“…Several scientific investigations have provided empirical evidence to substantiate the claim that an elevated concentration of Cadmium (Cd) has the potential to elicit detrimental consequences on the diverse array of organisms inhabiting soil ecosystems. Furthermore, it has been firmly established that this deleterious element can readily permeate the vegetative covering and subsequently infiltrate the intricate web of the food chain, thereby posing a significant threat to the overall ecological integrity and sustainability [49,50,51]. Hence, the Potential Ecological Risk Index reveals that Cd poses a considerable to very high ecological risk, emphasizing the need for environmental management and remediation efforts.…”

“…Moreover, concerning the direct geoenvironmental implications, the elevated concentrations of heavy metal pollution, particularly cadmium (Cd), present a direct hazard to the natural surroundings and conceivably to human well-being. The potential exposure to these pollutants via soil, water, or crops cultivated in the vicinity may result in detrimental health consequences, impacting both the ecological system and the inhabitants [56,55,51]. Furthermore, the presence of heavy metal contaminants in proximity can disturb the ecological balance in the immediate vicinity.…”

Soil, a vital biosphere component, is pivotal for human life, but its degradation adversely affects life quality. This study assessed soil pollution and index properties in Okpulor through geochemical, geotechnical, and geoenvironmental analyses. Twenty samples, comprising 14 surface and 6 shallow subsurface ones, underwent geochemical analysis for heavy metals (Fe, Cr, C, Cu, Zn, Ni, and Pb). Six geochemical models including Geoaccumulation Index (Igeo), Enrichment Factor (EF), Contamination Factor (CF), Metal Pollution Index (MPI), and Potential Ecological Risk Index (PERI) were employed. Simultaneously, six subsurface samples underwent geotechnical analysis for Natural Moisture Content, Grain Size, Specific Gravity, Bulk Density, and Atterberg Limits according to USCS and AASHTO guidelines. The Igeo highlighted significant Cd contamination, urging Cd source reduction for environmental mitigation. EF above 1.5 revealed substantial anthropogenic influence, emphasizing human activity control. CF accentuated Cd's contribution, requiring specific attention in environmental management. The PERI stressed Cd's ecological risks, necessitating targeted interventions. Natural moisture revealed initial soil conditions affecting contaminant mobility. High content enhanced leaching, emphasizing potential water-soluble contaminant migration. Bulk density and specific gravity assessed soil compaction and permeability, vital for understanding contaminant movement. Atterberg limits provided insights into plasticity and moisture retention, influencing contaminant behavior. Grain size analysis characterized particle distribution, impacting porosity, permeability, and contaminant movement. The interplay between geotechnical and geochemical properties unveiled contamination risks, urging holistic environmental management in Okpulor. Comprehensive consideration of the soils geotechnical index properties in environmental studies provides a holistic view of soil-contaminant interactions, emphasizing the need for strategic environmental management in Okpulor.

“…Phytoremediation is one of the bioremediation methods that involve an engineering incorporation of green plants for the remediation of toxic heavy metals from the soil (Balkrishna et al, 2022). Successful phytoremediation process involves a hyper-accumulator plant which uptakes high levels of heavy metal from the contaminated soil to the roots and translocate it to their shoots (Mahar et al, 2020). Plants of the genus Brassica have an inherent potential to accumulate heavy metals in their tissues (Diarra et al, 2021).…”

The current study investigated the use of nitrilotriacetic acid (NTA), a biodegradable chelating agent, on the phytoextraction of lead (Pb) from soil using Coronopus didymus. The plants were exposed to three different Pb concentrations: 3500, 4500, and 5500 mg kg-1 alone and in combination with 10 mM kg-1 of NTA. The morphological traits such as plant growth and biomass, the Bioconcentration Factor (BCF) values, and Pb accumulation in roots, stems, and leaves were measured. The plant growth and dry biomass were found to be maximum at 3500 mg kg-1 Pb and minimum at 5500 mg kg-1 Pb as compared to the control under Pb alone treatments and in combination with NTA. The supplementation of NTA significantly enhanced the Pb accumulation in different plant parts and was in the order: roots > stems > leaves. Compared to the BCF values of stems and leaves, the BCFroots values, which ranged from 89.3 to 257, were highest for all the treatments. NTA application resulted in the highest BCF value at 3500 mg kg−1 Pb concentration in roots. The present study suggests that the use of NTA as a chelating agent significantly increased the ability of C. didymus plants to remove Pb from the environment. This approach can be widely used for efficient remediation of contaminants from the metal-contaminated soils.
