ClearSolid 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 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.
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.
Impact, Mitigation Strategies, and Future Possibilities of Nigerian Municipal Solid Waste Leachate Management Practices: A Review
This review assessed microplastic impacts, mitigation strategies, and future management possibilities for Nigeria, focusing on solid waste leachate from inadequately managed landfills as a major pollution pathway. The authors identified limited regulatory enforcement and lack of lined landfill infrastructure as key factors driving leachate contamination of groundwater and surface water.
Characterization of Microplastics and Associated Heavy Metals in Urban Soils Affected by Anthropogenic Littering: Distribution, Spatial Variation, and Influence of Soil Properties
Researchers sampled soils across residential, commercial, and industrial land-use types in urban areas and found microplastics in every location, with polypropylene, polyethylene, and polyamide as the dominant polymer types, at concentrations up to 850,000 particles per kilogram. Heavy metals were also associated with the plastic particles, meaning microplastics in urban soil may serve as combined carriers of chemical toxicants. The findings highlight urban soil as a major but underappreciated reservoir of microplastic pollution.
Hazards Associated with Plastic Wastes in the Communities of Niger Delta, Nigeria
A field study in Niger Delta communities measured plastic waste contamination in water, fish, sediment, and human blood samples, linking physicochemical anomalies to plastic pollution from local improper waste disposal.
A review of soil pollution around municipal solid waste landfills in Iran and comparable instances from other parts of the world
This review examines soil pollution around landfills in Iran and worldwide, covering heavy metals, toxic hydrocarbons, and microplastics as major contaminants. In developing countries like Iran, rapid urbanization and inadequate waste management are making the problem worse. The findings underscore that landfills are a significant source of microplastic contamination in surrounding soils and groundwater, posing ongoing risks to nearby communities.
Dataset on microplastics and associated trace metals and phthalate esters in sandy beaches of tropical Atlantic ecosystems, Nigeria
This dataset paper reports on microplastics found on four beaches in Nigeria's Gulf of Guinea, along with associated phthalate esters and heavy metals. The data confirm that microplastics in this region carry harmful chemical contaminants, raising concern for coastal communities and marine ecosystems.
Effect of landfill leachates on urban soil: A review
This review examines how landfill leachate — which contains heavy metals, organic compounds, and emerging contaminants — affects urban soils, in the context of global concerns about the 1.4 billion tonnes of municipal solid waste deposited in landfills annually.
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.
Assessment of Heavy Metal Exposure in Soils of Ihwrekreka Communities, Delta State, Nigeria
Soil samples from crude oil-polluted communities in the Ihwrekreka area of Nigeria's Niger Delta were analyzed for heavy metal concentrations using inductively coupled plasma optical emission spectrometry. The study assessed potential health risks to residents from exposure to chromium, nickel, lead, cadmium, and other metals elevated by decades of petroleum contamination.
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.
Identification of microplastics from urban informal solid waste landfill soil; MP associations with COD and chloride
Researchers identified microplastic concentrations of 180–1,120 particles per kilogram of soil in an urban informal landfill in India, with fragments and fibers as the dominant shapes, and found that microplastic presence altered key soil properties including conductivity and moisture content.
Microplastics in Urban Soils From Different Land Use Activities of Cyberjaya (Malaysia): Exploring Occurrence, Relationships, Sources and Pollution Level
Researchers surveyed urban soils across five different land uses in Cyberjaya, Malaysia, and found microplastics in all of them, with construction areas showing the highest concentrations. The types of plastic particles varied by location, suggesting that the sources and characteristics of soil microplastic contamination depend on what activities take place in that area.
Emerging Global Threat of Microplastics and Their Impact on Soil Sustainability: A Case of Southeast Nigeria
This review examined microplastic pollution in Southeast Nigeria, focusing on sources from fragmented plastic waste and environmental and health impacts. The authors highlighted local knowledge gaps and called for regional policies addressing the ecological and endocrine-disrupting effects of microplastics in a rapidly developing area.
Microplastic Abundance and Characteristics in The Soil Around the Jambi Talang Gulo Landfill
Researchers measured microplastic abundance and characterized particle types in soil surrounding the Talang Gulo landfill in Jambi, Indonesia, finding that the high volume of plastic waste at the facility contributes to elevated microplastic contamination in surrounding soils through environmental weathering and fragmentation.
Plastic Pollution in the Environment in Nigeria: A Rapid Systematic Review of the Sources, Distribution, Research Gaps and Policy Needs
This systematic review examines plastic pollution across Nigeria's environment, including water, soil, air, and food. The research finds that plastic contamination is widespread but under-studied in African countries, with significant gaps in data and policy. Understanding plastic pollution in developing nations is critical because these regions often lack the waste management infrastructure to prevent microplastic contamination of food and water.
