Water samples were collected every one hour during July 23-24 1987 from the Minami-Asakawa River and sewage effluents into it. Mearldaily loading and budgets of some bioelements, such as carbon, nitrongen and phosphorrs, were estimated. the fluxeds of suspended matter, organic carbons and ammoioum appeared to remove by self-purification pocesses. On the other hand, those of nitrate, nitrite and chlorophyll a, which were considered to be produced in situ, increased with the river flow. From these results, it was suggested that the river is not only the place for transportation of bioelements but also that for their metabolism.
