“…Similar to this study, stimulated GPOX was reported in Cu-exposed Lemna gibba and Lemna minor [4], Brassica juncea [23], Lupinus luteus [24], Phaseolus vulgaris [25], Astragalus neo-mobayenii [26] and Allium sativum [27]. In addition, it was observed, that induction of GPOX activity in copper-treated plants of Beta vulgaris L. was higher in young leaves than in old leaves [28].…”

“…Changes in the activity of peroxidases, especially GPOX, are used as sensitive markers of abiotic and biotic stresses in plants [22]. The activity of this enzyme generally increases under heavy metal stress [4], but in susceptible plants or from conditionally pure habitats, this enzyme are inhibited [2].…”

Normal oxygen metabolism is an endogenous source of reactive oxygen species (ROS). The source of ROS are also many environmental factors including heavy metals. In certain concentration range, the presence of ROS is necessary to maintain proper cell function. Thus, cells have many mechanisms, which role is focused on maintaining a constant concentration of ROS. Imbalance between the formation of ROS and action of a protective antioxidant system leads to oxidative stress. This may results with a damage to the structure of proteins, lipids and nucleic acids, which in turn can lead to disturbances in the functioning of the cell and even to the death. The aim of the study was to evaluate the effect of copper ions on the metabolic activity of garden cress Lepidium sativum L. The action of copper ions with different concentrations was treated seeds. After four, six and eight days after planting in the leaves of garden cress were determined the specific activity of guaiacol peroxidase (GPOX), lipid peroxidation and protein content. Additionally intake of copper ions was determined using adsorption spectrometry technique. The results revealed that the applied doses of copper ions affected the activity of guaiacol peroxidase. The highest enzyme activity was found in plant material, which was treated with dose of copper ions 1000 mg/dm 3 regardless of day. In the same samples the lowest level of lipid peroxidation was found. The highest concentrations of total proteins was found in samples treated with the highest dose of copper ions. The copper content in the tested plant material is correlated with the applied dose of copper ions. Our results indicate reliable correlations between copper content and values of oxidative stress biomarkers in plant tissues.

The aim of this study is to evaluate the effects of the effluent of Elazig Municipality Wastewater Treatment Plant on the oxidative defense capacity of aquatic plants (Lemna minor L. and Lemna gibba L.). For this purpose, malondialdehyde (MDA), glutathione (GSH), oxidized glutathione (GSSG), vitamin A (retinol), vitamin E (α-tocopherol), and vitamin C (Ascorbic acid) levels were determined by the HPLC (high performance liquid chromatography) in the control groups and the groups adapting to reactors fed with discharge water. The depletion of vitamins (A, E, and C), decrease of GSH/GSSG ratio, and increase of MDA that reflect a precarious state of the cell in L. minor L. and L. gibba L. were observed after exposure to wastewater. It can be suggested that the selected biomarkers are useful in understanding the biochemical mechanisms of the secondary effluents from wastewater treatment plant in L. minor L. and L. gibba L. as early warning indicators.

A hydroponic experiment was conducted to investigate the effects of oxalic acid (OA) on arsenic (As) uptake and the physiological responses of Hydrilla verticillata exposed to 3 mg L of As in different forms. Plant As(III) uptake was significantly increased by 200-2000 µg L OA. However, an increase of As(V) uptake was only shown with 1000 µg L OA, and no significant difference was observed with dimethylarsinate treatment. Peroxidase and catalase activities, and the contents of photosynthetic pigments, soluble sugar and proline, were significantly increased by 1000 µg L OA during As(III) treatment. Superoxide dismutase and proline were also increased significantly by 1000 µg L OA when plants were exposed to As(V). In DMA treatment, proline was significantly increased by 500 µg L OA. Therefore, As-induced oxidative stress is relieved by OA, but it depends on OA concentration and the form of As. Our results may be useful for the phytoremediation of waste water containing As and OA.
