“…With a control sample in the first week (Figure 4B), according to Figure 4 (b) and 5 (b), there was a significant difference between the amount of Cu and Zn in the CAR fraction in different biochar treatments. Also, the CAR fraction of Zn decreased from 22% in control to 12.37% in 10% biochar treatment in the eighth week, which is consistent with the research of Hamzenejad Taghlidabad and Sepehr [11]. In this study, the reduction of Cu and Zn concentrations in CAR and EX fractions in different biochar treatments indicates that these treatments could convert Zn and Cu into more stable forms.…”

“…They reported that the use of biochar has positive effects on stabilizing heavy metals by reducing their mobility in soil [10]. Furthermore, Hamzenejad Taghlidabad and Sepehr reported that the application of biochar of grape pruning residues significantly reduces the elements in the exchangeable and carbonate fraction and significantly increases the elements in Organic Matter bound (OM) and Oxides bound (OX) fraction in the soil [11]. Gholami and Rahimi, in a study, using sequential extraction method, and Tessier et al [12,13] stated that the use of different levels of carrot pulp in contaminated soil reduces the Exchangeable (EX) and Carbonate (CAR) fraction of Cu and Zn but OX, OM and Residual (RES) fraction increase.…”

Background: Drill Cutting (DC) are large amount of waste generated in gas and oil exploration and production activities that contains toxic substances, especially heavy metals. This study aimed to use Conocarpus Waste (CW) biochar to investigate its effects on changes in chemical forms and stabilization and distribution of Cu and Zn in DC samples of Ahvaz oil field at different incubation times. Methods: In order to study the effects of CW biochar at different rates (0, 2, 5, and 10% w/w) and four incubation times (1, 2, 4, and 8 weeks) for adsorption and chemical fractionation of Copper (Cu) and Zinc (Zn) in DC of Ahvaz oil field in southwestern Iran. An experiment was conducted as a factorial in a completely randomized designing in three replication. Sequential extraction procedure of Tessier was applied for the determination of heavy metals fraction. Results: Application of biochar significantly (p <0.05) increased the pH, soil organic carbon (SOC), electrical conductivity (EC), and cation exchange capacity (CEC) especially at the 10% application rate. After the addition of CW biochar, the exchangeable (EX) and carbonate (CAR) fractions of Cu and Zn, respectively decreased (P≤0.05) significantly while organic matter (OM) bound, oxides (OX) bound, and residual (RES) fraction were increased. Conclusion: The CW biochar can be a low-cost and effective amendment in immobilizing the Cu and Zn, and also effectively to reducing their mobility in DC.

“…Wang et al (2017) and Elloumi et al (2016) mentioned that heavy metal ions in soil-plant systems can enter the plant by the roots and accumulate, considering this as another source of contamination. In other studies, Komárek et al (2013) and Hamzenejad- Taghlidabad & Sepehr (2018) commented that high soil pH can also facilitate both, the absorption of metal cations in soils and the precipitation of heavy metals, which influences the uptake of heavy metals by plants. However, from the nutrimental point of view, Khan et al (2019) commented that the consumption of habanero pepper can serve as a supplement for supplying major elements (Ca, Mg, K and Na) required in the daily diet since vegetables represent the main source of Ca; although, its concentration varies from one vegetable to another.…”

The aim of this work was to determine in Capsicum chinense the 1) concentration of heavy metals (Al, As, Cd, Pb), majority (Ca, K, Mg, Na) and essential (Cu, Fe, Mn, Se, Zn) mineral elements, 2) effects of ripening stage, harvest number and type of soil on the mineral content and 3) authenticity markers. Peppers grown in black and red soils of this Mayan region, were harvested in two ripening stages (ripe and ripening peppers [orange and green peppers, respectivily]) and in four post-transplant dates: I (132 post-transplant days, PTD), II (160PTD), III (209PTD) and IV (265PTD). These samples were analyzed by ICP-Spectroscopy. The ripening stage affected the Al, Cu and Zn contents in ripe peppers while As presented the highest content in ripening peppers. Harvests I y III presented the highest Al, Ca, K contents while harvests II y III presented the highest As and Pb contents. Nine and ten elements developed authenticity markers according to the maturation and harvest number, respectively. The results obtained will help the producers and industrialists to focused on the production and agronomic management of high quality habanero peppers.

“…Nanoparticles of copper oxide with a diameter of 40-60 nm and a concentration of 0.005 g/mL were simultaneously applied to the polymerization owing to its ability to remove metals (Hamzenejad et al 2018). To initiate the polymerization process, the base membrane was immersed in the Pyrrole solution for at least 40 hours.…”

Electrokinetic remediation is a process in which a direct electric current is applied across a section of contaminated soil to remove metals. To improve the electrokinetic remediation in this study, a conductive membrane was fabricated via in-situ chemical polymerization employing Pyrrole and copper oxide nanoparticles. The fabricated membrane was placed in an electric field as part of the electrode structure. A physical model was constructed and filled with copper contaminated kaolinite in the concentration of 200 mg/kg. To control the pH, 0.1 M citric acid and 0.01 M potassium chloride were used as the electrolyte solutions. The results showed that the minimum surface resistivity of the fabricated membrane under a maximum pressure of 8.2 (kPa) was 2.55 kΩ /m 2 . The experimental results demonstrated that the use of citric acid as an electrolyte was more useful to desorb the copper due to the formation of the copper-citrate complex. Also, the results showed that employing the fabricated membrane (as part of the electrode structure) accelerated the removal of the copper by the use of the enhancing agents. The average percentage decrease of copper (with the use of fabricated membrane relative to the control test) was 51% and 21% in GM-2/CT-2 and GM-1/CT-1, respectively.The highest power consumption was obtained in experiments using citric acid. Due to the higher removal efficiency of copper in GM-2, the energy utilization efficiency () increased and reached 29.9 near  value of GM-1 with the lowest power consumption.
