ClearDisparities in Methods Used to Determine Microplastics in the Aquatic Environment: A Review of Legislation, Sampling Process and Instrumental Analysis
This review examined the wide disparities in sampling, processing, and analytical methods used across microplastic studies, highlighting how inconsistent approaches make it difficult to compare results and calling for standardized international protocols and regulatory frameworks.
Assessment of microplastic content in natural waters and sediments: sampling and sample preparation
Researchers reviewed and evaluated sampling and analytical methods for measuring microplastic content in natural waters and sediments, assessing sources of error and variability in current approaches. The review recommended a standardized protocol to improve cross-study comparability.
A breakthrough in the harmonization of microplastics monitoring protocols in latin american region
This paper describes progress toward harmonizing microplastic monitoring protocols across Latin American countries, aiming to create consistent, comparable data from a region with significant plastic pollution challenges but historically fragmented scientific approaches. Standardized monitoring is a prerequisite for effective regional policy and for understanding how plastic pollution flows through South and Central American river systems.

The assessment of microplastic and microfibres in freshwater systems through different sampling methods reveals causes of incomparability.
Researchers performed a literature mining study on microplastic abundance in freshwater systems, finding that large discrepancies between studies arise not only from inherent environmental variability but from methodological differences in sampling and analytical approaches, highlighting the urgent need for standardized protocols.
Revisión de métodos de muestreo, detección, caracterización de microplásticos y control de calidad en columna de agua y sedimentos
This Spanish-language review surveys the methods used to sample, detect, and characterize microplastics in water and sediments, cataloguing the advantages and limitations of each approach. The authors highlight that the lack of standardized protocols makes it impossible to reliably compare studies — a critical obstacle to understanding how widespread microplastic contamination really is and what it means for ecosystems and human health.
Microplastic analysis—are we measuring the same? Results on the first global comparative study for microplastic analysis in a water sample
Researchers conducted the first international comparative study of analytical methods for microplastic analysis in a water sample and found that comparability between methods was highly limited, underscoring the urgent need for standardized protocols in microplastic research.
A critical review of microplastics characterisation in aquatic environments: recent trends in the last 10 years

It identified persistent inconsistencies in methodology and recommended standardization practices to improve data comparability.
Methods for sampling, processing, identification,and quantification of microplastics in the marine environment
This paper reviews and compares the various methods used to collect, process, identify, and quantify microplastics across different environmental samples. It highlights the lack of standardized protocols as a major obstacle to comparing results across studies and calls for methodological harmonization.
A review of methods for measuring microplastics in aquatic environments
This review critically evaluates methods used to measure microplastics in aquatic environments, covering sampling design, sample processing, and spectroscopic identification, and identifies the most significant sources of methodological variation. Standardizing these methods is essential for generating comparable data across studies and enabling robust environmental risk assessment.
Improving monitoring, analysis and reporting to assess plastic pollution: a matter of comparability
This review examines two decades of microplastic monitoring in aquatic systems, identifying persistent challenges in harmonizing methodologies for sampling, analysis, and reporting that hinder data comparison, and proposing improvements to create comparable datasets for assessing plastic pollution from river basins to the ocean.
Techniques for Collecting Micro Plastics in Freshwaters and Sediments
This review examined sampling methods used across 150 studies on microplastics in freshwater bodies and sediments, finding significant variation in sampling tools, mesh sizes, and analytical approaches that make it difficult to compare results across studies. Standardizing sampling and analysis protocols is one of the most pressing needs in microplastic research. Without comparable methods, it is difficult to assess the true extent of freshwater microplastic contamination globally.
Microplastics: A Review of Methodology for Sampling and Characterizing Environmental and Biological Samples
This review examines the range of methodologies available for sampling and characterising environmental microplastics, highlighting how variability in collection, separation, detection, and identification procedures limits cross-study comparisons and discussing how complementary technique combinations can improve standardisation and data quality.
Microplastics in riverine systems: Recommendations for standardized sampling, separation, digestion and characterization
This paper provides standardized recommendations for microplastic sampling, separation, digestion, and characterization protocols in riverine systems, addressing methodological inconsistency that limits cross-study comparability. The authors propose harmonized operating procedures for field sampling and laboratory analysis to improve the reliability and comparability of microplastic data across river studies globally.
A Review of Analytical Methods Used in Microplastics Quantification
This review evaluates the various analytical methods used to detect and quantify microplastics in the environment, highlighting inconsistencies in sampling and analysis across studies. Standardizing methods is a critical priority for the field, as inconsistent approaches make it difficult to compare results and track pollution trends over time.
Comparision protocols for extraction of microplastics in water samples
Researchers compared four different extraction protocols for isolating microplastics from water samples and found significant differences in efficiency and accuracy across methods. Standardized extraction protocols are critical for producing comparable microplastic abundance data across studies. Without consistent methodology, it is difficult to build a reliable global picture of microplastic contamination levels in water.
Methods for Studying Microplastic Pollution in Natural Waters: Current State and Recommendations
This methodological review addresses the lack of standardization in how scientists sample, process, and report microplastic contamination in natural waters, which makes it nearly impossible to compare results across studies. It details quality assurance and quality control steps — especially important given how easily tiny plastic particles contaminate samples from the lab environment itself — and provides concrete recommendations for sampling protocols and data reporting. Harmonizing these methods is a critical step toward building a reliable global database of microplastic pollution.
Aquatic Microplastic Research—A Critique and Suggestions for the Future
This critical review argues that microplastic research lacks standardized collection and analysis methods, making it impossible to compare data across studies. The author calls for chemical identification of polymer types, whole-water sampling, and a focus on ecological impacts rather than just documenting presence.
Assessment of the Microplastics Content in Natural Waters and Sediments: Sampling and Sample Preparation
This review examines the challenges of sampling and preparing water and sediment samples for microplastic analysis, highlighting the lack of standardized methods. Researchers found that differences in collection techniques, sample volumes, and processing steps make it difficult to compare results across studies. The study calls for an internationally agreed-upon analytical framework to improve the reliability and consistency of microplastic monitoring worldwide.
Quantification of microplastics: Which parameters are essential for a reliable inter-study comparison?
Inconsistent measurement methods make it very difficult to compare microplastic data across studies. This paper proposes standardized guidelines for quantifying microplastic size and shape distributions, which would allow scientists to better track pollution levels over time and across locations.
