Abstract
The aim of this study is through animal fecal
sterols in different layers of bottom sediment
located at the downstream of the animal
raising farms to study the temporal changes of
livestock wastewater pollution. 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.
