ClearSample Collection, Preparation, and Identification of Microplastics in Soil: Issues and Recommendations
An evaluation of microplastic sampling and identification protocols from 39 global soil studies found major inconsistencies in sample collection strategies, preparation methods, and detection techniques, and proposed standardized recommendations to improve data comparability.
Quality assessment of research studies on microplastics in soils: A methodological perspective
A methodological quality assessment of published soil microplastic studies identified widespread inconsistencies in extraction, identification, and reporting protocols that limit comparability and reliability of findings. The review recommends adoption of standardized quality criteria to improve the rigor and reproducibility of soil microplastic research.
Investigating microplastic dynamics in soils: Orientation for sampling strategies and sample pre‐procession
This study develops improved methods for sampling and detecting microplastics in soil, addressing a major gap in current research. Standardized sampling strategies are essential because microplastic distribution in soil is highly variable, making it easy to miss contamination with inconsistent methods. Better detection protocols will help scientists accurately measure how much microplastic is accumulating in agricultural and natural soils.
A methodological approach of the current literature on microplastic contamination in terrestrial environments: Current knowledge and baseline considerations
This review of microplastic pollution in terrestrial and agricultural soils finds that a lack of standardized extraction and identification procedures makes most studies incomparable, calling for baseline contamination controls and harmonized reporting of concentrations, morphotypes, and analytical methods. The authors identify knowledge gaps for future research and provide minimum recommended procedures for field studies.
Global soil microplastic assessment in different land-use systems is largely determined by the method of analysis: A meta-analysis
This meta-analysis pooled data from 89 studies to measure microplastic levels in soils across different land uses worldwide. A key finding is that reported microplastic concentrations vary wildly depending on the testing method used, making it hard to compare studies. This highlights that before we can truly understand how much microplastic is in the soil that grows our food, scientists need to agree on standardized measurement methods.
Microplastic in Soil: a Review of Detection Methods
This review examines published approaches for detecting and identifying microplastics in soil environments, synthesizing sampling, extraction, and characterization methods to address the lack of standardization that hinders cross-study comparisons. Researchers found that unifying detection methods is essential for developing a common understanding of microplastic prevalence and impact in terrestrial ecosystems.
Soil microplastic analysis: a harmonized methodology
This review critically evaluates existing methods for sampling, separating, identifying, and quantifying microplastics in soils, and proposes a comprehensive eight-phase analytical methodology. Researchers emphasize that most current soil microplastic methods were adapted from marine research without adequately accounting for the complexity and heterogeneity of soil ecosystems. The study calls for globally coordinated standardization efforts to improve comparability of microplastic measurements across different soil studies.
Innovations in analytical methods to assess the occurrence of microplastics in soil
This review summarizes emerging techniques for extracting, analyzing, and characterizing microplastics in soil, noting that soil matrix complexity makes standardized methods challenging. Researchers found that globally, soil microplastic concentrations ranged up to 690,000 particles per kilogram, though most data comes from China. The study highlights the urgent need for standardized analytical methods to enable meaningful comparison of microplastic soil contamination across different studies and laboratories.
Microplastics in soil: A comprehensive review of occurrence, sources, fate, analytical techniques and potential impacts
This review analyzed microplastic contamination data from 62 sites across 17 countries and found that soil microplastic levels varied enormously depending on land use, with agricultural and urban soils most contaminated. The plastics affected soil organisms, plants, and microorganisms in complex ways, but inconsistent sampling methods across studies make it difficult to compare results and determine safe exposure thresholds.
Microplastics in soils: assessment, analytics and risks
This review examines microplastic prevalence, analytical methods, and risks in soils, finding that terrestrial microplastic contamination has received far less attention than marine accumulation despite comparable or greater abundance. Researchers evaluated current difficulties in soil microplastic sampling, isolation, and identification and called for standardised methodologies to assess ecological and human health risks.
Microplastics in sediments: A systematic review structured through reproducible analytical pipelines
This systematic review of 37 studies finds that microplastic research in sediments suffers from major differences in how samples are collected and analyzed. Without standardized methods, it is difficult to compare contamination levels across locations, which limits our ability to assess how much microplastic in soil and waterbed sediments might affect ecosystems and human health.
Sample Preparation Techniques for the Analysis of Microplastics in Soil—A Review
Sample preparation techniques for microplastic analysis in soil were reviewed and compared, noting that methods developed for aquatic systems are often inadequate for the complexity of soil matrices. The review highlights newly developed soil-specific methods and emphasizes the need for standardization to enable reliable comparison of terrestrial microplastic data.
A Cost-Effective Standardized Quantitative Detection Method for Soil Microplastics in Different Substrates
Scientists developed and validated a low-cost, standardized method for extracting and counting microplastics from different soil types—sandy, loam, and clay—achieving a 96.4% recovery rate at roughly $10 per sample in about 68 hours. The lack of consistent protocols has made it hard to compare microplastic data across studies globally, and this streamlined workflow directly addresses that problem. Better standardization will help researchers build a reliable picture of how contaminated agricultural soils really are worldwide.

Microplastics in soils: A comparative review on extraction, identification and quantification methods
This review compares the various methods scientists use to extract, identify, and measure microplastics in soil, highlighting the strengths and weaknesses of each approach.
