ClearTracing Footprint and Risk of Microplastics and Microfibers in the Lakes across China
Researchers surveyed microplastic and microfiber contamination in the sediments of 102 lakes across China, identifying pollution sources and developing a new risk assessment index. They found contamination levels ranging widely and were able to separate microfiber pollution from microplastic pollution to better trace their origins. The study provides a large-scale snapshot of lake contamination and introduces a tool for evaluating ecological risk from these particles.
Comprehensive analysis of microplastics in water, sediment and fish from a large recreational lake
Researchers surveyed microplastics in water, sediment, and fish from a large recreational lake in China, finding MPs across all sampled compartments with higher concentrations near tourist facilities and boat launch areas, raising concerns about human exposure through lake recreation and consumption of contaminated fish.
[Characterization of Microplastic Pollution of Sediments from Urban Lakes].
Sediments from urban lakes in Maanshan City, China contained microplastics in both spring and summer, with fragments and fibers as the most common types. Local industrial and domestic activities were identified as the likely sources, adding to evidence of widespread microplastic contamination in freshwater sediments.
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.
Analysis on advances and characteristics of microplastic pollution in China’s lake ecosystems
Statistical data on microplastic pollution were compiled and analyzed for 86 lakes across China's lake ecosystems over the past five years, revealing widespread contamination with concentrations generally higher in lakes near urban and industrial areas. The review identifies China's heavily polluted eastern lake region as a priority for microplastic monitoring and management intervention.
Distribution characteristics and risk assessment of microplastics in Lake Bosten
Researchers systematically investigated the distribution, characteristics, and ecological risks of microplastics in Bosten Lake — China's largest inland freshwater lake — finding surface water abundances of 1.33-9.43 items/L and sediment concentrations of 152-953 items/kg dry weight dominated by white and black polypropylene fibers and fragments. Potential sources include residential activities, tourism, agriculture, and fisheries, with seasonal variation in risk and an overall high-risk designation using the potential ecological risk index.
Spatial Distribution of Microplastics in Water and Sediments of Main Rivers in Taihu Lake Basin
Microplastic abundance in water and sediments of 15 major inlet rivers to Taihu Lake in China was investigated, finding fibrous microplastics dominated and all three river types had a medium to high environmental risk rating, with navigable rivers showing the highest microplastic abundance.
Microplastic 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.
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.
Distribution and sedimentation of microplastics in Taihu Lake
Researchers surveyed microplastic abundance in water, sediment, and inflowing rivers of Taihu Lake, China's third-largest freshwater lake, finding widespread contamination with fibers as the dominant type and higher concentrations near urban and agricultural shorelines.
[Basin Distribution and Ecological Risk of Microplastics in Surface Water Bodies in China].
A comprehensive analysis of data from China's ten major river basins (2014–2023) found microplastic contamination in rivers, lakes, reservoirs, and estuaries across the country, with microplastic abundance strongly correlating with population density and economic output. Polypropylene and polyethylene were the dominant polymers, and the Haihe River Basin near Beijing was classified as high ecological risk. The study also highlighted a major data gap: far less is known about microplastics in China's less-populated northwestern regions. These findings provide a national-scale picture of where microplastic pollution is most severe and what types of plastics are driving the ecological risk.
Global patterns of lake microplastic pollution: Insights from regional human development levels
A meta-analysis of 351 lakes across 43 countries found microplastic concentrations ranging from 0.09 to 130,000 items/m3 in surface water, with fibers as the dominant shape and polyethylene, polypropylene, and PET as the most common polymers. Countries with lower human development indices actually showed higher contamination levels, suggesting that waste management capacity is a key driver of lake microplastic pollution.
Distribution Characteristics and Source Analysis of Microplastics in Urban Freshwater Lakes: A Case Study in Songshan Lake of Dongguan, China
Researchers found microplastics in both surface water and sediments of Songshan Lake, an urban freshwater lake in China, identifying fiber shapes as dominant and using principal component analysis to trace sources including atmospheric deposition, runoff, and recreational activities.

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.
Global microplastic contamination in freshwater lakes: Spatial patterns, environmental drivers, and methodological challenges
This review systematically analyzed 84 studies covering more than 300 lakes worldwide to assess global microplastic contamination in freshwater lake systems. Surface water MP concentrations ranged from below 0.001 to over 200 MP/L, with fibers and fragments dominating, polyethylene and polypropylene most common, and highest levels found in shallow, lowland, and eutrophic systems near urbanized shorelines.

Microplastics in China’s surface water systems: Distribution, driving forces and ecological risk
Researchers compiled over 14,000 samples from across China to map microplastic pollution in surface water systems using machine learning models. They found that microplastic abundance varied enormously across regions, driven by a complex mix of human activities and natural conditions. The ecological risk assessment revealed that watersheds in nearly all Chinese provinces face high to extremely high contamination levels, underscoring the urgency of nationwide management efforts.

This study measured microplastic contamination in lakes across the Inner Mongolia Plateau and found levels ranging from 0.5 to 12.6 particles per liter in water, with polypropylene being the most common type. Lakes near farmland and human activity had the highest contamination, showing that agriculture and tourism are major sources of microplastic pollution. The findings are relevant because these lakes serve as water sources for surrounding communities.
