The lake is known as one of the most polluted lakes in Japan. Water sampling was made once in a week dur ing the period from June 1985 to June 1988. Each water sample was filtered through a 0.45 gm membrane filter and used for the determination of concentrations. From the se results, the mean values of the dissolved TOC of spring, summer, autumn and winter seasons in the western part of Lake Inba-numa were 8.8 mg/l, 9.8 mg/l, 9.4 me and 8.3 mg/l, respectively. The TOC value tends to increase from June to September and decrease from November to March excepting aquatic plant area but in the aquatic plant area this tends to increase from October to November. The dissolved TOC of summer season was composed of proteins, 22-27 %; carbohydrates, 24-32 %; volatile organic acids, 1022 % ; anionic surfactants, 2-3 % ; humic acids, 1-3 %; lignin, 1-4; tannin, 2-4 %; urea, 4-9 %; and lipids, 1-4 %. The sum of the components of proteins, carbohydrates, volatile organic acids and anionic surfactants was 68.8 % of dissolved TOC and that in the influent of domestic wastewater about 67 %. As one of the causes of the pollution of the western part of Lake Inba-numa, the influx of organic substances from the catchment area similar to those present in the domestic wastewater, may contribute greatly. The western part of Lake Inba-numa may be strongly affected by the matter production of Trapa vegetation."},{"@language":"ja","@value":"浅水性湖沼水中の溶解性有機物の挙動を開らかにするために,西印旛沼(平均水深1 .9m,面積5.29km<SUP>2</SUP>,千葉県)を選んで,水質の変動および溶解性有機物の組成について,1985年6月から1988年6月の期間に調査検討した。試料水を0.45μmメンブランフィルターで濾過し,濾液中のTOC濃度およびタンパク質など9項目を測定し,溶解性有機物濃度に対するタンパク質,炭水化物などの組成割合を求めた。溶解性有機物の組成割合は季節によって異なり,たとえば夏季の場合,タソパク質,25～36%;炭水化物・24～32%;揮発性有機酸,10～22%;アニオン界面活性剤,2～3%,フミン酸,1～3%;リグニン,1～4%;タンニソ,2～4%;尿素,4～9%および脂質,1～4%の範囲にあった。冬季は特にタンパク質とフミン酸がいちじるしく増加する傾向にあった。タンパク質,炭水化物,揮発性有機酸およびアニオン界面活性剤の組成割合の湘から判断すると西印旛沼の汚濁要因の一つは,集水域から流入する家庭下水に類似した有機物の寄与がいちじるしいことがわかった。また浅水性湖沼内では水生植物の代謝により溶解性有機物の増加も十分考慮しなければならないこともわかった。"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1030285133400284421","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"90155101"},{"@type":"NRID","@value":"1000090155101"},{"@type":"NRID","@value":"9000002316074"},{"@type":"NRID","@value":"9000006486633"},{"@type":"NRID","@value":"9000391900330"},{"@type":"NRID","@value":"9000254790606"},{"@type":"NRID","@value":"9000256681237"},{"@type":"NRID","@value":"9000254537556"},{"@type":"NRID","@value":"9000254790538"},{"@type":"NRID","@value":"9000018296438"},{"@type":"NRID","@value":"9000256099986"},{"@type":"NRID","@value":"9000007291910"},{"@type":"NRID","@value":"9000005261054"},{"@type":"NRID","@value":"9000001028395"},{"@type":"NRID","@value":"9000254537195"},{"@type":"NRID","@value":"9000258216313"},{"@type":"NRID","@value":"9000258216331"},{"@type":"NRID","@value":"9000256041732"},{"@type":"NRID","@value":"9000256680198"},{"@type":"NRID","@value":"9000254301340"},{"@type":"NRID","@value":"9000254103268"},{"@type":"NRID","@value":"9000401713648"},{"@type":"NRID","@value":"9000255915436"},{"@type":"NRID","@value":"9000258216286"},{"@type":"NRID","@value":"9000020453069"},{"@type":"NRID","@value":"9000256059383"},{"@type":"NRID","@value":"9000253307356"},{"@type":"NRID","@value":"9000256730213"},{"@type":"NRID","@value":"9000007964966"},{"@type":"NRID","@value":"9000256680153"},{"@type":"NRID","@value":"9000254791098"},{"@type":"NRID","@value":"9000256044172"},{"@type":"NRID","@value":"9000018348979"},{"@type":"NRID","@value":"9000254301296"},{"@type":"NRID","@value":"9000254790639"},{"@type":"NRID","@value":"9000257915487"},{"@type":"NRID","@value":"9000010264041"},{"@type":"NRID","@value":"9000020093054"},{"@type":"NRID","@value":"9000254723267"},{"@type":"NRID","@value":"9000256049679"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0170323"}],"foaf:name":[{"@language":"en","@value":"TATSUMOTO
