They dissolve into the melt water of the snow sample and become reactive only after oxidative digestion with HClO_4 and HNO_3. The same organic metal compounds were found in atmospheric aerosols collected at Syowa Station and Mizuho Station, which suggests that these were incorporated into the snow from atmospheric aerosols. The above observation, in association with the finding that these organic metal compounds also exist in aerosols from the North Pacific as well as from the Southern Sea, indicates that these compounds are widely distributed in the global atmosphere and further suggests the existence of gaseous organic metal compounds in the air as a precursor of these compounds in the aerosols. The samples of snow from site S25 and atmospheric aerosols from the Southern Sea were subjected to volatilization experiments in the vacuum and the vapor was collected in the cold trap immersed into the liquid N_2. Significant amounts of the heavy metals were found in the cold trap, showing the volatile nature of these heavy metal elements contained in the Antarctic snow and aerosols. These results support the idea that the gaseous organic metal compounds exist in the air as a precursor of aerosols. Experiments to directly determine the gaseous organic metal compounds are now in progress.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00003617","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA10756213","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Water Research Institute, Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Water Research Institute, Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"National Institute for Environmental Studies"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"ABSTRACT"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1990-01-01"}],"displaytype":"detail","filename":"KJ00000767823.pdf","filesize":[{"value":"78.7 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000767823","url":"https://nipr.repo.nii.ac.jp/record/3617/files/KJ00000767823.pdf"},"version_id":"ba193a99-8506-4171-889c-c63b93ba50c8"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"CHEMICAL NATURE OF HEAVY METAL ELEMENTS IN ANTARCTIC SNOW","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"CHEMICAL NATURE OF HEAVY METAL ELEMENTS IN ANTARCTIC SNOW"}]},"item_type_id":"1","owner":"4","path":["527"],"pubdate":{"attribute_name":"公開日","attribute_value":"1990-01-01"},"publish_date":"1990-01-01","publish_status":"0","recid":"3617","relation_version_is_last":true,"title":["CHEMICAL NATURE OF HEAVY METAL ELEMENTS IN ANTARCTIC SNOW"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:31:24.960097+00:00"}
