ClearImpact of microplastic pollution in terrestrial ecosystem on index and engineering properties of sandy soil: An experimental investigation
Researchers tested how different concentrations of three common plastic types affect the physical and engineering properties of sandy soil. They found that increasing microplastic contamination significantly altered soil characteristics including liquid limit, plasticity, compaction, and shear strength. The findings suggest that microplastic pollution in the ground could potentially compromise the structural stability of soil used in construction and land management.
Geotechnical Implications of Microplastics: A Review of Their Effects on Soil Mechanical Parameters
This review compiled and analyzed findings from previous studies on how microplastics affect soil mechanical parameters — including compressibility, permeability, shear strength, settlement, and slope stability — concluding that microplastic contamination can substantially alter geotechnical soil behavior with implications for engineering and construction.
Impact of microplastics on strength parameters of clayey, Sandy, silty soil: A comparative assessment
Researchers conducted a comparative study examining how three types of microplastics at different concentrations affect the strength properties of sandy, silty, and clayey soils over a 30-day period. They found that LDPE, HDPE, and PVC contamination at environmentally relevant levels altered key soil properties including moisture content, density, and shear strength. The study highlights that microplastic pollution could compromise soil structural integrity, with implications for construction and geotechnical engineering.

Microplastics in soils: an environmental geotechnics perspective
This geotechnical engineering perspective reviewed microplastic contamination in soils and the terrestrial subsurface, examining how MPs alter soil mechanical properties — including shear strength, hydraulic conductivity, and compressibility — and arguing that geotechnical impacts have been underappreciated in environmental assessments.
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.
Microplastic Contamination in Soils: A Review from Geotechnical Engineering View
Researchers reviewed microplastic contamination in soils from a geotechnical engineering perspective, examining how plastic degradation leads to widespread soil contamination. They identified landfills and various geotechnical applications such as tire chip fills and polystyrene lightweight fills as potential sources of microplastic pollution in soils. The review highlights the need for geotechnical engineers to consider the long-term effects of microplastic contamination on soil properties and groundwater quality.
Effect of low-density polyethylene, polyvinyl chloride, and high-density polyethylene micro-plastic contamination on the index and engineering properties of clayey soil- an experimental study
Researchers examined how low-density polyethylene, polyvinyl chloride, and high-density polyethylene microplastics affect the index and engineering properties of clayey soil, finding that microplastic contamination alters soil behavior relevant to geotechnical engineering.
Effects of microplastic contamination on the hydraulic, water retention, and desiccation crack properties of a natural clay exposed to leachate
Researchers examined how microplastic contamination affects the physical properties of natural clay soil exposed to landfill leachate. They found that microplastics significantly increased the soil's water permeability, reduced its water retention capacity, and altered desiccation cracking patterns. The findings suggest that microplastic pollution could compromise the integrity of clay barriers used in landfill liners and other engineering applications.
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.

Researchers investigated how microplastics of different sizes and types affect the physical properties of silt loam soil under repeated wetting and drying cycles.

Can Microplastic Pollution Change Soil-Water Dynamics? Results from Controlled Laboratory Experiments
Researchers conducted controlled laboratory experiments examining how microplastic shape and concentration affect soil water-holding capacity and evaporation in fine sand, finding through statistical and non-parametric analyses that microplastic pollution at environmentally relevant concentrations significantly altered both hydrological parameters.
Strain-Dependent Effects of Microplastic Contamination on the Strength and Modulus of Kaolin Clay
When wildfires burn plastic materials near cities, they create tiny plastic particles called microplastics that settle into soil with the ash. Scientists found that when these microplastics mix with clay soil, they change how strong and stiff the soil is, which could affect building foundations and construction safety. This matters because wildfires are becoming more common, potentially making contaminated soil a bigger problem for communities rebuilding after fires.
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.
Behaviour and transport of microplastics under saturated flow conditions in sediments and soils
Researchers investigated the behaviour and transport of microplastics under saturated flow conditions in sediments and soils, examining how particle properties influence movement through porous media. The study aimed to improve understanding of subsurface microplastic fate and transport relevant to both soil and groundwater contamination.
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.
Vertical migration of microplastics in porous media: Multiple controlling factors under wet-dry cycling
Researchers studied how microplastics move vertically through sandy soil during cycles of wetting and drying, testing four common plastic types at various particle sizes. They found that smaller, more hydrophobic particles migrated deeper, and that frequent wet-dry cycles and the presence of dissolved organic matter accelerated downward movement. The findings suggest that microplastics in agricultural soils could potentially reach groundwater, posing risks to underground water quality.
Overlooked yet critical pathways for microplastics input to soil and groundwater system: Transport mechanisms and simulation predictions in landfill environments
Researchers systematically investigated how microplastics travel through landfill soils into groundwater, examining the effects of particle density, size, polymer type, temperature, and salinity on transport.

Transport Mechanisms of Microplastics in Clean Sand under Cyclic Hydraulic Gradients
This laboratory study used column experiments to investigate how microplastics migrate through clean sand under cyclic hydraulic gradients — simulating conditions like flood-and-dry cycles or tidal fluctuations. The results showed that repeated changes in water flow direction caused microplastics to become trapped and remobilized in complex patterns, with pore-network changes playing a key role. Understanding how microplastics move through soils under climate-change-intensified weather extremes is crucial for predicting how these particles spread into groundwater and deeper sediment layers.
