三重県岩田川下流域の水質特異性 近藤, 雅秋 コンドウ, マサアキ KONDO, Masaaki 452 Iwata River water quality dissolved oxygen chloride ion water temperature application/pdf Water pollution in tidal area of the Iwata River was investigated. Mie Prefecture provides data of dissolved oxygen (DO), chloride ion (Cl), and water temperature (WT) in reports of water quality of rivers, seas, and groundwater. Three kinds of water quality were subject to analysis. Rivers were classified according to ranking, relationship between the values at various view points, and cluster analysis. The rank of DO in the Iwata River was low in Mie Prefecture. DO in the Iwata River was both oxygen depleted and unsaturated. The oxygen depleted condition was less than 6 mg/L. Cl in the Iwata River was large because of saltwater intrusion. WT was larger than the average value in Mie Prefecture. 原著論文 / Original Article 三重大学生物資源学部 2003-03-15 jpn departmental bulletin paper VoR http://hdl.handle.net/10076/2209 https://mie-u.repo.nii.ac.jp/records/5935 0915-0471 AN10073846 三重大学生物資源学部紀要 = The bulletin of the Faculty of Bioresources, Mie University 30 1 12 https://mie-u.repo.nii.ac.jp/record/5935/files/KJ00000693324.pdf application/pdf 889.1 kB 2017-02-18
