Ibuki. The lake sediments contain high contents of arsenic (As). To investigate the concentration of As into lake sediment, we analyzed the element and isotopic compositions of lake sediments as well as bedrocks, rivers water, and springs water in the surround region. The average content of As in lake sediment samples (n = 83) was 68 ± 32 μg/g. The C/N ratio (30.4 ± 7.4) and δ^13CTOC (–28.1 ± 0.4‰) of silty–clay layers indicate that the organic matter was mainly input of land–derived C3 plants. In addition, the δ^13CTOC values show a weak inverse correlation with the As contents (R = –0.67), indicating that the dissolved As was supplied into paleolake together with the land plants. The δ^34S values of paleolake sediment samples (–1.7 ± 2.5‰) approximately coincide with that of SO4^2– (70μM) in the present Ane River (–4.0 ± 0.8‰). This observation is explained by diagenetic pyrite formation in a closed system under low SO4^2– concentrations. The δ^34SSO4 and δ^18OSO4 in SO4^2– in the present rivers indicate that most of SO4^2– in the catchment is derived from the pyrite oxidation in bedrocks. This is supported by δ^34S values of bedrock samples (–22.9 ~ –2.2‰) which contain ~3 μg/g of As. Because S and As show the similar behavior in the environment, the concentration of As into paleolake sediments probably resulted from dissolution of bedrocks, followed by the adsorption on organic matter and Fe oxyhydroxide in river and lake water columns.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/nagubc.7.9","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋大学宇宙地球環境研究所年代測定研究部","subitem_publisher_language":"ja"},{"subitem_publisher":"Division for Chronological Research, Institute for Space‒Earth Environmental Research, Nagoya University","subitem_publisher_language":"en"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"益木, 悠馬","creatorNameLang":"ja"},{"creatorName":"Masuki, Yuma","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"勝田, 長貴","creatorNameLang":"ja"},{"creatorName":"Katsuta, Nagayoshi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"内藤, さゆり","creatorNameLang":"ja"},{"creatorName":"Naito, Sayuri","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"由水, 千景","creatorNameLang":"ja"},{"creatorName":"Yoshimizu, Chikage","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"陀安, 一郎","creatorNameLang":"ja"},{"creatorName":"Tayasu, Ichiro","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"南, 雅代","creatorNameLang":"ja"},{"creatorName":"Minami, Masayo","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-01-05"}],"displaytype":"detail","filename":"009-014_2022.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/2008742/files/009-014_2022.pdf"},"version_id":"44efe1b5-5af1-41bd-aa2d-56100bcb85bc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"lacustrine sediment","subitem_subject_scheme":"Other"},{"subitem_subject":"arsenic","subitem_subject_scheme":"Other"},{"subitem_subject":"stable isotopes","subitem_subject_scheme":"Other"},{"subitem_subject":"Ane River","subitem_subject_scheme":"Other"}]},"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":"安定同位体組成による姉川古せき止め湖堆積物のヒ素の堆積環境","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"安定同位体組成による姉川古せき止め湖堆積物のヒ素の堆積環境","subitem_title_language":"ja"}]},"item_type_id":"40001","owner":"17","path":["1703659440327"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-01-05"},"publish_date":"2024-01-05","publish_status":"0","recid":"2008742","relation_version_is_last":true,"title":["安定同位体組成による姉川古せき止め湖堆積物のヒ素の堆積環境"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2024-01-05T05:06:41.472874+00:00"}
