Pine needles formed in the previous year were collected in early spring before the formation of any new-year needles. The pine-needle samples collected from the campus were rinsed with acetone and distilled water using a supersonic cleaner and processed chemically by an acid-alkali-acid treatment to get rid of fats and oils as well as other pollutions contaminating the sample surface, and finally dried in an electric oven. A part of the samples were combusted to produce CO2 and the produced CO2 was changed to graphite for ^\u003c14\u003eC measurements with an AMS ^\u003c14\u003eC system at Nagoya University. The measured ^\u003c14\u003eC concentration was given in the ratio of sample ^\u003c14\u003eC/^\u003c12\u003eC to that of standard. For both sample and standard, isotopic fractionation was corrected. In addition, the decrease of ^\u003c14\u003eC concentration by radioactive decay for the sample from the year of collection to the year of ^\u003c14\u003eC measurement, and that for the standard from AD1950 to the year of ^\u003c14\u003eC measurement, were corrected. The following results were obtained in the present experiment: (1) ^\u003c14\u003eC concentrations were lower for the needles grown along the road with heavy traffic by about 1-2.5% than those grown at other places in the campus. This is caused by the local dilution of atmospheric ^\u003c14\u003eCO2 by ^\u003c14\u003eC-free CO2 exhausted from motor vehicles. (2) the values of ^\u003c14\u003eC concentration in average for the needles grown in the Higashiyama Campus were lower by 6.2% and 7.4% in 2005 and 2008, respectively, compared to an average value of 1.081±0.016 for the plants grown in the rather clean atmosphere almost free from artificial CO2 at the Tibetian Plateau at the altitude of 5000m above the mean sea level. (3) ^\u003c14\u003eC concentrations of the needle samples grown at the Higashiyama campus in 2008 is lower than those grown in 2005. This suggests that the Suess effect is getting larger in the Nagoya city area by about 1% in 2008 than in 2005.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "第22回名古屋大学年代測定総合研究センターシンポジウム平成21(2009)年度報告", "subitem_description_language": "ja", "subitem_description_type": "Other"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/sumrua.21.126", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "名古屋大学年代測定資料研究センター", "subitem_publisher_language": "ja"}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "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": "中村, 俊夫", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "83108", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "太田, 友子", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "83109", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "NAKAMURA, Toshio", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "83110", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "OHTA, Tomoko", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "83111", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "21-19.pdf", "filesize": [{"value": "5.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 5300000.0, "url": {"label": "21-19.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/12863/files/21-19.pdf"}, "version_id": "d3046321-ee72-44be-b232-e2fd82140c41"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "atmospheric CO2", "subitem_subject_scheme": "Other"}, {"subitem_subject": "^\u003c14\u003eC concentration", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Suess effect", "subitem_subject_scheme": "Other"}, {"subitem_subject": "fossil fuel", "subitem_subject_scheme": "Other"}, {"subitem_subject": "pine needle", "subitem_subject_scheme": "Other"}, {"subitem_subject": "大気中二酸化炭素", "subitem_subject_scheme": "Other"}, {"subitem_subject": "^\u003c14\u003eC濃度", "subitem_subject_scheme": "Other"}, {"subitem_subject": "シュース効果", "subitem_subject_scheme": "Other"}, {"subitem_subject": "化石燃料", "subitem_subject_scheme": "Other"}, {"subitem_subject": "松葉", "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": "環境試料の^\u003c14\u003eC濃度変動 : 名古屋大学東山キャンパスに生育する松の葉の^\u003c14\u003eC濃度の経年変動と生育場所依存性", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "環境試料の^\u003c14\u003eC濃度変動 : 名古屋大学東山キャンパスに生育する松の葉の^\u003c14\u003eC濃度の経年変動と生育場所依存性", "subitem_title_language": "ja"}]}, "item_type_id": "9", "owner": "1", "path": ["1318"], "permalink_uri": "https://doi.org/10.18999/sumrua.21.126", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2011-05-11"}, "publish_date": "2011-05-11", "publish_status": "0", "recid": "12863", "relation": {}, "relation_version_is_last": true, "title": ["環境試料の^\u003c14\u003eC濃度変動 : 名古屋大学東山キャンパスに生育する松の葉の^\u003c14\u003eC濃度の経年変動と生育場所依存性"], "weko_shared_id": -1}
