","filename":"niaes_report_No34p63-73p.pdf","filesize":[{"value":"853.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"niaes_report_No34p63-73p.pdf","url":"https://repository.naro.go.jp/record/3137/files/niaes_report_No34p63-73p.pdf"},"version_id":"29b70683-9d6c-4ec3-8cb2-187f07c6e88a"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"2011年高濃度放射性セシウム汚染玄米発生の土壌要因","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"2011年高濃度放射性セシウム汚染玄米発生の土壌要因"},{"subitem_title":"Soil properties for analyzing cause of high radiocesium concentration in brown rice produced in 2011 in Fukushima prefecture","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"12","path":["414"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-12-20"},"publish_date":"2019-12-20","publish_status":"0","recid":"3137","relation_version_is_last":true,"title":["2011年高濃度放射性セシウム汚染玄米発生の土壌要因"],"weko_creator_id":"12","weko_shared_id":12},"updated":"2023-05-15T15:36:15.032319+00:00"}
