The results of the analyses are summarized as follows : 1) The observation sites where the mean pH values of rain samples collected every rain event in the warm season are more than 5.5 are distributed in the northeastern and the southwestern parts of the area investigated. 2) The maen values of NO_3^-/nss-SO_4^<2-> concentration ratio (N/S ratio) decrease with distace toward the east, and in the northeastern part of Chiba Prefecture, the ratio less than 0.3 are observed in both the warm and the cool seasons. 3) The pH value shows high negative correlation with fractional acidity ([H^+]/([nss-SO_4^<2->]+[NO_3^-]) in the warm season. The relation between the pH value and the fractional acidity (A) can be expressed by follows. pH=-2.69A+5.69 r=-0.71 4) The mean value of NH_4^+/nss-Ca^<2+> concentration ratio increase with the distance toward the west of the study area, in both the warm and the cool seasons.","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN1041551X","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"敬愛大学国際学部"}]},"item_3_text_7":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Faculty of International Studies, Keiai University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中村, 圭三"},{"creatorName":"ナカムラ, ケイゾウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"7024","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakamura, Keizo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"7025","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":"2016-08-18"}],"displaytype":"detail","filename":"KJ00000195387.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"KJ00000195387.pdf","url":"https://keiai.repo.nii.ac.jp/record/1604/files/KJ00000195387.pdf"},"version_id":"064d5bc7-7043-4636-9387-3d2a80fbd9b9"}]},"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":"千葉県北部における酸性雨の地域的特性について(3) : 1996年度 観測結果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"千葉県北部における酸性雨の地域的特性について(3) : 1996年度 観測結果"},{"subitem_title":"Regional Characteristics of Acid Rain in the Northern Part of Chiba Prefecture: Part3","subitem_title_language":"en"}]},"item_type_id":"3","owner":"3","path":["159"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-08-18"},"publish_date":"2016-08-18","publish_status":"0","recid":"1604","relation_version_is_last":true,"title":["千葉県北部における酸性雨の地域的特性について(3) : 1996年度 観測結果"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T10:43:11.068768+00:00"}
