Endosulfan induces oxidative stress and changes on detoxication enzymes in the aquatic macrophyte Myriophyllum quitense

Myriophyllum quitense, when exposed to environmentally relevant concentrations of endosulfan (1) showed a generalized induction of both detoxication and antioxidant enzyme (glutathione-S-transferase, glutathione reductase, catalase) activities, as well as an increased content of hydrogen peroxide, indicating that this xenobiotic activates the protection system of the plant, increasing its capacity to scavenge reactive oxygen species.
