Extraction of Polyethylene and Polypropylene Microplastic from Agriculture Soil
Researchers examined methods for extracting polyethylene and polypropylene microplastics from agricultural soil, investigating how microplastic concentrations affect soil properties and crop productivity while evaluating density separation and other extraction protocols to improve detection and quantification of plastic pollution in agroecosystems.
Impact assessment of microplastics in agricultural soils of the Euroregion Galicia and Minho: preliminary results
Researchers assessed the impact of microplastic pollution on agricultural soils in the Euroregion Galicia-Norte Portugal, examining contamination levels across farmland as plastic use in agriculture intensifies globally. Microplastics were detected across sampled fields, with levels and types reflecting regional agricultural practices and plastic inputs.
A novel method for extraction of polypropylene microplastics in swine manure
This study developed a new extraction method for detecting and measuring polypropylene microplastics in swine manure, which is commonly applied to agricultural land as fertilizer. Livestock manure is an underappreciated pathway for microplastics to enter farm soils, and reliable extraction methods are needed to quantify this contamination route.
Development and application of tests for microplastic detection in soil
This thesis developed and evaluated methods for detecting and quantifying microplastics in soil samples, addressing the lack of standardized protocols for terrestrial environments. Accurate detection methods are essential for understanding how widespread microplastic contamination is in agricultural and natural soils.
An effective method for the rapid detection of microplastics in soil
A rapid and practical method was developed for detecting and identifying microplastics in soil, addressing the need for faster alternatives to existing time-consuming techniques. The method uses a combination of sieving and staining approaches to accelerate microplastic extraction and identification from soil samples.

First national reference of microplastic contamination of French soils
Researchers established the first nationwide reference data for microplastic contamination in French soils by analyzing 33 samples from diverse land uses across the country. They found microplastics in virtually all samples, with agricultural and urban soils showing the highest concentrations, and identified polyethylene and polypropylene as the most common polymer types. The study provides an important baseline for tracking future soil contamination trends in France.
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.
Management of agricultural plastic waste in Portugal to prevent microplastics
Researchers examined the management of agricultural plastic waste in Portugal, assessing how mismanagement of plastics used in farming has led to soil contamination with microplastics and identifying practices that reduce plastic fragmentation and environmental release. The study found gaps between best practices and actual farm-level waste management that result in preventable plastic accumulation in agricultural soils.
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. Soil is a particularly challenging material to work with because its organic matter and complex structure can interfere with accurate microplastic detection. The authors recommend combining multiple techniques and minimizing harsh chemical steps that could accidentally destroy the very plastic particles being measured.
Microplastic analysis in soils: A comparative assessment
Researchers compared six different analytical methods for detecting and measuring microplastics in soil, testing them across different soil types and plastic materials. Fluorescence microscopy achieved the highest recovery rates for larger particles, while mass-based techniques like pyrolysis gas chromatography were better suited for detecting very small microplastics. The study highlights that no single method works best for all situations, and combining techniques may be necessary for accurate microplastic assessment in soil.
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.
