“…23.1 ± 3 g and 5.1 ± 1.5 g for cladodes initially planted vertically and horizontally, respectively, whereas the root weight of blanks for the two modes of cultivation reached 37.6 ± 2.8 g and 5.8 ± 0.9g, respectively. The lower amount of biomass found in contaminated Ofi after 4 months of cultivation might be related to the effects of Pb on the biochemical and physiological metabolisms as described in previous studies (Onder and Dursun, 2006;Sharma and Dubey, 2005;Zeneli et al, 2013). However, the mere presence of fluorapatite particles on the cladode surface, e.g.…”

The contamination of edible leafy vegetables by atmospheric heavy metal-bearing particles is a major issue in environmental toxicology. In this study, the uptake of lead by cladodes of Opuntia ficus-indica (Ofi), traditionally used in Mexican cuisine and in livestock fodder, is investigated after a 4-months exposure of either cladodes or roots to synthetic Pb-fluorapatite particles. Atomic Absorption Spectroscopy (AAS) for the quantitative analysis of Pb levels, Scanning Electron Microscopy coupled with Energy Dispersive X-Ray Spectroscopy (SEM-EDX) for the examination of the cladode surface and fate of particles, and Micro-X-ray fluorescence (μXRF) measurements for elemental mapping of Pb in cladodes, were used. The results evidence that foliar contamination may be a major pathway for the transfer of Pb within Ofi cladodes. The stomata, areoles, and cuticle of cladode surface, play an obvious role in the retention and the incorporation of lead-bearing apatite, thus revealing the hazard of eating contaminated cladodes. The possibility of using series of successive cladodes for biomonitoring the atmospheric pollution in arid and semi-arid regions is also rapidly discussed.

“…Fe is especially involved in oxidation and reduction processes, reduction of nitrite and sulfate, and is predominantly included in photosynthesis. 24 Shortage of Fe is a common nutritional disorder in many plants, resulting in poor yields and decreased nutritional quality. 25 Cu concentration occurred in a range from 5.09 mg/kg to 28.66 mg/kg, the higher end of which was higher than the permissible level of Cu in medicinal plants suggested by WHO (10 mg/kg).…”

Plants grown under contaminated conditions exhibit differences in metal absorption, accumulation, and transportation, and these differences are seen in different plant parts. Metal content in the soil and bark samples collected next to the Sitnica river, which passes through the industrial area of thermal power plants in Kosovo, was measured by inductively coupled plasma optical emission spectrometry. The total metal concentration in willow bark collected from the polluted area of Obilic, Kosovo, ranged 5260–22,280 mg/kg for calcium (Ca), 840–1680 mg/kg for magnesium (Mg), 66.79–910.75 mg/kg for iron (Fe), 5.09–28.66 mg/kg for copper (Cu), 56.39–140.94 mg/kg for zinc (Zn), 19.68–392.75 mg/kg for manganese (Mn), 6.49–10.09 mg/kg for nickel (Ni), 0.10–4.49 mg/kg for cadmium (Cd), 0.85–1.89 mg/kg for chromium (Cr), and 67.79–94.77 mg/kg for aluminum (Al). Data analysis indicated that correlation between trace elements in the soil and willow bark samples varied with the highest observed in Ni(s)/Zn(p) and Fe(s)/Ca(p) followed by Fe(s)/Mg(p), Al(s)/Ca(p), Cr(s)/Mg(p), Cr(s)/Cu(p), Ni(s)/Ni(p), Cu(s)/Ca(p), and Cu(s)/Zn(p). Correlations among trace elements within willow bark samples varied. The correlation between Cr and Al concentration was the highest, followed by that between Ni and Al. A significantly strong correlation was observed between Al and Fe, Ni and Cr, Cr and Fe, Ni and Fe, and Ca and Mg. The highest transfer factor was established in Zn, followed by Cu > Ni > Cr > Al > Fe.

“…Considerable studies in recent years have established the important connection between air, water, soil, and plant pollution and toxic element accumulation. The zone around the Kosovo thermal power plants (KTPPs), energy producers, is the greatest concern of the Republic of Kosovo in the context of environmental pollution [14]. From a pollution point of view, the most important activities are those in coal (lignite) mines and the production of electric power.…”

“…Plants are subjected to a variety of stressors in the natural world, all of which contribute to the over-production of reactive oxygen species [14]. Heavy metals, as abiotic stress factors, also initiate various processes in plants, some of which may even be harmful to their anatomical, morphological, physiological, and biochemical function, causing the production of reactive oxygen species and oxidative stress in plants.…”

In this study, we analyzed and compared the concentrations of selected metals/metalloids and the antioxidant response of Salix alba L. (white willow) bark in the highly polluted area around the Kosovo A and B thermal power plants. The antioxidant capacity of Salix alba bark was evaluated in terms of the total phenolics, flavonoids, chlorophylls, and carotenoids, while the metal content in the soil and willow bark was analyzed by ICP-OES (inductively coupled plasma optical emission spectroscopy). For total antioxidant level assessment, FRAP, DPPH, and CUPRAC assays were conducted. The mean concentrations of selected elements in soil and willow dry mass range from 15,698.4 mg kg−1 dry mass (soil) to 371.1 mg kg−1 (willow bark) for Al; 37.676 mg kg−1 (soil) to <2 ppb (willow bark) for As; 14.8 mg kg−1 (soil) to 0.62 mg kg−1 (willow bark) for Cd; 24.2 mg kg−1 (soil) to 1.2 mg kg−1 (willow bark) for Cr; 58.8 mg kg−1 (soil) to 9.1 mg kg−1 (willow bark) for Cu; 16,975.68 mg kg−1 (soil) to 385.4 mg kg−1 (willow bark) for Fe; 95.0 mg kg−1 (soil) to 7.9 mg kg−1 (willow bark) for Ni; 185.2 mg kg−1 (soil) to <1 ppb (willow bark) for Pb; and 226.7 mg kg−1 (soil) to 87.7 mg kg−1 (willow bark) for Zn. Additionally, the Salix alba bark samples presented mean values of 12,191.6 mg kg−1 for Ca, 1306.0 mg kg−1 for Mg, and 123.1363 mg kg−1 for Mn. The mean phenolic content was 39.292 mg GAE g−1 DW, being 28.222 mg CE g−1 DW for flavonoids, 38.099 mg g−1 FW for CHLa, 49.240 mg g−1 FW for CHLb, and 94.976 mg g−1 FW for CAR. The results of this study indicate that the bark of Salix alba contains significant amounts of phenolic compounds, and strong positive and moderate negative correlations are revealed between total phenolic compounds and iron, and total phenolics and nickel and manganese, respectively.
