“…In the seedling stage (30 days after transplantation), blooming stage (79 days after transplantation) and fruiting stage (122 days after transplantation), 6 plants were randomly collected in each treatment, washed with Na 2 -EDTA several times to remove ions attached to the surface, then washed with deionized water and dried at 75 • C to constant weight [22]. The whole plant sample was divided into roots, stems and leaves in the seedling stage or roots, stems, leaves and flowers in the blooming and fruiting stages.…”

Phytoremediation with hyperaccumulator plants has been recognized as a potential way for the clearing of cadmium (Cd)-contaminated soil. In this study, hyperaccumulator Tagetes patula was treated with seven concentrations of Cd, ranging from 0 to 300 mg kg−1. The Cd enrichment and nutrient contents in different organs during different growth phases were investigated. Under Cd concentrations ≤75 mg kg-1, the morphological growth of T. patula did not change significantly regardless of growth stage. However, when Cd concentration exceeded 150 mg kg−1, the morphological growth was remarkedly inhibited. The root/shoot ratio remained unchanged except for at 300 mg kg−1. In addition, Cd negatively influenced the flowering process at the concentration of 300 mg kg−1. Cd content increased significantly in Cd-treated plants. Nitrogen absorption was increased under Cd treatments, and phosphorus content was also increased under concentration ≤150 mg·kg−1. However, the potassium content in the flower was decreased under 300 mg kg−1. Furthermore, the contents of H2O2, O2− and malondialdehyde were increased during the seedling phase, especially when Cd concentration was ≥150 mg kg−1. In summary, T. patula showed a strong ability to tolerate Cd, and such ability might be explained by nutrient absorption and reactive oxygen clearness.

“…Heavy metals can be present in soil in the form of dissolved free ions, dissolved complexes with inorganic anions and organic ligands, in the compound of exchange complexes on clayey minerals and organic matter, which are held by electrostatic forces, in the form of organic-mineral heteropolar, complex-heteropolar salts, sorption complexes, etc. (Ferro et al, 2021;Zhang et al, 2021).…”

The balance between anti- and prooxidants in animal organisms in general and in each cell in particular is responsible for the regulation of many metabolic processes that provide immunocompetence, growth, development and protection of animals from oxidative stress, related to inflow of cadmium and plumbum. Therefore, the objective of our study was the influence of a liposomal drug based on interferon and milk thistle (Silybum marianum (L.) Gaertn.) on the antioxidative status of the organism of bulls in the conditions of cadmium and plumbum loading. The experiments were performed on six-months-old Black Motley dairy cattle. The fodders in the farm were determined to contain high levels of plumbum and cadmium. The liposomal drug Lipointersyl inhibited the lipid peroxidation processes in the bulls. The drug components promoted the decrease in the level of intermediate and end products of lipid peroxidation, in particular 22% decrease in the level of diene conjugates and 20% decrease in TBA-active products. Intramuscular injection of the liposomal drug to bulls of the experimental group strengthened the antioxidant protection of their organism. On the 30th day of the experiment, blood from experimental group animals was seen to have a 9.8% increase in reduced glutathione. Assay of the enzymatic link of the glutathione system revealed that the activity of glutathione peroxidase and glutathione reductase in the blood of the animals that had been injected the liposomal drug Lipointensyl had increased by 24.0% and 27.7% respectively by the 30th day of the experiment. The experiments conducted on young cattle demonstrated that intermuscularly injected the Lipointensyl liposomal drug – against the background of cadmium and plumbum loading – promoted the activation of the glutathione system of antioxidant protection as a result of increase in the activity of its enzymatic and non-enzymatic links. The study of catalase and superoxide dismutase activities revealed that on the 30th and 40th days of the experiment, the activity of those enzymes varied within the physiological norms. Therefore, the analyzed Silybum marianum-based liposomal drug has antioxidant properties, it is recommended for young cattle in the conditions of contamination with heavy metals in order to prevent the development of oxidative stress.
