ClearLevels And Distribution Characteristics of Microplastics In Water And Sediment of A Typical Shallow Lake In Northern China
Scientists measured microplastic levels in the water and sediment of Baiyangdian Lake, a shallow lake in northern China. They found between 1,000 and 20,000 microplastic particles per cubic meter of water and up to 2,200 particles per kilogram of sediment. Despite pollution control efforts, microplastics remain widespread in this lake ecosystem.
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.

Microplastics and their interaction with microorganisms in Bosten Lake sediment
Researchers conducted the first study of microplastic contamination in the sediment of Bosten Lake in China, finding plastics throughout the lake with the highest levels near populated areas. The most common types were PET and polyethylene, primarily in fiber form. Certain bacteria associated with plastic breakdown were more abundant in heavily contaminated areas, but the presence of microplastics in this freshwater system raises concerns about their entry into the food chain.
Spatial and temporal distribution characteristics of microplastics in surface water of typical shallow lake in the middle and lower reaches of Yangtze River: A case study of Lake Baoan, Hubei Province
A seasonal sampling campaign at Lake Baoan, a shallow Yangtze River basin lake in China, found an average microplastic abundance of about 16 particles per litre in surface water, with fibers making up 40% of particles and polyethylene the dominant polymer. Microplastic concentrations peaked in winter and were lowest in summer, but showed no significant correlation with conventional water-quality indicators — suggesting that standard water-quality monitoring will miss microplastic contamination.
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.

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.
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.

Spatiotemporal and vertical distribution characteristics and ecological risks of microplastics in typical shallow lakes in northern China
Researchers studied how microplastics are distributed across water, the viscous sublayer, and sediment layers in Baiyangdian, a shallow lake in northern China, during both wet and dry seasons. They found that microplastic abundance was highest in residential areas and that the vertical distribution pattern reversed between seasons. The study highlights that seasonal water level changes significantly affect where microplastics accumulate in shallow lake ecosystems.
Occurrence and distribution of microplastics in China’s largest freshwater lake system
Researchers found high levels of microplastics in both water and sediment across China's largest freshwater lake system, Poyang Lake, with concentrations up to 1,064 particles per cubic meter in water.
