“…Li et al (2014) reported that the response of the GSH-PX activity in E. Andrei during on-going Al exposure was similar to that of SOD. Similar to our results, Zhou et al (2016) found no significant corre-lation between the activities of CAT and POD in Eisenia fetida exposure to Cd 2+ with different exposure time (0-30 days). Zhang et al (2009) found that Cd at low concentration (7.01 ng cm −2 ) induced an increase in the activity of CAT, but high concentration (10.53 ng cm −2 ) inhibited the enzymes, and this was reflected in an inverted U-shaped curve.…”

“…While little is known about of the biochemical and molecular responses of E. fetida to soil acidity, they are expected to be more informative and may link to the inhibition of growth and reproduction, thus providing a more comprehensive understanding of the effects of soil acid stress on earthworms (Wu et al 2011;Zhang et al 2015a). The antioxidant enzymes would have certain synergetic effects on cleaning out reactive oxygen species (ROS) caused by normal metabolism or environment stress (Hu et al 2016;Zhou et al 2016). They protect cells against the adverse effects of ROS.…”

“…As the result of this study is not consistent with the general strategy of earthworms under toxin stress, our findings support the hypothesis that the variation in body weight of both worms species was mostly related to food supply rather than metal contamination. This could be explained by the low Cd availability due to the interaction between Cd and different soil materials [ 36 ]. Soil properties were reported to affect metal bioavailability and change their impact on earthworms’ physiology [ 37 ].…”
