POD also acts on H2O2 and plays an important role in eliminating
H2O2 in organisms. In our study, TCS exhibited a different
impact on the activity of POD from that of SOD and CAT in A. fulica.
There was no significant change in the activity of POD in low TCS
concentrations. However, the POD activity was significantly inhibited
in the 340 mg kg group (p < 0.05; ANOVA; Fig. 4C).
