Levels of Heavy Metals in the Soil of Illegal Open Dumpsites in Malaysia
Researchers collected and analyzed soil samples from two illegal dumpsites in Malaysia -- one receiving construction waste and one receiving municipal solid waste -- measuring heavy metal levels in triplicate over two sampling periods. They found elevated concentrations of multiple heavy metals at both sites, with temporal variation between sampling weeks, indicating ongoing leaching and accumulation risks for surrounding soil environments.

Pollution and health risk assessment of heavy metals in the soil around an open landfill site in a developing country
Researchers evaluated soil pollution and ecological and human health risks from heavy metals around a municipal solid waste landfill in Kazerun, Iran, collecting soil samples at multiple distances and depths from the site. They found elevated concentrations of multiple heavy metals in landfill-proximal soils compared to background levels, with risk indices indicating potential carcinogenic and non-carcinogenic hazards particularly for children through soil ingestion pathways.
Are anthropogenic soils from dumpsites suitable for arable fields? Evaluation of soil fertility and transfer of potentially toxic elements to plants
Researchers evaluated the fertility of anthropogenic soils from an abandoned dumpsite in Nigeria, examining whether these soils are suitable for agriculture by measuring nutrient levels and the bioaccessibility of potentially toxic elements to plants.
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.
Assessment of occupational risks of waste scavenging in Ilorin metropolis
Researchers assessed the occupational health risks facing waste scavengers working at dumpsites in Ilorin, Nigeria. The study found that scavenging was predominantly performed by young males with very low use of personal protective equipment and no prior safety training, and the most prevalent health issues included fever, diarrhea, cough, and skin diseases.
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.
The Study of Peri-Urban Soil Contamination in the Kenitra Region, Morocco – Characterization and Assessment Using a Statistical Approach
Researchers characterized peri-urban soil contamination in the Kenitra region of Morocco, analyzing inorganic and organic pollutant concentrations in solid waste-impacted soils and assessing associated environmental risks. The study documented significant pollution levels and highlighted the growing threat of unmanaged solid waste to peri-urban soil quality.
The Health-trash Nexus in Challenging Environments: A Spatial Mixed Methods Analysis of Accra, Ghana
This mixed-methods study in Accra, Ghana analyzed the spatial relationship between waste disposal practices and health outcomes in a rapidly urbanizing city. Open dumping and poor waste management create conditions where microplastics and other contaminants accumulate near communities, with direct public health consequences.
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.
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.
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.
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.
