| Abstract |
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. |
