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.

“…Contamination of soil with PTEs is a worldwide environmental concern and continues to increase due to massive increases in industrialization, urbanization, human population, and consumption patterns [9,10]. Soil deterioration by PTE can cause lasting problems in the biogeochemical cycle and may in uence soil natural function, leading to changes in soil fauna [11], agricultural soils, and food crops [12].…”

“…Exposure to PTEs is associated with health implications to the human system, such as liver failure, nervous disorders, kidney disease, and neurotoxicity, either by ingestion or inhalation [16,17]. Furthermore, there is a need for effective monitoring of PTE sources, and distribution to reduce environmental damages, checkmate pollution, and public health as a result of anthropogenic activities [12].…”

Cement plants are the major anthropogenic sources of potentially toxic elements (PTEs), which are generated from the processing of raw materials and combustion of fossil fuels. This study determined the PTE concentration and assessed the geochemical, ecological, and health risks associated with the activities in the Ashaka cement plant, Bajoga, Nigeria. Soil samples were collected between 2019 and 2020, and analyzed by ICP-OES for 20 PTEs. The data obtained were statistically evaluated for descriptive and inferential statistics. The mean concentrations of PTEs were in the declined order of Al > Fe > Mn > Zn > Ti > Ba > Sr > Pb > Cu > V > Cr > Ni > As > Sc > Mo > Hg > Cd > Se > Sb > Co. Multivariate analysis revealed that the main sources of PTEs might be related to anthropogenic activities from cement plant. The geochemical load index (GLI) values obtained range from unpolluted to moderate. The ecological risk ranged from 4.74 × 10− 3 to 8.00 × 100, and the overall risk index indicated low contamination for the investigated elements. The hazard index (HI) was < 1, suggesting non-probable non-carcinogenic effects. However, children were more susceptible to risk than adults, and the cancer risk (CR) values of Cd for children and adults were higher than the threshold level of 1.0 × 10− 4, which suggests probable development of cancer risk for residents.

“…The health hazards associated with HMs, owing to their elevated biotoxicity and enduring presence in the environment, has been conducted via multiple exposure routes, encompassing ingestion, inhalation, and dermal contact (Oluwasola et al, 2021). Numerous indices, including the pollution load index (PLI), contamination factor (CF), ecological risk factor (ERF), and geo-accumulation index (Igeo), have been developed to evaluate soil pollution caused by heavy metals (HMs) (Proshad et al, 2022).…”

Faulty irrigation practices and industrial activities lead to the pollution of heavy metals (HMs) in agricultural soil, resulting in adverse effects on human health. The present study was conducted for the assessment of source identification, probabilistic health hazard assessments, and analysis of dietary risks associated with HM pollution in the calcareous soil of India. The mean concentrations of total and bioavailable forms of heavy metals (Cr, Ni, Cd, Pb, Cu) surpassed the permissible limits in sample areas (zone1 and 2), with zone 1 showing higher contamination levels compared to zone 2. The free ion activity model (FIAM) was employed to detect HMs in contaminated soil and assess their potential transfer to rice grains. Hazard quotient values were notably higher than the safe threshold (FIAM-HQ < 0.5) for Cr (2.87E-01), Ni (1.08E-01), and Pb (1.88E-01), except for Cd (1.49E-02) and Cu (1.27E-03), which remained within safe limits. Risk thermometer indicates high and moderate human health risk for Cr (CrSAMOE= 0.006) and Ni (NiSAMOE= 0.03), respectively. Self-organizing map (SOM) and positive matrix factorization (PMF) identify pollution sources in the calcareous region. Monte Carlo simulation (MCS) unveiled that children were more vulnerable to total carcinogenic risk (TCR) compared to adults through the ingestion pathway. A geostatistical approach was employed to predict the spatial distribution patterns of various heavy metals across the area. This comprehensive evaluation, utilizing appropriate and reasonable methods, serves as a valuable resource for environmental scientists and policymakers aiming to manage and mitigate HM pollution in agricultural soils near residential areas.
