“…According to Rashed [43] dicotyledon species, such as Vigna angularis, uptake and transport more Cr to shoots than monocotyledons plants, such as maize, due to differences in the rooting patterns, transpiration rates and metabolism between these two groups of plants while Cui et al [46] oppositely found that Amaranthus dubius tolerated high Cr(VI) concentrations by accumulating and transferring them to aerial parts. The outcome of this study also compares to the reported findings by Oliveira et al [47], which found that an increase in Cr concentration in the leaves may be related to higher soil Cr concentration from the spiked soil and therefore, the metal was bioaccumulated from the roots to the leaves. Lower accumulation of Cr in leaves than in roots can be related to the conservation of photosynthesis processes from toxic levels of trace elements as well, according to Zojaji et al [48].…”

This study reports on the assessment of the growth potential of five edible vegetables, which were grown in Cr(VI) spiked soils. The vegetable plants that were used in this study were Vigna angularis, Cicer arietinum, Spinacia oleracea, Amaranthus dubius Thell and Phaseolus vulgaris. Dried ground samples from roots, stems and leaves were analysed for various oxidation states of Cr. The daily intake of chromium, hazard quotient (HQ) and hazard index (HI) methods were employed to assess the potential human health risks posed by these Cr oxidation states through vegetable consumption. The results showed that Vigna angularis was the only vegetable that germinated in highly concentrated Cr(VI) in the simulated soil (456 mg/kg). The highest total chromium (ChT) bioaccumulated in the roots was found in Phaseolus vulgaris at 0.8. The highest ChT translocation factor in the stem was that of Cicer arietinum and Vigna angularis at 0.30. The same plants translocated the highest ChT to the leaf at 0.7. A child or an adult consuming such contaminated Cicer arietinum vegetables were likely to take in between 508 and 785 mg/day of ChT, which are above the World Health Organisation guidelines of 220 and 340 mg/day, respectively. The highest HQ was found in Cicer arietinum at 8.7 and 13.4 for adults and children, respectively. The same species of plants also had high HI at 17.4 and 27.2 for adults and children, respectively. This indicated that consumers of the edible vegetables grown in Cr(VI) rich soils may be exposed to health risks, and the children were more likely to be vulnerable to these adverse effects than the adults.

This study reports on the assessment of the growth potential of five edible vegetables which were grown in Cr (VI) spiked soils. The vegetable plants that were used in this study were Vigna angularis, Cicer arietinum, Spinacia oleracea, Amaranthus dubius Thell and Phaseolus vulgaris. Dried ground samples from roots, stems and leaves were analysed for various oxidation states of Cr. The daily intake of chromium (DIC), hazard quotient (HQ) and hazard index (HI) methods were employed to assess the potential human health risks posed by these Cr oxidation states through vegetable consumption. The results showed that Vigna angularis was the only vegetable that germinated in highly concentrated Cr (VI) in the simulated soil (456 mg/kg). The highest bioaccumulation factor of CrT in the roots was found in Cicer arietinum at 3.5 ± 0.51 mg/kg DW. The highest translocation factor in stem was that of Cicer arietinum and Vigna angularis at 1.0 ± 0.00, while Cicer arietinum and Spinacia oleracea translocated highest Cr to the leaf at 2.1 ± 0.21. A child or an adult consuming such contaminated Cicer arietinum were likely to take in between 508 -785 mg/kg/day of total Cr which were above the World Health Organisation guidelines of 220 and 340 mg/kg/day, respectively. The highest HQ was found in Cicer arietinum at 8.7 and 13.4 for adults and children, respectively. The same species of plants had also high HI at 17.4 and 27.2 for adults and children respectively. This indicated that consumers of the edible vegetables grown in Cr (VI) rich soil may be exposed to health risks and the children were more likely to be vulnerable to these adverse effects than the adult.

“…2). Increases in organic carbon can improve soil conditions (Gianello et al 2011;Oliveira et al 2015), even though there is a lack of studies on ILS due to heavy metal contents and environmental risks. High concentration of organic carbon (7.3%) and neutralizing power (49%) in ILS can contribute to complexation and unavailability of metals to the soil micro-biota and plants, due to the increase in pH dependent electrical charges and negative charges of organic matter (OM), hence, increasing the metal cations connections (Sposito 2008).…”

“…Leather and Footwear Industry has significant importance for the economy of Rio Grande do Sul (RS-Southernmost Brazilian state). These activities generate many hazardous materials due to the high concentration of chromium in the wastes from leather treatment; although some of those wastes may have conditioner, fertilizer, and corrective properties to the soil (Gianello et al 2011;Oliveira et al 2015). Some of the elements most found in the tanning industry sludge are N, P, K, S, Ca, Mg, Zn, Fe, Cu, Mn, Cr, and Na (Silva et al 2010;Gianello et al 2011).…”

“…Some studies have proved that the sludge can stimulate microbial communities in edaphic environments (Nakatani et al 2012;Silva et al 2014), and plants (Silva et al 2010;Patel et al 2015;Nessa et al 2016) due to the pH regulation and the increment of nutrients and organic carbon. Moreover, the amendment of wastes with high concentration of heavy metals may cause toxicological damage to soil systems (Celary and Sobik-Szołtysek 2014;Oliveira et al 2015). Regarding sludge from leachate treatment plant (LTP), its characteristics depend on the type of waste disposed in the landfill cells (de Andrade et al 2016).…”

Purpose The purpose of this work was to evaluate the impacts of the amendment of industrial landfill sludge (ILS) in two different soils with cultivation of sunflower and sorghum plants. Methods The plants grew in two types of soils (Typic Paleudult-TP, and Grossarenic Hapludult-GH) with different doses of ILS (0, 2, 5, 10, and 20 Mg ha −1). The evaluation of the pH, electrical conductivity, available concentrations of P, K, Ca, Mg, and Na, and the hydrolysis of FDA in the soils were tested. The height and dry mass of both plants were measured, as well as the stem diameter of the sunflower. The total concentration of Cu, Cd, Cr, and Pb was evaluated in the plants and soils, in addition to the translocation factor of those in the plants. Results The amendment of ILS in the soils was efficient to increase the pH and macronutrients, as to increase the biomass production. The largest production occurred with 10 Mg ha −1 , and the highest dose (20 Mg ha −1) had negative effects in all treatments. Both plants had low accumulation of Cu, Cd, and Pb in their tissues. Cr increased in the roots of sunflower plants (especially in the TP soil) without translocation to the shoots. Conclusions The amendment of ILS in soils is an alternative to disposal with benefits to plants and soil quality. TP soil presented better results, being more secure to receive the sludge due to its higher content of clay when compared to the GH soil.
