Seasonal changes of the concentration and TEQ values of PCB at 8 areas (A~H) involving 3 isolated island (F~H) areas were examined. The concentration of PCB in the summer in the range of 137~ 416 pg/m3 was higher than that in the winter in the range of 67~ 126 pg/m3 (p<0.01). The isolated islands showed a two or three-times higher concentration of PCB compared to the districted areas (p<0.01). Furthermore, to identify the source of PCB, a principal component analysis (PCA) and a chemical mass balance (CMB) method were applied. In isolated island areas, Kanechlor KC300 was a major source throughout the year, whereas Kanechlor KC400 in summer and the products by combustion in winter were found to be major sources in districted areas.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"分析化学, 58(4), pp.211-220; 2009","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"65073","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Honda, Takashi"}]},{"nameIdentifiers":[{"nameIdentifier":"65074","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Wada, Mitsuhiro"}]},{"nameIdentifiers":[{"nameIdentifier":"65075","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakashima, Kenichiro"}]}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本分析化学会"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2116/bunsekikagaku.58.211","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2009 The Japan Society for Analytical Chemistry."}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00222633","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05251931","subitem_source_identifier_type":"ISSN"}]},"item_2_text_62":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"Japan Society for Analytical Chemistry"}]},"item_2_version_type_16":{"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":"本多, 隆"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"和田, 光弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中島, 憲一郎"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"BunKag58_211.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"BunKag58_211.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/16812/files/BunKag58_211.pdf"},"version_id":"3839d714-9a0e-408b-a831-a97ad6878084"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"polychlorinated biphenyl","subitem_subject_scheme":"Other"},{"subitem_subject":"ambient air","subitem_subject_scheme":"Other"},{"subitem_subject":"principal component analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"chemical mass balance","subitem_subject_scheme":"Other"},{"subitem_subject":"Nagasaki prefecture","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"長崎県の大気中ポリ塩化ビフェニルの定量とその汚染特性評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"長崎県の大気中ポリ塩化ビフェニルの定量とその汚染特性評価"}]},"item_type_id":"2","owner":"2","path":["74"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-01-15"},"publish_date":"2010-01-15","publish_status":"0","recid":"16812","relation_version_is_last":true,"title":["長崎県の大気中ポリ塩化ビフェニルの定量とその汚染特性評価"],"weko_creator_id":"2","weko_shared_id":2},"updated":"2023-05-15T19:11:24.754528+00:00"}
