Although the phytoremediation strategy has been studied worldwide, little research data are available regarding influence of mycorrhizae on capacity various plants grown in Cd-contaminated soils Mediterranean environments. Therefore, a pot experiment was carried out to study possible effectiveness hemp plant (Cannabis sativa L.) remediation moderately and heavily additionally quantify effect Cd Arbuscular Mycorrhizal Fungi (AMFs). For this purpose, an alkaline clay soil collected from Farm Institute Plant Breeding Genetic Resources (North Greece) contaminated with two levels (3 30 mg kg−1, corresponding Levels A B, respectively—first factor) at incubation times (10 days—second six treatments (Control_30d, Control_10d, CdA_30d, CdB_30d, CdA_10d, CdB_10d) were created. Soil concentrations, both pseudo-total plants, determined after extraction Aqua Regia mixture DTPA solution, respectively, before cultivation harvesting. concentrations aboveground underground parts also estimated digestion Regia, while root colonization by AMFs microscope. The highest plant’s concentration, more than 50%, observed its part, all treatments, indicating strong for cadmium gather up roots. Among different days, significant differences recorded rates AMFs. 3 Kg−1 promoted AMF colonization, particularly 10-day incubation, diminished it. Colonization lower longer Cd. Hemp appears be viable option phytostabilization soils, enabling further utilization assist process.

Validation of modified electrode surfaces as Sensitive Analytical Tools in Soil Analysis; Detection of Total Concentration of Zn (II), Cd(II), Pb(II), Cu(II)/Cu (I) along with Handling Complicated Sample Matrices

Published: April 30, 2024

Heavy metals constitute pollutants particularly common in air, water, and soil. They are present both urban rural environments, on land marine ecosystems, causing serious environmental problems since they do not degrade easily, remain almost unchanged for long periods, bioaccumulate. Detection, though especially quantification, is a systematic process as monitoring of their levels needs to be carried out at regular intervals there often seasonal variation. The need rapid low-cost determination therefore considerable. In the study atomic absorption spectroscopy (AAS), using flame or graphite furnace, square wave anodic stripping voltammetry (SWASV), bismuth thin film electrode, sensitive voltammetric method being compared analytically validated. Atomic (AAS) represents well-established analytical technique while criticized its applicability complicated sample matrices such soil samples. This sample-handling challenge investigated study. results show that methods AAS ASV were satisfactorily correlated showed concentration lower than limit values, but with increasing trend. Therefore, continuous metal complex city necessary matter great importance. Regarding Cd, detection limits Cd those when an overestimation was noted flame-AAS comparison found SWASV. SWASV has advantage cheaper faster, enabling simultaneous heavy elements across range concentrations these can occur Mediterranean soils. Additionally, we applied dsDNA-modified electrode which used speciation analysis Cu(I) Cu(II). changes characteristic peaks guanine adenine redox copper issue

Energy, Aromatic, and Medicinal Plants’ Potential and Prospects for the Remediation of Potentially Toxic Element-Contaminated Agricultural Soils: A Critical Meta-Analysis

Toxics, Journal Year: 2024, Volume and Issue: 12(12), P. 914 - 914

Published: Dec. 17, 2024

A critical meta-analysis of the past decade’s investigations was carried out with aim assessing use plant-based techniques for soil remediation. Potentially toxic element (PTE) contaminated soils were selected since these contaminants are considered hazardous and have long-term effects. Furthermore, energy, aromatic, medicinal plants studied as their high-value products seem to be affected by PTEs’ existence. Lead (Pb), Cu, Cd, Zn, Cr, Co, Ni, Hg, As accumulation in different parts plant species has been investigated using proper indices. Aromatic provide high phytoremediation yields. Increasing toxicity levels coexistence many metals enhance capacity aromatic plants, even Cd. In usable energy sources, antagonistic effects observed, simultaneous presence Cu Cd resulted lower thermic capacity. Finally, most studied, it observed that phytostabilization technique, i.e., mainly roots often used, allowing aboveground part almost completely free metallic pollutants. Using remediation proven advantageous within a circular economy model. Such process is promising solution, both economically environmentally, provides useful tool keeping environmental balance producing safe goods.
