ClearProbabilistic environmental risk assessment of microplastics in soils
This study developed a probabilistic risk assessment framework for evaluating microplastic contamination in soils. Researchers analyzed data from multiple studies to estimate the likelihood and severity of microplastic risks to soil ecosystems. The findings indicate that agricultural soils are particularly vulnerable and that current contamination levels in some regions may already pose ecological risks.
Microplastics' Ecotoxicological Assessment and Quantification in the Soil Ecosystem

This review synthesizes research on microplastic contamination of soil environments, covering the major sources of soil microplastics, factors influencing their accumulation and distribution, and the environmental risks they pose to terrestrial ecosystems and agriculture.
Migration and toxicology of microplastics in soil: A review
This review examines how microplastics migrate through soil, summarizes their known toxic effects on soil organisms and plants, and identifies key gaps in current understanding. Soils are increasingly recognized as major microplastic repositories, and their contamination has implications for food safety and ecosystem health.
A review of microplastics in the soil environment
This review summarizes the current state of knowledge about microplastic contamination in soil environments, covering sources, distribution, and effects on soil organisms and ecosystems. The study highlights that while aquatic microplastic research is more advanced, soil contamination poses significant but understudied risks to terrestrial ecosystems and food production.
Soils in distress: The impacts and ecological risks of (micro)plastic pollution in the terrestrial environment
This review examines how microplastics affect soil ecosystems, including their transport into soils, changes they undergo in the environment, and their interactions with soil organisms. The effects depend heavily on the type, shape, size, and amount of plastic particles present. Understanding these impacts is important because soil contamination with microplastics can affect food production and ultimately human exposure through the food chain.
Soil-dwelling species-based biomarker as a sensitivity-risk measure of terrestrial ecosystems response to microplastics: A dose–response modeling approach
A dose-response modeling approach was applied to data from soil-dwelling organisms to assess the relative sensitivity of terrestrial ecosystems to microplastic contamination, producing species sensitivity distributions as a risk metric. The analysis revealed that certain soil invertebrates are particularly vulnerable even at relatively low microplastic concentrations.
Source, migration and toxicology of microplastics in soil
This review compiles research on the sources, movement, and toxic effects of microplastics in soil ecosystems, an area that has received less attention than aquatic pollution. Researchers describe how microplastics enter soil through agricultural practices, wastewater, and atmospheric deposition, then transfer through food chains to affect organisms at multiple levels. The study identifies major knowledge gaps and proposes management strategies to mitigate the ecological and human health risks of soil microplastic contamination.
A global review on the abundance and threats of microplastics in soils to terrestrial ecosystem and human health
This review examines microplastic pollution levels across agricultural, roadside, urban, and landfill soils worldwide, finding wide variation but consistent contamination. Microplastics alter soil pH, density, and water movement, disrupt microbial communities, inhibit plant growth, and affect soil animals. For humans, the concern is that microplastics in soil can enter the food chain through crops and contaminated water.
Microplastics as Emerging Soil Pollutants
This review covers how microplastics enter and accumulate in soils, their effects on soil health, microbial communities, soil fauna, and plant growth, and the implications of widespread soil plastic contamination for ecosystem function.
Microplastic diversity, risks and soil impacts: A multi-metric assessment across land-use systems
Researchers surveyed microplastic abundance, polymer diversity, and ecological risk across seven land-use types in India's Brahmaputra Valley, finding that built-up areas had the highest particle counts while forest soils paradoxically showed the greatest polymer hazard scores due to high-risk polymers, and that land-use type shapes both the quantity and composition of soil microplastic contamination.
Microplastics in terrestrial environments: Reviewing current understanding to determine the positive and negative aspects of soil
This review examines microplastics in terrestrial soils, covering their sources, distribution, and effects on soil health and organisms. It finds both negative impacts on soil function and organisms, as well as some neutral or context-dependent effects, and identifies key areas for future research.
Species sensitivity distributions of micro- and nanoplastics in soil based on particle characteristics
Researchers analyzed data from 74 studies to assess which soil organisms are most sensitive to micro and nanoplastics, finding that smaller particles and polystyrene types pose the greatest ecological risk. The hazardous concentration threshold for soil organisms was estimated at about 88 mg per kilogram of soil. This is the first study to factor in microplastic physical properties when calculating species sensitivity, providing a foundation for soil pollution guidelines.

The study calls for standardized methods and more research into how these tiny plastic particles move through and affect terrestrial ecosystems.
Source-specific probabilistic risk assessment of microplastics in soils applying quality criteria and data alignment methods
This study developed a risk assessment framework for microplastics in soil by comparing contamination from different sources including sewage sludge, agricultural mulch, and background pollution. Sewage-contaminated soils showed the highest proportion of samples exceeding risk thresholds, followed by background pollution from diffuse sources. The research provides tools for regulators to evaluate which soil contamination sources pose the greatest ecological risk, which matters for food safety since crops grown in these soils can take up microplastics.
