概要:

application/pdf<br />Departmental Bulletin Paper<br />The contaminations of anion surfactants in Tone River and their relations with water temperatures and the amounts of flowing water were studied. The data were measured by Gun … ma Prefectural Office. Further, the relation of the biodegradation of the anion surfactants and water temperature were examined by the river die-away test. 1) The amounts of Methylene Blue Active Substance(MBAS), a marker of anion surfactants in water, showed good correlation with the water temperature and the amounts of flowing water(multiple correlation coefficient: 0.915, coefficient of determination: 0.839). 2) The river die-away tests were done at 6, 20 and 27℃. MB AS disappeared after 10 days at 20℃. However, 92% of MBAS still remained after 2 weeks at 6℃. Considering that the water temperature of Tone River in winter is around 6℃, the contaminated anion surfactants in the river in winter could not be partially degraded. 続きを見る
