Sb and Pb concentrations, and Pb stable isotopic ratios were analysed to study thye historical atmospheric deposition records and sources of Sb over the past 15 centuries. The Sb concentration was 4.21 mg/kg in sediments, its vertical distribution of Sb shows three large peaks in recent centuries, 1799, 1896 and 1944, coincided with Sb contamination from large wars, respectively. The peak in 1920 responded the large earthquake that happened in northern China, which was not far away from Lake Qinghai. The Sb/Pb ratio, 206Pb/207Pb and 208Pb/206Pb results suggest that Sb and Pb were probably from the ores in South China and coals in North China before 1965, but obviously from uses of leaded gasoline after 1965.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0026-265X","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Xu, Libin"}],"nameIdentifiers":[{"nameIdentifier":"457174","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wu, Fengchang"}],"nameIdentifiers":[{"nameIdentifier":"457175","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zheng, Jian"}],"nameIdentifiers":[{"nameIdentifier":"457176","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Xie, Qianli"}],"nameIdentifiers":[{"nameIdentifier":"457177","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Li, Huixian"}],"nameIdentifiers":[{"nameIdentifier":"457178","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Liao, Haiqing"}],"nameIdentifiers":[{"nameIdentifier":"457179","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhao, Xiaoli"}],"nameIdentifiers":[{"nameIdentifier":"457180","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Guo, Fei"}],"nameIdentifiers":[{"nameIdentifier":"457181","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鄭 建","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"457182","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ｌｉａｏ Ｈａｉｑｉｎｇ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"457183","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Sediment records of Sb and Pb stable isotopic ratios in Lake Qinghai","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Sediment records of Sb and Pb stable isotopic ratios in Lake Qinghai"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-12-06"},"publish_date":"2010-12-06","publish_status":"0","recid":"45956","relation_version_is_last":true,"title":["Sediment records of Sb and Pb stable isotopic ratios in Lake Qinghai"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:57:35.940206+00:00"}
