Under) were separated into six parts according to grain size. Mercury concentrations were found in all samples， with the level being fairly dependent on the size factor of the sediment. The highest concentrations　of mercury have been detected in the group of 1?5μ，however，when only boiling with 0.1　N H_2S0_4 under a condenser as pretreatment， mercury in sediments has not been detected.　　　From　the　experiments described，we　may conclude that mercury　in　river-water from the River Muka is present not in solution，but as a dispersion of fine grain ore cinnabar，and its grain size is about 5?10μ.","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"32386","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SASAKI, Mitsuo"}]},{"nameIdentifiers":[{"nameIdentifier":"32387","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OKA, Hiroshi"}]},{"nameIdentifiers":[{"nameIdentifier":"32388","nameIdentifierScheme":"WEKO"}],"names":[{"name":"INOUE, Sadanobu"}]},{"nameIdentifiers":[{"nameIdentifier":"32389","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KIKUCHI, Takashi"}]}]},"item_2_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"北見工業大学"}]},"item_2_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐々木, 満雄"}],"nameIdentifiers":[{"nameIdentifier":"32382","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岡, 宏"}],"nameIdentifiers":[{"nameIdentifier":"32383","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"井上, 貞信"}],"nameIdentifiers":[{"nameIdentifier":"32384","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"菊地, 敬"}],"nameIdentifiers":[{"nameIdentifier":"32385","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":"2016-11-22"}],"displaytype":"detail","filename":"7-1-12.pdf","filesize":[{"value":"2.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"7-1-12.pdf","url":"https://kitami-it.repo.nii.ac.jp/record/6380/files/7-1-12.pdf"},"version_id":"cb082aa1-549c-4425-8118-9667eeb1f791"}]},"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":"無加川の水銀に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"無加川の水銀に関する研究"}]},"item_type_id":"2","owner":"1","path":["23"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-04-09"},"publish_date":"2007-04-09","publish_status":"0","recid":"6380","relation_version_is_last":true,"title":["無加川の水銀に関する研究"],"weko_creator_id":"1","weko_shared_id":3},"updated":"2022-12-13T02:19:41.659633+00:00"}
