| Abstract |
The distribution and fate of anionic surfactants in Jungrang stream and in down stream of Han river tributary and in Jinwi stream of Ansung stream tributary were examined. The concentrations of linear alkylbenzene sulfonates(LAS) in river were determined by gas-liquid chromatogaphy. The ratio of concentrations of LAS to those of methylene blue active substances(MBAS) were estimated to 27-31% in Jungrang stream and 27-65% in Jinwi stream and 35-58% in down stream of Han river tributary. However, levels of LAS and its contribution to the MBAS in rivers was found to vary with the nature of the sampling location, i. e. depending whether it was above, below or in the vicinity of a sewage effluent discharge. The concents of LAS and carbon number of alkyl chain were high in Jungrang stream and low in Han river. In its seasonal variations, it is high in November and low in August. |
