“…It might have happened because the roots are the primary source that comes in contact with the heavy metal contamination ( Ganesh et al, 2008 ; Basit et al, 2022 ). First, plants uptake Cr contents through the nutrient solution, it accumulates inside roots, and it may decrease the polysaccharide inside the roots cell wall which further causes cellular elongation restriction and later-stage plant growth and development damage ( Alam et al, 2021 , Terzi and Yıldız, 2021 , Ao et al, 2022 ). The reduction in plant height was clearer in cultivar HV10, and NV7 ( Table 3 , Table 4 ).…”

“…It is also reported that the reduction in plant biomass and growth attributes are also directly related to the impairment in the photosynthetic system ( Ulhassan et al, 2019a , Ao et al, 2022 , Kharbech et al, 2022 ). As expected, the Cr stress caused the reduction in chlorophyll contents (chlorophyll-a, b, a + b, and carotenoids) of all rice cultivars ( Fig.…”

“…The exposure of chickpea plants to Cr declined RWC, a stress indicator ( Pandian et al, 2020 ). A significant decline in RWC has been reported in various crop such as rice ( Pandey et al, 2019 ; Yang et al, 2021 ) and oilseed rape ( Gill et al, 2015 ) under Cr VI stress, which is possibly attributed to the higher assimilation rate of Cr ions in roots compared to shoots, which protects shoots from high Cr accumulations by promoting optimum water intake in aerial parts ( Ao et al, 2022 ). Similar relationships have been observed with heavy metal stress in various crop plants ( Bali et al, 2019 ; Pandian et al, 2020 ).…”

Extensive use of chromium (Cr) in anthropogenic activities leads to Cr toxicity in plants causing serious threat to the environment. Cr toxicity impairs plant growth, development, and metabolism. In the present study, we explored the effect of NaHS [a hydrogen sulfide; (H2S), donor] and silicon (Si), alone or in combination, on two chickpea (Cicer arietinum) varieties (Pusa 2085 and Pusa Green 112), in pot conditions under Cr stress. Cr stress increased accumulation of Cr reduction of the plasma membrane (PM) H+-ATPase activity and decreased in photosynthetic pigments, essential minerals, relative water contents (RWC), and enzymatic and non-enzymatic antioxidants in both the varieties. Exogenous application of NaHS and Si on plants exposed to Cr stress mitigated the effect of Cr and enhanced the physiological and biochemical parameters by reducing Cr accumulation and oxidative stress in roots and leaves. The interactive effects of NaHS and Si showed a highly significant and positive correlation with PM H+-ATPase activity, photosynthetic pigments, essential minerals, RWC, proline content, and enzymatic antioxidant activities (catalase, peroxidase, ascorbate peroxidase, dehydroascorbate reductase, superoxide dismutase, and monodehydroascorbate reductase). A similar trend was observed for non-enzymatic antioxidant activities (ascorbic acid, glutathione, oxidized glutathione, and dehydroascorbic acid level) in leaves while oxidative damage in roots and leaves showed a negative correlation. Exogenous application of NaHS + Si could enhance Cr stress tolerance in chickpea and field studies are warranted for assessing crop yield under Cr-affected area.

“…Chromium is a non-essential element for plants and, especially in the hexavalent form, it can be highly toxic, impairing plant growth and development (Shanker et al 2005). Plants do not possess specific carriers nor channels for Cr uptake but, especially when growing in Cr-rich substrates, they can absorb it through the transport proteins typically involved in the acquisition of mineral nutrients (Shanker et al 2005;Ao et al 2022). As widely recognized, Cr can be taken up both as Cr(III), through a passive mechanism, and as Cr(VI), exploiting the carrier system of sulfate or phosphate, due to the chemical structure similarity of these anions (Skeffington et al 1976;Smith et al 1989;Zayed et al 1998;Hamilton et al 2020;Ao et al 2022).…”

Fire events can modify the distribution and speciation of potentially toxic elements (PTEs) in soil, especially if they are associated to organic matter (OM). In fact, OM can undergo substantial structural modifications at high temperatures, up to the complete mineralization. The present study aims to investigate the changes of PTEs’ bioavailability to durum wheat (Triticum durum Desf.) plants after simulating fire events (up to 300 °C and 500 °C) in an agricultural soil polluted by Cr, Zn, Cu, and Pb. The PTEs’ uptake and allocation in plant tissues were assessed using the RHIZOtest system. After the fire simulations, no evident risk of accumulation and translocation in plants was observed for Zn, Pb, and Cu. Conversely, a high accumulation in roots and a significant translocation to shoots were observed for Cr, which reached concentrations of 829 mg kg−1 in roots and 52 mg kg−1 in shoots at 500 °C. Additional experimental evidence suggested that Cr was taken up by plants grown on heated soils as Cr(VI). Once acquired by roots, only a small part of Cr (up to 6%) was translocated to shoots where it was likely present as mobile forms, as evidenced by micro X-ray fluorescence (µ-XRF) analyses. Overall, the results obtained provide evidence that the high temperatures occurring during fire events can increase the mobility and bioavailability of certain PTEs transforming apparently safe environments into potentially dangerous sources of pollution. These processes can ultimately affect the human health through the food chain transfer of PTEs or their migration into surface water and groundwater.
