ClearMicroplastics 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.
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.
Distribution and Sedimentation of Microplastics in Taihu Lake
Researchers studied microplastic distribution and sedimentation in Taihu Lake, one of China's largest freshwater lakes, and its surrounding rivers. Microplastics were found throughout the lake with higher concentrations near urban and industrial areas, raising concerns for water quality and aquatic life.
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.
Microplastic pollution in Taihu Lake: Spatial distribution from the lake inlet to the lake centre and vertical stratification in the water column
Researchers mapped microplastic distribution in Taihu Lake from the inlet to the center and at different water depths. They found that concentrations were highest near the inlet and decreased toward the lake center, while vertical distribution showed accumulation patterns influenced by water movement and particle density. The study improves understanding of how microplastics move and settle within large freshwater lake systems.
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 distribution in large shallow lake sediments: Variations with offshore distance and implications for microbial communities
Researchers analyzed microplastic distribution in sediments of Taihu Lake at varying distances from shore and examined the effects on microbial communities. They found that microplastic abundance decreased with increasing distance from the shoreline, ranging from 240 to 1,120 items per kilogram. The study suggests that microplastic contamination in lake sediments can significantly alter the composition and diversity of local microbial communities.
Cyanobacterial relative enrichment over diatoms: Differential responses of plankton to microplastic pollution in the Zhanghe River, Northern China
Researchers assessed microplastic pollution and its ecological impacts on plankton communities in the Zhanghe River, China, finding that fibrous polyethylene, polypropylene, and polyamide MPs increased from upstream to downstream and were significantly associated with cyanobacterial proliferation while inhibiting diatoms, with a synergistic interaction with total phosphorus potentially amplifying eutrophication risk.
[Correlation Between Microplastics Pollution and Eutrophication in the Near Shore Waters of Dianchi Lake].
This study found a spatial correlation between microplastic pollution and eutrophication (nutrient enrichment causing algal blooms) in the nearshore waters of Dianchi Lake in China. The co-occurrence suggests that land-based pollution sources contribute both nutrient runoff and plastic waste to this freshwater ecosystem.
Distribution and characteristics of microplastics in the sediments of Poyang Lake, China
Researchers found microplastic contamination in sediments across Poyang Lake, China, with abundances ranging from 11 to 3,153 items per kilogram dry weight, and identified significant spatial variability linked to human activity and hydrological conditions.
Microplastics 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.
Microplastic characteristics differentially influence cyanobacterial harmful algal bloom microbial community membership, growth, and toxin production
Researchers investigated how different types of microplastics influence the growth and toxin production of harmful algal blooms in freshwater. They found that certain microplastic characteristics, such as shape and polymer type, significantly affected which microbial species thrived and how much toxin was produced. The study suggests that microplastic pollution may play an underappreciated role in worsening harmful algal blooms in lakes and reservoirs.
Vertical distribution of microplastics in the sediment profiles of the Lake Taihu, eastern China
Researchers analyzed vertical microplastic distribution in sediment cores from Lake Taihu, China, finding microplastics at all depths down to 50 cm with total abundances of up to 8,100 particles/kg dry weight, suggesting that surface sediment sampling significantly underestimates total microplastic storage.
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 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.
Complex microplastics significantly influence the assembly process of lake bacterial communities
Researchers examined how complex environmental microplastics -- varying in abundance, shape, size, color, and polymer type -- influence bacterial community assembly in water and sediments of Taihu Lake, China. Microplastics were associated with shifts in bacterial community composition and assembly processes, with distinct communities forming on plastic surfaces compared to surrounding lake water and sediments.
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.
