ClearGeotechnical 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.
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.
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.
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.
Impact 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.
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 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.
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.
Recent advances on ecological effects of microplastics on soil environment
This review summarizes recent advances in understanding the ecological effects of microplastics on soil environments. Researchers found that soils serve as major sinks for microplastics, which can alter soil properties, affect plant growth, disrupt soil microbial communities, and interact with other pollutants. The study highlights that terrestrial microplastic pollution may be even more pervasive than aquatic contamination and warrants greater research attention.
Impact of Microplastics on Soil Health: Soil-Water Retention, Shrinkage and Holding Properties
A review of research on microplastics in soil found that plastic particles can alter water retention, shrinkage, and structural properties in ways that could reduce agricultural productivity. Because microplastics are as prevalent in soils as in oceans, their terrestrial impacts warrant much greater research attention.
The Growing Problem of Soil Pollution with Microplastics: a Review
This review examined how microplastic accumulation in soil disrupts physicochemical properties including structure, porosity, and water retention, impairs soil microbial communities, inhibits plant growth, and causes oxidative stress, with agricultural soils identified as especially vulnerable to contamination.
Influence of Microplastic Contamination on Sand Liquefaction Initiation and Post-Liquefaction Behavior
Researchers assessed how microplastic contamination affects the dynamic properties of sand, specifically its susceptibility to liquefaction under cyclic loading.

Macro- and micro-plastics change soil physical properties: a systematic review
This systematic review examines how plastic particles — both large and microscopic — change important soil properties like water retention, density, and structure. These changes can affect how well soil supports plant growth and produces food, raising concerns about the long-term impact of plastic pollution on agriculture.
Geopolymer-based techniques for stabilization of microplastic contaminated expansive soil
This review investigates how microplastic contamination in clay-rich (expansive) soils alters their structural stability, and how geopolymer-based treatments can help. Microplastics disrupt the shrink-swell behavior of these soils, potentially destabilizing foundations and infrastructure built on them. The findings matter because agricultural and construction soils increasingly contain microplastics, and this work points toward chemical stabilization strategies that could reduce the resulting engineering hazards.
Effects of microplastics on soil physical, chemical and biological properties
This review examines how microplastics affect soil health, covering their impact on the physical structure, chemical composition, and biological communities of soil ecosystems. Microplastics can alter soil water retention, change nutrient cycling, and harm soil organisms from earthworms to microbes. Since agricultural soils are a major reservoir of microplastics, these changes could affect crop growth and food quality, creating an indirect pathway for microplastic-related harm to human health.
Impacts of Microplastics on the Soil Biophysical Environment
Four common microplastic types (polyacrylic fibers, polyamide beads, polyester fibers, PE fragments) were added to loamy sand soil at environmentally relevant concentrations in a garden experiment and effects on soil-water relationships, structure, and microbial function were measured over 5 weeks. Results showed that microplastics altered water repellency, aggregate stability, and microbial activity in a plastic-type-dependent manner, confirming that microplastics can disrupt fundamental soil biophysical processes.
