ClearMicroplastics in seawater: sampling strategies, laboratory methodologies, and identification techniques applied to port environment
A review of 74 global studies on microplastics in port environments was conducted as part of the EU Interreg SPlasH! project, synthesizing sampling strategies, laboratory methods, and results on abundance and distribution. The review highlights ports as significant hotspots for microplastic concentration and potential dispersal to the open sea.
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.
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.

This is a published correction notice for a previously published review article on microplastics in aquatic environments.
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.
Correction: Corrigendum: The presence of microplastics in commercial salts from different countries
This brief notice is a correction to a previously published paper reporting microplastic contamination in commercial salts. The corrigendum addresses technical errors in the original study findings without changing the overall conclusion that microplastics are detectable in sea salt intended for human consumption.
Progress on microplastics pollution and its ecological effects in the coastal environment
This review systematically summarizes a decade of research on microplastic pollution and its ecological effects in coastal environments worldwide, identifying persistent technical challenges in sampling standardization, particle identification, and ecological impact assessment. Researchers highlight the need for unified methodologies to better understand the sources, fate, and biological consequences of coastal microplastic contamination.
Microplastics in a Marine Environment: Review of Methods for Sampling, Processing, and Analyzing Microplastics in Water, Bottom Sediments, and Coastal Deposits
This review briefly describes the principal approaches, methods, and procedures for sampling and analysing microplastics in marine environments including water columns, bottom sediments, and coastal deposits. Researchers outline key considerations for each environmental matrix to support consistent and comparable microplastic monitoring.
A field and laboratory manual for sampling, processing and reporting microplastics in coastal and marine environments
This paper presents a comprehensive, standardized field and laboratory guideline for sampling, processing, and reporting microplastics in coastal and marine environments, developed through international collaboration. The harmonized protocols aim to improve comparability of data across global monitoring programmes.
Microplastics in coastal urban sediments: Discrepancies in concentration and character revealed by different approaches to sample processing
Researchers compared two microplastic extraction methods on intertidal sediment samples from three coastal sites near Plymouth, England, finding that direct counting under a stereo microscope yielded higher concentrations (0.58-0.79 MPs/g) than the ZnCl2 flotation-filtration method (0.18-0.48 MPs/g), highlighting methodological discrepancies that complicate cross-study comparisons.
Author Correction: Microplastic pollution in seawater and marine organisms across the Tropical Eastern Pacific and Galápagos
Researchers published a correction to their study on microplastic pollution across the Tropical Eastern Pacific and Galápagos, clarifying that plastic fibres were the dominant form found and specifying the location with the highest concentration of microplastic particles was in international waters. Microplastic fibres are among the most pervasive forms of plastic pollution in ocean environments worldwide.
Microplastics in seawater: a study of pretreatment, separation, and recovery.
Researchers developed and compared pretreatment, separation, and recovery methods for isolating microplastics from seawater samples, addressing the methodological diversity that limits comparability across marine monitoring studies. The study identified optimal combinations of techniques that improve microplastic recovery efficiency while minimizing contamination and sample loss.
Measures to prevent cross-contamination in the analysis of microplastics: A short literature review
A review of 115 marine microplastic studies from 2020 found that most researchers take some steps to prevent contamination of their samples, but few report how much contamination was actually avoided — with estimates ranging from under 1% to nearly 70% reduction. This methodological inconsistency means microplastic counts across studies may not be comparable, highlighting the urgent need for standardized sampling and lab protocols.
Adaptation of a laboratory protocol to quantity microplastics contamination in estuarine waters
Researchers adapted the NOAA microplastic extraction protocol for use in estuarine water samples, which present challenges due to high salt content and organic matter. Having a validated standard method for estuaries is important for monitoring microplastic pollution in these ecologically critical transitional environments.

On the harmonization of methods for measuring the occurrence, fate and effects of microplastics
This editorial introduces a themed journal issue on microplastics methods and calls for harmonization of sampling, extraction, and analysis procedures across the field. Inconsistent methods are one of the main barriers to comparing results between studies and drawing firm conclusions about microplastic pollution levels.

Microplastics are overestimated due to poor quality control of reagents
This study demonstrated that inadequate quality control of chemical reagents used in microplastic analysis can introduce contamination that leads to systematic overestimation of microplastic concentrations in environmental samples, highlighting a critical methodological flaw in the field.
