In this study, we tried to solve heavy-metal pollution and its state in rivers from both chemical and biological viewpoints. The sediment (sediment on the river bed and attached substances, etc.) was taken in rivers at the feet of old copper mines, Ishikawa prefecture. Its wet ashing and sequential extraction were performed. The total copper content and the copper contents of all fractions containing the types of associations between copper and the sediment were determined. The diatom taxa, growing in attached substances on psephite, were also identified. As a result, the correlation between the ratio of the exchangeable fraction (e.g. ion-exchangeable chemical species and carbonate) to the total contents of copper and the relative abundance (as the ratio of the number of each taxon to the total number of diatom) of Achnanthe minutissima, which is specified as an indicator diatom of heavy-metal pollution, was observed. The exchangeable fraction contained toxic species of copper. It seems that they have an effect on biota containg diaton in rivers.","subitem_description_type":"Abstract"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00011043","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Japan Society for Analytical Chemistry = 日本分析化学会"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2116/bunsekikagaku.53.883","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jsac.or.jp/index.html","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002905443/en/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jstage.jst.go.jp/article/bunsekikagaku/53/9/53_883/_article/-char/ja","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"The Japan Society for Analytical Chemistry (c) 2004"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00222633","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0525-1931","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"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":"山田, 隆史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"墨田, 迪彰"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中西, 良明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"本浄, 高治"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"SC-PR-HONJO-T-883.pdf","filesize":[{"value":"419.1 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-HONJO-T-883.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/11056/files/SC-PR-HONJO-T-883.pdf"},"version_id":"d5b518b1-405c-404d-9497-0815865a5aa8"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"石川県旧銅鉱山下の河川における付着珪藻群集の分布と化学種分析からみた重金属汚染状態(<特集>若手研究者の初論文特集)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"石川県旧銅鉱山下の河川における付着珪藻群集の分布と化学種分析からみた重金属汚染状態(<特集>若手研究者の初論文特集)"},{"subitem_title":"Heavy-metal pollution and its state in the diatom distribution along with heavy-metal speciation in rivers at the feet of old copper mines, Ishikawa prefecture(<Special Articles>The First Papers of Prospective Analytical Chemists)","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["937"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"11056","relation_version_is_last":true,"title":["石川県旧銅鉱山下の河川における付着珪藻群集の分布と化学種分析からみた重金属汚染状態(<特集>若手研究者の初論文特集)"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T10:56:14.922000+00:00"}
