Fecal sterols are presented in mammalian feces. They are very stable in both anaerobic environment and the bottom sediment. Thus, fecal sterols can be used to study the time trend difference of biota pollution. This project selected treated wastewater discharging downstream of the densely piggery raising area and aged pig farm destroyed by foot-and-mouth disease outbreak to compare the sterols difference in different bottom sediment layers of previous pollution. The results showed that bottom layer of the sediment in current raising farm had a higher concentration of sterols than the upper layer but did not have sterol profile difference. On the contrary, not only the concentration but also the profiles of the sterol in bottom layer of aged farm were all different from the upper layer. An easy distinguishable of the pollution due to time difference can be reached.application/pdf76208 bytesapplication/pdfzh-TW國立臺灣大學獸醫學系暨研究所糞脂醇污染指標時序性變化氣相層析質譜儀分析fecal sterolspollution indicatorstemporal changesGC/MSreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/28681/1/892313B002071.pdf
