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 Can Change Soil Properties and Affect Plant Performance

Researchers tested six different types of microplastics in soil and found that they altered key soil properties including water-holding capacity, bulk density, and microbial activity. These changes in soil structure had cascading effects on plant growth, with some microplastic types reducing above-ground biomass. The study demonstrates that microplastics can fundamentally change how soil functions, with consequences for plant health and ecosystem stability.

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.

Determinants of environmental changes in human-modified ecosystems: Effects of plastics on moisture gradients, nutrients, and clay properties

Researchers examined how plastic pollution affects soil properties in human-modified ecosystems through field experiments in China and Rwanda, combined with laboratory tests on clay mixed with PET microplastics. They found that microplastics altered the structural properties of natural clay, decreasing moisture content while increasing density and load-bearing capacity. The study suggests that plastic accumulation in soils can fundamentally change moisture gradients, nutrient availability, and physical soil characteristics.

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.

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.

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.
