“…Suggestion of World Health Organisation (WHO) indicated that the chromium concentration in plants growing in unpolluted soil should not exceed 0.19 mg·kg −1 [21]. Other authors reported [10] that in normal conditions, chromium concentration in plants is less than 1 µg·g…”

“…Its commonly existing forms are trivalent and hexavalent chromium [2,3]. In oxidized Cr (VI) form, chromium is highly soluble in water, and therefore mobile, whereas the reduced Cr (III) form is almost insoluble in water and thus immobile [4,9,10]. Hexavalent chromium is very toxic, and it can be an inhaled carcinogen, poisonous to humans and other mammals, whereas trivalent chromium is an essential nutrient as mineral supplement [1,3,9,11].…”

“…One of reasons is that this element is constantly considered as a "local source" contaminant, whilst the second is that the dominant naturally occurring form of chromium, Cr 2 O 3 , is known essentially immobile and non-toxic in the environment [10].…”

“…Many organic molecules are exposed to severe damage by free radicals after high accumulation of heavy metals in plants (Alfonso and Puppo, 2009;Joshi et al, 2005). Formation of ROS in cells is associated with the development of many pathological states (e. g. reduced root elongation, seed germination, signaling imbalance) (Bini et al, 2008;Wahsha and Al-Jassabi, 2009). This has contributed to the creation of the oxidative stress concept; in this view, ROS are unavoidable toxic products of O 2 metabolism, and aerobic organisms have evolved antioxidant defenses to protect against this toxicity (Alfonso and Puppo, 2009).…”

Contamination by heavy metals in soils may strongly affect the environmental quality. Lipid peroxidation caused by heavy metals in plants was investigated as a relevant bioassay of toxicity. Soils and wild plants (dandelion and willow) were collected from an abandoned mine area in northeast Italy, and the concentration of different heavy metals (Ni, Cr, Cu, Pb, Zn, Fe and Mn) were measured and analyzed. Soils affected by mining activities presented total Zn, Cu, and Pb concentrations (2566, 3975, 20,815 mg kg −1 respectively) above toxic thresholds, and 58% for Fe. Heavy metal-induced oxidative stress was evidenced by the generation of reactive radicals, followed by an increase in malondialdehyde (MDA) production up to 41.64 μM in willow leaves. We found that MDA concentration in plant tissues differed significantly among species and plant organs. The higher concentration of metal in soil corresponded with the higher concentration of MDA in the plant. The combined results of metal concentration, MDA content and translocation coefficients in plants show that the investigated plants are rather highly tolerant towards environmental pollution. This suggests that they could be useful in phytoremediation of metal contaminated sites.

“…For this reason, metal contamination of soils and plants becomes a main issue in agricultural production. The recognition of the contamination source is also an important issue; it can be natural, arising from trace metals in rocks (Kabata-Pendias and Mukherjee 2007;Bonifacio et al 2010;Gonnelli and Renella 2013), and/or anthropogenic, as industrial or agriculture activities, i.e., using chemicals, fertilizers and pesticides, sewage sludge, and irrigation with wastewater (Adriano 2001;Bini et al 2008). In viticulture, treatments with manure and/or fungicides may cause contamination of soils and plants.…”

Concentrations of potentially toxic elements and soil environmental quality evaluation of a typical Prosecco vineyard of the Veneto region (NE Italy)

Purpose The aim of this work was to assess the concentrations of potentially toxic elements and to evaluate the soil quality of a typical Prosecco Denomination of Controlled and Guaranteed Origin vineyard of the Veneto region, NE Italy. Materials and methods Soil samples and leaves of Taraxacum officinale and Vitis vinifera were collected during spring-summer 2014. Element determination (Al, Cd, Cr, Cu, Fe, Mg, Mn, Ni, P, Pb, V, and Zn) were performed with ICP-OES after microwave digestion of samples. Soil quality was assessed via the biological soil quality (BSQ-ar) index. Lipid peroxidation test was performed to evaluate the vegetation oxidative stress, based on malondialdehyde (MDA) content via spectrophotometer. Results and discussion High concentrations of Al, Mg, and P were identified in soil, while high contents of Al, Cu, Fe, and Zn were found in V. vinifera leaves. The high concentrations in soil are probably due to agricultural activities, whereas those in leaves are probably due to atmospheric deposition and repeated use of foliar sprays in viticulture. The bioconcentration factor showed an effective transport of Cu, P, and Zn, from soil to leaf. The BSQ-ar values registered were similar to those obtained in preserved soils; hence, the biological class (VI) of these soils is high. The MDA content in T. officinale and V. vinifera leaves was below the reference value for T. officinale (2.9 ± 0.2 μM), suggesting that the metal content did not stress the vegetation in the investigated site. Conclusions The MDA value for V. vinifera (1.1 ± 0.7 μM) could be adopted as another control value for soil quality, which in our case is of Bgood quality.^Moreover, our results suggest that high concentrations of elements detected in the analyzed samples do not influence negatively the quality of soil, but a better agronomic management could improve soil quality in the studied area.
