“…However, the soluble protein content in leaves was decreased after Cd exposure. Similar results were found by Molnárová and Fargašová [32] in Sinapis alba and Hordeum vulgare plants. The observed decline in soluble protein could be responsible for the decrease in antioxidant enzyme activity.…”

Hydroponic experiments were conducted using cadmium (Cd)-sensitive (cv Guiyan 1) and Cd-tolerant (Yunyan 2) tobacco cultivars to evaluate cultivar differences in response to Cd toxicity in the presence of selenium (Se). The results showed that addition of 3 µM Se in 50 µM Cd solution markedly reduced Cd accumulation in plants, alleviated Cd-induced growth inhibition, and increased nitrogen and chlorophyll contents as well as photosynthetic performance (i.e., net photosynthetic rate, stomatal conductance, and transpiration rate). External Se dramatically depressed Cd-induced O2 (•-) , H2 O2 , and malondialdehyde accumulation, especially in the sensitive cultivar. Selenium significantly elevated Cd-depressed activities of superoxide dismutase, peroxidase, catalase, ascorbate peroxidase, glutathione-peroxidase, and glutathione reductase in the both cultivars after 7-d treatments. Meanwhile, Se counteracted Cd-induced alterations in certain nutrient elements; for example, it significantly increased Zn and Ca concentrations and reduced Mg concentration in both cultivars. Furthermore, Se significantly elevated Cd-depressed H(+) -K(+) -adenosine triphosphatase (ATPase), Na(+) -K(+) -ATPase, and Ca(2+) -Mg(2+) -ATPase activities. The beneficial effect of Se under Cd stress may be related mainly to the increased ATPase activity and reduced Cd uptake and reactive oxygen species accumulation, thus reducing the negative consequences of oxidative stress caused by Cd toxicity.

“…This observation stays in agreement with other studies that proved the particularly high accumulation of contaminants in early stages of plant growth in plant roots and a substantial reduction of root elongation compared to the shoots [29][30]. However, the results obtained in the case of soil solutions acquired in the first two days from BL-treated soil No.…”

Soil solutions were collected from soils contaminated differently by the emissions from a copper smelter and incubated with beech litter. Five times in 30 days of incubation, soil solutions were acquired with MacroRhizon samplers and examined using the chemometric approach and two ecotoxicological assays: Microtox with Vibrio fischeri bacteria and Phytotoxkit with Sinapis alba seeds. Copper speciation in soil solutions was modeled in the MinteQ program. Application of beech litter to soils resulted in a considerable increase of copper solubility. The toxicity of soil solutions was associated with total copper concentrations in solutions, copper speciation, and pH values. The toxicity measured by the Phytotoxkit test in soil solutions collected from non-amended soils was higher than that measured in Microtox, and was attributed to high concentrations of copper organic complexes in solutions. The application of beech litter, rich in dissolved organic carbon DOC, resulted in a radical increase of soil solution toxicity to both indicating organisms. This effect, particularly well expressed in the case of V. fischeri, was apparently caused by a decrease in pH and associated increase of total Cu concentrations in solutions.

“…The minimum of 2 g of soil dried until constant weight were used for mineralization following the same procedure as the dry weight of leaves. After cooling, mineralized samples were diluted up to 25 ml with redistilled water and metals determination by galvanostatic-dissolved chronopotenciometry on an EcaFlow 150 GLP (Istran, Slovak Republic) [25]. This electrochemical method is comparable to the atomic absorption spectrophotometric (AAS) method in precision, accuracy, and sensitivity of the measured results (concentration range and reproducibility of selected (semi)metals in Table 3 originate from application lists of the Istran Company).…”
