ClearMicroplastic pollution in Chinese Rivers: A detailed analysis of distribution, risk factors, and ecological impact
Researchers aggregated data from 2,474 microplastic samples across 165 publications to assess ecological risk in Chinese rivers, finding widespread contamination with average abundance varying substantially by watershed characteristics. A revised risk assessment accounting for particle morphology and polymer toxicity raised concern levels beyond previous estimates.

This review synthesized findings on microplastic pollution across China's inland water systems — rivers, lakes, and reservoirs — documenting widespread contamination and identifying gaps in monitoring methods and research coverage.
Research Progress of Microplastics in Freshwater Sediments in China
This review synthesizes Chinese research on microplastic pollution in freshwater sediments, covering detection methods, contamination levels across river systems, sources, and the potential ecological and human health implications.
Microplastic pollution research methodologies, abundance, characteristics and risk assessments for aquatic biota in China
Researchers reviewed the current state of microplastic pollution research in China's aquatic environments, covering detection methods, abundance data, characteristics, and risk assessments for aquatic organisms. The review highlights that China's marine and freshwater environments are seriously polluted by microplastics, with ingestion by aquatic organisms posing potential ecological harm.
Pollution status of microplastics in the freshwater environment of China: a mini review
This review assessed microplastic pollution in China's freshwater environments including rivers, lakes, and reservoirs, finding widespread contamination in surface waters, sediments, and biota with variations linked to population density and industrial activity.
Identifying the characteristics of and factors driving spatiotemporal water quality variations in the Yellow River Basin, China, from 2008 to 2020
This study analyzed water quality data from the Yellow River Basin in China from 2008 to 2020, identifying pollution sources and spatial trends across the watershed. While focused on general water quality rather than microplastics specifically, such assessments provide important context for understanding pollution dynamics in large river systems.
Assessment of potential ecological risk for microplastics in freshwater ecosystems
Researchers assessed the ecological risk of microplastics across freshwater ecosystems worldwide, including rivers and lakes in China, Vietnam, Europe, and South America. While one risk method showed negligible danger, more comprehensive assessment approaches revealed extreme ecological threats at every location studied, suggesting that microplastic pollution in freshwater may be more serious than previously thought.
A new holistic perspective to assess the ecological risk of microplastics: A case study in Baiyangdian Basin, China
Researchers developed a more comprehensive method for assessing the ecological risks of microplastic pollution by considering not just concentration but also the physical and chemical properties of the particles. Applied to a Chinese wetland basin, the approach revealed that traditional methods significantly underestimate the true ecological risk, with human activity and poor water flow contributing to the highest danger zones.
Correcting microplastic pollution and risk assessment in Chinese watersheds
Researchers compiled over 2,400 samples from 165 studies to create a national dataset of microplastic pollution across Chinese watersheds and developed a novel risk assessment framework. The study found that microplastic concentrations varied enormously across seven orders of magnitude, that population density and precipitation were key drivers of contamination, and that half of sampling sites fell into dangerous or extremely dangerous ecological risk categories.
Study on water quality criteria and ecological risk assessment of microplastics in China’s surface waters
Researchers derived water quality criteria for microplastics in Chinese surface waters using species sensitivity distribution analysis across aquatic toxicity data. The resulting criteria values provide regulatory benchmarks for protecting aquatic organisms from microplastic contamination in freshwater and marine environments.
Are we underestimating the driving factors and potential risks of freshwater microplastics from in situ and in silico perspective?
Researchers combined field sampling with machine learning predictions to assess microplastic contamination in rivers of China's Yangtze River Delta, incorporating land use, hydrology, and particle properties. The study found that conventional assessments may underestimate risk by overlooking smaller particle sizes and high-density polymers, and that textile manufacturing effluents are a major underrecognized source.
[Occurrence Characteristics and Ecological Risk Assessment of Microplastic Pollution in the Yellow River Basin].
Researchers examined the spatial distribution, composition characteristics, and ecological risks of microplastic pollution across the Yellow River Basin in China, assessing contamination levels in the nation's historically significant waterway system.
Research Progress of Microplastic Pollution Status and Risk Assessment of Typical Rivers in China
Rivers across China carry substantial microplastic loads, and this review finds that abundance is closely tied to population density, with urban rivers showing higher concentrations than rural ones. More than 60% of microplastics detected in most rivers were smaller than 1 mm — the size range most readily ingested by aquatic organisms and most difficult to remove by conventional treatment. The authors identify sewage plants, surface runoff, and atmospheric deposition as the main sources, and flag gaps in current risk assessment frameworks for river microplastics.
Distribution, Sources, and Ecological Risk Assessment of Microplastics in the Lower Minjiang River
Researchers characterized microplastic abundance, morphology, and polymer composition in surface water and sediments from the lower Minjiang River in China, then used pollution load indices and ecological risk assessments alongside socioeconomic data to identify likely pollution sources and ecological impacts.
