There are more natural and more cost-effective alternatives to economically over costing physical and chemical remediation of polluted agricultural soils. Heavy metals that exert a significant toxicity on the organisms in the environment are one of the primary dangerous materials. In the elimination of heavy metal toxicity in the soils, phytoremediation method is used as a new technology. In this study, the usability of corn (Zea mays L.) in the phytoremediation of hexavalent chromiumcontaminated soil. Moreover, the hyperaccumulator ability of the corn for Cr +6 heavy metal was evaluated. In order to increase the solubility of chromium heavy metal in the soil different amounts of chelator (EDTA) were applied to the soils. The study was conducted according to the random blocks experimental design under controlled conditions with totally 18 pots of 3 replicates of control and 5 different chelate doses (0, 10, 20, 40, 80 mmol/kg). The soils in the pots were incubated with 30 mg/kg Cr +6 as Chromium (VI) oxide (Sigma-Aldrich No: 232653) for 30 days. During the sowing of the corn seeds 150 mg/kg N, 100 mg/kgP 2 O 5 , and 125 mg/kg K 2 O were applied to the pots and watering was done when needed. After the harvest, the chromium contents of the root and stem were determined. The chromium in the stem of the control was 2.81 mg/ kg, and it was 31.46 mg/kg in the stem of 80 mmol/kg EDTA application trial. This result was statistically significant at 5%. The chromium content of the root was 18.57 mmol/kg in the control condition while it was 34.95 mmol/kg in the root of the highest concentration of applied chelate. This study revealed that corn is a hyperaccumulator plant to be used in phytoremediation of the soils contaminated by Cr +6 .

“…The plant biomass decreased as a result of the Cu accumulation in plants (Kabata & Pendias 2001). A high Cu application has been reported to affect root length, damage root cells, and membranes, and cause imbalances in plant nutrient uptake (Lothe et al 2016). Copper toxicity is also known to disrupt physiological processes such as protein synthesis, photosynthesis, respiration, ion uptake, and cell membrane stability (Sossé et al 2004).…”

As industrial and agricultural activities intensify and technology rapidly advances, soil pollution has escalated to alarming levels. The increasing contamination of agricultural areas and the crops cultivated therein has emerged as a significant contemporary issue. Phytoremediation, the use of plants to remove pollutants, is a promising method for mitigating soil heavy metal contamination. This study investigates the bioaccumulation capacity of purslane (Portulaca oleracea L.), a potential phytoremediator, in soils artificially contaminated with cadmium (Cd), nickel (Ni), and copper (Cu). Purslane was cultivated under controlled conditions with varying doses of Cd, Ni, and Cu. After 55 days, the plants were harvested and analysed for heavy metal concentrations in their roots, stems, and leaves. Results demonstrated a direct correlation between environmental heavy metal concentration and plant heavy metal content, with the most significant accumulation occurring in the roots. Leaf chlorophyll content was adversely affected by increased Cd, Ni, and Cu applications. The highest Cu, Ni, and Cd contents were found in the roots at 140 mg kg-1 Cu, 80 mg kg-1 Ni, and 20 mg kg-1 Cd applications, respectively. The bio-transfer coefficient (BTC), a measure of heavy metal transport from the root region to the leaves, was calculated. The BTC values ranged from 0.84-1.09 for Cu, 0.39-0.84 for Ni, and >1 for Cd at the Control and 5 mg Cd kg-1 treatments. These findings suggest that purslane has potential for phytoremediation of heavy metal-contaminated soils, although the bioaccumulation and bio-transfer of heavy metals are dependent on the specific metal and its concentration in the soil. The study also highlights the potential risks associated with the consumption of plants grown in heavy metal-contaminated soils, as heavy metals can accumulate in different plant tissues, potentially entering the food chain.
