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.
Subsurface transport and environmental risks of microplastic pollution: influence of land use and seasonal variability
Researchers systematically investigated how microplastics move vertically through soil across five different land use types during pre-monsoon and post-monsoon seasons. Dumpsites had the highest microplastic concentrations at nearly 40,000 particles per kilogram, while woodlands had the lowest at around 500 particles per kilogram. The study found that smaller microplastics traveled deeper into soil, especially after monsoon rains, and that land use type significantly influenced both the amount and composition of microplastic contamination.
Examining Soil Microplastics: Prevalence and Consequences Across Varied Land Use Contexts
Scientists examined microplastic contamination in soil samples from different land use areas in Makassar City, Indonesia. They found microplastics present across all sites, with the types and concentrations varying based on how the land was used, whether for agriculture, residential, or commercial purposes. The study suggests that human activity patterns strongly influence the amount and kind of microplastic pollution found in urban and agricultural soils.
Impact of land-use patterns on soil microplastics: Distribution characteristics and driving factors in southern China’s Pearl River Delta
