本 硏究에 貴重한 助言을 해주신 延世大學校 權肅杓敎授와 慶熙大學校 崔範錫敎授에게 感謝를 表하며, 慶熙大學院 및 學部學生들의 手苦에 感謝합니다. 本 論文은 韓國學術振興財團 '85尖端科學 技術分野 硏究支援에 의한 硏究結果입니다. To assess the fecal contamination, the coprostanol was measured by GC-MS in Chung Ryang stream from November 3, 1985 to May 25, 1986, which was much polluted by municipal sewage and night soil from the crowd residential area, a part of Seoul, along the stream. That was compared with the coliform group and was analyzed statistically. The result was obtain as follows ; The coprostanols were determined at 0.6-1.5 ng/1 in the range of concentrations. The concentrations were not significantly different from the up-stream to the down-stream. The numbers of coliform groups were gradually increased as lower the streams. It was shown in no relationships between the coprostanol and tee number of coliform groups in the stream(r = 0.18). With the above results, it is discussed that the coprostanol is not reliable in the determination of fecal contamination as an index of water qualities.

Abstract Environmental waters such as river and lake waters are most likely polluted by a numerous number of chemicals produced and emitted by human activities nowadays. Bioassays are considered to be rational methodologies for evaluating their toxicities against human beings and ecosystems. The various kinds of bioassays data for chemicals have been accumulated so far in the literature. Organizing bioassays data of various chemicals was tried in this work in order to make use of those data much more effectively and practically for the toxicity control and management of environmental waters.
