ClearProtocol for Riverine Macroplastic Monitoring: Long-term and Cost-effective Monitoring of Riverine Plastic Debris Pollution in the Lower Mekong River
This protocol document establishes standardized methods for monitoring macroplastic debris in the Mekong River — identified as one of the world's top plastic-contributing rivers to the ocean. Reliable long-term monitoring data is foundational for understanding riverine plastic transport and designing effective reduction interventions.
Protocol for Microplastic Monitoring in Fish
Researchers developed a standardized protocol for monitoring microplastics in fish in the Mekong River Basin, responding to evidence that the Mekong is among the ten rivers contributing over 90% of plastic debris to the global marine environment.
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.
Riverine Plastic Pollution: Field Sampling Protocol and Implementation in U.S. Rivers
This paper presents a standardized field sampling protocol for measuring plastic pollution in U.S. rivers. Consistent methodology is essential for comparing data across studies and is designed to capture both surface and submerged plastics including microplastics in riverine systems.
Microplastics pollution in selected rivers from Southeast Asia
Researchers surveyed microplastic pollution in rivers across Southeast Asia, a region with high plastic waste discharge but limited monitoring data, documenting the distribution and characteristics of microplastics in these understudied waterways.
A multidimensional approach for microplastics monitoring in two major tropical river basins, Malaysia
Researchers conducted a multidimensional assessment of microplastic distribution in surface waters of two major Malaysian river basins, providing much-needed field data on microplastic emissions from Asian rivers known to be major contributors to ocean pollution.
A Practical Overview of Methodologies for Sampling and Analysis of Microplastics in Riverine Environments
This practical review compiles and evaluates sampling and analytical methods for detecting and characterizing microplastics in rivers, including collection devices, extraction protocols, and spectroscopic identification techniques. It provides guidance for researchers designing monitoring studies to ensure reliable and comparable results.
Microplastics in the riverine environment: Meta-analysis and quality criteria for developing robust field sampling procedures
This meta-analysis reviews how microplastics are sampled in rivers and finds that current methods are inconsistent, making it hard to compare results across studies. Better standardized sampling approaches are needed to accurately measure how much microplastic pollution flows through rivers that supply drinking water to communities.
A Methodology to Characterize Riverine Macroplastic Emission Into the Ocean
This paper presents a standardized methodology for measuring and characterizing macroplastic emissions from rivers into the ocean, addressing a major data gap in global plastic budget estimates. Consistent measurement frameworks are essential for understanding how much plastic enters the ocean from land-based sources via rivers.
Development of cost-effective methodologies to identify and quantify microplastics in seawater samples
Researchers developed low-cost, practical methods for detecting and quantifying microplastics in seawater samples, addressing the lack of standardized protocols. Consistent, affordable detection methods are essential for expanding global microplastic monitoring and enabling meaningful comparisons across different regions and studies.
The transport and vertical distribution of microplastics in the Mekong River, SE Asia
Researchers measured microplastic levels throughout the water column of the Mekong River in Cambodia and Vietnam, finding concentrations increased significantly from rural to urban areas. Most microplastics were fibers, predominantly polyester, and 86% were transported within the water column rather than at the surface. The study reveals that surface-only sampling methods substantially underestimate actual microplastic levels in major rivers.
Microplastic contamination in the yangtze river: Evaluating pollution levels and the need for standardized research methods
This review synthesizes data from 21 studies to assess microplastic pollution levels across the Yangtze River Basin, characterizing particles by abundance, size, shape, and polymer type while applying strict QA/QC protocols and highlighting the critical need for standardized research methods.
First attempt to measure macroplastic fragmentation in rivers
Researchers developed the first method to directly measure how large plastic debris fragments into microplastics while traveling through rivers. They found that river transport causes significant breakdown of plastic waste into smaller pieces, confirming that rivers are major producers of secondary microplastics. This is important for understanding where microplastics come from, since rivers eventually carry these particles to oceans and drinking water sources.
Variance and precision of microplastic sampling in urban rivers
Researchers assessed the variance and precision of microplastic sampling methods in urban rivers, finding that high spatial and temporal variability in microplastic concentrations requires carefully designed sampling strategies to obtain representative measurements and reliable data for river microplastic assessments.

This review argues that current microplastic monitoring methods likely underestimate the true extent of contamination in aquatic environments, especially for small particles and fibers. The authors call for standardized, more sensitive detection methods to better inform regulation and risk assessment.
Assessment of Different Sampling, Sample Preparation and Analysis Methods Addressing Microplastic Concentration and Transport in Medium and Large Rivers Based on Research in the Danube River Basin
Monitoring microplastics in rivers is hampered by the lack of standardized methods, making it difficult to compare results across studies. This research tested three common sampling approaches on the Danube River and its tributaries, finding that each method produced meaningfully different estimates of microplastic concentrations and transport. The results underscore the urgent need for agreed-upon protocols so that data from different countries and research groups can be reliably combined to track river-to-ocean plastic pollution.
