ClearMicroplastics in Sediment and Surface Water of West Dongting Lake and South Dongting Lake: Abundance, Source and Composition
Microplastics were found in both surface water and sediments of West Dongting Lake and South Dongting Lake in China, with fibers and fragments as the dominant types and concentrations influenced by proximity to urban and agricultural land use. The study provides the first data on microplastic contamination in China's second-largest freshwater lake system.
Impacts of rainfall and lakeshore soil properties on microplastics in inland freshwater: A case study in Donghu Lake, China
Microplastic pollution in Donghu Lake, the largest urban freshwater lake in China, was investigated to examine how rainfall and lakeshore soil properties influence microplastic occurrence independent of direct human activities. Baseline microplastic abundance was 5.84 items per liter, with rainfall events significantly increasing concentrations by washing particles from surrounding soils.
Distribution and changes in microplastics in Taihu Lake and cyanobacterial blooms formed by the aggregation of Microcystis colonies
Researchers investigated microplastic distribution in the surface water and sediments of Taihu Lake, China, finding abundances of 0-3.7 items/L in surface water and 44.42-417.56 items/kg in sediments, and exploring relationships between microplastics, nutrient pollutants, and cyanobacterial bloom formation in this heavily eutrophic freshwater system.
Microplastics in surface waters of Dongting Lake and Hong Lake, China
Researchers sampled surface waters of Dongting Lake and Hong Lake in China and found microplastic contamination at both sites, with fibers as the dominant type and concentrations reflecting nearby human population density and land use.
Investigation on microplastic pollution of Dongting Lake and its affiliated rivers
Researchers surveyed microplastic contamination in Dongting Lake and its affiliated rivers in China, collecting 15 surface water and 15 sediment samples from across the lake district and finding microplastic abundances of 0.62-4.31 items/m3 in water and 21-52 items/100 g dry weight in sediments. Fibers dominated and the results indicate the lake system is a significant microplastic sink fed by surrounding river networks.
Spatial and temporal distributions of microplastics and their macroscopic relationship with algal blooms in Chaohu Lake, China
Researchers examined the spatial and temporal distribution of microplastics in Chaohu Lake, China during wet and dry seasons, finding average concentrations of 2,133 particles per cubic meter in the dry season and 1,679 in the wet season. At a macroscopic level, microplastic distribution patterns correlated with algal bloom density, nutrient levels, and population distribution.
Effects of lakeshore landcover types and environmental factors on microplastic distribution in lakes on the Inner Mongolia Plateau, China
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.
Microplastics contamination in different trophic state lakes along the middle and lower reaches of Yangtze River Basin
Researchers surveyed microplastic contamination in surface water and sediments of 18 lakes along the middle and lower Yangtze River Basin in China. They found microplastics present in all sampled lakes and identified a correlation between lake trophic state and microplastic abundance. The study suggests that wastewater discharge, which drives both eutrophication and microplastic pollution, is a common underlying factor linking these two environmental issues.
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.
Microplastic Pollution in Surface Water of Urban Lakes in Changsha, China
Microplastic concentrations were measured in eight urban lakes in Changsha, China, with researchers finding widespread contamination and identifying local land use and hydrological connectivity as key factors influencing microplastic abundance.
Microplastics in Taihu Lake, China
Researchers surveyed Taihu Lake in China — one of the largest freshwater lakes in the country — and found microplastics throughout, with concentrations and polymer composition reflecting surrounding urban and industrial inputs.
[Effects of Land Use Patterns on Soil Microplastic Pollution in the Luoshijiang Sub-watershed of Erhai Lake Basin].
A study in the Luoshijiang sub-watershed of Erhai Lake found that land use type significantly influenced soil microplastic concentrations, with farmland and riparian zones showing higher contamination than grassland and woodland areas.
Microplastics pollution in inland freshwaters of China: A case study in urban surface waters of Wuhan, China
Researchers characterized microplastic pollution in inland freshwaters across urban suburban areas of China, finding contamination that reflected land use intensity and population density in the surrounding catchments.

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.
[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.
Spatial and Temporal Variations in Phytoplankton Community in Dianchi Lake Using eDNA Metabarcoding
This paper is not about microplastic pollution. It uses environmental DNA metabarcoding to study phytoplankton communities in Dianchi Lake, China, identifying seasonal and spatial variation in algal species and the environmental factors that drive those changes.
Spatial analysis of the influence on “microplastic communities” in the water at a medium scale
