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.

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.

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.
