After a 14-d exposure, there was no significant change in the
activity of POD below 118 mg kg1. In contrast, the POD activity
decreased with increasing TCS concentration above 118 mg kg1,
and was significantly inhibited in the 340 mg kg1 group. After a
28-d exposure, a slight increase was observed in the concentrations
below 69 mg kg1, but it was not significantly higher than
the control. The activity of POD decreased as TCS concentration
