This study measured zinc concentrations in the root, stem, and leaf tissues of maize grown on open dumpsite soils in Anyigba, Nigeria, finding elevated Zn levels in plant tissues compared to reference soils. The results documented the uptake of heavy metals—released by plastic-containing wastes—into edible crops grown near unmanaged dump sites.
Solid Waste Disposal and Extent of Selected Heavy Metals in Fadama Area of Sokoto City, Nigeria
This study assessed solid waste disposal practices and heavy metal concentrations in the Fadama area of Sokoto city, Nigeria, finding elevated levels of multiple metals in soil samples attributable to improper waste dumping, with implications for public health in communities living near informal disposal sites.
Environmental Impact of Bush Burning on the Physico-Chemistry of Mangrove Soil at Eagle Island, Niger Delta, Nigeria
Researchers examined the effect of bush burning on soil chemistry in mangrove wetland soils at Eagle Island in the Niger Delta, comparing nutrient element concentrations in burnt and unburnt soils at varying distances from the burn site. Results showed no significant difference between burned and unburned soil metal concentrations (P = 0.07), with iron being the dominant element in both, suggesting burning may increase soil metal content through ash deposition rather than degrading it.
Investigation of microplastic contamination in waste dump soil from Minna Metropolis in Niger State and screening of indigenous microorganisms for biodegradation as potential mitigation strategy
Researchers investigated microplastic contamination in waste dump soils across Minna, Nigeria, and screened indigenous soil microorganisms for plastic biodegradation potential. They found microplastics in all sampled dump sites and identified several bacterial isolates capable of degrading common plastic polymers.
Proximate, Phytochemical and Antibacterial Properties of Ethanol Extracts of Zeamays and Teiferia occidentalis Plant Leaves from Plastic Enriched Compost Soil in Edo State, Nigeria
This Nigerian study examined the nutritional and antimicrobial properties of plants grown in plastic-enriched compost soil, finding differences compared to control plants. The results suggest that growing crops in plastic-contaminated soil can affect plant chemistry, with potential implications for food quality and safety.
Environmental and Toxicological Perspectives of Soil Microplastics in Northern Nigeria
This study examined microplastic occurrence and toxicological implications in soils of Northern Nigeria, identifying agricultural plastics, industrial waste, and urban runoff as key sources. The research addressed a gap in African soil MP research and highlighted ecosystem and food safety risks in the region.
Assessment of Heavy Metals and Phytochemicals in Soil and Rice Samples Cultivated in a Selected Agricultural Region of Nigeria.
This study assessed concentrations of heavy metals (Pb, Cd, Zn, Fe, Cu, Cr, Ni) and phytochemicals in soil and rice samples from agricultural regions in Abuja and Kogi State, Nigeria, evaluating bioaccumulation risks and food safety implications for populations consuming locally grown rice.
Microplastic Contamination and Its Impact on Soil Properties Across Different Land Uses in Cross River State, Nigeria
A survey of soils across four land-use types in southeastern Nigeria found microplastic concentrations up to 12 times higher in commercial areas than in forests, with contamination linked to changes in soil structure, nutrient availability, and water infiltration. This is the first large-scale assessment of microplastic distribution in Nigerian tropical soils, filling a major data gap for sub-Saharan Africa. The findings suggest that heavily contaminated commercial soils may have degraded agricultural and ecological functionality, with consequences for food security in the region.
Spatial distribution and ecological risks of microplastics in agricultural soils near a solid waste dumpsite in southwest Bangladesh
Researchers assessed microplastic contamination in agricultural soils surrounding a municipal solid waste dumpsite in southwest Bangladesh, characterizing the types, spatial distribution, and ecological risks. They found significant microplastic accumulation in soils near the dump, with contamination levels decreasing at greater distances. The study highlights that waste dumpsites are important point sources of microplastic pollution that can affect the fertility and ecological health of surrounding agricultural lands.
Bioaccumulation of Heavy Metals in a Soil–Plant System from an Open Dumpsite and the Associated Health Risks through Multiple Routes
Researchers studied heavy metal contamination in soil and plants at a municipal waste dump site, screening native plant species for their ability to absorb and accumulate metals. They found that certain plants showed strong potential as hyperaccumulators that could be used for bioremediation of contaminated land. The study also assessed health risks to nearby populations from exposure through ingestion, skin contact, and inhalation of contaminated soil and plant material.
An Assessment of the Suitability of Contrasting Biosolids for Raising Indigenous Plants in Nurseries
Researchers assessed three biosolids and one pond sludge as amendments for growing six indigenous plant species in nurseries for ecosystem restoration, finding significant positive correlations between plant growth and biosolid addition up to species-dependent optima (10% fresh, 30% aged), with increased foliar N, P, K, S, and Zn but no phytotoxic trace element accumulation.
Polycyclic Aromatic Hydrocarbons in Soil and Vegetation of Niger Delta, Nigeria: Ecological Risk Assessment
Researchers assessed polycyclic aromatic hydrocarbon contamination in soils and vegetation across Nigeria's Niger Delta, finding elevated PAH levels in both matrices near oil exploration sites with ecological risk indices indicating significant environmental concern.
Occurrence of emerging and persistent organic pollutants in dumpsite environments: A review
Researchers reviewed 86 studies on pollutants found at waste dumpsites — including microplastics, industrial chemicals, and pharmaceuticals — and found that crops grown near these sites are dangerously understudied despite being a food source for millions of low-income people. Microplastics were the most commonly reported pollutant, but a lack of standardized measurement methods makes it difficult to compare findings across regions.

Researchers assessed microplastic contamination in organic soil amendments, including municipal compost and sewage sludge, used in the Greater Accra region of Ghana. They found microplastic concentrations ranging from about 2,000 to over 4,300 particles per kilogram, far exceeding levels in native soil. The study reveals that organic fertilizers, often considered eco-friendly alternatives, can be a significant source of microplastic pollution in agricultural soils.
Effects of microplastics and biochar on soil cadmium availability and wheat plant performance
Researchers found that fresh microplastics increased soil cadmium availability and plant uptake in wheat, and when combined with biochar, microplastics further amplified cadmium mobilization by decreasing soil pH and increasing dissolved organic matter, complicating biochar-based soil remediation strategies.
Characterization of tidally accumulated plastic waste and its effect on seedling growth in sand-filled mangrove forest at Eagle Island, Niger Delta, Nigeria
Researchers characterized tidally accumulated plastic waste and its effects on mangrove seedling growth at a sand-filled deforested mangrove site at Eagle Island in the Niger Delta, Nigeria, analyzing heavy metals and total hydrocarbons in soils beneath plastic waste alongside seedling growth comparisons. They found that while heavy metal concentrations did not differ significantly by soil depth, seedling growth was significantly impaired in plastic-contaminated soils, and horizontal migration of plastic-associated pollutants was detected in surrounding soils.
