“…Heavy metals are extremely persistent in the environment; they are non-biodegradable and non-thermodegradable and thus readily accumulate to toxic levels. Long-term flow of waste waters from dumpsite on lands often results in the build-up of the elevated levels of heavy metals in soils (Tabari et al, 2008). Metal absorption and accumulation in a plant depends on many soil factors, such as-pH, EC, clay content, organic matter content and physical and mechanical characteristics of soil.…”

The study investigates the concentrations of heavy metals in Okra (Abelmoschus esculentus) planted in dumpsite soil obtained from the University of Benin and Ekosodin in Benin City. Soil samples were collected before and after planting and analyzed for pH, total nitrogen (N), total organic carbon (C), phosphorus (P), iron (Fe), zinc (Zn), manganese (Mn), and heavy metal concentrations (Cu, Pb, Cd, and Cr). The study reveals variations in soil acidity levels across different locations before and after planting. In Table 1, soil pH was moderately acidic in Farmland (5.61), neutral in Market (6.79) and Residential (6.76) areas, and slightly acidic in Faculties (6.14). In Table 2, after planting, the pH remained moderately acidic in Market (5.68) and Residential (5.80), while becoming strongly acidic in Farmland (5.42) and Faculties (5.36). Total N and P decreased in most dumpsites after planting, while total organic carbon increased. Fe, Zn, and Mn concentration varied between dumpsites and after planting stages. Particle size distribution remained predominantly sandy across dumpsites and planting stages. The study suggests that Okra plants cultivated in various dumpsite soils showed no toxic levels for the selected heavy metals, with concentrations generally falling within acceptable limits for vegetable consumption. The copper concentration highest uptake observed in Okra plants from Residential Land (36.0 mg/kg) and the lowest in Farmland (23.3 mg/kg). Lead (Pb) uptake varied across dumpsites: Market (0.15 mg/kg), Farmland (0.10 mg/kg), Residential Land (0.12 mg/kg), and Faculties (0.06 mg/kg). Cadmium (Cd) uptake was observed at Market dumpsites (0.05 mg/kg), Farmland (0.02 mg/kg), Residential Area (0.01 mg/kg), and Faculties (0.04 mg/kg). Heavy metal concentrations in the soil and Okra plants were generally below the permissible limits set by the Department of Petroleum Resources (DPR) for soil and World Health Organization (WHO) for vegetables intended for human consumption.

“…The use of wastewater and sludge in agricultural lands was found to enrich soils with heavy metals to concentrations that may pose potential environmental and health risks in the long-term (Tabari et al, 2008). Nwuche and Ugoji (2008) found heavy metal concentrations adversely affecting the biological health of the soil manifested in lower rates of nitrogen mineralization, lower soil microbial biomass carbon and reduced rate of respiration by soil microbial population.…”

This study analyzed the effect of different water sources of irrigation on the chemical constituents of soils in the Tamale Metropolis of Ghana. Soil samples were taken from depths of 0 – 30 cm and 30 – 60 cm in wastewater, pipe water and non-irrigated (control) sites. Variations in levels of concentration of the various chemical properties, however, occurred among the three different soils. With the exception of % N and Mg, there was no significant difference among all the three soils for all the parameters. The results indicated that N level increased in wastewater irrigated soils as compared to pipe water and non-irrigated soils. P increased with wastewater irrigation but decreased with soil depth. K concentration in wastewater irrigated soils increased in the depth of 0 – 30 cm but decreased in the depth of 30 – 60 cm. Wastewater and pipe water irrigation decreased soil Na and Cl levels compared to the control (non-irrigated soils). Wastewater irrigation increased the level of EC and CEC whilst Cu, Zn and Cd levels increased with soil depth. Cu, Zn and Cd levels of the wastewater, pipe water and non-irrigated soils were higher than the FAO (1985) recommended levels for both depths. It can be concluded that irrigation with wastewater increased soil primary macro nutrients (NPK) whilst micro nutrients such as sodium and chloride decreased with wastewater and pipe water irrigation.

“…The release of precious metals as solid or liquid waste unrecovered is accompanied by huge environmental impacts, but not economical, and poses financial and strong penalties burdens on industries (Ravindra et al 2004;Wei et al 2016). In addition, the mining and processing of precious and heavy metals have subjected human health and the ecosystem to unwarranted risks (Eisler 2004;Tabari et al 2008). Some critical health conditions, above the normal safety concentrations, have been attributed to the accumulation of metals in human bodies.…”

The loss of highly sought-after metals such as gold, silver, and platinum during extraction processes not only constitutes a significant waste of valuable resources but also contributes to alarming environmental pollution. The ever-growing adverse impacts of these highly valued metals significantly increase the contamination of water bodies on discharge, while reducing the reusability potential of their corresponding processed wastewater. It is, therefore, of great interest to identify pragmatic solutions for the recovery of precious materials from processed water. In this review, pollution from targeted precious metals such as gold, silver, platinum, palladium, iridium, ruthenium, and rhodium was reviewed and analyzed. Also, the hazardous effects are elicited, and detection techniques are enumerated. An insightful approach to more recent treatment techniques was also discussed. The study reveals nano- and bio-sorption techniques as adoptable pragmatic alternatives, among other techniques, especially for industrial applications with merits of cost, time, waste management, and eco-friendliness. The results indicate that gold (46.2%), palladium (23.1%), platinum (19.2%), and silver (11.5%) are of utmost interest when considering recent recovery techniques. High yield and cost analysis reduction are reasons for the observed preference of this recovery process when considering groups of precious metals. The challenges and prospects of nanomaterials are highlighted.
