This review examines microplastic pollution in aquatic ecosystems, covering chemical, biological, and ecological processes beyond simple physical contamination and identifying priority areas for future research directions.
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.
Are We Underestimating Microplastic Contamination in Aquatic Environments?
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.
Microplastics in Natural Water: Sources and Determination
This paper reviews the sources of microplastic pollution in aquatic environments and the analytical methods used to characterize and quantify microplastic particles, covering sampling, extraction, and identification techniques relevant to freshwater and marine monitoring.
Microplastic contamination, an emerging threat to the freshwater environment: a systematic review
Researchers systematically reviewed the spread of microplastics in freshwater ecosystems — rivers, lakes, and streams — documenting their sources, how they move through water, the damage they cause to aquatic organisms, and the methods used to detect them. Their review serves as a baseline reference for future research and calls for improved waste management to protect freshwater environments from ongoing microplastic contamination.
Investigation of Microplastics Presence in the Dambovita River
Researchers investigated the presence and distribution of microplastics in the Dambovita River, contributing to growing evidence of plastic pollution in freshwater systems across Romania.
Emerging pollutant in surface water bodies: a review on monitoring, analysis, mitigation measures and removal technologies of micro-plastics.
This review examined the status of emerging pollutants — including microplastics — in Indian surface water bodies, covering monitoring methods, concentrations, mitigation strategies, and regulatory context. The authors highlight the inadequacy of existing water quality monitoring systems in India for capturing these new pollutant classes.
Knowledge about Microplastic in Mediterranean Tributary River Ecosystems: Lack of Data and Research Needs on Such a Crucial Marine Pollution Source
This review surveys the limited literature on microplastic pollution in freshwater rivers feeding the Mediterranean Sea, finding major gaps in data and inconsistent methods. The authors call for standardized monitoring protocols to better understand how rivers transport microplastics from land to the ocean.
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.
Assessment of Microplastic Pollution in River Ecosystems: Effect of Land Use and Biotic Indices
Researchers analyzed microplastic pollution in Spanish river ecosystems and found that concentrations in both water and sediment were strongly linked to surrounding urban land use. They discovered that traditional water quality assessments based on biological indicators do not capture microplastic contamination effectively. The study suggests that new monitoring approaches are needed to account for this emerging pollutant in river health evaluations.
