“…These results indicated that sunflower can grow on soil contaminated with Cr, Cu, and Zn, and it can also accumulate large amounts of Zn [22]. Sunflower is relatively resistant to high Zn soil concentrations; therefore, it can be used for Zn phytoextraction of moderately contaminated soil (approximately 200 mg Zn kg −1 soil) [23].…”

The water aquifers of the regions of Asopos River in Viotia and Messapia in Evia (Greece) have been contaminated with hexavalent chromium (Cr (VI)) and bivalent nickel (Ni (II)). Given that these areas are the two biggest tuber producing regions of Greece, in our previous work, the cross-contamination of the food chain with these two heavy metals was quantified. In the present study, the potential of sunflower (Helianthus annuus) cultivation in these regions is evaluated. The scope of our study was to investigate the uptake of chromium and nickel by sunflower, in a greenhouse experiment. The study included two cultivation periods of plants in six irrigation lines with different levels of Cr (VI) and Ni (II) ranging from 0 μg/L (control) to 10,000 μg/L. In all plant parts, statistically significant increased levels of Cr (VI) and Ni (II) were found when compared to control ones. Also, a positive correlation, both for Cr and Ni, between levels of heavy metals in irrigation water and plants was observed. Following European Food Safety Authority recommendations, the obtained oil was evaluated as safe for consumption, therefore, sunflower cultivation could be a valid bioremediation solution for the Asopos and Messapia regions.

The research has been carried out in recent years on the possibility to use eggshells as a catalyst in the processes of biodiesel production [1,2], lactose isomerisation [3], dimethyl carbonate synthesis [4] and as a sorbent in water treatment processes [5,6], immobilisation of heavy metals in soils [7,8], CO 2 binding (removing) [9].…”

Studies of the efficiency of Ni, Cu and Cd cations removal from water solutions were carried out, with the use of clay limestone, hen eggshells from eggs for consumption and hen eggshells after hatching, which main element is calcium carbonate. Hen eggshells are a waste product, which can be used as a substitute of clay limestone in removing heavy metals from wet flue gas desulphurisation installation. Mixed solutions of Ni, Cu and Cd were used in the research, with the composition similar to the waste water from wet flue gas desulphurisation installation: Ni (0.009-0.053 mmol/dm3), Cu (0.008-0.057 mmol/dm3) and Cd (0.003-0.008 mmol/dm3). The metals were determined by flame atomic absorption spectrophotometry (F-AAS). Kinetics of the process was analysed and equilibrium parameters were estimated, taking into consideration changes of the solutions pH during the process duration. It was demonstrated that the dominating mechanism of cations removal is their binding in hydroxides and carbonates. The studies demonstrated comparable characteristics of hen eggshells versus clay limestone, in the context of their application in removal of heavy metal cations from solutions.

“…Phytoextraction is recommended as one option for reducing toxic metal content, as the technology is perceived to be ecofriendly, effective, and affordable (Shaheen and Rinklebe, 2015;Antoniadis et al, 2017). Phytoextraction heavy metals had received increasing attention in recent years as an alternative to physical and chemical methods of decontamination in which heavy metals accumulating plants and appropriate soil amendments were used to transport and concentrate heavy metals from the soil into the aboveground shoots (Nowack et al, 2006;Vamerali et al, 2012).…”

A pot experiments was carried out in the greenhouse of Faculty of Agriculture Cairo University during the two successive winter seasons (2015-2016 and 2016-2017) to evaluate the potential of flax plants (Linum usitatissimum L.) as a Cd tolerant and accumulator for polluted soils. The experiment was laid out in a split-plot design with a randomized-complete design in three replicates. Surface sandy loam soil samples (0-20 cm) were collected from Abou-Rawash area, which received sewage sludge and sewage effluent for long time (about 20 years).Three levels of soil Cd (initial 3.13), and two artificial ones 50 and 75mg kg-1 soil, were prepared using CdCl 2 solution by wet and dry process for three months. The chemical (EDTA) and biological (AMF and Thiobacillus) treatments were allocated to sub plots. Each sub plot consisted of pots each containing 10kg soil and 100 flax plants. The results showed that by increasing soil cadmium levels, the flax plant dry weight (roots, stem and leaves) significantly decreased. Under different levels of soil Cd, the chemical and biological treatments recorded variable changes in flax plant dry weight. The highest increases in dry weight was recorded with AMF treatment (5.63 and 8.50% in 1 st and 2 nd seasons, respectively, with an average of 7.06%) compared with the control (initial).However, cadmium contents in the different parts of flax plant increased with increasing soil cadmium levels. The highest Cd concentration in flax roots, stem and leaves recorded in EDTA treatment which lead to increases of 1.73, 2.11 and 1.88 folds in roots, stem and leaves, respectively, compared with untreated soil at 75 µg Cd g-1 soil. The uptake of Cd by flax substantially affected by both levels of Cd in soil and different soil treatments. The highest Cd uptake was found in 75 µg g-1 soil level followed by 50µg g-1 and the lowest in 3.13 µg g-1 soil. Flax was uptake and accumulate cadmium from the soil with distributing evenly throughout plants (roots < stem < leaves). Both EDTA and AMF treatments recorded the highest phytoextraction of Cd from contaminated soil. Finally, the obtained results suggest that, flax plant can be considered as a Cd tolerant which can accumulate Cd, especially, with mycorrhiza fungi and EDTA treatments but could not be considered a hyperaccumulator of Cd from polluted soils.
