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.

Urban Microplastic Pollution Revealed by a Large-Scale Wetland Soil Survey

Researchers conducted a large-scale survey of wetland soils across an urban area and found an average of 379 microplastic particles per kilogram, with abundance closely linked to proximity to the city's economic center. Polypropylene was the most common polymer type, and fiber and fragment shapes dominated the samples. The study found that atmospheric particle pollution and heavy metal concentrations in soil were strongly correlated with microplastic levels, suggesting shared urban pollution sources.

Global concentrations of microplastic in soils, a review

This global review synthesized data from studies on microplastic concentrations in soils worldwide, finding contamination across diverse terrestrial environments with higher levels near urban areas and agricultural land. Terrestrial soils are estimated to contain far more microplastic than the world's oceans, making them a critical but understudied reservoir of plastic pollution.

Microplastic Pollution in Residential Soils

Researchers collected surface soil from three residential density zones in Surabaya, Indonesia, and characterized microplastics by abundance, shape, color, and polymer type. Microplastics were present in all samples, with concentrations higher in denser residential areas, likely reflecting greater per-capita plastic use and outdoor plastic degradation.

Anthropogenic-vegetation dual controls on the hotspots of microplastic pollution in urban green space soil

Researchers investigated microplastic and phthalate ester contamination in urban green space soils across diverse land uses in Guangzhou, China, finding average MP abundances of 2,117 items/kg with significant spatial variability. Residential areas, street edges, and heavily trafficked zones were identified as hotspots, with both human activity and vegetation type driving contamination patterns.

Microplastics in soil: A comprehensive review of occurrence, sources, fate, analytical techniques and potential impacts

This review analyzed microplastic contamination data from 62 sites across 17 countries and found that soil microplastic levels varied enormously depending on land use, with agricultural and urban soils most contaminated. The plastics affected soil organisms, plants, and microorganisms in complex ways, but inconsistent sampling methods across studies make it difficult to compare results and determine safe exposure thresholds.

Children's playgrounds contain more microplastics than other areas in urban parks

Researchers measured microplastic contamination in sand, soil, and leaf samples from 19 children's playgrounds in Los Angeles urban parks. The study found that microplastic concentrations inside playgrounds were on average more than five times greater than in other park areas, with polyethylene and polypropylene being the most common polymers, suggesting that playground plastic structures may be a significant local source.

Distribution of microplastics in soil by types of land use in metropolitan area of Seoul

Researchers collected soil samples from five types of land in Seoul — farms, roadsides, residential areas, parks, and forests — and found microplastics in all of them, with agricultural land and roadsides showing the highest concentrations. Common plastic types included polyethylene and polypropylene, highlighting how everyday land use spreads microplastic contamination even far from obvious pollution sources.

Low-Density Microplastics in Recreational Parks of Al Ain, United Arab Emirates: Abundance, Composition, and Potential Effects on Soil Health

Researchers collected soil samples from recreational parks in Al Ain, United Arab Emirates and found varying levels of low-density microplastics caused by activities such as sludge application and use of reclaimed wastewater. The most common types were fibers and fragments made of polyethylene and polypropylene. The study suggests that urban recreational parks serve as accumulation sites for microplastic debris, raising concerns about soil health and the potential for human exposure in public spaces.

A global review on the abundance and threats of microplastics in soils to terrestrial ecosystem and human health

This review examines microplastic pollution levels across agricultural, roadside, urban, and landfill soils worldwide, finding wide variation but consistent contamination. Microplastics alter soil pH, density, and water movement, disrupt microbial communities, inhibit plant growth, and affect soil animals. For humans, the concern is that microplastics in soil can enter the food chain through crops and contaminated water.

Microplastic pollution in terrestrial environment: Identification, characterization, and risk assessment in Indore, Central India

Researchers measured microplastic contamination in soil from agricultural and recreational areas in Indore, India. Recreational sites had about six times more microplastic particles than farmland, with most particles made of common plastics like PET and polypropylene. While the ecological risk was rated low for now, the long-term buildup of these particles in soil could eventually pose threats to crops and the food chain.
