ClearWater infiltration capacity in soil polluted with macroplastics
Researchers measured water infiltration rates in organic-rich coastal soils in central Norway that had accumulated buried macroplastic litter deposited by converging ocean currents, quantifying how macroplastic contamination alters vertical water transport capacity in these ecologically important near-coastal soils.
Macroplastic in soil and peat. A case study from the remote islands of Mausund and Froan landscape conservation area, Norway; implications for coastal cleanups and biodiversity
Researchers documented macroplastic accumulation in soil and peat on the remote Norwegian islands of Mausund and Froan, finding that marine plastic litter transported to these coastal conservation areas poses threats to terrestrial biodiversity and complicates cleanup efforts.
Interactions between water flow and microplastics in silt loam and loamy sand
Researchers found that increasing microplastic content (1-7% w/w) in both silt loam and loamy sand soils enhanced water infiltration rates, driving microplastic particles deeper into the soil profile. The study reveals a feedback mechanism where microplastics alter the very water flow patterns responsible for their own transport and distribution.
Saturated hydraulic conductivity in microplastics incorporated soils: Effects of soil texture, polymer type, particle size, and concentration
Researchers measured saturated hydraulic conductivity in loam and sandy loam soils amended with PET, PVC, and PE microplastics of two size classes, finding that PET particles in sandy loam produced the highest conductivity values and that polymer hydrophobicity and particle size both influence soil water flow.
Concentration‐ and Size‐Dependent Influences of Microplastics on Soil Hydraulic Properties and Water Flow
Researchers investigated how microplastic concentration and particle size affect soil hydraulic properties and water flow. They found that microplastic contamination reduced saturated conductivity by up to 50% and inhibited water infiltration, with higher concentrations and larger particle sizes leading to weaker soil water-holding capacity.
Indirect Effects of Microplastic-Contaminated Soils on Adjacent Soil Layers: Vertical Changes in Soil Physical Structure and Water Flow
Laboratory experiments showed that microplastic contamination in upper soil layers indirectly altered the physical structure and water flow of adjacent uncontaminated lower soil layers, suggesting that microplastics can affect soil hydrology beyond their immediate zone of contamination.
Horizontal transport of macro- and microplastics on soil surface by rainfall induced surface runoff as affected by vegetations
Researchers investigated how rainfall-induced surface runoff transports macro- and microplastics across soil surfaces, finding that vegetation cover significantly reduces plastic transport while plastic size, density, and rainfall intensity also influence horizontal movement.
Dispersion and transport of microplastics in three water-saturated coastal soils
Transport of three sizes of microplastics (0.3, 0.5, and 1 micrometer) through three water-saturated coastal soils was compared, finding that soil properties including organic matter content and ionic composition strongly influenced microplastic mobility and dispersion.
Experimental Investigation of Water-Retaining and Unsaturated Infiltration Characteristics of Loess Soils Imbued with Microplastics
Researchers conducted one-dimensional vertical soil column rainfall infiltration experiments on loess soil mixed with microplastics at varying content levels and particle sizes, finding that microplastics weakened soil water-retaining capacity and altered infiltration characteristics, with intermittent irrigation recommended to compensate for reduced soil permeability.
Effects of microplastics on the hydraulic properties and pore characteristics of compacted soil
Researchers investigated how polyethylene microplastics affect the hydraulic properties and pore structure of compacted soil, finding that higher microplastic concentrations disrupted pore size distribution and reduced saturated hydraulic conductivity while altering water retention capacity.
The soils of a high-traffic roadside ditch as a receptacle of macro-litter and microplastics
Researchers assessed macro-litter accumulation and microplastic infiltration in the soil of a roadside seepage ditch in the Parisian suburbs over eight months, measuring litter deposition rates of approximately 160 kg/km/year and collecting soil cores at up to 30 cm depth to quantify microplastic concentrations at different depths and evaluate vertical infiltration as a transport pathway.
Microplastic polymer type impacts water infiltration and its own transport in soil
Researchers conducted laboratory soil column experiments to examine how microplastic polymer type affects both water infiltration rates and the transport of the plastic particles themselves through soil, testing the two most commonly used agricultural microplastic types under controlled hydrological conditions. The study found that polymer type significantly influenced both water flow dynamics and microplastic mobility in soil, with important implications for predicting plastic fate in agricultural and natural terrestrial ecosystems.
Rainfall-induced microplastic fate and transport in unsaturated Dutch soils
This study simulated rainfall conditions to track how different types of microplastics move through Dutch soils, finding that sandy soils allowed significantly more microplastics to wash through than loamy soils. Heavier rainfall increased microplastic movement by up to 144% depending on the plastic type, with conventional polyethylene washing out most easily. The findings suggest that rain can carry microplastics from surface soil into groundwater, potentially contaminating drinking water sources.
Macro and microplastics in the soil: abundance, characterization, identification, and interactions under different land uses in an agricultural sub-basin
Researchers examined the abundance, characterization, identification, and interactions of macro- and microplastics in soils under different land uses within an agricultural sub-basin, assessing how land-use patterns influence plastic pollution distribution and potential interactions with the soil environment.
Vertical transport of microplastic in agricultural soil in controlled irrigation plot experiments
Researchers conducted field plot experiments in agricultural soil and found that microplastics migrate vertically with irrigation water, with smaller particles (53–63 µm) penetrating up to 6 cm deep and larger particles remaining near the surface, indicating that water infiltration is a key driver of subsurface plastic transport.

Microplastic contamination in soil environment – a review
This review examines the sources, transport, degradation, and ecological impacts of microplastic contamination in soil environments. The study suggests that soil acts as both a major sink for microplastics and a conduit transporting them to aquatic systems, and that microplastics can negatively affect soil organisms and biogeochemistry, underscoring the need for more research on terrestrial microplastic pollution.
Water retention and hydraulic properties of a natural soil subjected to microplastic contaminations and leachate exposures
Researchers studied how microplastic contamination affects the water-holding and flow properties of compacted soil, a scenario relevant to engineering applications like landfill liners. They found that microplastics altered the soil's ability to retain water and changed both saturated and unsaturated hydraulic conductivity, with effects varying by particle size and leachate age. The study suggests that microplastic-contaminated soils may behave differently than expected in engineered structures.
